Zero-config CLI that scans your npm dependencies for `SKILL.md` directories, **validates them against the SKILL.md spec**, and installs them into Cursor / Codex / Claude / Copilot / Amp / OpenCode / Goose skill folders.

Library authors ship Agent Skills inside their npm packages. Consumers run **one command** to import every valid skill from their `node_modules` into the project-local folders their AI assistants expect — with strict frontmatter validation so accidental `skills/` folders that aren't real skills never leak through.

The design is intentionally cross-tool: npm stays the distribution substrate for version pinning, lockfiles, provenance, and audit, while `agents.skills` is the package-local declaration that tells every tool which directories are real skills. The SKILL.md format itself is introduced at [`agentskills.io`](https://agentskills.io); `skill-indexer` focuses on installing package-shipped skills into each tool's project-local folder.
