Qwen4-max-preview thinking trace keeps repeating a URL guardrail reminder every turn

A Reddit user found that qwen4-max-preview's thinking trace contains an internal monologue repeated every turn: the model re-confirms it understands and complies with a URL tool reminder (URLs must match the task goal, no proxy substitution, re-verify sources each time) and asserts it has been complying throughout. The post includes the raw trace text and asks whether others are seeing the same behavior — an interesting window into how guardrail instructions are injected into reasoning models.
