See every proof →

One brief, two runs.

Star counts tell you a skill is popular. A proof shows what it actually changes, on a task like yours.

Step 1

Same brief

Each proof starts with one real request, written once and never changed between runs.

“Build the launch page for Orbit, a premium wireless speaker.”

Step 2

Three runs each way

Claude builds it on its own and with the skill loaded, three independent runs per side on the same model, so you see the spread and not one lucky draw.

Without

With skill

Step 3

Side by side

Both results are live pages. Drag the divider, click around, and judge the difference yourself.

Every skill, one search.

Free to search and free to install. Every listing links straight to its source. New to skills? Read how to use one.

ProvenSkills with a proof are listed first.

Know what a skill does before it runs.

Every listing is scanned for the nine patterns a skill should never need. Check any skill on GitHub before you install it, or run the same scan on your own repositories in one command or on every pull request.

Good to know.

What is an agent skill?

A skill is a folder with a SKILL.md file that teaches a coding agent how to do one kind of job well, such as designing a page or writing tests. Claude Code, Codex, Cursor and other agents load them when the task calls for it.

How is a proof made?

We give Claude one fixed brief three times without the skill and three times with it, on the same model. Every result is saved as a live page, with the model and the skill's exact version recorded next to them.

Can a proof be repeated?

Yes. The brief, model and skill version are all recorded, so anyone can run the same comparison again. We re-run proofs when a skill changes.

What do I get for free?

Everything on the site: searching and installing all skills, every proof with all three runs each way, the safety scan on every listing, the connector, checking any skill on GitHub before you install it, and scanning your own public repositories. Teams pay $29 a month to scan private repositories on every pull request.

Who owns the skills?

Their authors do. We list each skill with a link to its source repository and only show a skill's full text when its license allows it.

How do I install a skill?

Every listing has a one-line install command that copies the skill folder into your project's.claude/skills directory.
