+description: Write conventional commit messages with type, scope, and subject when the user wants to commit changes or save work.
+---
+
+# Git Commit
+
+Creates git commits following Conventional Commits format with proper type, scope, and subject.
+
+## Quick Start
+
+```bash
+# 1. Stage changes
+git add <files>  # or: git add -A
+
+# 2. Create commit (branch commit format)
+git commit -m "type(scope): subject
+
+Body explaining HOW and WHY.
+Reference: Task X.Y, Req N"
+```
+
+## Commit Types
+
+### Regular Branch Commits (During Development)
+
+**Format**: `type(scope): subject`
+
+| Type | Purpose |
+|------|---------|
+| `feat` | New feature or functionality |
+| `fix` | Bug fix or issue resolution |
+| `refactor` | Code refactoring without behavior change |
+| `perf` | Performance improvements |
+| `test` | Test additions or modifications |
+| `ci` | CI/CD configuration changes |
+| `docs` | Documentation updates |
+| `chore` | Maintenance, dependencies, tooling |
+| `style` | Code formatting, linting (non-functional) |
+| `security` | Security vulnerability fixes or hardening |
+
+### Scope (Required, kebab-case)
+
+Examples: `validation`, `auth`, `cookie-service`, `template`, `config`, `tests`, `api`
+
+### Subject Line Rules
+
+- Max 50 characters after colon
+- Present tense imperative: add, implement, fix, improve, enhance, refactor, remove, prevent
+- NO period at the end
+- Specific and descriptive - state WHAT, not WHY
+
+## Core Workflow
+
+### 1. Review Changes
+
+```bash
+git status
+git diff --staged  # if already staged
+git diff           # if not staged
+```
+
+### 2. Stage Files
+
+```bash
+git add <specific-files>  # preferred
+# or
+git add -A  # all changes
+```
+
+**NEVER commit**:
+- `.env`, `credentials.json`, secrets
+- `node_modules/`, `__pycache__/`, `.venv/`
+- Large binary files without explicit approval
+
+### 3. Create Commit
+
+**Simple change**:
+```bash
+git commit -m "fix(auth): use hmac.compare_digest for secure comparison"
+```
+
+**Complex change (with body)**:
+```bash
+git commit -m "$(cat <<'EOF'
+feat(validation): add URLValidator with domain whitelist
+
+Implement URLValidator class supporting:
+- Domain whitelist enforcement (youtube.com, youtu.be)
+- Dangerous scheme blocking (javascript, data, file)
+- URL parsing with embedded credentials handling
+
+Addresses Requirement 31: Input validation
+Part of Task 5.1: Input Validation Utilities
+EOF
+)"
+```
+
+### 4. Verify Commit
+
+```bash
+git log -1 --format="%h %s"
+git show --stat HEAD
+```
+
+## Body Format (Recommended for Complex Changes)
+
+```
+<blank line>
+Explain HOW and WHY the change was made.
+- Use bullet points for multiple items
+- Wrap at 72 characters
+
+Reference: Task X.Y
+Addresses: Req N
+```
+
+## Git Trailers
+
+| Trailer | Purpose |
+|---------|---------|
+| `Fixes #N` | Links and closes issue on merge |
+| `Closes #N` | Same as Fixes |
+| `Co-authored-by: Name <email>` | Credit co-contributors |
+
+Place trailers at end of body after blank line. See `references/commit_examples.md` for examples.
+
+## Breaking Changes
+
+For incompatible API/behavior changes, use `!` after scope OR `BREAKING CHANGE:` footer:
+
+```
+feat(api)!: change response format to JSON:API
+
+BREAKING CHANGE: Response envelope changed from `{ data }` to `{ data: { type, id, attributes } }`.
+```
+
+Triggers major version bump in semantic-release.
+
+## Merge Commits (PR Closure)
+
+For PRs, use extended description with sections:
+
+```bash
+gh pr create --title "feat(security): implement input validation (Task 5)" --body "$(cat <<'EOF'
+## Summary
+- Input validation utilities (URLValidator, FormatValidator)
+- Secure template processor with path traversal prevention
+- API key authentication middleware
+
+## Task Breakdown
+Task 5.1: Input Validation - URLValidator, FormatValidator
+Task 5.2: Template Processing - Path traversal prevention
+Task 5.3: API Key Auth - Multi-key support, excluded paths
+Task 5.4: Security Tests - 102 path traversal tests
+
+## Requirements Covered
+Req 7, Req 9, Req 31, Req 33
+
+## Test Coverage
+- All 473 tests passing
+- Coverage: 93%
+- Pre-commit checks: passing
+EOF
+)"
+```
+
+## Integration with Other Skills
+
+### From github-pr-review
+
+When fixing review comments, use this format:
+
+```bash
+git commit -m "fix(scope): address review comment #ID
+
+Brief explanation of what was wrong and how it's fixed.
+Addresses review comment #123456789."
+```
+
+### From github-pr-creation
+
+Before creating PR, ensure all commits follow this format. The PR skill will:
+1. Analyze commits for proper format
+2. Extract types for PR labels
+3. Build PR description from commit bodies
+
+## Important Rules
+
+- **ALWAYS** include scope in parentheses
+- **ALWAYS** use present tense imperative verb
+- **NEVER** end subject with period
+- **NEVER** commit secrets or credentials
+- **NEVER** use generic messages ("update code", "fix bug", "changes")
+- **NEVER** exceed 50 chars in subject line
+- Group related changes -> single focused commit
+
+## Examples
+
+**Good**:
+```
+feat(validation): add URLValidator with domain whitelist
+fix(auth): use hmac.compare_digest for secure key comparison
+refactor(template): consolidate filename sanitization logic
+test(security): add 102 path traversal prevention tests
+```
+
+**Bad**:
+```
+update validation code           # no type, no scope, vague
+feat: add stuff                  # missing scope, too vague
+fix(auth): fix bug               # circular, not specific
+chore: make changes              # missing scope, vague
+feat(security): improve things.  # has period, vague
+```
