Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Evo is a plugin for Claude Code and Codex that autonomously optimizes codebases through parallel experiments. It extends the autoresearch concept by implementing tree search with multiple parallel agents, shared state tracking, and gating mechanisms. This approach enables systematic exploration of code improvements beyond simple hill climbing.

Target audience: backend devs, devops, ai engineers
