nextjs-tanstack-form skillA
nextjs-tanstack-form is agent-read markdown (skill) from fusengine/agents: Use when building forms in Next.js 16 with TanStack Form v1 — Server Actions, Zod validation, multi-step wizards, field arrays..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective> Implements TanStack Form v1 in Next.js 16 with native Server Actions integration: shared `formOptions` (single source of truth for client and server), Zod schemas for both instant client feedback and `onServerValidate` database checks, `useActionState` for the React 19 form-submission hook, and `mergeForm` to combine server-returned errors with client state. Covers the Field API (state + handlers), validation timing (onChange/onBlur/onSubmit/onServer), dynamic field arrays and multi-step wizards, debounced async validation, and shadcn/ui field composition. Also documents SOLID file organization for forms (`form-options.ts`, `FormComponent.tsx`, `form.action.ts`) and a comparison against React Hook Form. This is the Next.js Server Actions variant of TanStack Form — for a plain React app without Next.js see the react-forms skill. </objective> # TanStack Form for Next.js 16 Type-safe, performant forms with Server Actions and signal-based reactivity. ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing forms and validation patterns …
