Atomic Commit	Atomic Commit helps create clean, atomic commits by analyzing changes, detecting mixed concerns, and ensuring each commit is a complete unit of work. Key words to detect are atomic, atomic commits, clean commits.

Atomic Commit

Standalone skill for non-TDD workflows. Helps create clean, atomic commits by analyzing changes and detecting mixed concerns.

Atomic Commit Definition

• Does exactly one thing (one feature/fix/refactor)
• Leaves codebase in working state (builds and tests pass)
• Can be reverted independently
• Doesn't mix unrelated concerns

Workflow

1. Analyze Changes

git status && git diff && git diff --staged

2. Detect Mixed Concerns

Look for files mixing:

• Multiple features
• Bug fixes + features
• Refactoring + new functionality
• Multiple unrelated bug fixes
• Code + documentation (unless for same feature)
• Tests for multiple features

3. Group Commits

Group files by shared purpose. Present grouping to user for confirmation.

Example:

Group 1: "Add user auth" → auth/login.ts, auth/session.ts, tests/auth/login.test.ts
Group 2: "Fix password validation" → validators/password.ts, tests/validators/password.test.ts

4. Create Each Commit

For each group:

1. Stage: git add <file1> <file2> (NO git add .)
2. Review: git diff --staged
3. Test: Run tests, ensure pass
4. Build: Run build if applicable, ensure success
5. Commit: Use conventional commit format
6. Verify: git log -1 --oneline

Conventional commit types: feat|fix|refactor|docs|test|chore|perf|style

5. Final Check

git log --oneline -n <N>

Issue Integration

• Check user message or branch name for issue number
• IF no issue: ask if user wants to create one
  • IF user does not want to provider, leave it blank
• IF yes: help write description, offer gh issue create or glab issue create
  • Include in commits: "feat: description (#42)"

Guidelines

DO: One logical change, include related tests, run tests, clear messages, issue numbers DON'T: Mix features/fixes/refactors, commit broken code, vague messages, debug code

TODO Pattern

☐ Analyze: git status/diff ☐ Identify file purposes ☐ Detect mixed concerns ☐ Group into atomic commits ☐ Confirm with user ☐ For each: stage → review → test → build → commit → verify ☐ Final review

Activation

Use when user says: "atomic", "clean commits", "break down commits", "split commits" DO NOT use for TDD workflows (use TDG skill).

Closing

"Created N atomic commits. Tests pass. Would you like to review history, push, or create PR?"
