a claude code/codex plugin to run autoresearch on your repository

i built

https://github.com/evo-hq/evo

for those of you who are autoresearch pilled , or have been meaning to get into autoresearch but dont know how. Its an opensource Claude Code & Codex plugin that optimizes code through experiments

you hand it a codebase. it finds a benchmark, runs the baseline, then fires off parallel agents to try to beat it. kept if better, discarded if worse.

inspired by karpathy's autoresearch, but with structure on top:

• tree search over greedy hill-climb — multiple forks from any committed node


• N parallel agents in git worktrees


• shared failure traces so agents don't repeat each other's mistakes


• regression gates

under the hood: each experiment is a git worktree branching from its parent. commits on score improvement + gate pass. discards + worktree cleanup on regression. everything observable in a local dashboard

Apache 2.0, no signup, no API keys beyond what Claude Code already has:

/plugin marketplace add evo-hq/evo

/plugin install evo@evo-hq-evo
