Developer Builds Rust ML Library Using Agents

On 27 February 2026, Max Woolf—an AI agent coding skeptic—documents a sequence of agent-assisted coding projects culminating in "rustlearn", a Rust crate that ports scikit-learn algorithms and claims performance improvements over scikit-learn. He highlights recent model leaps (Opus 4.6/Codex 5.3) that enabled rapid implementation, and notes Claude Code also generated a Rust word-cloud CLI, illustrating agents' practical use for library prototyping and tool production.
