Release Notes

v2.3.3

Compare Source

Patch Changes

• #​445 16db454 Thanks @​robert-j-y! - fix: strip reasoning.text entries without valid signatures (#​423/#​439)

  When reasoning_details exist but reasoning.text entries lack a signature (lost during custom pruning, DB serialization, or model switching), Anthropic rejects with "Invalid signature in thinking block". This adds validation to filter out signatureless reasoning.text entries before sending to the API.

v2.3.2

Patch Changes

• #​446 b1ccc53 Thanks @​robert-j-y! - Fix multimodal tool results being flattened to strings

  When a tool returns output.type = "content" with structured multimodal parts (text + images), those parts were being JSON.stringified instead of preserved as structured content parts. This prevented models from using vision on images in tool results.

  Changes:

  • getToolResultContent() now maps each content part to the appropriate OpenRouter format (text, image_url, file) instead of stringifying
  • ChatCompletionToolMessageParam.content type updated to accept string | Array<ChatCompletionContentPart>

  Fixes #​181
