MongoDB best practices including schema design, indexing, and query optimization.

Scaffold Next.js App Router routes for simple pages without forms or complex logic. Use when user needs "create a page", "add route", "add about/contact/terms page", "create API endpoint", "add layout", or mentions SSE/webhooks. Generates page, layout, loading, error, and not-found files with boilerplate. Best for static content, read-only pages, and API endpoints (REST, SSE, webhooks). Do NOT use for forms with validation (use worldcrafter-feature-builder), complete features with database (use worldcrafter-feature-builder), database-only changes (use worldcrafter-database-setup), or comprehensive testing (use worldcrafter-test-generator).

Automatically applies when working with database migrations. Ensures proper Alembic patterns, upgrade/downgrade scripts, data migrations, rollback safety, and migration testing.
