You can start and use Codex TUI to verify changes. 

Important notes:

Start interactively.
Always set RUST_LOG="trace" when starting the process.
Pass `-c log_dir=<some_temp_dir>` argument to have logs written to a specific directory to help with debugging.
When sending a test message programmatically, send text first, then send Enter in a separate write (do not send text + Enter in one burst).
Use `just codex` target to run - `just codex -c ...`

Babysit PR

Babysit a PR persistently until one of these terminal outcomes occurs: The PR is merged or closed. A situation requires user help (for example CI infrastructure issues, repeated flaky failures after retry budget is exhausted, permission problems, or ambiguity that cannot be resolved safely). Optional handoff milestone: the PR is currently green + mergeable + review-clean. Treat this as a progress state, not a watcher stop, so late-arriving review comments are still surfaced promptly while the PR remains open.

Code Review Change Size

Unless the change is mechanical the total number of changed lines should not exceed 800 lines. For complex logic changes the size should be under 500 lines.

Code Review Context

Codex maintains a context (history of messages) that is sent to the model in inference requests. No history rewrite - the context must be built up incrementally. Avoid frequent changes to context that cause cache misses. No unbounded items - everything injected in the model context must have a bounded size and a hard cap. No items larger than 10K tokens. Highlight new individual items that can cross >1k tokens as P0. These need an additional manual review.

Code Review Testing

For agent changes prefer integration tests over unit tests. Integration tests are under core/suite and use test codex to set up a test instance of codex.
