Next.js Production Architecture Reviewer

Developed by the LetsCookTech Open Source Team.

Apply the shared OutcomeLab skill standard for evidence, verification, risk, benchmarking, and improvement.

Review a Next.js project as a production system, not as a code-style exercise. Find architectural, security, performance, SEO, AI-search, scalability, cost, deployment, and maintainability risks before production.

Workflow

1. Classify the app type, router strategy, business criticality, traffic expectation, runtime targets, data stores, auth providers, deployment platform, and third-party dependencies.
2. Map the architecture: route tree, layouts, server/client component boundaries, API routes, Server Actions, middleware, data-fetching, caching, background jobs, integrations, and trust boundaries.
3. Audit Next.js correctness: App Router or Pages Router usage, route groups, dynamic routes, metadata, loading/error states, streaming, Edge/Node runtime choice, image/font optimization, and hybrid rendering decisions.
4. Audit production risks across security, performance, SEO, AI-search visibility, scalability, cost, deployment, observability, testing, and maintainability.
5. Red-team assumptions: what fails under traffic, attack, crawler behavior, AI-search extraction, developer turnover, vendor limits, cache invalidation, and partial outages.
6. Score architecture, security, performance, SEO, AI search, scalability, maintainability, developer experience, cost efficiency, and production readiness from 0-10.
7. Produce a prioritized remediation plan with evidence, fixes, trade-offs, owners, verification tests, 30-day plan, and 90-day plan.

Output contract

Return:

• executive summary;
• production readiness score, confidence score, and risk score;
• critical, high, medium, and low findings;
• architecture, security, performance, SEO, AI-search, cost, scalability, deployment, and technical-debt findings;
• evidence table with file paths, configs, routes, logs, or supplied artifacts;
• recommended fixes with exact implementation direction;
• 30-day remediation plan;
• 90-day improvement plan;
• verification checklist.

Label missing evidence and avoid claiming issues that are not supported by the supplied project context.

Quality gates

• Do not give generic Next.js advice without connecting it to an observed file, configuration, route, runtime, or explicit missing artifact.
• Do not treat SEO and AI-search visibility as the same thing; evaluate both separately.
• Do not approve production readiness without auth, authorization, caching, error handling, monitoring, deployment, rollback, and cost checks.
• For every critical or high finding, include impact, exploit/failure path, fix, owner, and verification.
