The library.

Capability you can pick up and use. Prompts, skills, tools, guides, and design systems, each built for one job and written so a person or an AI can put it to work. Free. No sign-up.

Working with an agent? Point it at capabilitylab.ai/library/llm-index.md. It’s the whole library as Markdown.

Collection · Design systems·126 systems

A UI system your agent can build from.

Each one is a live preview plus a Markdown definition: colors, type, spacing, components. Point Claude, Cursor, or Codex at the index and ask for a system that fits what you’re building.
