Excellent WebSocket skill with comprehensive coverage of real-time communication systems. The description clearly defines when to invoke (bidirectional messaging, scaling, presence tracking), making it actionable for a CLI agent. Strong task knowledge evidenced by detailed workflow, constraints, and reference architecture covering protocol details, scaling patterns, and security. Well-structured with SKILL.md providing concise overview and delegating deep technical details to five focused reference files. Novelty is good but not exceptional - while WebSocket scaling and Redis pub/sub require specialized knowledge, basic WebSocket implementations are increasingly common. The skill's value shines in complex scenarios (millions of concurrent connections, sub-10ms latency, horizontal scaling) where a generic CLI agent would struggle with architectural decisions around sticky sessions, backpressure, and clustering strategies.
