# React 19 Server Actions & Progressive Form Mutations

Implements React 19 / Next.js Server Actions: 'use server' directives, progressive enhancement without JavaScript, optimistic UI responses, automatic cache invalidation, and integrating Zod input schema validation.

## When to Invoke
Invoke this skill whenever you need to:
- write react 19 server action
- progressive enhancement form nextjs
- zod validate server action

## Execution SOP & Rules
1. Declare 'use server' at top of action function or standalone server action module.
2. Validate FormData with safeParse using Zod: const validated = schema.safeParse(Object.fromEntries(formData)).
3. Return structured response: { success: true, data } or { success: false, errors }.
4. Call revalidatePath() or revalidateTag() upon successful database mutation.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
