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.

Two-Axis Code Review

Reviews a diff on two axes in parallel subagents: does it follow the repo's standards, and does it implement the spec?

Works with

What it does

  • Reviews changes since a fixed point (commit, branch, or tag)
  • Standards axis: follows the repo's documented coding rules?
  • Spec axis: faithfully implements the originating issue or spec?
  • Runs both in isolated parallel subagents and reports side by side

When to use it

Use it before opening a PR to check both code quality and whether requirements were missed.
