Agents

One skill format. Every agent.

SKILL.md is an open standard. Pick your agent to see where skills live, the exact install command and the skills worth installing first.

Anthropic

Claude Code

Claude Code is where agent skills started, and it supports the most features: skills, plugins with bundled skills, hooks and forked context. Claude loads only each skill's name and description at startup (about 100 tokens) and reads the full SKILL.md when a task matches.

Claude

In the Claude apps, skills are uploaded as ZIP files and work on every plan from Free to Enterprise once code execution is turned on. Anthropic's built-in skills for Word, Excel, PowerPoint and PDF are already active there.

Anysphere

Cursor

Cursor reads the same open SKILL.md format. Project skills live in .agents/skills, so one install serves Cursor, Codex, Gemini CLI and Copilot together.

OpenAI

Codex

OpenAI's Codex CLI and app support agent skills natively, with a built-in $skill-installer and $skill-creator. Skills trigger implicitly from their description, or explicitly with a $skill-name mention.

Google

Gemini CLI

Google's Gemini CLI loads skills from the shared .agents/skills folder, so Google's own skill packs and community skills both work.

GitHub

GitHub Copilot

GitHub Copilot's coding agent supports agent skills. The community collection github/awesome-copilot ships hundreds of them.

Windsurf
