Dummy tools stop Qwen reasoning loops

This clever "placebo" hack addresses models over-trained on tool-use patterns that continue reasoning until they find a function to call. Qwen models often loop or hallucinate JSON calls when they lack applicable tools, but providing a "Toolbox of Absurdity" gives the model a safe "no-match" exit path. This method significantly reduces repetition without complex management, highlighting how instruction-tuning can create rigid behavioral artifacts in open-weights models.
