SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Skill Creator helps teams design, test, and iteratively improve Claude Skills with structured evals, benchmarks, and description optimization.

Core Features & Use Cases

  • Create new skills from templates
  • Iterate on Skill design via evals, benchmarks, and feedback
  • Improve skill descriptions for triggering accuracy
  • Analyze results and propose improvements to scripts, references, and assets
  • Use cases: building a new skill for a domain, refining an existing skill, benchmarking multiple versions

Quick Start

Draft your SKILL.md, run an eval loop with representative prompts, review results, and iterate on the description and implementation.

Frequently Asked Questions about skill-creator

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

FAQPage Schema
How do I evaluate and benchmark Claude skills for better triggering?

Evaluate Claude skills by running disciplined eval loops with representative prompts, benchmarking multiple versions, and refining descriptions for accurate triggering. Analyze the results to propose improvements to scripts, references, and assets.

What is the best way to iterate on AI skill descriptions?

Iterate on AI skill descriptions by running structured evaluation loops, reviewing benchmark results, and optimizing the text for better triggering accuracy. This feedback loop ensures reproducible skill improvements across the lifecycle.

How do I create a new skill from a template?

Create a new skill by drafting a SKILL.md file from a template, running an evaluation loop with representative prompts, and reviewing the results. Iterate on the implementation and description based on this structured feedback.

Does the Skill Creator workflow require pyyaml?

Yes, the Skill Creator workflow requires the pyyaml dependency to parse configuration files and manage skill metadata. This allows the evaluation scripts to process the structured definitions during benchmarking.

Why does my AI skill fail to trigger correctly in production?

AI skills fail to trigger correctly when their descriptions lack the necessary keywords or context for accurate matching. Resolve this by running description optimization evals and refining the text based on benchmark performance.

Can I use this approach to benchmark multiple versions of a skill?

Yes, you can benchmark multiple versions of a skill by running comparative evals with representative prompts. The workflow supports experiment tracking and feedback loops to identify the best performing implementation.
