- Features that change the agent logic MUST add an integration test:
- Provide a list of major logic changes and user-facing behaviors that need to be tested.
- If unit tests are needed, put them in a dedicated test file (*_tests.rs).
- Avoid test-only functions in the main implementation.

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.
Features that change the agent logic MUST add an integration test:
- Provide a list of major logic changes and user-facing behaviors that need to be tested.
If unit tests are needed, put them in a dedicated test file (*_tests.rs). Avoid test-only functions in the main implementation.
Check whether there are existing helpers to make tests more streamlined and readable.
