Library Skills

Use this skill when a project might benefit from agent skills bundled by its installed packages, or when existing Library Skills-managed symlinks are stale, broken, orphaned, or need to be checked.

Run commands from the project root.

Agents bundle their own skills by including an .agents/skills directory. More details in Library Skills.

First-Time Setup

• Make sure project dependencies are installed first, for example with uv sync for Python projects or npm install / bun install for Node.js projects.
• Run uvx library-skills or npx library-skills to discover skills bundled by the installed packages and install selected skills interactively.
• Use uvx library-skills --all or npx library-skills --all only when all newly discovered skills should be installed without selecting individual skills.
• Use uvx library-skills --tool-skill or npx library-skills --tool-skill to copy this Library Skills tool skill into the project so future agents know how to discover, install, update, repair, and check skills.

Commands

• Run uvx library-skills or npx library-skills to discover package-provided skills, install selected new skills, and reconcile existing managed symlinks.
• Run uvx library-skills list or npx library-skills list to inspect discovered and installed skills.
• Run uvx library-skills list --json or npx library-skills list --json for machine-readable installed status.
• Run uvx library-skills scan --json or npx library-skills scan --json for discovery-only automation.
• Run uvx library-skills --check or npx library-skills --check to validate managed skill symlink state without changing files.
• Run uvx library-skills --yes or npx library-skills --yes to repair stale managed symlinks and remove orphaned managed symlinks non-interactively.
• Add --claude when .claude/skills should also be managed.
• Add --skill NAME to install a specific discovered skill by name.

Safety

• Prefer rerunning library-skills over editing managed symlinks manually.
• If installed skill symlinks are broken, dependencies may not be installed yet. Try the project's normal install command first, such as uv sync, npm install, or bun install, then rerun library-skills.
• Do not delete or overwrite hand-authored skill directories.
• Library Skills only removes managed symlinks. It should not remove copied or hand-authored skill directories.
