"""Tests for AnthropicProvider._tool_result_block image_url conversion.
|
|
|
|
Regression for: tool results containing OpenAI-format image_url blocks
|
|
(e.g. from read_file on an image file, via build_image_content_blocks)
|
|
were passed to Anthropic unconverted, causing silent image drops with a
|
|
"Non-transient LLM error with image content, retrying without images"
|
|
warning.
|
|
|
|
Also tests that bare dicts without a "type" field are coerced to text
|
|
blocks, fixing Anthropic "content.0.type: Field required" rejections (#3993).
