- What happened
- CausalForge automates theoretical research in causal inference using Lean proof assistant, combining a formal library with an AI agent that proposes, formalizes, and proves results.
- Why it matters
- Matters for researchers building automated systems for mathematical discovery and for those working on formal verification of AI-generated theoretical claims.
- Watch out
- Machine-checked proofs only verify formal statements follow from assumptions, not that formal statements capture intended scientific meaning. Statement audits attempt to bridge this gap but remain a key limitation.

Abstract: Automating theoretical research is constrained not only by the generation of candidate results, but also by their reliable evaluation. A common approach is to close the research loop with a large language model (LLM) reviewer. However, such reviewers remain empirically unreliable: they may accept fabricated papers and detect them at rates close to chance (Bad Scientist, 2025). We present CausalForge, a framework for automated theoretical research in causal inference grounded in the Lean proof assistant. CausalForge combines Causalean, a foundational Lean library for causal inference containing 7,035 machine-checked declarations developed with language-model assistance under human design and review, with CausalSmith, a self-improving agentic pipeline that selects research topics, proposes results, formalizes statements, constructs proofs, and presents the resulting artifacts for human inspection. Because a machine-checke
