feat(sdk): hosted CLI — run --cloud --sync-code, sync, deploy/deployments/undeploy - #440
Conversation
…ansport only v1's `agent-relay cloud run --sync-code` uploaded the working tree so the hosted run executed inside it, and `cloud sync <run-id>` pulled the sandbox's diff back. Cloud already honours both for v2 runs — the v2 executor's cwd is the code mount and patch generation runs after either engine — but `flows run --cloud` never sent code, so a hosted authored flow ran in an empty directory unless a deployment supplied a repository grant. `--sync-code` now performs the same prepare → upload → submit sequence, through the Cloud API alone: `prepare` must answer with a `cloud-api` workflow-storage backend (R2), the gzip'd ustar goes to `/workflows/runs/<id>/storage/<key>` with the run-scoped credential the receipt carries, and the run is submitted against that prepared ID. Any other backend is refused as `unsupported_storage_backend` before a byte is uploaded; the SDK carries no AWS client. Sync precedes submission, so a refused backend or failed upload never leaves a launched run pointing at a tree Cloud does not hold. Inside a Git checkout the archive is `git ls-files --cached --others --exclude-standard`; outside Git, everything but `.git`/`node_modules`. The tar writer is in-process (no `tar` dependency), deterministic, and refuses paths the ustar prefix split cannot carry rather than truncating. `flows sync <run-id>` fetches `/workflows/runs/<id>/patch` and applies it with `git apply` behind a `--check`, so a conflict leaves the tree untouched. Multi-path runs are refused as `sync_unsupported`. `flows run --cloud` also accepts `--input` for an authored `.flow.ts`, parsed exactly as a local direct run parses it; without it the CLI could not submit an authored flow at all, since Cloud requires the input.

🟡 Pre-submission aborts claim unknown admission
When preparation or upload aborts, runCloudCli reports admission_unknown. The sync phase in runInCloud completes before submission, so users are wrongly warned against a safe retry.
(Refers to this code)
Learn more
runId is assigned only after runInCloud returns, so the current abort classification cannot distinguish preparation, upload, submission, and observation. Preparation and upload occur before the non-idempotent run request. Only an interruption during that final request has unknown admission.
Example: A user presses Ctrl-C while the tarball PUT is in progress. No /api/v1/workflows/run request has occurred, but the CLI prints that Cloud may have started the run and says not to resubmit.
Recommended fix: Track submission state across runInCloud and runCloudCli, or expose a typed abort/error phase. Classify prepare, packing, and upload interruptions as safely pre-admission; reserve admission_unknown for an interrupted submission request.

Fixed in fa9af73: runInCloud now calls onSubmit immediately before the one non-idempotent request. The CLI classifies an abort before that as submission_aborted ("nothing was admitted; safe to run again") and reserves admission_unknown for an interrupted submission. Test interrupts during prepare and asserts the classification and that no run POST happened.

🔴 Executable files lose launch permission
When packWorkingTree archives an executable file, ustarHeader records mode 0644 instead of its filesystem mode. Hosted commands invoking that file directly fail with permission denied.
Learn more
The archive recreates every regular file with mode 0644, regardless of its original executable bits. Tar extraction honors the header mode, so directly executed scripts and local CLI binaries stop being executable in the hosted working tree.
Example: A tracked scripts/check.sh has mode 0755, and a deterministic step runs ./scripts/check.sh. Code sync archives it as 0644; the hosted step receives permission denied instead of running the script.
Recommended fix: Pass the source file's permission bits from lstatSync into ustarHeader, encode them in the tar mode field, and add an extraction test asserting that a 0755 member remains executable.

Fixed in fa9af73: the header now carries 0755 for any file with an execute bit (0644 otherwise). Covered by the round-trip test (run.sh extracted and executed) and proven live on production — run 418dab2c gated on test -x run.sh && ./run.sh output and completed success.

🔴 Maximum-size sync exhausts memory
At 256 MiB, packWorkingTree retains file buffers, duplicates them with Buffer.concat, then allocates compressed output. Packing can exceed 768 MiB before upload and terminate memory-constrained CLI processes.
Learn more
The documented limit permits 256 MiB of regular-file content. The current implementation holds that content in chunks, copies it into one contiguous buffer, and synchronously creates another potentially similar-sized gzip buffer. Those allocations coexist, excluding Node, tar headers, and the later request body.
Example: A repository containing 256 MiB of incompressible assets passes MAX_SYNC_BYTES. Packing retains roughly 256 MiB in file buffers, 256 MiB in Buffer.concat, and about 256 MiB in gzip output before returning.
Recommended fix: Stream files through a tar writer and gzip transform into the upload request, while counting uncompressed bytes during the stream. If the HTTP layer requires a sized body, spool the compressed archive to a temporary file rather than retaining all representations in memory.

Fixed in fa9af73: the ustar is now streamed through createGzip into a spooled temp file (disposed after upload). No chunks array, no Buffer.concat; peak is one file plus the compressor window. The one whole-archive copy left is the compressed one, because the storage PUT needs a sized body — noted in the code and docs.

🟡 Git failures bypass ignore rules
When git ls-files fails inside a checkout, listTreeFiles walks the directory as if it were outside Git. Ignored and generated files enter the archive, changing synced code and potentially breaching the size limit.
Learn more
A nonzero status does not establish that root is outside Git. It also covers a missing Git executable, an unreadable or corrupt repository, and output exceeding maxBuffer. Falling back under those conditions changes the advertised archive-selection contract.
Example: In a checkout with a large ignored dist/, git ls-files exceeds the 64 MiB output buffer. The fallback walker includes dist/, so the upload differs from Git's tracked-plus-untracked selection and can hit sync_too_large.
Recommended fix: First distinguish not a git repository from operational git ls-files failures. Walk only for the former; surface a typed sync error containing a safe summary of the Git failure for every other case.

There was a problem hiding this comment.
Fixed in fa9af73: only a genuine not a git repository (per git rev-parse --is-inside-work-tree) walks the directory. A .git entry git cannot read, or an ls-files failure inside a checkout (locked index, maxBuffer, missing git), now refuses as sync_unsupported with a one-line safe summary of git's stderr. maxBuffer raised to 256 MiB to match the size limit. Tests cover the corrupt-.git and locked-index cases.

🟨 Cloud patches can overwrite control files
flows sync applies every server-returned path without a local allowlist. A compromised run can alter gates, hooks, CI configuration, or other sensitive checkout files.
Was this helpful? React with 👍 or 👎 to provide feedback.
There was a problem hiding this comment.
By design, and unchanged: the patch is the diff of the user's own run — their flow, in their synced tree — and flows sync applies it to the working tree uncommitted, exactly as v1's cloud sync did, so it is reviewed with git diff before anything is kept. git apply already refuses paths outside the tree and cannot touch .git/ (hooks). fa9af73 makes the contract explicit: every touched path is printed (deletions included) and the CLI prints "Applied to the working tree, uncommitted: review with git diff before keeping it."; docs/CLOUD.md spells it out. An allowlist would have to guess which files matter per repo; review-before-commit is the honest control here.

Fixed in fa9af73: symlinks whose target is absolute or resolves outside the tree via .. are dropped from the archive and surfaced as WARNING [sync_link_skipped] <path> on the CLI (and synced.skippedLinks in the receipt). In-tree relative links still round-trip. Tested with an absolute and a ../../ link.

…teners from the CLI
A flow that responds to GitHub issues could only be deployed through the
agentrelay.com onboarding handoff into Cloud's deploy wizard. The wizard's
one API call, `POST /api/v1/flows/deploy`, already admits a `cli:auth`
token, so this gives it a CLI:
flows deploy issue-triage.flow.ts --repo owner/name \
--on github:labels=agent --approver <handle> [--agents claude,codex] [--draft]
flows deployments
flows undeploy <deployment-id>
`deploy` means Cloud. The digest form, `flows deploy <flow>@sha256:… --to
file://…`, keeps working; the positional decides which form is meant, so no
`--cloud` flag is needed. The CLI resolves the workspace from
`/api/v1/auth/whoami`, sends the exact source with `mode: activate` (or
`draft`), the approver, the agent harnesses Cloud checks credentials for,
and the trigger sources; a GitHub source without an explicit `repository`
is scoped to `--repo`. Trigger settings are validated client-side against
the same per-provider vocabulary the launcher prefilter reads.
Credentials: every hosted verb now falls back to the `agent-relay cloud
login` store when neither `token` nor `FLOWS_CLOUD_TOKEN` is set, taking
its API URL as the default base so a login never sends its token elsewhere;
an expired login is refused with the re-login remedy. Deploy routes answer
refusals as `{ code, error }`; `cloudFetch` gains `detail: true` to surface
exactly those two fields, so `flow_model_not_connected` or
`flow_name_taken` is named instead of a bare 409.
Proven on production: deployed a label-scoped issues flow against
AgentWorkforce/flows (`DEPLOYED … listening`), listed it, removed it with
`undeploy`.

…symlinks, aborts, deletions Review findings on #440 (Devin, Cursor, CodeRabbit), each addressed: - Executable bits were written as 0644 for every file; the archive now carries 0755 for anything with an execute bit, so a synced `./run.sh` runs on the host. Proven live (run 418dab2c, gate on the script's output). - Packing held the tree, a `Buffer.concat` copy and the gzip output at once. The ustar is now streamed through `createGzip` into a spooled temporary file that is disposed after upload; peak footprint is one file plus the compressor's window, and the only whole-archive copy is the compressed one the sized PUT needs. - Any `git ls-files` failure fell back to a plain walk, which ignores `.gitignore`: a locked index or missing `git` would have uploaded `.env`. Now only a real "not a git repository" walks; a `.git` entry git cannot read, or an `ls-files` failure inside a checkout, refuses as `sync_unsupported` with a one-line safe summary. Proven live: the gitignored `.env` was absent on the host (`test ! -e .env` passed). - Symlinks whose target resolves outside the tree (absolute, or through `..`) are dropped and reported as `sync_link_skipped` warnings. - Ctrl-C during prepare, packing or upload reported `admission_unknown`. `runInCloud` now signals `onSubmit` immediately before the one non-idempotent request; earlier interruptions report `submission_aborted` and say rerunning is safe. - `flows sync` reported files from `+++ b/` lines, so deletions vanished from the list. Paths now come from `diff --git` headers. - Overwriting control files via a patch is by design and unchanged: the patch is the user's own run's diff, applied uncommitted; the CLI now says so and the doc spells out the review-before-keeping contract. Also found by the live proof: preflight probed path-like deterministic commands against the flow file's directory, while the kernel runs them in the daemon's cwd (`exec_det.rs`). Locally those coincide; on Cloud the source sits in the state directory and the code in the mount, so a synced `./run.sh` was refused `command_missing` before running. The probe now uses `process.cwd()`, which is where the step will execute. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Preflight probes path-like deterministic commands againstprocess.cwd()(Cloud code mount), not the flow file directory. Docs inCLOUD.mdand exports inindex.tsfollow the new behavior; contract tests incloud-sync.test.tsandcloud-deploy.test.ts.Reviewed by Cursor Bugbot for commit 966bacd.
