type-safety-design

What problem does it solve?

Ensures that runtime data, configuration, and protocol messages conform to expected types and schemas to prevent runtime failures and protocol mismatches. It bridges compile-time TypeScript guarantees with runtime validation so that configuration, API payloads, and inter-service messages are both well-typed and validated.

Core Features & Use Cases

• Schema authoring with TypeBox for runtime-aware schemas and Zod for configuration validation.
• Runtime validation via generated AJV validators and explicit validation layers that return structured errors and repair suggestions.
• Code and doc generation that emits TypeScript types, JSON Schema, client models, and API documentation from a single schema source.
• Integration scenarios: validate loaded configuration files, enforce API contracts at gateway boundaries, generate client models for multi-language SDKs, and plug into a modular plugin system.
• Performance & reliability: supports batching, caching of validation results, and schema modularization to limit validation overhead.

Quick Start

Use the type-safety-design skill to validate a TypeBox schema against incoming JSON data and generate corresponding TypeScript types and a JSON Schema document.
