Skill Creator

If you're building or optimizing Claude skills, this is your meta-tool. It walks you through the whole structure: frontmatter metadata, the 150-line rule for SKILL.md files, when to bundle scripts versus references, and how progressive disclosure keeps context lean. The guidance is opinionated about combining related topics (it suggests merging cloudflare-* skills into a single devops skill) and strict about descriptions staying under 200 characters so auto-activation actually works. What's useful here is the practical stuff: script environment variable precedence order, the reminder to write tests, and the emphasis on teaching Claude how to do tasks rather than documenting what tools are. It's basically the style guide and architectural decisions document rolled into one.

About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

IMPORTANT:

Skills are not documentation, they are practical instructions for Claude Code to use the tools, packages, plugins or APIs to achieve the tasks.
Each skill teaches Claude how to perform a specific development task, not what a tool does.
Claude Code can activate multiple skills automatically to achieve the user's request.

What Skills Provide

Specialized workflows - Multi-step procedures for specific domains
Tool integrations - Instructions for working with specific file formats or APIs
Domain expertise - Company-specific knowledge, schemas, business logic
Bundled resources - Scripts, references, and assets for complex and repetitive tasks
