What is a Skill File?

A skill file is a single markdown document that gives AI agents everything they need to use an API. Instead of forcing agents to parse complex OpenAPI specs or navigate multiple documentation pages, a skill file provides a concise, LLM-optimized format. Why skill files work better for agents:
  • Single context load - One file contains the complete API surface, fitting within an agent’s context window
  • Natural language first - Written in prose that LLMs understand natively, not just structured schemas
  • Actionable examples - Real request/response pairs agents can adapt, not abstract specifications
  • Prioritized information - Common operations and gotchas highlighted, not buried in exhaustive docs
What’s included:
  • API base URL and authentication
  • Available endpoints with example requests
  • MCP tools for agent integration
  • Response formats and error handling
  • Rate limits and best practices

​
