During February 2026, Kuccello developed enhanced XML tool call parsing for the block/goose repository, focusing on improving Qwen3-coder’s interoperability with the Ollama provider. He implemented a robust fallback mechanism and new parsing logic in Rust, enabling the backend to accurately interpret XML-style tool calls when models output XML instead of JSON. This approach reduced parsing errors and improved response handling, ensuring that XML-formatted tool calls were processed correctly across providers. Leveraging skills in API integration, backend development, and stream processing, Kuccello addressed compatibility challenges and delivered a targeted feature that deepened the system’s support for diverse model outputs.
