gh
GitHub CLI (gh) for repository management, rulesets, releases, PRs, and issues. This skill is triggered when the user says things like "create a GitHub PR", "list GitHub issues", "set up branch protection", "create a ruleset", "configure GitHub rulesets", "create a GitHub release", "clone this repo", or "manage GitHub repository settings".
