Agent Skills Hub

About

What are agent skills?

Agent skills package instructions, scripts, and reference material into a single folder (SKILL.md) so an AI agent can perform a specific task better. Claude, ChatGPT/Codex, Cursor, Gemini CLI, and GitHub Copilot all support the same format.

About this site

We collect skills from across the web and show which agents they work with and how to install them. Each skill belongs to its original author, and we always link to the source.

Writing Plans

A Superpowers skill that breaks a spec into bite-sized, testable 2–5 minute tasks in a detailed implementation plan.

What it does

  • Breaks work into TDD steps: failing test, verify, implement, verify, commit
  • Maps file structure and responsibilities up front
  • Gives exact file paths, code, commands, and expected output for each step
  • Reviews the plan with a subagent, then executes per task or in batches

When to use it

Great for planning a large multi-step task before handing it to an agent so it doesn't lose its way.

How to install

  1. Run the command below in your terminal. Pick the agents you use (Claude Code, Codex, Cursor, Gemini CLI, Copilot, and more) and it installs into the right folder.
