SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill unit provides a structured framework for designing, testing, and iterating Claude skills end-to-end, including drafting SKILL.md, running evals, benchmarking, and describing improvements.

Core Features & Use Cases

  • End-to-end skill creation workflow: from interview to final SKILL.md and optional resources.
  • Built-in evaluation loop: run prompts, collect results, and automatically propose improvements.
  • Benchmark-ready: produce JSON benchmark data and human-readable reports to compare iterations.
  • Documentation & packaging tools: scripts to validate, package, and publish skills.

Quick Start

Use this workflow to create or improve a skill: draft the SKILL.md, run the evaluation loop on a sample eval set, review results, and iterate until you reach a stable, high-quality skill description.

FAQPage Schema
How do I create and iterate on Claude skills end-to-end?

To create Claude skills, you draft a SKILL.md file, run evaluation loops on sample sets, review benchmark results, and iterate until reaching a stable, production-ready skill description.

What is the best way to benchmark and evaluate skill triggering accuracy?

Benchmarking skill triggering accuracy involves running prompts through an evaluation loop, collecting JSON benchmark data, and reviewing human-readable reports to compare iterations and propose improvements.

Can I package and publish skills with bundled scripts and references?

Yes, skills can be packaged and published by bundling optional scripts, references, and assets for on-demand execution and verification to ensure reproducible outputs.

How does the skill creation workflow handle user interviews and drafting?

The skill creation workflow collects user interviews, drafts the initial SKILL.md file, and orchestrates iterative evaluations to produce a polished, production-ready skill description.

Do I need prior benchmark data to start refining an existing skill?

No prior benchmark data is required; the workflow generates JSON benchmark data and human-readable reports by running evaluation loops on a sample eval set to measure and compare iterations.
