## What it does

The skill maps out ways to use `next-safe-action` with forms. It covers `useAction`, `useStateAction`, the React Hook Form adapter through `useHookFormAction` and `useHookFormOptimisticAction`, field-level validation errors, bound arguments, and uploads.

For a native form, the action can receive `FormData` through `formAction`, or the submit handler can build an input object before calling the action. The React Hook Form route connects a schema resolver, registered fields, and the action result. With `useStateAction`, the server action must use `.stateAction()`, while its input schema must parse `FormData`, such as with `zfd.formData` from `zod-form-data`.

The skill also points to material on native form patterns, the React Hook Form adapter, and file uploads. A project using `useStateAction` without `.stateAction()` will fail at this integration point.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add next-safe-action/skills --skill safe-action-forms -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/safe-action-forms/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/safe-action-forms/

### Codex

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add next-safe-action/skills --skill safe-action-forms -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/safe-action-forms/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

## When to use it
- connect next-safe-action to a native HTML form
- render validation messages beside individual fields
- wire React Hook Form to a server action
- add optimistic updates to a form
- handle bound arguments or file uploads

## Example prompts
- Connect `next-safe-action` to a contact form with `useStateAction` and render its validation errors.
- Build a React Hook Form integration with `useHookFormAction`, a `zod` schema, and field messages.
- Show how to handle a file upload with `next-safe-action` and choose the matching form submission pattern.
