Use when implementing RL algorithms, training agents with rewards, or aligning LLMs with human feedback - covers policy gradients, PPO, Q-learning, RLHF, and GRPOUse when ", " mentioned.
Invisible Chrome automation for web scraping via CDP. Use when WebFetch fails or gets blocked (403, 429, Cloudflare, bot protection, JS-rendered pages). Launches your real Chrome install completely hidden, sends commands via Chrome DevTools Protocol. Sites see a normal browser with real extensions - no detectable automation.

Generate Go repository port interfaces and implementations following GO modular architechture conventions (Gorm, PingoDB, OTEL tracing, Fx DI, ports architecture). Use when creating data access layers for entities in internal/modules/<module>/ including CRUD operations (Create, FindAll, FindByID, Update, Delete), custom queries, pagination, or transactions.
Build Model Context Protocol (MCP) servers on Cloudflare Workers - the only platform with official remote MCP support. TypeScript-based with OAuth, Durable Objects, and WebSocket hibernation.
