Qwen3.6-35B-A3B fails on array tool inputs

Qwen3.6-35B-A3B is an impressive MoE model, but its tool-calling reliability is hit-or-miss for complex agentic tasks.

• –The model incorrectly formats array parameters as stringified JSON (e.g., ["cmd"] becomes "[\"cmd\"]"), breaking standard tool execution.
• –Even when provided with error feedback, the model often fails to correct its formatting in subsequent turns.
• –Developers are forced to use "dirty" pre-parsing layers or custom Jinja templates to work around these formatting drifts.
• –Despite these issues, its coding performance (SWE-bench Verified: 73.4) remains highly competitive for its size.
