SKILL.md

Build stateful AI agents on Cloudflare Workers with WebSockets, persistent state, scheduling, and multi-agent coordination.

WebSocket-based real-time communication with automatic state synchronization across clients and devices; resumable streaming persists across disconnects and page refreshes

Built-in SQLite storage (up to 1GB per agent), task scheduling with cron expressions, and Durable Objects for globally unique, persistent agent instances

Multi-agent coordination via routeAgentRequest(), workflow triggering, browser automation, and RAG support with Vectorize

Integrates with Vercel AI SDK for automatic streaming or Workers AI for cost-effective inference; prevents 23 documented configuration and runtime errors including idFromName() gotchas and WebSocket payload limits
