+# Committing Patterns
+
+## Pre-Commit Checklist
+
+Before staging:
+- [ ] No secrets (`.env`, API keys, tokens)
+- [ ] No debug statements (`console.log`, `print()`, `debugger`)
+- [ ] No commented-out code blocks
+- [ ] Code is formatted (prettier/ruff)
+
+## Conventional Commit Format
+
+```
+type(scope): subject
+
+body (optional - explain why, not what)
+
+footer (optional - references, breaking changes)
+```
+
+### Types
+
+| Type | When | Example |
+|------|------|---------|
+| `feat` | New feature | `feat(auth): add OAuth2 login` |
+| `fix` | Bug fix | `fix(api): handle null user in profile` |
+| `docs` | Documentation | `docs(readme): update install steps` |
+| `refactor` | Restructure, no behavior change | `refactor(db): extract query builders` |
+| `test` | Add/fix tests | `test(auth): add login edge cases` |
+| `chore` | Maintenance | `chore(deps): update React to 19` |
+| `style` | Formatting | `style: apply prettier` |
+| `perf` | Performance | `perf(query): add index on user_id` |
+
+### Subject Line Rules
+
+- Max 50 characters
+- Imperative mood: "Add" not "Added" or "Adds"
+- No trailing period
+- Capitalize first letter
+
+### Body Rules
+
+- Wrap at 72 characters
+- Explain **why**, not what (the diff shows what)
+- Use bullet points for multiple changes
+
+### Footer Patterns
+
+```
+Closes #123
+Fixes #456
+BREAKING CHANGE: removed legacy auth endpoint
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+## Staging Best Practices
+
+```bash
+# Prefer specific files over blanket add
+git add src/auth/login.ts src/auth/login.test.ts
+
+# Review what you're committing
+git diff --staged
+
+# Never commit these
+# .env, credentials.json, *.pem, *.key
+```
+
+## Commit Command Pattern
+
+```bash
+git commit -m "$(cat <<'EOF'
+feat(auth): add password reset flow
+
+- Add reset token generation with 1h expiry
+- Implement email sending via SendGrid
+- Add rate limiting (3 requests/hour)
+
+Closes #123
+
+Co-Authored-By: Claude <noreply@anthropic.com>
+EOF
+)"
+```
+
+## Amending vs New Commit
+
+- **Amend**: Only for unpushed commits, only when fixing the same logical change
+- **New commit**: Always for pushed commits, or when adding distinct changes
+- **Never amend after pre-commit hook failure** — the commit didn't happen, so amend would modify the previous commit
