Agent Skills
Open standard for extending AI agents with specialized knowledge and workflows. A skill is a folder containing a SKILL.md file with YAML frontmatter and instructions, optionally bundling scripts, references and assets. Loaded through progressive disclosure so many skills cost little context until used. Originally developed by Anthropic and released as an open standard.
Also known as SKILL.md, Skills.
Providers that carry Agent Skills 73
These providers' own APIs.json profiles carry Agent Skills as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score; the top 60 of 73 are shown, and the tag page lists them all.
