Researchers Plant Canary Tools to Diagnose AI Agent Selection Flaws

Researchers introduce "canary tools," a diagnostic method planting traps in an AI agent's toolset to investigate why models pick the wrong tools.
- Trap Taxonomy: Defines six trap types (e.g., semantic decoys, parameter traps, capability mirages) to turn a single "wrong tool" outcome into a multi-dimensional reasoning profile.
- Experiment Scale: Evaluates 8 models across 120 tasks in 8,640 runs, plus a 2,880-run ablation.
- Key Findings: Susceptibility drops sharply as models get more capable (a 36x difference). However, capability tier alone doesn't predict safety; the most susceptible hosted model was a mid-tier one.
