Problem

Qwen-3.6 on llama.cpp displays raw tool-call XML instead of parsing it cleanly in OpenCode, showing <tool_call> or <function> tags inside or right after its reasoning (<think>) blocks, and the chat template fails intercept and parse them. Using the “Expand thinking” functionality in OpenCode was critical for discovering the XML blocks that were emitted but not executed as tool-calls.

Solution

Replaced unsloth/Qwen3.6 with peculiar-ragdoll/Nail-Qwen3.6 that resolves the tool use issue in OpenCode.

I’ll be using this blog to track issues, experiments, and interesting subjects I’m learning along the way.
