- description
- Add reactivityKeys to effect-atom write mutation calls. Use when lint flags a useAtomSet mutation call that mutates data without invalidation keys.
- allowed-tools
- Read Grep Glob Bash
Effect-atom write mutations must say which reads they invalidate.
## Fix Shape
- Find the `useAtomSet(...)` write mutation call.
- Add `reactivityKeys` to the mutation payload at the call site.
- Use the narrowest keys that cover the rows/lists affected by the write.
- Keep read-only probe/preview OAuth flows out of this pattern.
- If the mutation should update UI immediately, check whether `wrdn-effect-atom-optimistic` also applies.
## Good
```ts
await updateSource({
params: { scopeId, sourceId },
payload,
reactivityKeys: [["sources", scopeId]],
});
```
