Use when building Rust web services, REST APIs, or when working with Axum, Tower middleware, or async Rust backends.
Create Next.js Server Actions with enhanceAction, Zod validation, and service patterns. Use when implementing mutations, form submissions, or API operations that need authentication and validation. Invoke with /server-action-builder.
FastAPI Python backend in api/. Covers routes, models, Supabase integration, authentication, R2 storage, and Cloudflare Workers deployment. Port 9990 for local dev. OpenAPI docs at /docs.
Build complete features with Server Actions, forms, Zod validation, database CRUD operations, and comprehensive tests. Use when user requests "add a feature", "build a [feature]", "create [feature] with forms", or needs end-to-end implementation with validation and testing. Scaffolds pages, actions, schemas, loading/error states, and unit/integration/E2E tests. Supports multi-step wizards, image uploads, markdown editing, custom JSON attributes, and relationship management. Do NOT use for simple static pages (use worldcrafter-route-creator), database-only changes (use worldcrafter-database-setup), testing existing code (use worldcrafter-test-generator), or auth-only additions (use worldcrafter-auth-guard).

Rust Axum API with Diesel ORM and DDD architecture.
Génère des Next.js Server Actions comme couche d'orchestration mince entre frontend et backend NestJS. À utiliser lors de la création d'actions, mutations, ou quand l'utilisateur mentionne "server action", "mutation", "form action", "useTransition", "revalidatePath".
This skill should be used when the user asks to "create a Next.js page", "add a route", "create a layout", "implement server components", "add client components", "create API routes", "implement server actions", "add loading states", "handle errors in Next.js", "create dynamic routes", "implement parallel routes", "add intercepting routes", or mentions Next.js App Router, React Server Components (RSC), or app directory patterns.
Rust/WASM backend in api-rust/. High-performance alternative using workers-rs, utoipa for OpenAPI, and Supabase REST API. Port 9990 for local dev. 10-100x faster than Python.
Build FastAPI REST APIs with CORS, JWT auth, Pydantic validation, async endpoints, and proper error handling. Use when creating API endpoints, middleware, or backend services.
Backend API routes, database integrations ve server-side iş mantığı geliştirmek için kullanılır. Supabase, Zod validation, rate limiting ve API security konularında uzman.
Generate robust, secure Next.js 16 App Router API endpoints with validation, auth checks, and strict server-side enforcement.
This skill should be used when developing with the Hono web framework, including CLI tool usage, project scaffolding, routing, middleware configuration, testing, optimization, and deployment across multiple JavaScript runtimes (Cloudflare Workers, Deno, Bun, Vercel, AWS Lambda, Node.js)
Guidelines for creating API routes in Expo Router with EAS Hosting
FastAPI backend development with SQLAlchemy 2.0, Pydantic v2, and async Python. Use for API endpoints, database models, migrations, authentication, and background tasks.
Fastify framework patterns including routing, plugins, and decorators. Use when building Fastify APIs.
Generate FastAPI endpoint files with Pydantic models, dependency injection, and async handlers. Triggers on "create fastapi endpoint", "generate fastapi router", "python API endpoint", "fastapi route".
Build and extend FastAPI applications from hello-world to production-grade APIs. This skill should be used when users want to create new FastAPI projects, add features (routing, validation, auth, database integration, middleware), debug FastAPI-specific issues, or deploy applications to Docker/Kubernetes. Always fetches latest official FastAPI documentation before implementation to ensure correct API patterns and best practices.
Create database tables with Prisma ORM, migrations, and RLS policies. Use when user needs "create database table", "add [model] model", "set up RLS", "create migration", "store data in database", or "design schema". Generates Prisma models with proper naming conventions, creates migrations, sets up Row-Level Security policies, and syncs test database. Includes WorldCrafter patterns for relationships, tags, comments, activity logs, versions, world membership, collections, wiki pages, and bookmarks. Typically the FIRST skill for new features. Do NOT use for UI/forms (use worldcrafter-feature-builder), simple routes (use worldcrafter-route-creator), tests only (use worldcrafter-test-generator), or auth logic only (use worldcrafter-auth-guard).
Express.js patterns for routing, middleware, error handling, and RESTful API development. Trigger: When building Express servers, when implementing REST APIs, when setting up middleware, when handling authentication in Express, when structuring Node.js backends.
