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.
