Summary
Anthropic’s overview documentation for Agent Skills, a filesystem-based format packaging instructions, metadata and optional scripts into a directory an agent loads on demand. It specifies the required SKILL.md frontmatter fields and their constraints, describes a three-level progressive-disclosure loading model with stated token costs, compares availability across the API, Claude Code and claude.ai, and sets out the security assumptions the format carries.
