 - **Good behavior observed**: Don't comment just to praise code that follows best practices - this adds noise. Simply approve if the code is good.
 - **Suggestions for additional tests on simple changes**: For straightforward PRs (config changes, model additions, etc.), don't suggest adding test coverage unless tests are clearly missing for new logic
 - **Obvious or self-explanatory code**: Don't ask for comments on code that is already clear
-- **`.pr/` directory artifacts**: Files in the `.pr/` directory are temporary PR-specific documents (design notes, analysis, scripts) that are automatically cleaned up when the PR is approved. Do not comment on their presence or suggest removing them.
+- **`.pr/` directory artifacts**: Files in the `.pr/` directory are temporary PR-specific documents (design notes, analysis, scripts) that are removed by hand before merge (no workflow cleans them up in this fork). Do not comment on their presence while the PR is in review; flag a `.pr/` directory only if it is still present when the PR is ready to merge.
 
 If a PR is approvable, just approve it. Don't add "one small suggestion" or "consider doing X" comments that delay merging without adding real value.
