 Before finalizing a large change to `codex-rs`, run `just fix -p <project>` (in `codex-rs` directory) to fix any linter issues in the code. Prefer scoping with `-p` to avoid slow workspace‑wide Clippy builds; only run `just fix` without `-p` if you changed shared crates. Do not re-run tests after running `fix` or `fmt`.
 
+Also run `just argument-comment-lint` to ensure the codebase is clean of comment lint errors.

 ### Turn events
 
 The app-server streams JSON-RPC notifications while a turn is running. Each turn emits `turn/started` when it begins running and ends with `turn/completed` (final `turn` status). Token usage events stream separately via `thread/tokenUsage/updated`. Clients subscribe to the events they care about, rendering each item incrementally as updates arrive. The per-item lifecycle is always: `item/started` → zero or more item-specific deltas → `item/completed`.
