Polis Protocol
The local-first control plane for coding agents. Run Claude, Codex, Gemini, and Cursor against one repo — each claimed contract records an owner, agents can record evidence, and shared lessons help reduce repeated failures. Plain markdown, in git, across every vendor.

Synthetic simulation: repeat errors 65% → 7% · Advisory overlap conflicts detected · reproduce in 5s: polis bench --mode learning Modeled run with synthetic tasks and seed 0 — assumptions and limitations are published below.

The 10-second version
Three AI agents share one project: Claude (research), Codex (frontend), Gemini (translation).
A Spanish-translation task comes in. Who gets it?
Early on, Claude did — it rated itself highly. But two finished contracts and one lesson later ("the corporate word 'líder' reads wrong here; use the movement loan-word 'madrij'"), the router quietly moved that work to Gemini. Nobody reassigned it. The team learned, and the routing followed.
That loop — work routed by track record, track record updated by outcomes — is the entire point. See it yourself in one command, no install, no API keys:
git clone https://github.com/ymxlx/polis-protocol.git
cd polis-protocol && bash scripts/demo.shScore breakdown (sorted by total):
