# Assets upload, schema discovery, and improved image field validation

**Version:** v2.30.0

## New Features

- Assets upload: Agents can now use the `dataset_assets_upload` tool to upload supported image and file types via local Sanity CLI.

## Improvements

- `generate_image` and `transform_image` tools: Improved path validation for image fields in documents.
