# Zeroshot and Opcore

by The Open Engine · [Agent orchestration](/software-factories/category/agent-orchestration.md) Open source

Open-source tools that run your own coding agents with independent checking and block bad edits before they land.

## Overview

Zeroshot and Opcore come from The Open Engine, which builds open-source tools for making AI-written code trustworthy and describes itself as an autonomous software factory.

Zeroshot drives the coding agents you already use, such as Claude Code and Codex. One agent writes the change, a separate agent that never saw the work checks it, and Zeroshot can then open and merge the pull request. Opcore is a local gate that runs after each agent edit and blocks type errors and bad imports.

The Zeroshot CLI and workflow engine are free and MIT licensed. Zeroshot Cloud is the paid hosted version, priced by how many jobs run at once.

## Features

* Drives your own coding agents, such as Claude Code and Codex.
* Has one agent write a change and a separate agent, which never saw the work, check it.
* Can open and merge the resulting pull request.
* Opcore runs locally after each agent edit and blocks type errors and bad imports.
* Zeroshot Cloud runs the same workflow as a hosted service.
