Install-tested in 5 real agents · last run 2026-11-14

Find agent skills that actually work in your agent.

We don't copy READMEs. We actually install each add-on in Claude Code, Codex, Grok Build, Cursor and Pi (wherever it's supported), re-run it nightly, and tell you what passed, what broke, and why.

I use:

How we test (yes, actually)

  1. 1

    We pull the add-ons

    From public lists: the official Claude Code, Codex and Grok Build marketplaces, the MCP reference servers and npm. 428 so far.

  2. 2

    We run the real install, nightly

    In each agent's real CLI, in a throwaway sandbox with no accounts or keys. Then we check the agent actually loaded it.

  3. 3

    We publish pass/fail + why

    Every result gets a date and a log excerpt. Failures stay up, not swept under the rug.

Why care? You don't burn an hour on an install that was never going to work. How we test, limits included → · Today's daily report →

Honest labels: Tested ✓ our harness installed and loaded it in that agent. ✕ Failed it didn't, and the log says why. ✓ Verified from docs an official source publishes the install method. Not yet tested no docs and no test yet.
