What it does

This skill teaches an AI agent how to build other skills, which are reusable instruction folders that tell an agent how to handle a task. Once installed, the agent walks you through drafting a skill, writing test prompts, running them, grading the results, and improving the skill based on feedback. It also includes local scripts that generate a browser-based review page, summarize benchmark statistics across runs, and help tune a skill's description so it triggers at the right times.

Great for

  • Developers who want to package a repeated workflow into a reusable skill
  • Teams that want measurable evidence on whether a skill actually improves agent output
  • People iterating on an existing skill's wording or trigger description

Skip it if

  • Casual users who only want to use existing skills; this is for authoring them (the scripts run local evaluations that can take time and cost model usage)
  • Anyone running it on untrusted skill folders, since the bundled scripts execute code on your machine

Try asking

  • “Create a new skill that formats my weekly status reports in our team's style”
  • “Run evals on my invoice-extraction skill and show me the results in a review page”
  • “Benchmark this skill across several runs and report the variance”
  • “Optimize the description of my code-review skill so it triggers more accurately”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Review the scripts before running them on a skill you did not write, since they execute locally
  • Start with a few test prompts before scaling up to a larger eval set
  • Ask for a plain-language explanation if the eval terms like assertion or benchmark are unfamiliar
