description	Claude Code only. Delegate trusted, scoped implementation to `codex exec --yolo` — building from a spec, refactors, mechanical migrations, bug fixes with a repro, tests, CI/dependency/tooling, bulk code reading — while Claude writes the spec, picks `-e` effort, and reviews every diff. Auto-routes when enabled; also `/codex-first <task>`. Keep design, ambiguous specs, tiny edits, secrets/session-only tools, and all commit/push/GitHub ops in Claude. Unsandboxed: the review gates the diff, not the machine.

Codex First

Claude Code only. Codex implements; Claude specs and reviews.

codex exec --yolo runs unsandboxed: --cd does not confine filesystem or network access. Claude's review gates the visible repo diff, not the machine — so delegate only trusted, scoped tasks and keep destructive/push ops Claude-side.

Route

Delegate (clear work orders): implementation from a spec, refactors, mechanical migrations, bug fixes with a known repro, tests/coverage, CI/dependency/tooling, bulk code exploration.

Keep in Claude: design/API/naming/UX judgment; ambiguous work where the spec the work; tiny edits (≲20 lines); secrets or session-only tools (MCP/browser/1Password); and — never delegated — commits, pushes, releases, GitHub mutations, and the review itself.
