Skills give Agents specialized capabilities through structured instructions. Unlike simple prompts or one-off commands, Agent Skills introduced a sophisticated approach: packaging instructions, scripts, templates, and documentation into reusable, discoverable units.
Anthropic’s decision to release Agent Skills as an open standard transformed it from a Claude-specific feature into a movement. The format’s simplicity and effectiveness attracted attention across the AI development tools ecosystem. Today, major players—Claude Code, GitHub Copilot, Cursor, OpenCode, Mistral Vibe, Antigravity, OpenAI Codex, and Kiro—have adopted the standard.
Agent Skills are elegantly simple: a folder containing a SKILL.md file. This file uses YAML frontmatter for metadata and Markdown for instructions. No complex APIs, no proprietary formats—just structured text any AI agent can understand.
