What is it?

Key features

• 01Built-in software-change graph with implementation, parallel review, repair and optional delivery.
• 02Independent reviewers check the worker's output, and rejected work returns to repair.
• 03Custom graphs let you add security, test or parallel check nodes with per-node models.
• 04Saved profiles store graph and runtime settings for reuse across tasks.
• 05Optional delivery to a local branch, pull request, or PR and CI merge flow.
• 06Runs are recorded in a durable SQLite ledger and can be inspected in a browser UI.

Use cases

• Adding independent review and repair loops around Claude Code or Codex output before merging.
• Running security or test-focused reviewer agents alongside the implementation agent.
• Turning a task description into a reviewed pull request on a GitHub repository.
• Self-hosting agent workflows on your own infrastructure with the Docker target image.

Quick start

1. 1

   Install the CLI globally with npm

   npm install -g @the-open-engine-company/zeroshot
2. 2

   Create input.json with your task

3. 3

   Start a run with the software-change template

   zeroshot run \ --title "Add JSON status output" \ --template software-change \ --input input.json \ --uniform-runtime-config runtime.json

Things to know

• !Local runs require installing and signing in to a supported harness such as Codex, Claude Code, GitHub Copilot or Pi.
• !Running the workflow needs a model ID supported by your installed harness, and the worker edits the selected folder directly.
• !PR and ship delivery currently support only GitHub, and local GitHub delivery also needs the GitHub CLI.

FAQ

What is zeroshot?

A CLI and workflow engine that runs coding agents like Claude Code, Codex and Copilot through configurable review, repair and test gates before work is accepted. zeroshot turns a coding task into a reviewed change. A worker agent implements the task, then acceptance and code reviewers check the result in parallel. Rejected work goes back to a repair worker with the review feedback and is reviewed again. The agent that wrote the code cannot approve its own output, and the engine enforces the graph's review gates and retry limits.

Is zeroshot free to use? What license does it have?

zeroshot is open source under the MIT license. Check the license terms before using it in commercial products.
