How to write Malli schemas for Guardrails function specifications in Clojure/ClojureScript. This skill teaches the schema types available, map schema patterns, and best practices for type-safe function definitions using >defn.
Generates new Go HTTP handlers following Ishkul patterns. Creates handler with proper request/response types, error handling, validation, structured logging, and matching test file. Use when adding new API endpoints.
Provides patterns for structuring the API layer in React applications. This skill should be used when setting up API clients, defining API request declarations, or integrating with TanStack Query for data fetching.
Scaffolds a new FastAPI endpoint with Pydantic models, router registration, and tests. Use when creating new backend API endpoints. Related: pydantic-model-scaffolder for complex model validation.
Builds high-performance FastAPI applications with async/await, Pydantic v2, dependency injection, and SQLAlchemy. Use when creating Python REST APIs, async backends, or microservices.
Error handling with error classes, handlers, and interceptors. Use when handling API errors, displaying validation errors, configuring error handlers, or implementing error interceptors.
A comprehensive pattern for building type-safe forms and API validation using Zod, with automatic error formatting, runtime type checking, and seamless TypeScript integration. Use when building forms with client-side and server-side validation, validating API request/response payloads, creating reusable validation schemas, or ensuring data integrity across client and server.
Create Prisma model layer functions. Use when adding database operations. Never call Prisma directly in routes.
Use when working with JSON Schema for validation, including draft-07, 2019-09, and 2020-12 specifications
Add new API endpoints to the OpenGov SDK from an OpenAPI specification. Use when: (1) Adding a new resource module (e.g., fees.py, transactions.py) (2) Adding endpoints to an existing module (3) User provides an OpenAPI spec file path or asks to "add endpoints" or "implement API methods" Creates: endpoint module, Pydantic models (params, response, enums), tests, and exports.
Apply when validating API request inputs: body, query params, path params, and headers. This skill covers Zod v4 patterns.
Generate Django REST Framework serializers with validation, nested relationships, and best practices. Use when creating or updating API serializers, especially for complex models with relationships.
Fetch reference implementations from core-supabase repository. Use when (1) implementing Repository layer with Supabase, (2) need RPC function usage patterns, (3) checking correct parameter structures and type assertions, (4) verifying Supabase integration patterns.
Provides comprehensive guidance for input validation, data serialization, and ID management in backend APIs. This skill should be used when designing validation schemas, transforming request/response data, mapping database IDs to external identifiers, and ensuring type safety across API boundaries.
Comprehensive guide to building production-ready REST APIs in Rails with serialization, authentication, versioning, rate limiting, and testing
TypeScript patterns for full-stack Next.js applications. This skill should be used when implementing type-safe API contracts, utility types, Zod schema integration, tRPC type inference, or type derivation patterns. Covers RouterOutputs/RouterInputs, branded types, discriminated unions, and server-first typing strategies.
Create REST API endpoints with proper validation, error handling, and Swagger documentation. Use when adding new routes, HTTP handlers, or REST API functionality.
Build production-ready RESTful APIs with Express.js including routing, middleware, validation, and error handling for scalable backend services
