Problem

A provider's workspace skill scan can succeed while its machine health check fails. The registry discarded every scan that carried an error status, so installed skills disappeared from the composer's $ and / menus while the provider was unhealthy.

Reproduced on Windows with Codex CLI 0.160.1: account/read returned workspace routing discovery unauthorized (401), while skills/list returned 24 skills in the same app-server. Earlier Browser captures of the missing skills:

Codex skills missing from the $ menu, before and after

Change

A provider's skill inventory is no longer gated on its health:

  • refreshWorkspaceSnapshot publishes every scan that snapshotForCwd returns. Drivers already fail the effect when a scan fails, so a returned snapshot is a real inventory. The health status and message on the provider are unchanged.
  • Codex, Cursor, Grok and Antigravity copy their slash commands from the machine snapshot, and Codex attaches none when its health check fails. If the driver does not report its own command discovery and the scan carries an error status, the registry marks the entry slashCommandsPending. The existing pending handling then keeps the last known commands instead of replacing them with []. The registry rescans the entry on the next request, so the commands come back once health recovers. Claude already reports slashCommandsPending itself and is unaffected. OpenCode and Pi discover their commands per workspace, so they now report that discovery as complete and their commands replace the old ones. OpenCode 1.x used to turn a failed command lookup into []; it now reports the commands as pending, so the last known ones are kept and the entry is rescanned.
  • Managed Codex returned its machine snapshot when the scan failed. That would now be published as the workspace inventory, so a failed scan now fails like every other driver's. This also stops a failed managed Codex scan on a healthy machine from being stored as a fresh catalog (repro 1 in [Bug]: Workspace skill catalogs retain failed discovery and discard newer scan results #16866). When managed Codex is not set up or signed out, there is nothing to scan with, so it still returns its machine snapshot's empty inventory as before.

No contract or client change. Web, desktop and mobile already retry pending entries on their existing 10-second cooldown. They also retried every 10 seconds before this change, because an unhealthy provider never got a stored scan.

Scope and approval

Submitted under the very small, focused obvious-bug exception: the registry dropped a successful scan because of an unrelated health check. There are no authentication, setting or client changes. No prior approval is claimed.

The maintainer triage of #16866 suggested fixing its failed-probe case (repro 1) together with this change. Its overlapping-scan race (repro 2) and the client retry on expired catalogs (repro 3) are out of scope.

Verification

  • New registry test publishes workspace skills while machine health is in error: it fails on main, because the scan's skills are discarded, and passes here. It checks that:
    • the provider's health error stays visible;
    • an error-state scan updates skills and keeps the last known commands as pending;
    • an empty scan clears the skills;
    • a scan whose driver reports its own command discovery replaces the commands even while health is in error;
    • a healthy rescan restores the commands and clears the pending flag.
  • Managed Codex in CodexDriver.test.ts:
    • a signed-in scan whose app-server cannot start fails instead of returning the machine snapshot (fails on main, passes here);
    • a signed-in scan whose runtime cannot start, as during a token refresh or reconnect, also fails;
    • a signed-out scan still returns the empty inventory.
  • New OpenCode driver test: a 1.x workspace scan whose command lookup fails still returns its skills and reports the commands as pending. It fails without the driver change.
  • vp test run for ProviderRegistry, CodexDriver, CodexProvider, AntigravityProvider, providerMaintenanceRunner, client-runtime/providerSkills, provider-pi/driver and provider-opencode/driver: 149 tests pass. After the OpenCode and Pi change, the ProviderRegistry, provider-opencode/driver and provider-pi/driver suites pass again (73 tests), and provider-opencode/driver passes with the 1.x test (7 tests). Targeted lint and format pass, as does a type-aware lint with type-checking (vp lint --type-aware --type-check) of the changed files. The full apps/server tsc run did not finish within the time limit on this machine.

Not checked: the failing account/read against a live Codex CLI. Clients were not run, since nothing they render changes.

Approvability

Verdict: Approved at fa5488c

Macroscope's review found this PR approvable — This is a small, self-contained server bug fix that preserves successful Codex workspace skill discovery without masking account-health errors. The internal marker is stripped before workspace snapshots are emitted, and focused tests cover success, failure fallback, and empty results.

📝 Walkthrough

Walkthrough

Codex workspace scans distinguish unauthenticated accounts from runtime or skill-probe failures. OpenCode and enabled Pi snapshots report slash-command discovery status. The registry records accepted scans and marks commands pending when an error-status result does not specify their status.

Codex returns the machine snapshot after runtime-resolution failure only for unauthenticated accounts. Other runtime and skill-probe failures remain errors. OpenCode 1.x marks failed command lookup as pending; OpenCode 2.x and enabled Pi snapshots mark command discovery as complete. Tests cover the Codex failure cases and an OpenCode 1.x command-lookup failure.

Merge Risk

Merge Risk: ⚪ Minimal · up to 8fada

The supplied evidence identifies no issue that needs correction before merge. The reported tests and checks support the change, though the full server type-check and live client behavior remain unverified.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8fada

The change preserves discovered skills during provider failures without changing access checks or granting command-execution authority. No new security issue was established. Some uncertainty remains about the confidentiality of cached command metadata when a remote service rejects discovery.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — Ordinary pending-command retention uses only the previous snapshot for the selected instance and cwd. Rebuilt instances have their workspace snapshots removed, and scans from retired instance objects cannot publish. The inspected retention path does not select another instance's cached commands.

Trust Boundaries and Controls

  • observed — Refresh authorization remains enforced against the connection's scopes. Cached OpenCode menu entries do not authorize native command execution: submission reloads the current command list, sends a native command only for a current match, and otherwise submits ordinary prompt text. Both paths use the existing SDK client and credential configuration, unchanged from the PR base.

Resilience and Maintainability Implications

  • observed — Fresh refresh already invalidates other instances' snapshots for the same cwd before discovery succeeds. Failure returns the resulting cached state, and interruption propagates without restoring those invalidated snapshots. This behavior is identical in the supplied base and head and is not an introduced rollback regression.

Comment thread apps/server/src/provider/ProviderRegistry.ts Outdated
A workspace skill scan that succeeded was discarded whenever the provider's
machine health check reported an error, so Codex skills vanished from the
composer when account/read failed while skills/list worked.

Publish every successful scan. Commands that drivers copy from a failed
health check are marked pending, so the last known commands stay and the
entry is retried. Managed Codex now fails a broken scan instead of returning
its machine snapshot as the workspace inventory, except when it is signed out
or not set up and there is nothing to scan with.
