- Add proper error handling for JSON marshal in StreamConverter to
prevent corrupted streams when tool arguments cannot be serialized
- Add tests for unmarshalable arguments and mixed validity scenarios
- Fix documentation typo and update recommended models to qwen3-coder
Add middleware to support the Anthropic Messages API format at /v1/messages.
This enables tools like Claude Code to work with Ollama models through the
Anthropic API interface.
Features:
- Request/response transformation between Anthropic and internal formats
- Streaming support with SSE events (message_start, content_block_delta, etc.)
- Tool calling support (tool_use and tool_result content blocks)
- Thinking/extended thinking block support
- Image content block support (base64)
- System prompt handling
- Multi-turn conversation support
- Proper stop_reason mapping (end_turn, max_tokens, tool_use)
- Error responses in Anthropic format
