Automate Git Commits, Branches, and PRs with Claude Code

Git takes up more time than most developers realize. Writing commit messages, naming branches, crafting PR descriptions, resolving merge conflicts. These tasks are necessary but low-value. Claude Code handles all of them, letting you focus on the code itself.

Claude Code reads the diff, understands what changed and why, and writes a commit message that actually describes the changes. No more "fix stuff" or "update files."

# Simple commit with auto-generated message
> "Commit my changes with a descriptive message"

# Conventional commits format
> "Commit using conventional commits format"
# → fix(auth): validate email format before password check

# Commit with context
> "Commit these changes — I fixed the race condition
   in the WebSocket handler"
# → fix(ws): eliminate race condition in message handler
#   by synchronizing connection state updates

# Create a well-named branch for your feature
> "Create a branch for adding OAuth2 login"
# → git checkout -b feat/oauth2-login

# Branch from a specific base
> "Create a branch for the hotfix from production"
# → git checkout -b hotfix/production-fix origin/main

This is where Claude Code saves the most time. It reads all your commits, understands the full scope of changes, and writes a PR description that reviewers can actually use.

# Complete PR flow
> "Push this branch and open a PR with a clear description"

# Claude Code will:
# 1. Push the branch to origin
# 2. Read the full diff
# 3. Write a PR title and description
# 4. Open the PR via GitHub CLI

# Review an existing PR
> "Review the PR at #42 and suggest improvements"

The real power is combining everything into a single prompt. One instruction, complete execution:

# Complete workflow in one prompt:
> "Fix the validation bug in the login form, write a test
   for it, commit with a descriptive message, and open a PR"

# Claude Code executes:
# 1. Reads the codebase to find the login form
# 2. Identifies and fixes the validation bug
# 3. Writes a unit test for the fix
# 4. Runs the test suite to verify
# 5. Stages all changes
# 6. Writes a conventional commit message
# 7. Pushes the branch
# 8. Opens a PR with a full description

Add git conventions to your CLAUDE.md so Claude Code follows your team's standards consistently:

## Git Conventions
- Use conventional commits: feat:, fix:, chore:, docs:, refactor:
- Branch naming: feat/*, fix/*, hotfix/*, chore/*
- Always run tests before committing
- PR descriptions must include: Summary, Changes, Testing
- Never force-push to main or develop

Set up a pre-commit hook via Claude Code Hooks to auto-format and lint before every commit. This ensures Claude Code's commits always pass your team's quality gates.
