What problem does it solve? Reviewing RFCs, ADRs, and architecture proposals for TypeScript/Node backends often produces generic feedback that misses the real risks. This Skill performs a disciplined, read-only design review that starts from architecture, activates only the seams the design actually touches, and separates true flaws from deliberate trade-offs and missing proof. ## Core Features & Use Cases - Architecture-first review: Evaluates ownership boundaries, dependency direction, composition root, config and error boundaries, and module publication surfaces before anything else. - Seam-activated depth: Pulls in contract, Fastify runtime, Prisma/PostgreSQL, Redis, reliability, security, performance, or test-proof analysis only when the design genuinely crosses those seams. - Calibrated findings: Classifies every point as a finding, trade-off, missing proof, or acceptable assumption, with explicit severity, confidence, and the smallest useful correction. - Use Case: Given an ADR proposing a new caching layer with Redis, the review identifies whether Redis acts as cache, lock, or queue, challenges replay and TTL semantics, and states exactly what proof is still missing before the design is ready. ## Quick Start Ask the AI to review the attached backend design doc or ADR using the technical-design-review skill and report material findings, trade-offs, and missing proof.
