Skill Installer

Helps install skills. By default these are sourced from https://github.com/anthropics/skills/tree/main/skills, but users can also provide other GitHub locations.

Use the helper scripts based on the task:

• List skills when the user asks what is available, or if the user uses this skill without specifying what to do.
• Install from the default repository when the user provides a skill name.
• Install from another repo when the user provides a GitHub repo/path (including private repos).

Install skills with the helper scripts.

Communication

When listing skills, output approximately as follows, depending on the context of the user's request: """ Skills from {repo}:

1. skill-1
2. skill-2 (already installed)
3. ... Which ones would you like installed? """

After installing a skill, tell the user: """ Installed into {dest}. Claude Code picks up changes under an existing ~/.claude/skills/ directory automatically. If the top-level skills directory had to be created for the first time, restart Claude Code once. """

Scripts

All of these scripts use network. Run them only in an environment that allows outbound network access.

• scripts/list-skills.py (prints skills list with installed annotations)
• scripts/list-skills.py --format json
• scripts/install-skill-from-github.py --repo <owner>/<repo> --path <path/to/skill> [<path/to/skill> ...]
• scripts/install-skill-from-github.py --url https://github.com/<owner>/<repo>/tree/<ref>/<path>
• Default repository example: scripts/install-skill-from-github.py --repo anthropics/skills --path skills/<skill-name>

Behavior and Options

• Defaults to direct download for public GitHub repos.
• If download fails with auth/permission errors, falls back to git sparse checkout.
• Aborts if the destination skill directory already exists.
• Installs into ${CLAUDE_SKILLS_DIR} when set; otherwise ~/.claude/skills/<skill-name>.
• Multiple --path values install multiple skills in one run, each named from the path basename unless --name is supplied.
• Options: --ref <ref> (default main), --dest <path>, --method auto|download|git.

Notes

• Default listing is fetched from https://github.com/anthropics/skills/tree/main/skills via the GitHub API. If it is unavailable, explain the error and exit.
• Private GitHub repos can be accessed via existing git credentials or optional GITHUB_TOKEN/GH_TOKEN for download.
• Git fallback tries HTTPS first, then SSH.
• Installed annotations come from ${CLAUDE_SKILLS_DIR} when set, otherwise ~/.claude/skills.
