## Hotspots

No file-size hotspots found.

## Watchlist

| File | Lines | Kind | Recommended next split |
| --- | ---: | --- | --- |
| `tests/verify_yao_cli.py` | `899` | `test` | Break broad integration assertions into focused verifier helpers when the next behavior change lands. |
| `scripts/yao_cli_parser.py` | `810` | `internal-module` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |
| `scripts/skill_report_layout.py` | `808` | `internal-module` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |
| `scripts/skill_report_model.py` | `801` | `internal-module` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |
| `tests/verify_review_studio.py` | `763` | `test` | Break broad integration assertions into focused verifier helpers when the next behavior change lands. |
| `scripts/compile_skill.py` | `734` | `cli-script` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |
| `scripts/build_skill_atlas.py` | `730` | `cli-script` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |
| `scripts/optimize_description.py` | `723` | `cli-script` | Watch this file before adding new responsibilities; extract a helper module when one concern dominates. |

## Release Rule

- `block` hotspots should be split before governed release.
- `warn` hotspots can ship only when Review Studio keeps them visible and a reviewer accepts the modularization plan.
- Do not split a file only for line count; split when a stable responsibility boundary is clear.
