What problem does it solve? Design flaws discovered after code is written are expensive to fix. This Skill stress-tests a Tech-Lead design or implementation plan before any code is written, catching requirement gaps, architectural weaknesses, and contract risks while they are still cheap to correct. ## Core Features & Use Cases - Adversarial Plan Review: Sweeps eight attack lenses (requirements, architecture, contract, data, security, operability, cost, testability) against the plan and its business brief. - Machine-Readable Verdicts: Emits a structured PROCEED, REVISE, or BLOCK verdict with severity-ranked findings, confidence score, and audit ID that a workflow engine can gate on. - Bias Mitigation: Requires a steelman of the plan first, enforces reviewer-author heterogeneity, and filters hallucinated or unfalsifiable findings. - Use Case: Before fanning out an epic to per-component implementation tasks, run this Skill on the Tech-Lead design to decide whether the plan is safe to build, needs revision, or must be blocked. ## Quick Start Red-team this implementation plan against the attached epic brief and tell me whether it is safe to fan out to per-component work.
