Agent skill
git-workflow
Git workflow patterns including commit messages, rebase strategy, and pre-commit hooks. Use when committing, creating PRs, or managing git history. Do NOT use for code style or testing concerns -- use coding-style or testing-principles instead.

Git Workflow Patterns
Commit Message Format
<type>(<scope>): <subject>
<body>
<footer>
Types
| Type | Description |
|---|---|
| feat | New feature implementation |
| fix | Bug fixes |
| docs | Documentation changes only |
| style | Code formatting, missing semicolons, etc. |
| refactor | Code restructuring without behavior changes |
| perf | Performance improvements |
| test | Test additions or corrections |
| chore | Build process, auxiliary tools, dependencies |
Rules
- Subject line: Max 50 characters, imperative mood, no period
- Body: Wrap at 72 characters, explain WHY not WHAT
- Write in English
- Be specific and descriptive
Examples
feat(auth): add OAuth2 integration with Google
Implemented Google OAuth2 authentication flow to allow users
to sign in with their Google accounts. This includes:
- OAuth2 configuration and middleware setup
- User profile synchronization
- Session management with JWT tokens
Closes #123
fix(api): resolve race condition in payment processing
The payment webhook handler was not properly locking the
transaction record, causing duplicate charges when webhooks
arrived simultaneously. Added database-level locking to
ensure atomic transaction updates.
Pre-commit Hook Handling
CRITICAL: NEVER use --no-verify flag
Language-specific Checks
JavaScript/TypeScript:
- Linting:
npm run lint,eslint - Type checking:
npm run typecheck,tsc - Formatting:
prettier --check,npm run format - Tests:
npm test,jest,vitest
Python:
- Linting:
ruff check,flake8,pylint - Type checking:
mypy,pyright - Formatting:
black --check,ruff format - Tests:
pytest,python -m unittest
Ruby:
- Linting:
rubocop - Tests:
rspec,rake test
Go:
- Formatting:
go fmt,gofmt - Linting:
golangci-lint run - Tests:
go test
General:
- See
makefile-firstskill for command execution policy - Check package.json scripts section
- Review project documentation
Fixing Pre-commit Failures
- Analyze the error message
- Fix automatically if possible (formatting, linting)
- For type errors: Modify code to fix
- For test failures: Debug and fix
- Stage fixed files and retry commit
Rebase Strategy
When to Rebase
Use git pull --rebase to maintain linear history:
- Before pushing local commits
- When local branch is behind remote
Safety Checks
Before git operations:
- Uncommitted changes: Stash or commit before proceeding
- Remote tracking: Ensure branch tracks a remote
- Network connectivity: Verify connection to remote
- Branch protection: Check if branch has push restrictions
Pull Request Workflow
- Analyze full commit history (not just latest commit)
- Use
git diff [base-branch]...HEADto see all changes - Draft comprehensive PR summary
- Include test plan with TODOs
- Push with
-uflag if new branch
Git Fixup Pattern
During TDD, each User Story produces a clean commit history through fixup commits:
-
After GREEN phase: Create a semantic commit
bashgit add -A && git commit -m "feat(scope): description" -
After REFACTOR phase: Create a fixup commit targeting the GREEN commit
bashgit add -A && git commit --fixup HEAD -
After review fixes: Create a fixup commit targeting the relevant US commit
bashgit add -A && git commit --fixup <target-sha> -
Before push: Autosquash all fixup commits
bashGIT_SEQUENCE_EDITOR=true git rebase --autosquash origin/<base-branch>
The result is one clean commit per US in the final history.
Interleaved Commits
Git fixup! commits match their target by commit message, not by position in the log. This means interleaved normal and fixup commits from multiple USs are correctly handled by autosquash.
Before autosquash:
feat(auth): add login flow <- US-1 GREEN
fixup! feat(auth): add login flow <- US-1 REFACTOR
fixup! feat(auth): add login flow <- US-1 review fix
feat(auth): add password reset <- US-2 GREEN
fixup! feat(auth): add password reset <- US-2 REFACTOR
After git rebase --autosquash:
feat(auth): add login flow <- US-1 (REFACTOR + fix absorbed)
feat(auth): add password reset <- US-2 (REFACTOR absorbed)
Each fixup is absorbed into the commit whose message it matches, regardless of intervening commits.
Safe Force Push
Rule: Never use git push --force. Always use git push --force-with-lease.
Parallel Work
Prefer git worktree over git stash for parallel work.
Regression Hunting
Use git bisect run <test-command> for automated regression hunting.

agent-ops-spec
Manage specification documents in .agent/specs/. Use when user provides requirements, acceptance criteria, or feature descriptions that need to be tracked and validated against implementation.
majiayu000/claude-skill-registry
agent-ops-state
Maintain .agent state files. Use at session start, after meaningful steps, and before concluding: read/update constitution/memory/focus/issues/baseline consistently.
