SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, jinja2, xlsx, lsof, and includes scripts (resource) and assets (resource) and references (resource) components.

What problem does it solve?

This Skill helps you design new Claude Code skills, improve existing ones, and prove whether changes actually improve performance instead of relying on intuition alone.

Core Features & Use Cases

  • Skill creation & iteration: Turn your desired workflow into a working skill draft, then refine it through repeated test-and-feedback cycles.
  • Automated trigger evaluation: Generate test queries and optimize the SKILL.md description so Claude calls the skill at the right times (and avoids irrelevant triggers).
  • Benchmarking with comparison: Run the skill versus a baseline (with/without skill), grade outcomes with explicit expectations, and summarize results with pass rate and variance.

Quick Start

Use the anthropic-skill-creator skill when you want to create or refine a Claude Code skill; tell it what you want the skill to do, when it should trigger, and what success looks like, then approve the proposed test set and evaluation plan.

Frequently Asked Questions about anthropic-skill-creator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I evaluate and benchmark Claude Code skills against a baseline?

You can evaluate Claude Code skills by running structured evaluation loops that generate test prompts, execute skill versus baseline runs, grade outcomes against explicit expectations, and aggregate benchmark statistics like pass rate and variance.

How do I optimize skill triggering so Claude Code calls the right skill at the right time?

Optimize skill triggering by generating test queries and iteratively refining the SKILL.md description, which improves trigger correctness so Claude activates the skill in relevant contexts and avoids irrelevant calls.

What is the process for iterative improvement of skill instructions?

Iterative improvement of skill instructions involves drafting new skill instructions, running evaluation prompts across test suites, and refining both behavior and triggering accuracy through repeated test-and-feedback cycles.

Can I automate grading for skill evaluation test suites?

Yes, you can automate grading by applying grader automation within evaluation loops, which grades outcomes with explicit evidence and aggregates pass rate statistics to measure performance comparisons between skill versions.

Do I need to prepare test prompts before creating a new Claude Code skill?

You define what you want the skill to do, when it should trigger, and what success looks like, then approve the proposed test set and evaluation plan before the skill draft is generated and evaluated.

What is the best way to prove a skill change actually improves performance?

The best way to prove a skill change improves performance is to run benchmarking with comparison, executing the skill versus a baseline with and without the skill, grading outcomes with explicit expectations, and summarizing pass rate and variance.
