CausalSteward: An Agentic Divide-Conquer-Combine Copilot for Causal Discovery

Nicholas Tagliapietra, Gian Lorenzo Marchioni, Moritz Willig et al.

What this work does

Partitions high-dimensional variables, combines LLM/human prior knowledge with data-driven discovery in local graphs, and merges results through hypothesis/critic agents.

Connection to discovery

Exposes a testable boundary between domain-knowledge proposals, statistical tests and final graph commitments in a harness.

Evidence

Inspected how proposed graphs constrain a discovery algorithm and how cross-partition edges are added during merging.

Scope and limitations

Incorrect priors and partitioning can bias graphs; identifiability claims depend on assumptions and available evidence. The selected review did not independently check the theoretical proofs or reproduce experiments.
