## What it does

The skill covers four hooks from `next-safe-action/hooks`: `useAction`, `useOptimisticAction`, `useStateAction` and `useOptimisticStateAction`. You pick by action kind first — `.action()` goes with the first two, `.stateAction()` with the other two. Each hook comes with a client component example: the `"use client"` directive, `onSuccess` and `onError` callbacks, a disabled button driven by `isPending`.

Queued writes get their own section. `useOptimisticStateAction` takes `currentState` and `updateFn`, then holds each dispatch until the previous one settles. The server sees the last confirmed state as `prevResult`. That matters for drag-to-reorder lists, Kanban boards, or any place where someone moves an item twice before the first save lands.

A few things will break it. `currentState` has to be a stable reference, because it is compared by identity. With `<form action={formAction}>` the server action must be a `.stateAction()`, and the input schema has to parse `FormData` — `zod-form-data` is the example given. The action also has to revalidate the state the page renders, otherwise the optimistic result drifts from what the page shows.

Install with `npx skills add` and the flag for your platform.

## When to use it
- pick the right hook for an action kind
- make a checkbox toggle feel instant
- queue repeated reorders of a list item
- build a form on `<form action={formAction}>` that parses `FormData`
- surface a validation error next to its field

## Example prompts
- Pick the right next-safe-action hook for a feedback form
- Build a drag-to-reorder list with useOptimisticStateAction
- Why does my useOptimisticStateAction miss the previous state?
