Everything Engineering Toolkit

Use this when the task spans multiple engineering concerns and needs routing.

First Pass

1. Identify the primary domain: frontend, backend, data, infra, security, docs, tests, release, or automation.
2. Read local project instructions and the smallest relevant code area.
3. Choose the existing project pattern over a new one.
4. Define the verification surface: unit, integration, e2e, lint/typecheck, browser, logs, or manual artifact inspection.

Domain Playbooks

• Repo onboarding: map stack, package manager, entrypoints, test commands, env requirements, and risky shared modules.
• Architecture: capture current boundaries, propose the smallest change, write an ADR only if the decision will matter later.
• API/backend: validate contracts, errors, auth, persistence, idempotency, and observability.
• Frontend: verify responsive layout, interaction states, accessibility, and real browser rendering.
• Testing: add focused coverage at the lowest level that proves behavior; widen when contracts or workflows change.
• Security: look for authz bypass, injection, secret leakage, unsafe deserialization, SSRF, path traversal, and supply-chain risk.
• Deployment: check env vars, migrations, build output, rollback path, and runtime assumptions.
• Documentation: write only docs that help future operation, onboarding, or user-facing behavior.

Output Standard

For implementation: concise summary, files changed, checks run, remaining risks.

For analysis/review: findings first, severity, file references, reproduction or reasoning, and recommended fix.
