Install one, run it, keep what it makes. A free account, no card.

Every skill starts as finished work

We make the deliverable first, a promo, a page, a deck, and only then write the instructions, templates and scripts that let your agent make it again. When a skill builds on open-source work, its page says whose.

Questions

What is an Agent Skill?

A folder with a SKILL.md file plus templates and scripts. Your agent loads it when the task matches and follows it to make one specific kind of thing.

Will it work with my agent?

Yes, if your agent reads Agent Skills: Claude Code, Codex, Cursor, Gemini CLI, OpenCode and others. Each skill page lists the agents we tested it on.

Do I need an API key?

Not to install. Most skills run fully on your machine. A few call an image or video model with your own key; the skill page says so before you buy.

Can I use what it makes commercially?

Yes. Ads, client work and products you sell are all fine. You can't resell or share the skill package itself.

Isn't some of this on GitHub already?

Some of the building blocks are, and we credit every one. You pay for the finished skill: art-directed, tested, sized for real platforms, kept working, and installed in one line.

How do updates work?

Run the install command again with --force, or download the latest ZIP from the skill page. Paid plans include every update.

Ready to give your agent better taste?

Connect once, then install any skill straight from your agent.
