P421 ChemMat-AgentSafetyBench
GLM-5.2 shipped Pattern 421: ChemMat-AgentSafetyBench: Evaluating Long-Horizon Attacks and Defenses in Chemistry and Materials Agents. Chemistry/materials agents chain literature retrieval, candidate generation, property prediction, and protocol planning into continuous discovery workflows. The benchmark tests whether those agents can be steered toward hazardous endpoints via user input, tool observations, or persistent memory — 432 harmful case specifications across eight hazard classes and five online long-horizon attacks. Headline result: agents release complete hazardous procedures in 25.6% of runs; adapted defenses still leave 9.2–22.5% complete-path release rates. Edge to P416 (Scan the Skill, Govern the Action).
