Use when choosing a delegation route or managing Pylon delegation tools. ---- - -# Pylon delegation - -## Choose the route - -Keep small or tightly coupled work local. For worthwhile independent work, follow the current preferred delegation method supplied by `read_delegation_skill`: **built-in** (default) or **pylon**. When reading this repo file directly, call that tool before choosing the route; the file does not contain the user's current preference. A saved Pylon preference permits Pylon child threads without a separate request every time. Explicit user instructions override the preference, including requests to stay local or use a particular method. Enabling Pylon delegation alone is availability, not a request to use it. With the built-in preference, missing built-in agents are not a reason to fall back to Pylon. - -Delegation adds briefing, startup, and review costs. Identify the independent deliverable and useful work the parent can do concurrently; avoid delegating a tiny change just to exercise the feature unless explicitly asked to test it. Do not promise token savings without measured evidence. - -## Prepare one bounded task - -Specify the objective, relevant files, acceptance checks, exclusions, and a short final report of changes, checks, and unresolved issues. Pass only necessary context, not the full conversation. Avoid overlapping edits or doing the same work as the child. - -Omit `providerInstanceId`, `model`, and `runtimeMode` unless the user requested them. Pylon applies the configured defaults and reports the selected provider/model. Never guess provider IDs or model names from caches. Missing or unavailable defaults require the user's choice in **Settings → Integrations → Pylon delegation**; available providers/models appear in **Settings → Providers**. A child cannot have broader permissions than its parent. - -A child gets its own worktree; uncommitted parent changes are not a handoff mechanism. With **Start from origin**, even committed but unpushed changes can be absent; check `startedFromOrigin`. Identify the exact target commit or diff and review base in the brief, make them accessible to the child, and require its report to confirm the reviewed revision. Project setup scripts do not run; supply necessary setup instructions. Children cannot delegate further. - -## Run, wait, review - -1. Call `delegate_thread` with a stable `delegationKey`. Reuse that key on uncertain retries to avoid duplicate children. A reused key does not start new work; use `send_to_delegated_thread` for follow-ups. -2. Do independent work first. You may end your turn with the child still pending: while delegation is enabled, Pylon queues a parent follow-through turn when a child completes, stops, errors, or needs approval/input. Busy parents receive consolidated updates at their next eligible idle boundary. For an in-turn wait, use `delegated_thread_status` with `waitSeconds: 45`; completed or blocked children return immediately. Avoid repeated polling, inspections of unfinished files, and unchanged progress updates. -3. If approval or user input is pending, surface the blocker and direct the user to the child thread. Do not loop on immediately returning status calls. Inspect errors before retrying; do not blindly spawn replacements. -4. At completion, read `delegated_thread_result`. Expand a truncated result with `maxChars` before accepting it; at the 60,000-character maximum, inspect the child thread or request a concise handoff. Review the actual completed diff and relevant checks. A child's claim of success is not verification. Merge only within the user's authorization; nothing merges automatically. -5. Send one consolidated correction using `send_to_delegated_thread` and a stable `messageKey`. Running children reject feedback; it is not queued. Wait for completion unless an urgent correction justifies `interrupt_delegated_thread`, then wait until idle before sending it. If a message key was consumed by a rejected attempt, use a new key as instructed by the error. - -## Availability and controls - -The MCP server provides this skill through `read_delegation_skill`; read it when choosing a method for a new task, not before every status call. If delegation tools are unavailable, continue locally or explain how to enable them; do not install another orchestrator automatically. - -**Settings → Integrations → Pylon delegation** controls availability, preferred delegation method, default model, and child permissions globally or per project. Availability changes apply at the next session start. While off, the saved Pylon preference is inactive. Turning it off does not stop existing children or disable built-in subagents; stop a child in its thread. Provider usage is charged to each child's account. Pylon does not yet show a combined billed cost or enforce a delegation token budget. - -Automatic follow-through applies only to Pylon child threads; built-in agents retain provider behavior. Stopped, errored, snoozed, settled, archived, or blocked parents do not automatically resume. Pylon allows at most three automatic follow-through turns since the latest ordinary user message, then records a pause in the work log. A new user message permits further follow-through. Notifications do not authorize retrying a stopped child or approving its actions. Turning delegation off prevents further automatic parent turns without stopping existing children. diff --git a/.agents/skills/pylon-delegation/agents/openai.yaml b/.agents/skills/pylon-delegation/agents/openai.yaml deleted file mode 100644 index ad7525018d..0000000000 --- a/.agents/skills/pylon-delegation/agents/openai.yaml +++ /dev/null @@ -1,4 +0,0 @@ -interface: - display_name: "Pylon Delegation" - short_description: "Choose and manage efficient Pylon delegation" - default_prompt: "Use $pylon-delegation to choose the right delegation route and manage any requested Pylon child threads." diff --git a/apps/mobile/src/features/home/HomeRouteScreen.tsx b/apps/mobile/src/features/home/HomeRouteScreen.tsx index 489d79ba8b..00731ce5ae 100644 --- a/apps/mobile/src/features/home/HomeRouteScreen.tsx +++ b/apps/mobile/src/features/home/HomeRouteScreen.tsx @@ -5,7 +5,6 @@ import { useEffect, useMemo, useState } from "react"; import { Platform, useWindowDimensions } from "react-native"; import { NativeHeaderToolbar, NativeStackScreenOptions } from "../../native/StackHeader"; -import { withoutPairExecutors } from "@t3tools/client-runtime/state/pair"; import { useProjects, useThreadShells } from "../../state/entities"; import { usePendingNewTasks } from "../../state/use-pending-new-tasks"; import { useWorkspaceState } from "../../state/workspace"; @@ -30,8 +29,7 @@ export function HomeRouteScreen() { const { width: windowWidth } = useWindowDimensions(); const { layout } = useAdaptiveWorkspaceLayout(); const projects = useProjects(); - const threadShells = useThreadShells(); - const threads = useMemo(() => withoutPairExecutors(threadShells), [threadShells]); + const threads = useThreadShells(); const { environments: workspaceEnvironments, state: catalogState } = useWorkspaceState(); const { savedConnectionsById } = useSavedRemoteConnections(); const navigation = useNavigation(); diff --git a/apps/mobile/src/features/threads/PairStatusNotice.test.tsx b/apps/mobile/src/features/threads/PairStatusNotice.test.tsx deleted file mode 100644 index 510646df37..0000000000 --- a/apps/mobile/src/features/threads/PairStatusNotice.test.tsx +++ /dev/null @@ -1,54 +0,0 @@ -import type { PairState } from "@t3tools/client-runtime/state/pair"; -import { ProviderInstanceId, ThreadId } from "@t3tools/contracts"; -import { pairExecutorThreadId } from "@t3tools/shared/delegatedThreads"; -import type { ReactNode } from "react"; -import { renderToStaticMarkup } from "react-dom/server"; -import { describe, expect, it, vi } from "vite-plus/test"; - -vi.mock("react-native", () => ({ - View: "div", - Pressable: ({ - children, - accessibilityLabel, - }: { - children: ReactNode; - accessibilityLabel?: string; - }) => , -})); -vi.mock("../../components/AppText", () => ({ AppText: "span" })); - -import { PairStatusNotice } from "./PairStatusNotice"; - -const executorId = pairExecutorThreadId(ThreadId.make("lead-1")); -type PairOn = Extract; -const on = (phase: PairOn["phase"]): PairOn => ({ - kind: "on", - executorId, - phase, - modelSelection: { instanceId: ProviderInstanceId.make("antigravity"), model: "gemini-3-flash" }, - activity: null, -}); -const render = (state: PairState) => - renderToStaticMarkup( - {}} />, - ); - -describe("PairStatusNotice", () => { - it("says who the thread is paired with and what the executor is doing", () => { - const markup = render(on("running")); - expect(markup).toContain("Paired with Gemini 3 Flash · Working"); - expect(markup).toContain("Open executor"); - expect(markup).toContain('aria-label="Paired with Gemini 3 Flash · Working.

Discards use a unique delete id instead, because a deterministic one would replay as success -without deleting if the same child id were ever created again. - -A child counts as a crash-orphaned attempt only when it has no initial message, no session, no turn, -and a source epoch of zero. The initial message alone is not proof: rewinding a child's first message -removes it too, but leaves a session and a later source epoch behind. The next call with an orphan's key -discards it. Any failure or interruption after `thread.create` also removes the child's worktree and -deletes the thread. The worktree path and the created flag are recorded inside the uninterruptible -steps that create them, so cleanup cannot miss a resource that exists. Forced worktree removal is -limited to paths under the server's managed worktrees directory, since a thread can record any path. -After cleanup the key is consumed for good. - -Thread deletion itself never removes worktrees (the web client does that), which is why the toolkit -removes them explicitly. - -## Child state - -A turn start waiting for provider admission changes the session to `starting`, not `latestTurn`. The -state rules therefore check `starting` first, or a follow-up would read as the previous completed turn. -The pending admission id alone is not used: interrupt recovery before the provider binds stops the -session but leaves that id set until the next turn start replaces it. A first turn stopped before admission leaves a -session but no turn and is reported as interrupted, not queued forever. - -The follow-through reactor observes children with `observeDelegatedChild`, which must agree with -`deriveDelegatedThreadState` on completed children: a turn's own terminal state wins over a session -that was stopped afterwards by a restart or the idle reaper. At startup, any child whose observation -differs from the persisted one is baselined rather than delivered, because children only run inside -the server process and nothing could have observed that change live. - -A parent can also read a child's state inside its own turn, through `pair_await`, -`delegated_thread_status`, or `delegated_thread_result`. When what those return is a finished attempt -(completed, error, or interrupted), `markDelegationObservationConsumed` writes the reactor's own -`delegation.child-state` receipt for that `noticeKey` with `baseline: true`. Activities are stored -by id, so it replaces whatever the reactor recorded while the parent was busy, and the reactor's -existing rule then skips the wake. Either order of the two writes gives the same result. Running -children and children that need the user are never marked, so those wakes still happen.

An explicit provider in the call ignores the -default entirely. An explicit model without a provider keeps the default's provider but drops its model -options. With neither and no default, the call fails rather than choosing a provider. A default is -validated exactly like an explicit choice, and an unavailable one fails. The new keys are deliberately -not in `resolveProjectSettings`' disabled-provider fallback, which would otherwise swap a project's -default for the environment's without saying so. - -Provider runtime instructions and MCP tool descriptions route agents to `read_delegation_skill`. -Prime Agent uses the tool description because it does not receive Pylon runtime instructions. -The canonical repo skill is embedded in the server bundle so installed servers need no source checkout. -The read resolves the current parent project's `delegationPreference`, defaulting to built-in agents -and treating a saved Pylon preference as inactive while delegation is disabled.

Explicit user instructions -override the preference; neither availability nor preference means every task should be delegated. -Provider/model defaults are still resolved at child creation and reported in `defaultApplied`. - -## The pair executor - -The pair toolkit ([`apps/server/src/mcp/toolkits/pair`](../../apps/server/src/mcp/toolkits/pair)) -links a lead thread to one persistent executor.

The fan-out tools refuse that key. A pair is on when that thread exists and is not -archived. - -The executor is created with the lead's `branch` and `worktreePath`: it works in the lead's checkout, -so the lead reviews its own tree and no worktree is created or cleaned up. Two threads on one -checkout is already how local-mode threads behave. The executor is always created in the default -interaction mode, because a lead in plan mode plans and its executor implements. - -An executor that never ran reads as `idle`, where the fan-out derivation says `queued`: it is -created without a first message and waits for a brief. A brief to a running executor is refused -unless the lead asks to steer, and a turn can be steered once: the steer message id is derived from -the turn id, so the limit survives restarts. `pair_await` blocks inside the tool call, which costs no -tokens, up to a cap chosen by the lead's provider: long only where Pylon sets that provider's MCP -tool timeout itself. The lead does not choose the length. A live Codex lead asked for 10 to 20 -seconds at a time and looped, which is polling with a model turn per call, so any request other than -an explicit 0 waits the whole cap; the call still returns the moment the executor changes state, and -0 reads the state without waiting. Instant reads are rationed too: a lead may glance at a running -executor twice in a row, and a third `maxSeconds: 0` waits the whole cap instead (`pairAwaitPlan`), so -no argument turns the tool into a poll. Any wait, or finding the executor not running, clears the -count, which lives in memory beside the protected-path record. Its `filesChanged` covers the executor's latest turn only: one -executor serves every brief of a pair, so listing all of its checkpoints would hand the lead files it -reviewed several briefs ago. `turnCount` still counts them all. - -Pairing is session-scoped. When a provider session is prepared, `ProviderService` adds a `pair` -capability if the thread's executor exists and is not archived. The `enableAgentDelegation` setting -is not consulted: it covers what an agent starts on its own, and a pair is switched on by the user -for one thread. So `pair_start` still requires the `delegation` capability, while `pair_handoff`, -`pair_await` and `pair_stop` accept either one, and the follow-through reactor and the engine's -admission of its wake let a pair executor through with the setting off (`followThroughChildren`, -`isFollowThroughAdmitted`). Fan-out children stay silent in that case. Adapters read the `pair` -capability too. A paired Claude query denies the Agent tool (named Task in older -Claude Code), a paired Codex app-server starts with `features.multi_agent=false` and -`features.multi_agent_v2=false`, and every harness that receives Pylon instructions gets the pair -protocol in place of the delegation block. Nothing is -written to a provider's own settings, so a thread that is not paired behaves exactly as the provider -ships. A pair started mid-session reaches the lead through the `pair_start` result, which carries the -same protocol text; the tool denial applies from the next session start. Prime Agent has no tool -to deny, but it lets Pylon set one session's subagent depth, so `ProviderService` sets it to 0 right -after a paired session starts (`holdPairedAgentDepth`). That is the session's own value and leaves -Prime's global setting alone; a session adopted after a server restart keeps whatever it had, because -the depth can only change while a session is idle. A failure only logs, since the protocol already -tells the lead not to use its own subagents. - -Antigravity cannot lead and is refused by `pair_start` and by the clients, though it works as the -executor: it offers no per-session control over its own subagents and receives no Pylon -instructions. Codex can lead, but for it the protocol is the only control. Codex 0.153.4 keeps all -six `collaboration.*` tools with both flags above off (checked with -`codex exec -c features.multi_agent=false -c features.multi_agent_v2=false`), and its `t3-code` -tools are deferred behind tool discovery, so a Codex lead that is not told about the pair tools -spawns its own subagent on its own model instead. That happened in every run until Pylon's -instructions reached Codex (see the Codex protocol traps in [providers](providers.md)). With them, a -fresh Codex lead made one `pair_handoff` and one `pair_await`, a Claude executor did the work, and no -collaboration tool was called. Claude and Prime Agent leads were verified the same way, Prime on its -native daemon with an OpenAI Codex model; its log does not name tools, so the evidence is the -`pair-message:` brief on the executor and the consumed receipt on the lead. - -A paired thread does not fan out. `delegate_thread` refuses with `DelegationPairedError` while the -thread's executor exists and is not archived, and `read_delegation_skill` returns the pair protocol -there instead of the fan-out workflow. Both check the projection rather than the session's `pair` -capability, so a pair started mid-session is covered at once. This came from use, not design: a -paired Claude lead that was told to "use delegation" looked up the delegation tools, read the skill, -started two children, and never briefed its executor. The status, result, send and interrupt tools -still work, so children from before the pair can be wound down. - -The executor follows its lead. `PairLifecycleReactor` watches domain events and dispatches existing -commands: archiving, settling, or deleting a lead does the same to its executor, including an -executor that was archived when the pair was turned off. An executor's own lifecycle never echoes -back, because archiving it is how a user turns the pair off, and unarchiving a lead does not turn a -pair back on. A rewind of the lead is not blocked, since that would mean changing rewind admission in -the decider. Instead the reactor interrupts a running executor the moment the rewind is requested: the -two threads share one worktree, and an executor that kept editing would write over the restored -files. It may still write for a moment before the interrupt lands, so the web and mobile clients -refuse a rewind while the executor holds a turn, including one paused on an approval or a question, -and say why (`pairRewindBlockedReason`). The reactor stays as the backstop for any other client. The idle-session reaper skips an -executor while its lead's session is starting or running, so it is not restarted between briefs. The -reactor reads no settings: following a lead is cleanup and keeps working after delegation is turned -off. - -The same reactor sweeps once when the server starts. Turning Pair on in a draft creates the executor -before its lead thread exists, so an abandoned draft, or one whose id changed before its first send, -leaves an executor nothing will ever brief. `orphanedExecutorIds` finds them conservatively: a pair -executor that never ran, whose lead is not among the active or archived threads, and that is more -than a day old. A missing lead alone proves nothing, because that is what every freshly paired draft -looks like. The delete uses a deterministic command id, and a failed sweep only logs. - -`pair_reset` gives the executor an empty context without ending the pair. One executor serves -every brief, so its context only grows; the first one used in earnest ended a day at 126k of 128k -tokens. No command starts a thread's provider session afresh, and adding one would have meant a -contract and decider change, so the reset deletes the executor thread and creates it again under the -same id, with the same model and runtime mode and the lead's current branch and worktree. The -transcript goes; the files stay. It is refused while the executor runs, does nothing for one that -never ran, and uses unique command ids: the first create of a pair has a fixed id, and reusing it -would replay that receipt and create nothing. Between the delete and the create it waits for the -thread deletion reactor, which stops the old provider session after `thread.deleted`; the new thread -has the same id, so a brief sent straight after the reset could otherwise have its session stopped. - -A brief can name the files its lead owns, normally its tests and contract, as `protectedPaths`. -The handlers hash each file when the brief is accepted and `pair_await` reports the ones whose -content changed or that disappeared, once the executor is no longer running. This is what makes -"make these tests pass without editing them" checkable. A path that is absolute, contains `..`, or -cannot be read refuses the brief before a turn starts. A steer keeps the record, each new brief -replaces it, and a replayed `messageKey` cannot reset the baseline. The record lives in memory: a -brief-to-await cycle rarely spans a restart, and after one `pair_await` reports `null` rather than -guessing. Persisting it would have meant activity rows that both clients would then have to hide. - -`pair_handoff` also corrects the executor's location. A pair turned on from the composer creates -the executor before the lead's first turn has set up its worktree, and a lead can move to another -branch. Rather than chase that through events, an ordinary brief compares the executor's `branch` -and `worktreePath` with the lead's and dispatches one `thread.meta.update` first when they differ. -Protected paths are hashed against the root the executor is about to have, a refused path stops the -brief before anything moves, and a steer never moves a running executor. - -## Accepted limits - -- A follow-up is refused while the child is running, but a user message can arrive between the - check and the dispatch; the follow-up then steers that turn, as any turn start on a running turn - does.

Antigravity can be the -executor but cannot lead a pair, because Pylon has no way to pause its own subagents; on an -Antigravity thread **Pair** is unavailable and says why.
