With require_body or require_signed_off_by in the config, pr-title: true failed every pull request. The title is piped to the CLI as a commit message, so it was held to rules about a commit, and the report asked to add a body and a Signed-off-by line to the title, which nobody can do.

The PR title scope now drops three rules before it is reported:

• CC011 require-body: a title has no body.
• CC012 require-signed-off-by: a title has no trailers.
• CC017 ai-author: a title has no author; the CLI read whatever git identity the runner had.

Every other message rule (type, subject length, imperative mood, AI attribution in the text) still applies to the title. Commits are unchanged.

Before and after

A FreeBSD-style config (require_body, require_signed_off_by, subject_imperative) with pr-title: true:

Tests

• A unit test for the filter in run_commit_check.
• A test against the real pinned CLI: a title fails CC011 and CC012 under that config, and passes once they are dropped.
• 339 tests pass.

Summary by CodeRabbit

• Bug Fixes
  • Pull request title checks no longer report failures for commit-body, sign-off, or commit-author rules. Other title checks remain in effect.

Walkthrough

PR-title checks now remove results for commit-only rules CC011, CC012, and CC017 before adding the title scope. Tests cover the filtered results and verify the behavior of required-body and signed-off-by rules.

Changes: PR-title rule filtering

Layer / File(s)	Summary
Filter commit-only results main.py, main_test.py	COMMIT_ONLY_RULE_IDS identifies CC011, CC012, and CC017. drop_commit_only_rules removes those checks from a scope, and PR-title evaluation applies the helper. Tests verify that the title scope retains CC001 and passes when commit-only checks are removed.

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

Change: Bug fix

Possibly related PRs

• commit-check/commit-check-action#329: Both changes select rules by scope and include CC017. PR #329 retains CC017 for commit AI-attribution checks, while this PR removes CC017 from PR-title results.

Suggested labels: bug, ai-assisted

Merge Risk: Low · up to 71d61

The change fixes PR title checks that always failed on body and sign-off rules. Two narrow edge cases remain. An AI-attribution title can still fail under the disclose policy, and a title scope with no remaining rules reports pass. Neither blocks merging, and both are quick follow-ups.

- Line 510: Update COMMIT_ONLY_RULE_IDS to include CC014 so PR title checks do
not require a disclosure trailer, which a title cannot carry. Add a title-check
test confirming that a detected AI marker passes under the disclose policy.
- Around line 515-516: Update the title-check flow around the `scope.checks`
filter so a scope with no checks remaining after removing `COMMIT_ONLY_RULE_IDS`
is reported as skipped rather than passed; preserve the existing behavior when
checks remain.
