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.

Ponytail Repo Audit

Audits a repo like a senior dev who just inherited it: bugs, security holes, load risks, untested code, and what to delete, ranked.

What it does

  • Maps README, deploy config, dependencies, entry points, and tests first
  • Assumes an expected load and traces data flows end to end
  • Ranks by correctness, safety, load, tests, speed, then leanness
  • Changes nothing and reports in plain English

When to use it

Use it when inheriting an older project or doing a whole-repo health check before launch.

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.
