GitHub has tens of thousands of SKILL.md files. Almost none have been run by anyone but their author. SkillProof installs them from their repo, triggers them, and runs them on a real task against a no-skill baseline. This MCP server puts those verdicts in your agent's hands.

> is there a tested skill for converting markdown to Confluence?

## Confluence — DIDN'T PASS — scored below the no-skill baseline
What our test found: Ran the bundled convert_markdown_to_wiki.py on a real sample doc: it silently
turns **bold** text into wiki _italic_ (a genuine regex bug), and leaves standard GitHub-style tables
completely unconverted, despite SKILL.md listing "tables" among the elements it handles.

That is the whole point. A directory that only lists winners tells you nothing.

Tools

Tool	What it answers
`find_skill`	"Is there a tested skill for X?" — ranked matches with verdict, score, test notes, install command
`check_skill`	"Someone recommended X — is it any good?" — the verdict for one skill by name, slug, or repo

Every answer carries one of three verdicts:

pass — installed, triggered, and beat the no-skill baseline on a real task.
setup — works, but needs a manual step first (the notes say which).
didn't pass — scored below the no-skill baseline: it either couldn't run, or left you worse off than not installing it.

If nothing has been tested for your job, the server says so instead of guessing. "Not tested" is a real answer.

Install

Claude Code:

claude mcp add skillproof -- npx -y skillproof-mcp

Or add it to your MCP config by hand:

{
  "mcpServers": {
    "skillproof": {
      "command": "npx",
      "args": ["-y", "skillproof-mcp"]
    }
  }
}

Works in any MCP client (Claude Code, Claude Desktop, Cursor, Windsurf, Zed). Node 18+. No API key, no account.

Where the data comes from

The server reads the live catalog at skillproof.dev/api/skills.json and caches it for 15 minutes. Nothing is bundled, so verdicts are never stale. The scoring rubric — install /5, triggering /5, output-vs-baseline /10, docs /5 — is published at skillproof.dev/methodology.

Catalog data is CC BY 4.0: use it, cite skillproof.dev.
