SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml.

What problem does it solve?

The Skill Creator helps you design, test, and continuously improve Claude skills—bridging the gap between idea and reliable, measurable performance.

Core Features & Use Cases

  • Draft, organize, and iterate on SKILL.md content.
  • Run end-to-end eval loops with automated prompts, benchmarks, and viewer-backed feedback.
  • Bundle optional resources (scripts, references, assets) and validate safety and structure.

Quick Start

Create a new skill by authoring SKILL.md, then run the full eval-improve loop to test, review, and refine the skill.

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 test a Claude skill from scratch?▼

To create a Claude skill, draft your SKILL.md content and then run an end-to-end eval loop to test, benchmark, and refine the skill's performance using automated prompts and feedback.

What is the best way to iterate on skill descriptions for reliable performance?▼

Iterating on skill descriptions requires running continuous eval loops with automated benchmarks and viewer-backed feedback to measure performance, which guides the refinement of your SKILL.md content.

Can I bundle external scripts and references when building Claude skills?▼

Yes, you can bundle optional resources like scripts, references, and assets into your Claude skill, while the creation workflow validates the overall structure and safety of these components.

Do I need pyyaml installed to use the Skill Creator workflow?▼

Yes, pyyaml is a required dependency for the Skill Creator, as it is needed to process and validate the structured configuration files used throughout the skill creation and benchmarking workflow.

Why does my Claude skill fail safety and structure validation?▼

Safety and structure validation fails occur when the SKILL.md content or bundled resources do not meet the required benchmarks, requiring you to run the eval loop and refine the skill design.
