Usage Examples

Dataform Development

User: I need to create a new customer metrics table in Dataform
Claude: /dataform-new-table
[Guides through TDD workflow: write tests first, then implementation]

3D Printing

Claude: /stl-circle-jig
[Generates STL file with specified dimensions, ready for 3D printing]

Plugin Development

This repository follows the Claude Code plugin development best practices:

• Marketplace structure: Root .claude-plugin/marketplace.json defines available plugins
• Plugin organization: Each plugin in its own directory with .claude-plugin/plugin.json
• Skills: Reusable process documentation that enforces discipline
• Commands: Quick-access workflows for common tasks
