AgentCheck: A Reproduce-Intervene-Mitigate Workbench for LLM Agents over MCP
Aritra Mazumder, Nusrat jahan Lia
Tool-using LLM agents are mostly evaluated assuming all tools work. When a tool times out, returns a week-stale value, or has its description poisoned in deployment, the developer…
Learning What Not to Forget: Long-Horizon Agent Memory from a Few Kilobytes of Learning
Nusrat Jahan Lia, Aritra Mazumder
Long-running language-model systems accumulate interaction history that outgrows the context window, so they must continually evict. When an eviction policy drops a task-critical d…
AgentCollabBench: Diagnosing When Good Agents Make Bad Collaborators
Aritra Mazumder, Shubhashis Roy Dipta, Nusrat Jahan Lia +10
Multi-agent systems achieve state-of-the-art outcomes through peer collaboration. However, when an agent in the pipeline silently drops a constraint, the system's final output may…
Phonon anharmonicity and soft-phonon mediated structural phase transition in
Debabrata Samanta, Aritra Mazumder, Sonu Pratap Chaudhary +4
We have carried out temperature-dependent x-ray diffraction and Raman scattering experiments on powder . Trigonal to monoclinic structural transition at around 95 K i…
Pressure induced lattice expansion and phonon softening in layered
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +2
We report high pressure X-ray diffraction and a detailed systematic Raman measurements on sample, which is mechanically exfoliated from a single crystal. A few new Bragg pe…
High pressure anomalies in exfoliated : Resonance Raman and X-ray diffraction studies
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +1
Detailed high pressure Resonance Raman () Spectroscopy and X-ray diffraction () studies are carried out on 3-4 layered obtained by liquid exfoliation. Analysis of…
