Problem

Codex text generation filters the instance's launch args down to config and feature flags before running codex exec. That drops --oss, --local-provider and -p/--profile, so for an instance configured with, for example, --oss --local-provider ollama, chat runs on the local provider but commit messages, titles and PR text run codex exec against a different provider (or fail).

This is a small, focused fix for that defect (contributing guide's "obvious bug" exception): launch args are an existing per-instance setting, and text generation should run with the same provider as chat.

Fix

The single filter is split into per-command builders in codexLaunchArgs.ts:

• codex exec keeps --oss, --local-provider and -p/--profile (all accepted by codex exec) plus the shared config and feature flags.
• codex mcp list, which rejects those flags and --strict-config, keeps only the shared config and feature flags.

Evidence

• codexLaunchArgs.test.ts and CodexTextGeneration.test.ts: three new cases ("passes exec-safe launch args into codex exec", "keeps the local model provider flags for codex exec", "drops exec-only flags for codex mcp list") fail on current main (25bf84a) and pass with the fix; 29 tests pass in the two files.
• Server typecheck and vp run check:changed pass.
• Not checked here: a live codex exec run with these flags against current main.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Background text generation now honors configured local providers and profiles. The unresolved profile/MCP concern could allow external tools to act on background prompts; profile-scoped MCP isolation needs resolution.

Walkthrough

Codex launch arguments now use separate filters for execution and MCP listing. Text generation applies the matching filter to each operation. Tests cover retained arguments for both filters and execution flag forwarding.

Changes: Codex launch argument filtering

Layer / File(s)	Summary
Define and test launch argument filters apps/server/src/provider/codexLaunchArgs.ts, apps/server/src/provider/codexLaunchArgs.test.ts	The shared parser applies separate allowlists for execution and MCP listing arguments. Tests check which arguments each filter retains.
Use filters in text generation apps/server/src/textGeneration/CodexTextGeneration.ts, apps/server/src/textGeneration/CodexTextGeneration.test.ts	Text generation uses the MCP-list filter for MCP listing and the execution filter for Codex execution. The execution test checks forwarding of --oss and --local-provider ollama.

- Around line 28-29: Update MCP server discovery alongside the
`SHARED_VALUE_FLAGS` and `SHARED_INLINE_PREFIXES` argument handling so it uses
the same effective configuration, including profile-specific MCP servers, as
`codex exec`; preserve compatibility with supported CLI versions. Add a focused
test confirming discovery includes a server enabled only by a profile.

Verified in a real dev environment

verified on linux with chrome/playwright, the running dev web app, codex 0.164.0, and real gpt-6.1-sol turns through the local proxy. projects and threads were created in the app against a real git repository.

• on github/main (6c9adfb273), selecting a profile whose provider works while the default provider is invalid makes title and commit generation fail: Model provider 'verify-missing-provider' not found.
• original head 52c227969f preserves that profile and successfully generates a commit message and commits the change (fa8dc45). ordinary chat, file reading, editing, and a resumed turn also worked.
• found and corrected the reported mcp isolation issue. a real installed computer mcp server configured only in the selected profile started during title generation on the original head. unprofiled discovery returned []; profiled discovery listed the server. correction 98c6c0872f preserves profile flags during discovery. after restarting, title regeneration and commit generation (f3119ea) succeeded without another mcp server startup. no mcp tools were requested.
• the existing regression test failed before the correction. blacksmith passed the 29 focused tests and vp run check:changed, including 31 tests, formatting, lint, knip, graphql validation, and affected typechecks. both independent reviewers approved the corrected head. all 31 github checks now pass on 98c6c0872f. the apt mirror setup failure passed after retry. the two mcp bot threads are resolved; the historical human review remains for its author to revisit.

short runtime transcript

Not verified

real ollama/lm studio inference, older codex versions, native desktop/mobile clients, macos/windows, and remote/relay connections were not exercised.

the red banner in the captures is a separate cli limitation observed on main and the pr: this installed codex app-server rejects --profile. normal chat was tested with the ordinary configuration and a shared --config override; profile-backed background generation was tested separately. this verification does not claim profile-configured chat works.
