Go Package Skill Creator

Go Package Skill Creator

Generate skills that teach how to use specific Go packages.

Workflow

1. Gather information:

   • Package import path (e.g., github.com/lestrrat-go/jwx/v3)
   • Additional examples or use cases (optional)
   • Any specific aspects to emphasize (optional)

2. Fetch documentation:

   • Get package documentation from https://pkg.go.dev/<import-path>
   • Extract: package overview, main types, key functions, and code examples
   • If the package has multiple subpackages, fetch the most relevant ones

3. Analyze package complexity:

   • Simple (single purpose, <10 key functions): Focus on core usage pattern with 1-2 examples
   • Medium (multiple types, 10-30 functions): Include common patterns and error handling
   • Complex (framework-like, >30 functions): Split into sections, consider references/ for advanced topics

4. Derive skill identity:

   • Name: Use go- and the last segment of import path (e.g., jwx from github.com/lestrrat-go/jwx/v3)
     • If name is too generic (like http or json), prepend with package scope (e.g., go-fasthttp)
   • Description: Include:
     • What the package does (1 sentence)
     • Primary use cases (2-3 bullet points)
     • When to trigger: "Use when working with [domain], [specific task], or when the user mentions [package name]"

5. Create skill structure:

   <package-name>/
   ├── SKILL.md
   └── references/        (optional, only if complex)
       └── advanced.md
   

6. Write SKILL.md following the template in references/skill-template.md:

   • Keep under 500 lines if possible
   • Focus on practical patterns over API reference
   • Include runnable examples
   • For complex packages, move advanced topics to references/

7. Create the skill directory and files:

   • Use Write tool to create SKILL.md
   • Create any necessary reference files
   • No README.md or auxiliary documentation

8. Validate structure:

   • Confirm YAML frontmatter is valid
   • Check that description is comprehensive and includes triggers
   • Ensure examples are runnable
   • Verify references are properly linked if used

See references/skill-template.md for the standard structure and references/analysis-guide.md for determining appropriate detail level.
