Why Agents Call Unneeded Tools and How to Tackle It as a System‑Engineering Problem

The article defines tool hallucination in LLM agents, analyses training bias, context pollution, loop feedback and dialogue inertia as root causes, and proposes multi‑layer defenses—including visibility control, intent verification, runtime gating, architectural isolation, and feedback loops—framed as a system‑engineering challenge rather than mere prompt tweaking.
