Based on SOC occupation classification
Database engineering standards for PostgreSQL, MySQL, MongoDB, Supabase and Firebase/Firestore — schema/index design, security, and the per-engine gotchas an agent gets wrong. Loaded on top of backend-craft when a ticket touches the database. Use when designing schema, queries, migrations or data-access.
Next.js App Router full-stack standards — server/client boundaries, the four caching layers, server-action security, route handlers, rendering/streaming, metadata, middleware limits, and Next-specific testing. Loaded on top of react-craft (and alongside backend-craft for server code) when the ticket's stack is Next.js. Use when building any Next.js route, action, or API surface.
Headless QA tooling for driving real test tools from the CLI — Postman/Newman (functional + contract), OWASP ZAP + nuclei (security/DAST, the agent-drivable substitute for Burp), and k6/JMeter/autocannon (load). Use when running a comprehensive QA/security/load sweep against a running app.
Full delivery pipeline — takes a feature/project request, plans it into Jira-like markdown tickets, builds each ticket with specialized developer agents, then runs QA, security and code-audit agents, loops a debugger agent over findings until clean, and closes with a final report. Use when the user asks to build a feature or project end-to-end, or invokes /ship.
Express.js (Node) engineering standards — layering, async error handling (Express 4 vs 5), boundary validation, security middleware, graceful shutdown, and testing. Loaded on top of backend-craft when the ticket's stack is Express. Use when building Express APIs.
NestJS engineering standards — feature-module architecture, DI discipline, DTO validation, the guard/interceptor/pipe/filter split, config, TypeORM/Prisma, and testing. Loaded on top of backend-craft when the ticket's stack is NestJS. Use when building NestJS APIs.

A good test reads like a specification of behavior and survives refactoring: it exercises a public seam (API endpoint, exported function/hook, component behavior, CLI) and asserts observable outcomes — not internals.
expect(result).toBeDefined() as the only assertion).
