sse-resilience

Quick Review

Excellent skill addressing a real production challenge with SSE streams. Provides comprehensive implementation including Redis-backed registry, heartbeat monitoring, completion recovery, and background cleanup guardian. The code is production-ready with proper types, error handling, and client-side recovery logic. Structure is clear with well-organized sections. Novelty is high as this solves silent failure scenarios that would require significant token expenditure for a CLI agent to design from scratch. Minor deductions: the description could slightly emphasize the recovery endpoint mechanism, and the recovery endpoint code is shown in client usage but not fully implemented in the backend section. Overall, a highly practical skill that reduces complexity and cost for handling resilient SSE architectures.
