SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Skill creation and iteration is slow and guessy: you need a clear way to draft a new skill, test it against realistic prompts, measure trigger accuracy and performance, and then improve the instructions based on evidence.

Core Features & Use Cases

  • Draft from scratch or iterate on an existing skill: guides the user through producing a strong SKILL.md, including trigger description quality.
  • Run evals and compare with baselines: evaluates “with-skill” versus “without-skill” behavior across a test set.
  • Quantitative benchmarking with variance: aggregates results into pass-rate/time/token summaries for analysis.
  • Reviewer workflow for qualitative feedback: launches a viewer so you can inspect outputs and add structured feedback.
  • Description optimization: generates and tests candidate trigger descriptions to improve triggering accuracy.

Quick Start

Use skill-creator when you want to turn an idea into a new Claude Code skill or to improve an existing one by running a small eval set, reviewing results, and iterating until triggering and outcomes are reliable.

Frequently Asked Questions about skill-creator

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

FAQPage Schema
How do I create and benchmark Claude Code skills?▼

To create and benchmark Claude Code skills, you draft a SKILL.md, build test prompts, and run structured evaluations comparing with-skill versus without-skill behavior to measure performance.

What is the best way to improve trigger accuracy for Claude skills?▼

Improving trigger accuracy requires description optimization, which generates and tests candidate trigger descriptions against a test set to tune the skill description for reliable triggering.

How do I evaluate the performance of a Claude Code skill?▼

Evaluating a Claude Code skill involves running evals, grading outputs, and aggregating results into pass-rate, time, and token summaries with variance for quantitative benchmarking analysis.

Can I iterate on an existing skill using structured evaluations?▼

Yes, you can iterate on an existing skill by running an evidence-driven workflow that executes evals, launches a viewer for qualitative feedback, and loops instruction refinement until outcomes are reliable.

What is the process for refining skill instructions based on evidence?▼

Refining skill instructions based on evidence involves executing evaluations, grading the results, reviewing outputs via a viewer, and looping iterations using provided scripts to guide improvements.
