Minimal Bash-Only Lean Agent Aces Putnam 2025

A paper (arXiv:2610.17331) introduces mini-Lean-agent, a deliberately minimal Lean theorem-proving agent whose only visible tool is bash. It scored 12/12 on Putnam 2025 at $1.28 per problem, suggesting modern models can handle hard proofs without complex search tooling.
