Yoyo-Evolve puts autonomous code evolution on public display

A Rust-based coding agent is running an unattended self-improvement loop: it reads its own code and journal, processes external GitHub issues, ships changes when tests pass, and reverts on failure. The project has grown from ~200 to 1,500+ lines in four days, with public logs showing both real progress and realistic failure patterns.

// ANALYSIS

This is a compelling real-world stress test for agentic coding because it exposes long-horizon behavior, not just one-shot demos.

–Public commit history and journals make agent progress auditable, which is rare for autonomous coding experiments.
–Self-filed issues and deferred tasks show early planning behavior, including prioritization failures like repeated streaming procrastination.
–The loop design (test-gated commits plus rollback) is a practical safety pattern for autonomous code changes.
