[codex] Fix Codex workspace skill autocomplete

[PabloSzx]

Summary

Fix Codex $skill autocomplete for project/worktree-local skills.

Root cause

Codex provider status was probed from the server process cwd, so codex app-server skills/list did not receive the active project or worktree cwd. Project-local .agents/skills entries could be parsed by Codex, but T3 Code's provider snapshot did not include them for the active workspace, leaving $create-st and similar skill queries with no matches.

Changes

• Thread optional cwd context through server.refreshProviders, the WebSocket contract, provider registry refreshes, and managed provider snapshots.
• Make managed providers remember an explicit refresh context so later background refreshes keep using the active workspace cwd.
• Probe Codex provider status with the active project/worktree cwd, falling back to the configured server cwd.
• Refresh the active Codex provider when the active workspace root changes so the existing $ skill autocomplete has the right skill list.
• Add regression coverage for Codex cwd forwarding, registry refresh context, managed-provider context reuse, and local API forwarding.

Related

Related to #2637, but this PR intentionally does not change / command suggestions or close that issue.
Related to #2048, but this PR only wires the cwd consumer for Codex; Claude project skill discovery remains separate.
Builds on the closed stale approach from #2330, with the cwd coming from the active workspace rather than only the server config cwd.
Supersedes draft #2953 with a narrower $ autocomplete-only scope.

Validation

• mise exec -- pnpm exec vp check
• mise exec -- pnpm exec vp test run apps/server/src/provider/makeManagedServerProvider.test.ts apps/server/src/provider/Layers/ProviderRegistry.test.ts apps/web/src/localApi.test.ts
• mise exec -- pnpm exec vp run --filter t3 --filter @t3tools/web --filter @t3tools/contracts typecheck

Note: full mise exec -- pnpm exec vp run typecheck currently fails on fresh origin/main in unrelated apps/desktop Effect diagnostics (effect/Scope resolution and any-in-requirements errors), before any changed package fails.

Note

Fix Codex workspace skill autocomplete by passing cwd through provider refresh

• Adds an optional cwd field to the ProviderSnapshotRefreshInput type and threads it through the refresh call chain: RPC schema → ProviderRegistry → makeManagedServerProvider → checkCodexProviderStatus.
• makeManagedServerProvider now accepts checkProvider as a function (instead of a plain Effect) and persists the last explicit refresh input so background rechecks reuse the same cwd.
• ChatView gains a useEffect that triggers a one-time Codex provider refresh with the active workspace cwd whenever the active provider is Codex and a workspace root is set, ensuring project-local skills are resolved correctly.
• Behavioral Change: ServerProviderShape.refresh changes from a plain Effect to a function accepting optional input; all driver and test call sites are updated accordingly.

Superseded by #2955, which keeps the same scoped Codex skill autocomplete fix on the requested pabloszx/ branch prefix.

Line 139 in 957ecf6

const checkProvider = checkOpenCodeProviderStatus(

The checkProvider function at line 152 ignores the input parameter, so any cwd override passed during refresh is discarded. The interface expects checkProvider: (input?: ProviderSnapshotRefreshInput) => Effect.Effect<...> where input?.cwd can override the working directory, but the current implementation captures serverConfig.cwd at instance creation time and discards runtime cwd values. This breaks the refresh contract when a different working directory is requested.

The `checkProvider` function at line 152 ignores the `input` parameter, so any `cwd` override passed during refresh is discarded. The interface expects `checkProvider: (input?: ProviderSnapshotRefreshInput) => Effect.Effect<...>` where `input?.cwd` can override the working directory, but the current implementation captures `serverConfig.cwd` at instance creation time and discards runtime `cwd` values. This breaks the refresh contract when a different working directory is requested.

Evidence trail:
- apps/server/src/provider/Drivers/OpenCodeDriver.ts lines 139-152 (REVIEWED_COMMIT): `checkProvider` pre-built with `serverConfig.cwd`, then passed as `() => checkProvider` ignoring input
- apps/server/src/provider/makeManagedServerProvider.ts lines 31-33 (REVIEWED_COMMIT): interface expects `checkProvider: (input?: ProviderSnapshotRefreshInput) => Effect.Effect<...>`
- apps/server/src/provider/makeManagedServerProvider.ts lines 130-131 (REVIEWED_COMMIT): framework passes resolved `refreshInput` to `input.checkProvider(refreshInput)`
- apps/server/src/provider/Services/ServerProvider.ts lines 6-8 (REVIEWED_COMMIT): `ProviderSnapshotRefreshInput` defines `readonly cwd?: string | undefined`
- apps/server/src/provider/Drivers/CodexDriver.ts lines 163-168 (REVIEWED_COMMIT): sibling driver correctly accepts `refreshInput?.cwd ?? serverConfig.cwd`
- apps/server/src/provider/Layers/OpenCodeProvider.ts lines 301-304 (REVIEWED_COMMIT): `checkOpenCodeProviderStatus` takes `cwd` as a parameter, so dynamic values are supported
