Summary

  • document or connect the repository’s Conventional Commits policy for pull request titles
  • validate the title on creation and every edit with the repository’s allowed types
  • use a permissionless pull_request_target workflow with no checkout, so pull request code cannot bypass the check
  • intentionally ignore intermediate commit subjects because pull requests are squash-merged using their titles

Testing

  • actionlint .github/workflows/conventional-commits.yml
  • exercised valid, breaking-change, invalid-type, uppercase-description, and trailing-space title cases locally

AI-assisted — Tool: Codex; model: OpenAI/GPT-5; version: unavailable.


Note

Low Risk
Adds a read-only title check with minimal workflow permissions and no execution of PR code; policy/docs changes only beyond that.

Overview
Adds CI enforcement of Conventional Commits on pull request titles only, aligned with squash-merge practice where the title becomes the final commit subject.

A new conventional-commits workflow runs on pull_request_target (opened, edited, reopened, synchronize) with no repo permissions and no checkout, validating the title against allowed types (feat, fix, ci, chore, etc., including new revert and security) plus optional scope and breaking !, with a lowercase-leading description. Failed titles surface a GitHub Actions error with format guidance.

AGENTS.md is updated to state that PR titles must follow the format, intermediate commit subjects are not checked, and imperative mood stays a human review rule while syntax is mechanical in CI.

📝 Walkthrough

Walkthrough

The pull request adds a Bash Conventional Commits validator, integrates it into GitHub Actions for pull requests and pushes to main, and documents the local validation command.

Changes

Conventional commit validation

Layer / File(s) Summary
Commit subject validator
mise-tasks/lint-commits
The script validates individual subjects and Git revision ranges, reports invalid subjects, rejects invalid arguments or empty ranges, and returns a failure status when validation fails.
CI and contributor integration
.github/workflows/conventional-commits.yml, AGENTS.md
The workflow validates pull request commits, titles, and pushes to main. Contributor instructions document local validation against origin/main..HEAD.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 5a7f5

The new commit-validation workflow can fail on a backwards force-push to main even though no commits were introduced. Handle rollback updates before merge to avoid an incorrect CI failure.

Poem

A rabbit checks each commit line,
With carrot-clock precision fine.
Pull requests hop through the gate,
While main keeps a tidy state.
Clean subjects make the burrow shine.

Greptile Summary

Adds a permissionless GitHub Actions check that enforces the repository’s Conventional Commit format for pull request titles and documents the corresponding title and intermediate-commit policy.

  • Validates allowed types, optional scopes and breaking-change markers, lowercase-leading descriptions, and trailing whitespace.
  • Runs on relevant pull_request_target events without checking out or executing pull request code.
  • Revises failure output so the workflow annotation contains fixed text and the submitted title is printed safely.

Confidence Score: 5/5

The pull request appears safe to merge; no actionable defects remain.

The latest change safely separates the fixed GitHub Actions annotation from the untrusted title value, and the sole previous documentation finding was manually resolved after the wording was aligned with the workflow’s lowercase-leading check.

Important Files Changed

Filename Overview
.github/workflows/conventional-commits.yml Adds a narrowly permissioned pull request title validator and safely reports invalid titles.
AGENTS.md Documents the Conventional Commit rules, allowed types, enforcement scope, and human-reviewed imperative-mood requirement.

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: help on jdx-perf-v1-ubuntu24.04-x64-tak-gha20260831.293.1-rust1.98.0-img5263c143, version on jdx-perf-v1-ubuntu24.04-x64-tak-gha20260831.293.1-rust1.98.0-img5263c143

Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run.

Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.
