2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 13 stars13 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Skill Creator

Create effective Agent Skills using progressive disclosure. For choosing validation and distribution tooling around skills, use ecosystem-guide.

When to Create a Skill

Create a skill when you notice:

  • Repeating context across conversations
  • Domain expertise needed repeatedly
  • Project-specific knowledge the agent should know automatically

Progressive Disclosure

Skills load in 3 levels:

  1. Metadata (~27 tokens optimal, ~100 max) - YAML frontmatter for triggering
  2. Instructions (<50 lines recommended, 500 max) - SKILL.md body with core patterns
  3. Resources (unlimited) - references/ scripts/ assets/ loaded on demand

Key: Keep Levels 1 & 2 lean. Move details to Level 3. Use npx claude-skills-cli validate to check budgets.
