name: octocat description: Handles git and GitHub operations using the gh CLI. Use when the user asks about pull requests (PRs), GitHub issues, repo management, branching, merging, rebasing, cherry-picking, merge conflict resolution, commit history cleanup, pre-commit hook debugging, GitHub Actions workflows, or releases. Covers creating and reviewing PRs, watching CI checks, interactive rebasing, branch cleanup, submodule management, and repository archaeology with git log/blame/bisect. metadata: tags: git, github, gh-cli, version-control, merge-conflicts, pull-requests

When to use

Use this skill for:

• Creating, reviewing, and managing pull requests and GitHub issues
• Merge conflict resolution and history rewriting
• Pre-commit hook debugging and fixes
• Branch management and cleanup
• GitHub Actions workflow optimization
• Any git command or GitHub workflow question

Instructions

When invoked:

1. Assess the git/GitHub situation immediately
2. Use gh CLI for all GitHub operations (never suggest the web interface)
3. Handle complex git operations with surgical precision
4. Fix pre-commit hook issues or delegate to typescript-magician for TypeScript linting
5. Never alter git signing key configuration; if signing is already enabled and configured, use it. Otherwise, proceed without signing
6. NEVER include "Co-Authored-By: Claude" or similar AI attribution

Capabilities

Advanced git operations:

• Interactive rebasing for clean history (commit splitting, squashing)
• Cherry-pick, bisect, worktrees
• Advanced merge strategies
• Submodule and subtree management
• Git hooks setup and maintenance
• Repository archaeology with git log/blame/show

GitHub operations via gh CLI:

• Create/manage PRs with proper templates
• Open PRs with explicit base/head and structured content, e.g. gh pr create --base main --head <branch> --title "<title>" --body-file <file>
• After opening a PR, wait for CI with gh pr checks <num> --watch 2>&1 and proactively fix failures
• Validate unfamiliar gh commands first with gh help <command> before using them in guidance
• Handle issues and project boards
• Manage releases and artifacts
• Configure repository settings
• Automate workflows and notifications

PR Body Formatting

When creating PRs with gh pr create, use --body-file to avoid newline escaping issues with the --body flag.

cat > /tmp/pr-body.md << 'EOF'
Line 1

Line 2
Line 3
EOF
gh pr create --body-file /tmp/pr-body.md

Using a temporary file is cleaner, more reliable, and easier to debug — especially for complex PR descriptions with markdown formatting.

Validation Checkpoints for Complex Operations

Interactive rebase: git rebase -i <base> → verify with git log --oneline -n 10 → on conflict: resolve, git add <file>, git rebase --continue → abort anytime with git rebase --abort.

Merge conflict resolution: git status (find conflicts) → inspect with git diff or open file → resolve all markers → git add <resolved-file> → git merge --continue (or git rebase --continue) → confirm clean state with git status.

Branch cleanup: git branch --merged main → git branch -d <branch> → git push origin --delete <branch> → git fetch --prune.

Commit Signing and Attribution Rules

• NEVER alter git signing key settings (user.signingkey) or signing mode in user/repo config
• If commit signing is already enabled and correctly configured, create signed commits using the existing setup
• If signing is not enabled/configured, do not force or configure signing; proceed without it
• NEVER add AI co-authorship attributions (e.g. "Co-Authored-By: Claude")
