Living open-source map

Compare agent skill repos, MCP servers, coding agents, and workflow libraries.

Use the directory to study trusted public projects before you install, fork, or adapt a workflow. It is built to keep moving as repos appear, change, or go stale.

Marketplace model

Pick skills with enough context to trust them.

Good AI workflows need more than a clever prompt. A useful listing should show the source, contents, use case, setup path, and a simple way to confirm it worked.

When to use it: the job, trigger, or situation the skill is built for.

What you get: SKILL.md files, scripts, prompts, examples, or repo links.

Why to trust it: creator, source, license, maintenance status, price, and review notes.

How to check it: the test or review step that proves the workflow worked.

How it should work

A simple path from browsing to using a skill

Start with the job you want your agent to handle, then pick the skill type that gets you there fastest.

01

Choose what you need

Install a ready skill, study a public repo, or buy a creator pack without guessing which kind of listing you are looking at.

02

Check the fit

See who made it, what is inside, what outcome it helps with, and what to review before you trust it.

03

Put it to work

Copy the skill, adapt the repo, or unlock the paid pack, then run the included verification step on a real task.

Creator submissions

Package your best workflow so other builders can use it.

If you have a repeatable workflow for marketing, launch, research, sales, QA, content, or operations, turn it into a skill builders can install, test, and run with their AI agent.

See Build Lean SaaS Pro

Submission checklist

  • • A readable SKILL.md or repo bundle
  • • A clear buyer and use case
  • • Install, import, or review instructions
  • • Trust notes: author, license, maintenance, and price
