Cache and refresh remote git repositories under ~/.cache/checkouts/<host>/<org>/<repo> so future references can reuse a local copy. Use this skill when the user points you to a remote git repository as reference or you encountered a remote git repo through other means.

We split this skill into the rules it gives an agent

4 rules. 0 are common, 3 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 16 edited versions we read keep these.

  • 3

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use this skill when the user points you to a remote git repository (GitHub/GitLab/Bitbucket URLs, git@..., or owner/repo shorthand).

    line 6
  2. Distinctive:

    Default behavior is throttled refresh (every 5 minutes) to avoid unnecessary network calls.

    line 46
  3. Distinctive:

    Use that path for searching, reading, and analysis.

    line 56
  4. Distinctive:

    Prefer not to edit directly in the shared cache.

    line 61

“Common” is measured: kept by at least 6 in 10 of the 16 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Use this skill when the user points you to a remote git repository (GitHub/GitLab/Bitbucket URLs, git@..., or owner/repo shorthand).

The goal is to keep a reusable local checkout that is:

  • stable (predictable path)
  • up to date (periodic fetch + fast-forward when safe)
  • efficient (partial clone with --filter=blob:none, no repeated full clones)

Cache location

Repositories are stored at:

~/.cache/checkouts/<host>/<org>/<repo>

Example:

github.com/mitsuhiko/minijinja → ~/.cache/checkouts/github.com/mitsuhiko/minijinja

Command

bash checkout.sh <repo> --path-only

Examples:

bash checkout.sh mitsuhiko/minijinja --path-only
bash checkout.sh github.com/mitsuhiko/minijinja --path-only
bash checkout.sh https://github.com/mitsuhiko/minijinja --path-only

The script will:

  1. Parse the repo reference into host/org/repo.
  2. Clone if missing.
  3. Reuse existing checkout if present.
  4. Fetch from origin when stale (default interval: 300s).
  5. Attempt a fast-forward merge if the checkout is clean and has an upstream.

Update strategy

  • Default behavior is throttled refresh (every 5 minutes) to avoid unnecessary network calls.
  • Force immediate refresh with:
bash checkout.sh <repo> --force-update --path-only

Recommended workflow

  1. Resolve repository path via checkout.sh --path-only.
  2. Use that path for searching, reading, and analysis.
  3. On later references to the same repo, call checkout.sh again; it will find and update the cached checkout.

If edits are needed

Prefer not to edit directly in the shared cache. Create a separate worktree or copy from the cached checkout for task-specific modifications.

Notes

  • owner/repo defaults to github.com.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
