Install a Claude Code skill from a GitHub skills repository URL.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

Install a Claude Code skill from a GitHub skills repository URL.

## Steps

1. **Route the input.** Decide whether the user gave a GitHub tree URL or a repo/skill reference.
   - Completion criterion: the input is classified as exactly one of URL or reference.

2. **Extract repo and skill path.** For a tree URL of the form `https://github.com/OWNER/REPO/tree/<ref>/skills/<category>/<skill>`, extract `OWNER/REPO` and the path under `skills/` — for example, `productivity/writing-great-skills`. If the user gave `OWNER/REPO <path>` directly, use it as-is.
   - Completion criterion: both the repository and the skill path are identified.

3. **Install for Claude Code.** Run:
   ```bash
   gh skill install <repo> <skill-path> --agent claude-code
   ```
   - Completion criterion: the command exits successfully.

4. **Report result.** Show the installed skill path and any warnings.
   - Completion criterion: the user can see whether the install succeeded.

## Failure modes

- `gh` missing or unauthenticated: stop and ask the user to run `gh auth login`.
- URL with no `skills/` segment: stop and ask for a repo/skill reference.

How to install

The exact contents, by fingerprint

mdr add atman-33/workhub/install-skill@sha256:05c99ef08eef9dc1

The line at the top of this page pins the label git:20260901.114c610, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
