[EXTERNAL_DOWNLOADS]: The skill provides implementation patterns that rely on standard, well-known Node.js packages for real-time networking and data management.
Referenced packages: ws, jsonwebtoken, express, socket.io, @socket.io/redis-adapter, redis, and zod.
[INDIRECT_PROMPT_INJECTION]: The skill defines an architecture for processing untrusted data from external sources (WebSocket clients).
Ingestion points: Logic for handling incoming data in SKILL.md and references/advanced.md via the ws.on('message') event.
Capability inventory: The skill demonstrates broadcasting received messages to other connected clients and managing room-based state.
