- **Enabled when:** react

## Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Confirm the reported code matches Async effect callback. Check the framework context and diagnostic message before suppressing it.

## Fix prompt

Use this once validation confirms the diagnostic is real.

Don't make the effect callback `async`. Define an async function inside the effect and call it, then return a real cleanup function if you need one.
