Configure Git CLI

When to use this skill

Use this skill before performing git operations (clone, push, commit, etc.). Required by the codebase-fix-and-pr skill.

Prerequisites

Required environment variables:

• GITHUB_EMAIL: Email address for git commits
• GITHUB_NAME: Name for git commits
• GITHUB_PAT: GitHub Personal Access Token with repo and workflow scopes

Workflow

Step 1: Verify Git Installation

git --version

Step 2: Configure Git User Identity

git config --global user.email "${GITHUB_EMAIL}"
git config --global user.name "${GITHUB_NAME}"

Step 3: Configure Credentials

Enable credential storage and preload GitHub credentials:

git config --global credential.helper store
cat <<EOF > ~/.git-credentials
https://${GITHUB_NAME}:${GITHUB_PAT}@github.com
EOF
chmod 600 ~/.git-credentials

Step 4: Verify Configuration

git config user.email
git config user.name
git ls-remote https://github.com/test/test.git

All commands should succeed without prompting for credentials.

Success Criteria

• ✅ git --version succeeds
• ✅ git config user.email and git config user.name return correct values
• ✅ git ls-remote succeeds without prompting

Troubleshooting

Issue	Solution
Git not found	Install git using your system package manager
Authentication failed	Verify GITHUB_PAT is valid, not expired, and has repo scope
Permission denied	Check write permissions to home directory
Credentials not working	Run rm ~/.git-credentials and reconfigure
