A package manager for AI agent prompts

What it does

skills is a CLI that treats AI agent instructions like software packages. It reads SKILL.md files—markdown with YAML frontmatter defining a name and description—and places them into the agent-specific directories that tools like Claude Code, Cursor, and Codex expect. You can install from GitHub, GitLab, or local paths, scope them per-project or globally, and choose symlinks or copies.

The interesting bit

Instead of waiting for the agent ecosystem to agree on a protocol, skills acts as a filesystem polyfill: it maps the same standard SKILL.md into .claude/skills/, .cursor/skills/, .codex/skills/, and more than 50 other locations. It is pragmatic standardization through plumbing.

Key highlights

• Supports 50+ agents, from mainstream tools to niche ones, each with their own directory mapping
• Skills are plain markdown with YAML frontmatter, so they are diffable, reviewable, and live naturally in git repos
• skills use lets you generate a one-shot prompt without installing anything permanently
• skills find offers interactive or keyword search for skills
• Install sources include GitHub shorthand, full URLs, GitLab, arbitrary git remotes, and local paths

Verdict

Worth a look if your team is bouncing between multiple AI agents and wants consistent conventions. If you have pledged allegiance to a single tool, you probably do not need the abstraction yet.
