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. Ordinary type:* categorization — CI rejects zero or multiple type labels. Route it through the canonical issue-creation workflow contract: a current direct human instruction binds the exact target/action, target-host capability is verified, and it uses one bounded mutation and target-host readback; otherwise wait without mutation.
3. Protected policy labels — Adding or removing status:approved or size:exception requires verified policy authority from a target-host repository maintainer or repository-authorized approver for the exact target/action, plus authenticated actor target-host viewerPermission MAINTAIN or ADMIN. size:exception additionally requires documented over-budget rationale.
4. 400-line review budget — keep PRs within 400 changed lines (additions + deletions) or document the rationale required for a size:exception label.
5. Automated checks must pass — see the Automated Checks table below.
6. No Co-Authored-By trailers — never add AI attribution to commits.
7. 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
   → Declare exactly ONE type:* result in the PR body
   → Use the canonical issue-creation workflow contract before any PR-label mutation
   → 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._-]+$

Type	Example
feat/	feat/user-login
fix/	fix/duplicate-observation-insert
docs/	docs/api-reference-update
refactor/	refactor/extract-query-sanitizer
chore/	chore/bump-bubbletea-v0.26
style/	style/fix-linter-warnings
perf/	perf/optimize-catalog-loading
test/	test/add-pipeline-coverage
build/	build/update-goreleaser-config
ci/	ci/add-e2e-docker-job
revert/	revert/undo-model-picker-change

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.

Automated Checks

These checks run on every PR and all must pass before merge:

Check	What It Verifies	How to Fix
Check PR Cognitive Load	PR stays within 400 changed lines (additions + deletions) or has size:exception	Split the PR, or document the size:exception rationale and verify policy authority before its canonical workflow action
Check Issue Reference	PR body contains Closes/Fixes/Resolves #N	Add Closes #<N> to the PR body
Check Issue Has status:approved	Linked issue has the required label	Use the canonical issue-creation workflow contract only when a current direct instruction and target-host capability grant authorize the exact action; otherwise wait
Check PR Has type:* Label	Exactly one type:* label is applied to the PR	Use the canonical issue-creation workflow contract only when a current direct instruction and target-host capability authorize the exact action; otherwise wait
Unit Tests	go test ./... passes	Fix failing tests before pushing
Go Format	go run ./internal/gofmtcheck passes	Format malformed Go files before pushing
E2E Tests	cd e2e && ./docker-test.sh passes	Fix failing E2E scenarios before pushing

---

Conventional Commits

Commit messages must match this pattern:

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

Breaking Changes

Add ! after the type/scope:

feat(cli)!: rename --config flag to --config-file

BREAKING CHANGE: the --config flag has been renamed to --config-file.

Breaking changes map to type:breaking-change label.

feat(tui): add progress bar to installation steps
fix(agent): correct Claude Code detection on macOS
docs: update contributing guide
chore(deps): bump bubbletea to v0.26
