Overview
# Evil Martians Agent Skills
Agent Skills we build and use at Evil Martians, packaged so you can install them into your own AI coding agent.
A [skill](https://agentskills.io/specification) is a folder with a `SKILL.md` in it: a name, a description that tells the agent when to reach for it, and the instructions to follow once it does. The format is shared across agents, so these work the same in Claude Code, Codex, Cursor, Gemini CLI, and GitHub Copilot.
Browse them at **<https://evilmartians.com/agent-skills>**.
