SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

The Skill Builder enables teams to create, modify, benchmark, and continuously improve Claude Code skills with a structured lifecycle.

Core Features & Use Cases

  • End-to-end skill lifecycle: capture intent, interview & research, write SKILL.md, test, evaluate, and improve.
  • Progressive disclosure: lean SKILL.md with rich references and optional bundled resources (scripts/references/assets) to handle complexity.
  • Benchmarking & evals: guided process to run trigger evaluations, compare outputs, and iterate toward better triggering.
  • Operator-style workflow: integrates with the Push description optimization and analysis references to refine skills over time.

Quick Start

Begin by outlining a new skill in SKILL.md and start the skill-builder loop to draft, test, and refine it.

Frequently Asked Questions about skill-builder

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

FAQPage Schema
How do I build and test Claude Code skills from scratch?

Progressive disclosure in skill-building involves writing a lean SKILL.md supported by rich references and bundled resources like scripts. This approach manages complexity by revealing detailed information only when needed during the workflow.

How do I evaluate and benchmark Claude Code skills?

You evaluate Claude Code skills by running trigger evaluations and comparing outputs using the provided tooling. This guided benchmarking process tracks performance and helps iterate toward better triggering and overall skill quality.

What is the best way to structure a SKILL.md file for complex workflows?

The best way to structure a SKILL.md file is using progressive disclosure with lean frontmatter and optional bundled resources. This keeps the core file lightweight while leveraging references and assets to handle workflow complexity.

Do I need Python dependencies to run skill evaluations and benchmarks?

Yes, you need Python dependencies including anthropic and pyyaml to run skill evaluations and benchmarks. These libraries enable the scripts to interface with Claude and parse configuration files during the testing loop.

Can I iteratively improve skill descriptions to optimize triggering?

Yes, you can iteratively improve skill descriptions to optimize triggering by applying an operator-style workflow. This integrates Push description optimization and analysis references to refine how skills activate over time.
