Agent Skills (agentskills.io)

Agent Skills is an open format and specification for AI agent skills: markdown-based instructions that IDEs and agents can load as slash commands or reusable behaviors.

Format

  • SKILL.md — One markdown file per skill, with YAML frontmatter (name, description, optional disable-model-invocation).
  • Structure — Overview, Definitions, Prerequisites, Steps, Tools, Guidance (per Agent Skills spec).
  • No compilation — Skills are plain markdown; tools like the skills CLI install them by copy or symlink.

Adoption

  • Cursor — Loads skills from .cursor/skills/ or ~/.cursor/skills/. Prefer Copy (not Symlink) so Cursor lists and runs skills reliably. See Getting Started for install.
  • Other environments — Check your IDE or agent docs for Agent Skills support.
