SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Helps authors and teams reliably create, test, and iterate Claude Code skills by providing a repeatable workflow for drafting SKILL.md files, generating test prompts, running with-skill vs baseline evaluations, and packaging deliverables. It reduces manual validation work, prevents regressions, and surfaces objective metrics so improvements are evidence-driven.

Core Features & Use Cases

  • Guided Skill Authoring: Prompts and templates to capture intent, trigger conditions, output formats, and examples for a new or existing skill.
  • Eval & Benchmarking Workflow: Create eval sets, spawn parallel runs, capture timing/tokens, grade expectations, and aggregate benchmark summaries.
  • Iteration Loop: Draft descriptions, run train/test splits, automatically propose improved descriptions, and re-evaluate until results stabilize.
  • Packaging & Presentation: Tools to package a validated skill into a distributable .skill file and generate human-facing review pages for qualitative feedback.
  • Use Case: Turn a rough idea ("convert invoices to CSV") into a production-ready skill with test cases, graders, benchmark reports, and a polished SKILL.md.

Quick Start

Ask the assistant to draft a SKILL.md for your intent, propose 2–3 realistic test prompts, and run the evaluation loop to generate initial benchmark results.

FAQPage Schema
How do I create and test a SKILL.md file for Claude Code?

To create and test a SKILL.md file, use a guided authoring workflow to draft the skill, generate test prompts, run with-skill vs baseline evaluations, and package the validated output into a distributable format.

What's the best way to benchmark Claude skills and prevent regressions?

Benchmarking Claude skills requires running parallel eval sets, capturing timing and token usage, grading expectations, and aggregating summaries to compare with-skill versus baseline performance for evidence-driven improvements.

How does trigger description optimization work for Claude.ai skills?

Trigger description optimization works by drafting descriptions, running train/test splits, automatically proposing improved descriptions via the Anthropic API, and re-evaluating until benchmark results stabilize.

Do I need the Anthropic API to optimize skill trigger descriptions?

The Anthropic API is an optional dependency for description optimization. You can still author SKILL.md files, run benchmarking workflows, and package skills using the core tooling without it.

Can I package a validated skill into a distributable format automatically?

You can package a validated skill automatically into a distributable .skill file and generate human-facing review pages to collect qualitative feedback after the evaluation loop stabilizes.

How do I structure YAML frontmatter and assets for a new Claude skill?

Structuring a new Claude skill requires YAML frontmatter with name and description fields, plus organized directories for scripts, references, and assets to satisfy automated trigger and benchmark tooling requirements.
