Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
artifacts-builder
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
backend-debugging
Systematic debugging for Encore.ts backend incidents using diagnostic scripts, database queries, and structured logging. Use when backend tests fail, services crash, or async flows stall.
backend-development
Integration-first development patterns for Encore.ts backend services. Focuses on importing subscriptions, polling async flows, verifying database state, and keeping diagnostic tooling close at hand.
before-task
Comprehensive discovery before starting any spec or major task. Searches Graphiti, recommends vibe/MCPs, surfaces patterns.
