Check Existing Issues

  • I have searched for all existing open AND closed issues and discussions for similar requests. I have found none that is comparable to my request.

Verify Feature Scope

  • I have read through and understood the scope definition for feature requests in the Issues section. I believe my feature request meets the definition and belongs in the Issues section instead of the Discussions.

Problem Description

The Anthropic-to-OpenAI payload conversion in utils/anthropic.py only handles text content within tool_result blocks. When a tool call returns an image (or other content types like search_result, document), the content is silently dropped — the request goes through but the model never sees the tool output.

This affects anyone using the Anthropic-compatible endpoint with tools that return multimodal results.

Desired Solution you'd like

support for images and string content in Anthropic tool_result
