Deep expertise in E-commerce domain logic (Cart, Checkout, SKU). Trigger this when building shopping features on top of MVC or ADR.
Event modeling facilitation for discovering and designing event-sourced systems. Four phases: domain discovery, workflow design (9-step process), GWT scenario generation, and model validation. Activate when starting a new project, designing features, modeling domains, writing Given/When/Then scenarios, or discussing event sourcing and domain-driven design.
Master Node.js streams for memory-efficient processing of large datasets, real-time data handling, and building data pipelines
File-based routing conventions for Cloudwerk, a full-stack framework for Cloudflare Workers. Use when creating pages, API routes, layouts, middleware, or error boundaries. Triggers on tasks involving route files (page.tsx, route.ts, layout.tsx, middleware.ts, error.tsx, not-found.tsx), dynamic segments ([id], [...slug]), route groups ((group)), loaders, actions, or data loading patterns.
Java and Spring Boot expert including REST APIs, JPA, and microservices
Use for privacy preserving applications and ZK Solana programs. Prevents double spending using rent-free PDAs.
Check Apideck connector API coverage before building integrations. Use when determining which operations a connector supports, comparing connector capabilities, or diagnosing why an API call fails with a specific connector. Teaches agents to query the Connector API for real-time coverage data.
Build production database layers with SQLAlchemy ORM and PostgreSQL. This skill should be used when teaching students to define data models, manage sessions, perform CRUD operations, and connect to PostgreSQL/Neon databases.
