ci: tighten attribution gate — via/with split, ai-agent emails, comment vocab by JesseKoldewijn · Pull Request #21 · oxidean/oxidean.dev

JesseKoldewijn · 2026-11-12T02:20:54Z

Follow-up hardening to the merged commit-check gate (#18), from the latest CodeRabbit review round:

via/by stay loose; with/using must end the line — fixes sentence-level false positives
catches ai-agent/ai-assistant localpart bot addresses
HTML comments only flag with attribution vocabulary
drops google from vendor domains — human @google.com co-authors stay clean

Summary by CodeRabbit

Bug Fixes
- Updated commit attribution checks so Google-domain email addresses are no longer flagged as vendor identities, while AI-agent and AI-assistant email patterns are now detected.
- Refined attribution matching: “via” and “by” accept trailing context, while “with” and “using” require the vendor name at the end of the line.
- HTML attribution comments are now detected based on attribution terms.

Walkthrough

The commit check updates co-author email detection and attribution matching. It changes how attribution lines and HTML comments are flagged.

Changes: Commit attribution checks

Layer / File(s)	Summary
Co-author and attribution matching `scripts/commit-check.sh`	The co-author scan no longer treats google domains as vendor identities and now detects AI-agent and AI-assistant email patterns. The attribution rule matches `via` and `by` lines with trailing context, while `with` and `using` lines must end after the vendor name. HTML comments match attribution terms regardless of vendor name.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to 83c13

The tightened commit check can let a "built with Claude" HTML comment through and can reject some harmless comments or human co-author emails. These are narrow CI-gate edge cases with an easy workaround. Adjusting the patterns before merge would make the gate behave as the PR describes.

Explanation

The title names the main change: tightening the attribution gate in scripts/commit-check.sh. It covers the via/with split, the AI-agent email detection, and the comment vocabulary change, which are the three core edits in the summary. The title uses terms that match the code and the PR objectives. It does not cover the removal of google from vendor domains, but that is a minor detail.

- Line 93: Update the attribution pattern in the `_msg` check to recognize
“built” in HTML comments, so built-with vendor attributions are rejected while
existing attribution detection remains unchanged.
- Line 93: Update the attribution check on _msg so it detects attribution
context rather than rejecting comments merely because they contain a verb such
as “made.” Preserve detection of actual attribution while allowing ordinary
comments like “changes made for compatibility” to pass.
- Line 51: Update the AI-identity email pattern in the `_co` check so `agent.ai`
and `assistant.ai` match only as complete local-part tokens, requiring a token
boundary immediately after the identity token. Keep the existing separators and
`@` handling, and allow human addresses such as `agent.aidan@example.com`.

Continue detecting built-with attribution in HTML comments.

 previously matched the vendor rule, but it does not match the new vocabulary or any other shown rule. The check therefore accepts this AI attribution. Include built in the attribution vocabulary, or match the complete built-with-vendor form.

Do not reject ordinary comments containing attribution verbs.

 now fails the commit check even though it contains no attribution. Match attribution context rather than a verb alone, so ordinary comments can pass.
