-## Code Review Rules
-
-### Model visible context
-
-Codex maintains a context (history of messages) that is sent to the model in inference requests.
-
-1. No history rewrite - the context must be built up incrementally.
-2. Avoid frequent changes to context that cause cache misses.
-3. No unbounded items - everything injected in the model context must have a bounded size and a hard cap.
-4. No items larger than 10K tokens.
-5. Highlight new individual items that can cross >1k tokens as P0. These need an additional manual review.
-6. All injected fragments must be defined as structs in `core/context` and implement ContextualUserFragment trait
-
-### Breaking changes
-
-Search for breaking changes in external integration surfaces:
-
-- app-server APIs
-- CLI parameters
-- configuration loading
-- resuming sessions from existing rollouts
-
-### Test authoring guidance
-
-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.
-
-### Change size guidance (800 lines)
-
-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.
-
-If the change is larger, explore whether it can be split into reviewable stages and identify the smallest coherent stage to land first.
-Base the staging suggestion on the actual diff, dependencies, and affected call sites.

-### Test module organization
-
-- When adding a new test module, define its contents in a separate sibling file rather than inline in the implementation file.

-
-  ```rust
-  #[cfg(test)]
-  #[path = "parser_tests.rs"]
-  mod tests;

-## Python Development Best Practices
-
-### Ignore Python 2 compatibility
-
-This project uses Python 3+. You should not use the `__future__` module.

-If you need to worry about feature compatibility between different 3.xx point releases, check the
-closest `pyproject.toml`'s `requires-python` field to see what minimum runtime version is supported.

If using history or a non-empty path for a non-running thread, the thread_id param will be ignored.\n\nIf thread_id identifies a running thread, app-server rejoins that thread and treats a non-empty path as a consistency check against the active rollout path. Empty string path values are treated as absent.\n\nPrefer using thread_id whenever possible.",
