Review Completed

Since issue #440 has no directly linked PR, I reviewed PR #396 ("Tools can also return DocumentBlock, ImageBlock, VideoBlock") which relates to the ToolUse and ToolResponse messages topic.

PR #396 Review Summary

Key Changes:

• Added ToolReturnValue type supporting media blocks (Document, Image, Video)
• Enhanced tool() helper to accept media block returns
• Updated Bedrock formatting to handle media content natively
• Updated ToolResultContent type to include media blocks

Feedback Provided:

1. OpenAI model needs handling for media blocks in tool results (currently returns empty string)
2. Test coverage should include ImageBlock and VideoBlock (only DocumentBlock is tested)

Status: Left review comments on PR #396 with specific suggestions.

---

If there's additional work planned for issue #440 beyond PR #396, please create a PR and request another review.
