SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Automates the end-to-end workflow for creating, testing, and iterating Claude skills. It guides you from drafting a SKILL.md entry through structured evals, benchmarking, and iterative improvements, enabling rapid skill maturation and reliable triggering.

Core Features & Use Cases

  • Capture Intent and Write SKILL.md: Define the skill's identity, purpose, and usage guidance to set clear expectations for triggering.
  • Run Evals and Benchmarks: Execute structured prompts, collect metrics, and compare with baselines to quantify value.
  • Iterate and Improve: Use evaluation history to refine descriptions, add tests, and streamline the skill for broader applicability.
  • History and Collaboration: Track iterations, store results, and reuse scripts for consistency across cycles.

Quick Start

Draft a skill, write a few test prompts, run the eval loop, and iterate until results are stable and triggering is reliable.

FAQPage Schema
How do I automate Claude skill creation and testing?

You can automate Claude skill creation by drafting a SKILL.md file, running structured evals, and iterating on descriptions. This workflow manages the end-to-end process from initial drafting to reliable triggering.

What is a structured eval loop for prompt engineering?

A structured eval loop executes test prompts, collects metrics, and benchmarks results against baselines. This process quantifies the value and triggering accuracy of your skill iterations.

Does skill-creator require pyyaml to run evaluation scripts?

Yes, skill-creator requires the pyyaml dependency to run its scripts. You need this Python package installed to manage the structured configuration files used during skill creation.

How do I improve Claude skill triggering accuracy?

You improve triggering accuracy by using evaluation history to iteratively refine SKILL.md descriptions. Running benchmarks and adding tests ensures the skill triggers reliably across broader applicability.

What is the best way to benchmark Claude skills?

The best way to benchmark Claude skills is running structured prompts and comparing the collected metrics with baselines. This quantifies value and tracks iteration history for consistency across cycles.

Why does my Claude skill trigger unreliably?

Your skill triggers unreliably when its description lacks clear identity and usage guidance. Iterating on the SKILL.md entry and evaluating test history refines the skill to maximize triggering reliability.
