Agent Skills

Free AI agent skills from GitHub, tested by a small, cheap model (Haiku). Further right means Haiku used it right more often.

How a skill is tested

A skill is a file that teaches an AI coding agent how to do one job. We test each one with a small, cheap model (Haiku), because if a small model gets it right, a big one will too.

  1. Picked right. Haiku sees the list of skills, like a real agent does, and gets 3 requests: 2 where this skill should be used and 1 that only sounds similar. It scores a point for each request it sends the right way.
  2. Followed right. Haiku reads the whole skill and a real request, then says its first step. A second Haiku call checks that step against the one the skill asks for.

Score: 1 point per request picked right (3) plus 2 points for following right, out of 5, shown out of 100. Further right is better. Green is 80 and up, amber 50 to 79, red below 50. Pick a kind of skill to see them as a leaderboard, best first. Haiku only sees skills from the same repo when it picks, as if you had installed that one collection. The test questions were written from each skill's own text by a stronger model, so a skill is never graded on something it does not claim to do. Last run: claude-haiku-4-5-20251001, 2026-10-28.
