Active Causal Discovery Benchmark: Evaluating LLM Agents Under Budgeted Interventions

Sagar Deb, Devam Shah, Ashwanth Krishnan

What this work does

Generates linear-Gaussian SCMs with an observe/intervene/submit protocol and separate skeleton, directed-graph and intervention-efficiency scores.

Connection to discovery

A direct environment for testing causal experiment selection separately from observational structure inference and overconfident edge commitment.

Evidence

Inspected hard-intervention budgeting, partial orientation submissions and the audit showing a surprisingly high structure-blind random-graph floor.

Scope and limitations

The initial dense ladder requires calibration and has small graph sizes, causal sufficiency and linear-Gaussian assumptions. The paper explicitly frames current results as an audit, not solved causal discovery.
