description: Cache a remote git repository as a reusable local checkout so repeated reads reuse it instead of re-cloning. Trigger whenever a remote repo comes up as reference — the user pastes a GitHub/GitLab/Bitbucket URL, a git@… address, or owner/repo shorthand, or asks you to "look at", "check out", "clone", or "use as reference" a repo you don't have locally.
Keep one reusable local checkout per remote repository instead of re-cloning, so later references reuse a stable, up-to-date, partial-clone copy.
Run bash checkout.sh <repo> --path-only to resolve the local path, then read and search there. The <repo> can be a full URL, a git@… address, or owner/repo shorthand (defaulting to github.com). Call the script again on later references to refresh — fetches are throttled to every 5 minutes, or pass --force-update to force one now. It handles parsing, cloning, and fast-forwarding; read checkout.sh for the details.
Don't edit inside the shared cache; copy it or make a worktree for task-specific changes.
