The instructions your model reads when the skill loads.
This skill extends code-reviewer (the universal skill). Always apply the universal
skill's full checklist first, then apply the Node.js-specific rules in this file on top.
Composition order:
code-reviewer (universal pillars: correctness, security, performance, DRY, tests, docs)Run these commands before touching any code. Version determines which rules apply.
# Node.js runtime version
node --version
cat .nvmrc 2>/dev/null
cat .node-version 2>/dev/null
# Package manager and key dependencies
cat package.json | grep -E '"(node|engines|typescript|express|graphql|apollo-server|bullmq|bull|jsonwebtoken|zod|joi|helmet|express-rate-limit)"'
# TypeScript config
cat tsconfig.json 2>/dev/null | grep -E '"(strict|target|module|moduleResolution)"'
# Check if ESM or CJS
cat package.json | grep '"type"'
Report at the top of your review:
🔍 Environment: Node.js vX.Y | TypeScript X.Y | Express X.Y | ESM/CJS
Packages: [graphql, apollo-server, bullmq/bull, jsonwebtoken, zod/joi — versions]
Then apply the version-specific rules below that match.
