feat(cloud-worker): mount subscription logins for the run and write refreshed tokens back - #2073
agent-relay cloud worker now mounts a workspace's subscription logins (Codex ChatGPT and Grok auth files) for the run, and writes refreshed tokens back. This is the worker half of self-hosted Coding agents (AgentWorkforce/relaycontrol, selfhost/coding-agents-subscription-logins) and mirrors how hosted Cloud mounts ~/.codex/auth.json into its sandboxes. Khaliq asked for login credentials to be held server-side the way hosted Cloud does.
Flow
Payload. A control plane that holds logins adds cliCredentials to the assignment payload: { ref, expiresAt, path: "/api/v1/workers/{workerId}/assignments/<runId>/cli-credentials", credentials: [...] }. The ref is a short-lived, run-scoped reference, not the files. The new field is optional in WorkerWorkflowPayload, and payloads without it behave exactly as before.
Fetch. Before spawning relayflows, the worker calls GET <baseUrl><path> with its worker token plus X-Cli-Credential-Ref.
Only relative /api/ paths are accepted, so the reference never leaves the control plane origin.
Write. Each file goes to <runDir>/.cli-home/<dir>/<file>, with mode 0600 inside 0700 directories.
Only CODEX_HOME and GROK_HOME may be set, and directory and file names are validated, so a hostile response can't escape the run dir.
…efreshed tokens back
When the assignment payload carries cliCredentials (a short-lived run-scoped
reference), the worker exchanges it with its worker token for the CLI auth
files, writes each 0600 in a 0700 dir inside the run dir, points
CODEX_HOME/GROK_HOME at it, sets AGENT_RELAY_SUBSCRIPTION_LOGINS for
relayflows precedence, writes back a file the CLI refreshed, and deletes the
run dir after the run.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The worker payload can include CLI credentials. The runner validates and mounts supported credentials before launching Relayflows. It attempts to save changed credentials after the run and removes the credential home.

Summary
Credential contract and materialization packages/cloud/src/worker.ts, packages/cli/src/cli/lib/cloud-worker-cli-credentials.ts, packages/cli/src/cli/lib/cloud-worker-cli-credentials.test.ts
The worker payload accepts CLI credential metadata. Helpers validate credential routes and matching files, then mount supported Codex and Grok credentials with restricted permissions. Tests cover materialization, filtering, route validation, and symlink handling.
The runner passes materialized credential environment values to Relayflows and attempts write-back on success or failure. It reports write-back failures and removes the credential home. Tests cover successful and failed runs. The changelog describes the feature.

Add a symlink-destination case to the CLI credential placement tests.
The placement test creates no symlinks. A materializer that follows a symlink at .cli-home or an auth-file path would pass it, and credentials would land outside the run directory. Add a case that places a symlink to an outside directory at .cli-home and asserts that no auth file is written there. That case fails on the current code, so materializeCliCredentials must also reject symlinked destinations.

Update materializeCliCredentials to reject symlinked credential destinations
rather than following them, including the CLI home and auth-file paths. Add a
placement test with .cli-home symlinked to an outside directory and assert that
no auth file is written there.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The subscription-login flag is built from unchecked entry.cli values, while the placement check independently accepts either home-variable name. A mislabeled response could advertise a CLI whose expected auth home was not mounted.
Relayflows may select subscription authentication without finding the corresponding login, or select the wrong provider.
This can occur when: The credential response pairs cli: 'codex' with homeEnv: 'GROK_HOME', or supplies an unsupported CLI name with an allowed home variable.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The new credential environment overrides inherited values only for homes actually materialized. If a requested login is unavailable, an inherited or payload-supplied CLI home and subscription flag can remain in the child environment.
The workflow may use an unrelated account instead of the run-scoped login or an explicit no-login fallback.
This can occur when: The worker has a personal CODEX_HOME, or the payload supplies one, while this assignment mounts no Codex file.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
credentialUrl appends the credential-ID suffix to the raw path template. An accepted template containing a query or fragment puts the suffix in that component instead of the URL pathname.
The PUT targets the collection path rather than the credential-specific endpoint, so the refreshed login may not be stored.
This can occur when: The assignment supplies a credential path such as /api/v1/workers/{workerId}/cli-credentials?scope=run and a login is refreshed.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
WorkerWorkflowPayload now permits cliCredentials, but the supplied context does not establish a production assignment producer that supplies the reference and path. The new mounting path may therefore never run outside tests.
The worker runs without the intended subscription login.
This can occur when: A production assignment needs a stored subscription login.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Any changed auth-file text is uploaded without checking that it remains a usable credential. If the CLI leaves a truncated or empty file after a failed refresh, write-back may replace the stored login with it.
Subsequent runs can lose access to a previously valid subscription login.
This can occur when: A CLI refresh partially rewrites its auth file before crashing or being terminated.

Assert the write-back request's authorization header.
The write-back test checks the PUT URL, the x-cli-credential-ref header, and the exact JSON body. It does not check the PUT's authorization header. A regression that removes or changes the worker token on write-back requests would not fail this test. The initial GET request already has this assertion in the same file.

The runner test at cloud-worker-cli-credentials.test.ts:247-315 mocks only a zero exit code. The child mock at line 265 emits exit with 0.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Write-back sends any changed string, including empty or incomplete auth-file contents, without checking that it is a usable CLI login. A refresh interrupted during an in-place rewrite could replace a valid stored credential with corrupt content.
A later run cannot authenticate with the persisted login.
This can occur when: The CLI exits while auth.json has been truncated or only partly rewritten.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
An unreadable or missing mounted file is skipped as if it were unchanged. If a CLI rotated a token but the final file cannot be read, neither failed nor the runner's completion summary identifies the lost write-back.
The worker removes the credential home and reports no credential-storage failure, leaving the control plane with the old token.
This can occur when: A CLI rotates its token and then leaves auth.json inaccessible or replaces it with an unsupported file type before the child exits.

Materialization writes and tracks auth content without the 256-KiB limit used later by readRegularFile. If a mounted file grows beyond that limit when the CLI refreshes it, write-back silently skips the changed file and does not report a failed login.
The refreshed credential is deleted during cleanup without being stored or named as a write-back failure.
This can occur when: A CLI refresh leaves a regular auth.json larger than 256 KiB.

Assert redirect: 'error' on the credential GET and PUT requests.
The controlPlane mock records url, method, headers, and body, but not RequestInit.redirect. No test returns a 3xx response. If redirect: 'error' is removed from either the GET or the PUT, the suite still passes. Record redirect in the mock and assert it for each request. This protects the refusal of redirects, which keeps the worker token and credential reference from being resent to another location.
Next to the existing header assertions, add expect(getCall.redirect).toBe('error'); for the GET. Add the same assertion for each PUT call in the write-back test.

Add a regression test for the long-error warning placement.
When the original error is longer than about 416 characters, the warning moves ahead of it (lines 284-287). The failure report keeps only the first 500 characters of the message. If a later change always appended the warning, a long error would push the warning out of the reported message.
The only warning test uses a short error. It covers only the append branch, so it does not detect this change.
Add a test with an original error longer than 500 characters. Assert that the reported message, which is the first 500 characters of the error, contains the warning text. Asserting only on the thrown error does not catch this regression.

swaps. Establish a safe descendant-traversal mechanism before applying chmod,
and if none is available, avoid changing descendants rather than weakening the
existing guard.
- Around line 105-106: Ensure the run-ID validation or login-directory path
helper prevents a run’s login home from overlapping another run’s directory.
Reject run IDs beginning with a dot or place login homes outside runs/,
preserving per-run cleanup isolation.
- Around line 355-359: Restore mode-000 directories without requiring a
successful read-only open. Update the restore flow around fsp.open to apply the
needed mode using a symlink-safe approach that still refuses symlinks; preserve
the existing safeguards while allowing mode repair before the retry removal.

1.1.8 ships relayflows AgentWorkforce#65: a claude setup token shadows ANTHROPIC_API_KEY,
and codex/grok subscription logins shadow OPENAI_API_KEY/XAI_API_KEY, which
the cloud worker's run-scoped login files (AgentWorkforce#2073) rely on.

Summary
agent-relay cloud workernow mounts a workspace's subscription logins (Codex ChatGPT and Grok auth files) for the run, and writes refreshed tokens back. This is the worker half of self-hosted Coding agents (AgentWorkforce/relaycontrol,selfhost/coding-agents-subscription-logins) and mirrors how hosted Cloud mounts~/.codex/auth.jsoninto its sandboxes. Khaliq asked for login credentials to be held server-side the way hosted Cloud does.Flow

The ref is a short-lived, run-scoped reference, not the files. The new field is optional inWorkerWorkflowPayload, and payloads without it behave exactly as before.GET <baseUrl><path>with its worker token plusX-Cli-Credential-Ref./api/paths are accepted, so the reference never leaves the control plane origin.<runDir>/.cli-home/<dir>/<file>, with mode 0600 inside 0700 directories.CODEX_HOMEandGROK_HOMEmay be set, and directory and file names are validated, so a hostile response can't escape the run dir.CODEX_HOME/GROK_HOMEpoint at those directories and win over inherited values.AGENT_RELAY_SUBSCRIPTION_LOGINS=codex,groklets relayflows give the subscription precedence overOPENAI_API_KEY/XAI_API_KEY(fix(core): subscription logins win over API keys for their CLI relayflows#65).PUT .../cli-credentials/<id>.Tests
