📝 WalkthroughWalkthroughAdded a Code Comment Style section to Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🔵 Low · up to The new comment guidance omits Python class and method docstrings from its PEP 257 requirement, so future changes may not consistently document those APIs. Update both mirrored guidance files before relying on the policy as complete. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Go code follows go.dev/doc/comment (with the specific violations that most often produce verbose comments spelled out); Python follows PEP 8 for comments and PEP 257 for docstrings; and a language-neutral rule: a comment states what the code cannot show.

| - Don't document another subsystem's behavior in a declaration's comment, and don't restate an already-documented concept to set up a contrast — one defining sentence that references it is enough. | ||
| - Keep enumerations inside existing doc comments accurate when adding values, instead of commenting the new line. | ||

| **Python: conform to [PEP 8](https://peps.python.org/pep-0008/) with a 120-character line limit** (`pycodestyle --max-line-length=120` is the reference check), and follow [PEP 257](https://peps.python.org/pep-0257/) for docstrings on new or changed modules and functions — no retrofit of existing helpers is implied. |

Cover all new or changed Python docstrings.
The PEP 257 rule in .claude/CLAUDE.md and AGENTS.md names modules and functions but omits classes and methods. Use identical wording in both files, such as “new or changed Python docstrings.”

Summary
Adds a
Code Comment Stylesection to the coding-agent rules: Go code follows go.dev/doc/comment, Python follows PEP 8 (comments) and PEP 257 (docstrings), plus the language-neutral rule that a comment states what the code cannot show.Motivation / Context
Recent review rounds repeatedly trimmed comments whose verbosity traced to the same doc-comment convention violations (non-uniform const-group docs, cross-member comparisons on one member, restating already-documented concepts). Encoding the conventions in the canonical rules file prevents the next round.
