# CognitionAcp.FolderMutationResponseMeta

> Metadata for a folder mutation response's , using keys.

Metadata for a folder mutation response's `_meta`, using `cognition.ai/`
keys.

A folder-level mutation changes the folder directory itself, so the
response refreshes it wholesale — including empty folders, which no
session meta can describe — and clients resync from it instead of waiting
for the next `session/list` poll.

```typescript
type FolderMutationResponseMeta = void
```
