name	wrdn-effect-atom-reactivity-keys
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

await updateSource({
  params: { scopeId, sourceId },
  payload,
  reactivityKeys: [["sources", scopeId]],
});
