Claude Code with GitHub

Claude Code + GitHub

Claude Code has deep GitHub integration that goes beyond basic Git commands. It can create pull requests, write PR descriptions, review code, and help resolve merge conflicts — all from your terminal.

Creating Pull Requests

After making changes, let Claude handle the entire PR process:

# Make your changes with Claude, then:
> Create a pull request for these changes with a detailed description

# Claude will:
# 1. Stage and commit the changes (if not already done)
# 2. Push the branch to GitHub
# 3. Create a PR with a well-written title and description
# 4. List all changes, motivation, and testing notes

Writing PR Descriptions

Claude generates comprehensive PR descriptions automatically:

> Create a PR with a detailed description

# Claude generates:
## Summary

## Changes
- Modified GET /api/users to accept cursor and limit params
- Added total count query for pagination metadata
- Updated UserList component with infinite scroll
- Added unit tests for pagination logic

## Testing
- All existing tests pass
- Added 4 new tests for pagination edge cases
- Manual testing on local dev server confirmed

Code Review with Claude

Use Claude to review PRs — both your own and others':

# Review the current branch's changes
> Review my changes for bugs, security issues, and style problems

# Review a specific PR (requires GitHub MCP server)
> Review PR #42 and check for any issues

Resolving Merge Conflicts

Merge conflicts are one of Claude Code's strongest use cases:

# After a failed merge or rebase:
> Resolve all merge conflicts in the current branch, keeping our
> feature changes while incorporating the latest main branch updates

# Claude will:
# 1. Identify all conflicting files
# 2. Read both versions of the code
# 3. Intelligently merge the changes
# 4. Remove conflict markers
# 5. Ask you to review before committing

Git Workflow Automation

Claude handles common Git workflows effortlessly:

# Create a feature branch and start working
> Create a branch called feature/user-settings and set up the basic
> structure for a user settings page

# Commit with conventional messages
> Commit these changes with a conventional commit message

# Rebase and clean up
> Rebase this branch onto main and squash the fix-up commits

# Cherry-pick specific changes
> Cherry-pick the auth fix from the hotfix branch

GitHub Actions Integration

Claude Code can also run in CI/CD pipelines using GitHub Actions:

# Example: Auto-review PRs with Claude Code
# .github/workflows/claude-review.yml
name: Claude Code Review
on: [pull_request]
jobs:
  review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Run Claude Code Review
        run: |
          npx @anthropic-ai/claude-code --print             "Review the changes in this PR for bugs and security issues"
        env:
          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
