Gold definitionUpdated Apr 2, 2026

Definition

Numina-Lean-Agent is an agentic system for formal theorem proving that leverages a general coding agent (Claude Code) as a math reasoner. It integrates with Numina-Lean-MCP to interact with Lean, retrieve theorems, and perform informal proving, achieving strong performance and generality without task-specific training.
