SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and assets (resource) components.

What problem does it solve?

This Skill helps you design new Claude Code skills or iteratively improve existing ones by running structured trigger evaluations and using the results to refine the skill description for better accuracy.

Core Features & Use Cases

  • Skill drafting and iteration: Convert your desired workflow into a solid SKILL.md draft, then refine it based on evaluation outcomes.
  • Trigger evaluation loop: Generate a test set of real user queries, run both with-skill and without-skill baselines, and measure whether the skill triggers when it should.
  • Quantitative + qualitative review: Produce a benchmark summary and a review UI so you can inspect outputs and performance patterns before updating the skill.
  • Description optimization: Improve triggering accuracy by testing alternative descriptions and selecting a best-performing one.
  • Process guidance for edge cases: Ask the right questions up front to capture input/output formats, success criteria, and dependencies.

Quick Start

Use the skill to create a new skill by telling it what you want your skill to do and how you want users to recognize when it should trigger.

FAQPage Schema
How do I improve Claude Code skill triggering accuracy?

Improve Claude Code skill triggering accuracy by running an eval-driven loop that generates realistic test queries, executes with-skill and without-skill baselines, and uses automated benchmarking to iteratively refine the SKILL.md description.

What is an eval-driven loop for prompt engineering?

An eval-driven loop for prompt engineering is a structured iterative process where you create test cases, run benchmark evaluations against baselines, and select improved descriptions while avoiding overfitting to narrow examples.

How do I create a new Claude Code skill from scratch?

Create a new Claude Code skill from scratch by defining your desired workflow, drafting the SKILL.md instructions, generating trigger evals, and refining the description based on quantitative benchmark reviews.

Can I refactor an existing Claude Code skill description?

You can refactor an existing Claude Code skill description by running trigger evaluations, inspecting performance patterns in a review UI, and testing alternative descriptions to select the best-performing one without overfitting.

Why does my Claude Code skill trigger when it should not?

Your Claude Code skill may trigger incorrectly due to an overly broad description, which you can fix by generating a test set of real user queries and running automated benchmarks to isolate and optimize the triggering behavior.
