Agent skills

Standalone markdown files designed for AI agents to fetch and follow. Each is a focused, copy-paste-ready playbook for one task.

What are skills?

Each skill is a single markdown file at a stable URL. Designed for agents that operate over text instructions: paste the URL into a system prompt, the agent fetches it, follows the steps. Lightweight alternative to embedding the full docs.

They're also useful for humans who want a focused, scannable cheat-sheet for one operation.
