Operates GitHub through gh CLI and the REST/GraphQL APIs with explicit target, authorization, impact preview, and independent readback. Use for pull requests, issues, Actions, repositories, collaborators, teams, organization member privileges, base permissions, 2FA enforcement, repository settings, API automation, parallel or superseded PR convergence, and public or enterprise GitHub. Also use when a GitHub write returned success but the requested state did not change, or when deciding whether a setting is writable through CLI, REST, GraphQL, or only the GitHub UI.
