What problem does it solve? AI tools generate code faster than humans can verify it, shifting the engineering bottleneck from writing code to deciding whether to trust it. This Skill helps engineers act as gatekeepers who demand verifiable evidence before merging AI-generated changes, preventing architecture drift and hidden defects. ## Core Features & Use Cases - Trust Evidence Framework: Requires independently verifiable evidence (tests, architectural invariant checks, behavioral contracts) for every AI-generated change before approval. - Architecture Drift Defense: Enforces explicit architectural invariants to stop the compounding inconsistencies ("AI entropy") that accumulate when locally correct but globally inconsistent code is merged. - Gatekeeper Review Checklist: Provides MUST/SHOULD review criteria and anti-pattern guidance (blind trust, rubber-stamp review, experience bypass) for auditing AI output. - Use Case: A senior engineer reviewing a pull request containing AI-generated discount logic uses the checklist to probe edge cases (legacy customer tiers), demands a failing-test proof, and verifies the change against documented architectural invariants before signing off. ## Quick Start Ask the assistant to apply the judgment-and-trust checklist to review an AI-generated pull request and identify what trust evidence is missing before merge.
