Evo turns codebases into autoresearch loops

Evo is an open-source Claude Code and Codex plugin that sets up a reusable optimization loop for codebases. It discovers a measurable target in the repo, spawns parallel subagents to run experiments in isolated git worktrees, keeps the commits that improve the score, and discards the rest. The pitch is less “one-off coding assistant” and more “autonomous experiment harness” for improving benchmarks, pass rates, latency, or other custom metrics without rebuilding the orchestration every time.

// ANALYSIS

Strong idea, and the differentiation is in the workflow mechanics rather than the model layer.

–The tree-search framing is the real product: it avoids the brittleness of a single greedy branch and gives experiments a persistent search structure.
–Worktree isolation plus commit-based acceptance is a practical way to keep experiments auditable and reversible.
–The semi-autonomous subagent setup should work well when failure traces are informative and the objective is measurable.
–The hardest part is not spawning agents, it’s defining robust scoring and regression gates; that is where most “autonomous optimization” systems usually fail.
–Because it works across hosts like Claude Code and Codex, it has a better chance of being reused as infrastructure rather than a prompt trick.
