Validate API requests with schemas, sanitization, and helpful error messages. Covers Zod, Joi, and Pydantic patterns.
Scaffold a new Next.js route with tRPC router, Zod validation, and proper file structure
Build type-safe validated forms using React Hook Form v7 and Zod v4. Single schema works on client and server with full TypeScript inference via z.infer. Use when building forms, multi-step wizards, or fixing uncontrolled warnings, resolver errors, useFieldArray issues, performance problems with large forms.
Extracts structured data from LLM responses using JSON schemas, Zod validation, and function calling for reliable parsing. Use when users request "structured output", "JSON extraction", "parse LLM response", "function calling", or "typed responses".
Type-safe API route handler with automatic Zod validation for Next.js App Router...
How to add or modify Next.js experimental feature flags end-to-end. Use when editing config-shared.ts, config-schema.ts, define-env-plugin.ts, next-server.ts, export/worker.ts, or module.compiled.js. Covers type declaration, zod schema, build-time injection, runtime env plumbing, and the decision between runtime env-var branching vs separate bundle variants.
TanStack Form v1 for Next.js 16 with Server Actions, Zod validation, and shadcn/ui integration. Use when building forms, validation, multi-step wizards, or dynamic field arrays.
Use this skill when building with the okfetch library. It helps agents choose between @okfetch/fetch, @okfetch/api, and @okfetch/logger, and shows the expected Result-based and Zod-based usage patterns.
Write and refactor TypeScript code in repos that use Effect-TS services, Zod schemas, event-sourced persistence, and namespace-driven architecture. Use this skill when implementing features, fixing bugs, writing tests, or refactoring in opencode or any TypeScript codebase built on the same stack (Effect DI, Drizzle ORM, Hono routes, Bun runtime). Triggers on tasks involving Effect services, namespace modules, Zod schema definitions, SyncEvent patterns, tool implementations, test writing, or code review in Effect-based TypeScript projects.
Hono request validation with Zod, TypeBox, Valibot - type-safe input validation for JSON, forms, query params, and headers
This skill provides comprehensive knowledge for building type-safe, validated forms in React using React Hook Form and Zod schema validation. Use when: building forms with validation in React, integrating Zod schema validation with React Hook Form, using shadcn/ui Form or Field components, implementing client and server-side validation with a single schema, handling complex validation scenarios (nested objects, arrays, conditional fields, async validation), building multi-step forms or wizards, implementing dynamic form fields with useFieldArray, optimizing form performance and re-renders, ensuring accessible form error handling, or debugging form validation issues.

Enforces the CodeBelt TypeScript and React code style guide for project structure, naming conventions, component patterns, service patterns, testing, and TypeScript rules. Use when writing, reviewing, or refactoring TypeScript or React code, creating new files or components, organizing project directories, writing tests, defining Zod schemas, or when the user mentions code style, conventions, linting, file organization, or naming patterns.
