SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Skill-creator helps you reliably create and iterate on Claude skills by turning your goals into a drafted SKILL.md, generating realistic test prompts, running trigger/evaluation checks, and using results to refine the skill for better triggering accuracy and performance.

Core Features & Use Cases

  • Skill drafting and iteration: Converts a user’s intent into a working skill draft and iteratively improves it.
  • Evaluation workflow: Builds a test set, runs evaluations, and compares behavior against a baseline to quantify impact.
  • Benchmarking and review tooling: Produces review artifacts and benchmark summaries to support qualitative and quantitative decisions.
  • Description optimization: Improves the skill’s YAML frontmatter description to increase correct triggering and reduce false triggers.
  • Process guidance: Guides interviews, edge-case thinking, test coverage planning, and feedback-driven rewrites.

Quick Start

Use skill-creator when you want to build a new Claude skill for “processing browser-side PDFs” from scratch, then iteratively refine its description and eval results until it triggers at the right moments.

FAQPage Schema
How do I create and test a Claude Code skill from scratch?

To create and test a Claude Code skill, draft a SKILL.md file defining your intent, generate test prompts, and run trigger/evaluation loops. This iterative process refines the skill's triggering accuracy and task performance.

Why does my Claude skill trigger incorrectly or fail to activate?

Your Claude skill triggers incorrectly due to an unoptimized YAML frontmatter description. Improve triggering accuracy by running benchmark evaluations on should-trigger and should-not-trigger queries, then iteratively rewriting the description.

What is the best way to evaluate and benchmark Claude skills?

The best way to evaluate and benchmark Claude skills is to build a test set, run evaluations against a baseline, and use grader aggregation. This quantifies behavioral impact and produces review artifacts for qualitative decisions.

Do I need Claude to automate skill design and trigger optimization?

Yes, you need the Claude dependency to automate skill design and trigger optimization. It executes the root SKILL.md-based folder workflow, generates realistic test prompts, and performs the evaluation runs required for iterative revision.

Can I improve an existing Claude skill without rebuilding it entirely?

Yes, you can improve an existing Claude skill without a full rebuild. Apply targeted description optimization and run trigger/evaluation checks to refine the YAML frontmatter, increasing correct activation and reducing false triggers.
