What is form-creator?

A guide for building web forms with React Hook Form and Zod. React Hook Form manages form state, while Zod checks that submitted data has the expected shape and values.

Creating React forms, defining validation rules, handling submissions, and checking incoming API request bodies.

It sets one validation approach for both browser forms and API requests, helping prevent invalid data from being accepted.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00327
Opus 5.5	$0.00006	$0.00131
Sonnet 5.5	$0.00003	$0.00065
Haiku 4.5	$0.00001	$0.00033

Security

Grade A, and why

form-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Form Creator

Instructions

1. Client-Side Forms

Use react-hook-form for state management.
Use zod for schema validation.
Integrate using @hookform/resolvers/zod.
Use the Form components from @/components/ui/form.
Define schemas using z.object({...}).

2. API Validation

MANDATORY: Use zod schemas to validate incoming request bodies in API routes.
Share schemas between client and server if possible (e.g., in a separate file or exported from the component file if simple).

Example

Client

const form = useForm<z.infer<typeof schema>>({
  resolver: zodResolver(schema),
  defaultValues: { ... },
});

<Form {...form}>
  <form onSubmit={form.handleSubmit(onSubmit)}>
    {/* ... fields ... */}
  </form>
</Form>

Server (API Route)

import { z } from "zod";

const schema = z.object({
  name: z.string().min(2),
});

export async function POST(req: Request) {
  const body = await req.json();
  const result = schema.safeParse(body);

  if (!result.success) {
    return NextResponse.json({ error: result.error }, { status: 400 });
  }

  // ... process valid data ...
}

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
