What problem does it solve? Design documents often hide scaling issues, single points of failure, and architectural impossibilities that only surface in production. This Skill conducts a formal Senior Staff Engineer-style review to expose those risks before implementation begins. ## Core Features & Use Cases - Bottleneck Identification: Analyzes proposals for hidden scaling issues, SPOFs, and infeasible implementation details under Google-scale constraints like tail latency, CAP tradeoffs, and resource efficiency. - Structured Risk Output: Produces a risk assessment table with severity and category ratings, plus a required revisions section explaining why each issue fails at scale and suggesting alternatives. - Socratic Review Style: Uses probing questions (e.g., "What happens when the daemon restarts mid-operation?") to guide authors toward their own realizations rather than lecturing. - Use Case: Before approving a new distributed caching service proposal, run this review to surface backpressure propagation gaps and p99 latency risks the author overlooked. ## Quick Start Review this design document for scaling bottlenecks, single points of failure, and architectural risks, and present the findings as a risk assessment table with required revisions.
