skill.md: An open standard for agent skills
Summary
Mintlify proposes skill.md as an open standard for agent skills, embedding a canonical skill.md at the root of docs to guide how AI agents should use the product. The post explains the rationale, design patterns (decision tables, explicit boundaries, gotchas), and how to adopt or contribute skills across documentation sites and coding agents. It also provides guidance on getting started, including replacing autogenerated skill.md with a custom version and using the skills CLI for installation.
