Gentle AI — Branch & PR Skill

When to Use

Load this skill whenever you need to:

• Create a branch for a new fix or feature
• Open a pull request on Gentleman-Programming/gentle-ai
• Prepare changes for review

Critical Rules

1. Every PR MUST link an approved issue — Closes/Fixes/Resolves #<N> in the PR body, and that issue MUST have status:approved. PRs without this are automatically rejected by CI.
2. Exactly one type:* label — apply exactly ONE type label to the PR. CI will reject PRs with zero or multiple type labels.
3. 400-line review budget — keep PRs within 400 changed lines (additions + deletions) or request/obtain maintainer-applied size:exception with rationale documented.
4. Automated checks must pass — see the Automated Checks table below.
5. No Co-Authored-By trailers — never add AI attribution to commits.
6. No force-push to main/master — protected branch.

Workflow

1. Confirm the issue has status:approved
   gh issue view <N> --repo Gentleman-Programming/gentle-ai

2. Create a branch from main using the naming convention below

3. Implement changes following specs and design

4. Run checks locally (format + unit + E2E)

5. Commit using Conventional Commits format

6. Open a PR referencing the issue
   → Add exactly ONE type:* label
   → Fill in the PR body using the template

7. All automated checks must pass before merge

Branch Naming

Branch names must match this pattern:

^(feat|fix|chore|docs|style|refactor|perf|test|build|ci|revert)\/[a-z0-9._-]+$

Rules:

• All lowercase
• Use hyphens, dots, or underscores as separators (no spaces, no uppercase)
• Description must be short and descriptive

PR Body Format

The PR body must follow the template at .github/PULL_REQUEST_TEMPLATE.md. All sections are required unless marked optional.
