Core Features & Use Cases

  • Structured workflow for capturing intent, drafting SKILL.md frontmatter, and outlining instructions.
  • Built-in guidance for running evaluations, collecting feedback, and iterating to improve triggering accuracy.
  • Support for organizing iterative Skill development, documentation, and versioned improvements across projects.

Quick Start

Draft a new skill by capturing intent, writing SKILL.md with frontmatter, and running evaluations to collect feedback and iterate.

Frequently Asked Questions about skill-creator

FAQPage Schema
How do I create and iterate on Claude skills from scratch?▼

Skill creation involves drafting a SKILL.md file with structured frontmatter, writing instructions, and running evaluations to collect feedback and iterate on triggering accuracy.

What is a SKILL.md frontmatter and when do I need it for skill development?▼

SKILL.md frontmatter is a required structured metadata block containing the skill name and description. It is needed to enable accurate triggering and end-to-end skill creation.

How do I structure tests and run evals to benchmark Claude skill performance?▼

Structure tests by organizing optional folders for scripts and references, then run evaluations to benchmark performance, collect feedback, and iterate on trigger descriptions across projects.

Does skill creation require external dependencies or specific environment setup?▼

Skill creation requires no external dependencies. It needs a structured SKILL.md file and optionally supports folders for scripts, references, and assets to facilitate the iterative workflow.

What's the best way to optimize trigger descriptions for Claude skills?▼

Optimize trigger descriptions by running evaluations, collecting feedback through structured tests, and iterating on the SKILL.md frontmatter to improve benchmarking and triggering accuracy.

Can I edit existing skills instead of starting new skill creation from scratch?▼

Editing existing skills is supported by refining the SKILL.md frontmatter, updating instructions, and running evaluations to iterate based on feedback without needing to start from scratch.
