Runs a structured failure-mode analysis on a proposed system architecture, ranking the top 5 risks by likelihood times impact with a one-sentence mitigation for each. Use it before finalizing any design to surface issues most likely to cause outages or missed deadlines.
Run a pre-mortem on this proposed architecture. Assume it is 12 months from now and this system has failed in production in a significant way. What are the most likely causes? Cover: data loss scenarios, cascading failure paths, performance cliffs that only appear at scale, operational complexity that overwhelms the team, and failure modes that only surface under specific conditions (high concurrency, partial network failures, specific data shapes).
Rank by likelihood × impact. Give me the top 5 only, with a one-sentence mitigation for each.
Proposed design: [describe the architecture]
