Zeroshot AI Agent

<div align="center">

zeroshot

A multi-agent orchestration engine that keeps coding agents from grading their own work.

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

Runs locally on top of your agent subscription.

As a coding agent's context fills up, it forgets requirements, stops questioning its own assumptions and calls the work done, even when you tell it to check its work.

The agent that wrote the code shouldn't be the one that says it works (see our benchmark).

So zeroshot runs your process as a graph the engine enforces. You decide who writes, who reviews, what must pass and where failures loop back, and pick the agent and model for each step. Every task runs through that graph, no agent can skip a step, and the graph, not the agent, decides what happens after a review.

How it works

An example graph: independent reviews, end-to-end testing, and CI must pass before merge.

Save your graph as a reusable profile and run the same process across tasks.

See more graph examples on zeroshot.sh.

Get started

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

The CLI installer adds skills for Claude Code, Codex, Copilot CLI and Pi. See installation options to skip skill installation.

Use zeroshot in ChatGPT, Codex, or Claude with the plugin and MCP connection; the zeroshot CLI is optional for Platform workflows.

Run a first task

Open your agent in a repo and ask for a change. For example:

use zeroshot to let users export their data as CSV. Keep the changes local.

Run locally with your agent's existing login and subscription. Watch with zeroshot ui. The CLI quick start walks through a run directly in the terminal.

Design your own graph

To choose your own agents, models, review gates, and delivery, ask:

design a zeroshot graph for this repo

The skill reads your repo and builds the graph with you. Then plan a task:

plan this with zeroshot: let users export their data as CSV

Run the plan:

zeroshot it

Edit a graph directly

Export a template with Git delivery disabled:

zeroshot template show software-change --delivery none > graph.json

Edit the graph, choose a runtime, and run it. The review loop guide has complete graph, input, and runtime files.

Features

Graphs and agents

One graph per process your team runs.

• Graphs are JSON: steps, reviewers, branches, parallel work, bounded loops and maps over lists.
• Profiles: save each graph by name and pick one per run with --profile.
• Agent and model per node: Claude Code, Codex, Copilot CLI, Pi and more, through the providers each agent supports: OpenAI, Anthropic, OpenRouter, Bedrock, Foundry or your own endpoint.
• Delivery: a run can end by pushing a branch, opening a PR, or opening and merging one on GitHub, GitHub Enterprise or GitLab, or by leaving the change in your working copy. The built-in template software-change defaults to PR delivery.
• Plans: plan this with zeroshot turns a big change into small PRs, each with the tests it must pass.

The engine enforces them

Agents do the work. The graph decides what happens next.

• Checked before it runs: type mismatches, unbounded loops and unreachable branches are rejected before any agent starts. --validate-only runs just the checks.
• Reviewers route the run: each reviewer returns an enum verdict, and the graph routes on it.
• Script steps: run a deterministic command as a step in local runs.
• Secrets stay out of the record: credentials are stored once as named connections and kept out of graphs, run history, logs and the UI.

See inside every run

• zeroshot ui: each node's input, output and logs in the browser, on a timeline you can replay.
• CLI: status and list return JSON, watch and logs stream resumable events, attach follows a running agent.
• SQLite: one SQLite file per local run.
• Resume: restart a failed run from a checkpoint without redoing finished steps.

Build on it

Drive zeroshot from your own code, CI or UI.

• Python SDK: async Python client for submitting, watching and waiting on runs. Each wheel bundles the matching zeroshot binary.
• JSON-RPC API: run zeroshot target serve and connect over WebSocket to submit runs, watch their status and which nodes are running, and stream logs. An OpenRPC spec describes the methods.
• API keys: expiring, revocable CI keys for hosted targets.
• Agent adapters: add support for another coding agent through a documented contract.

Hosting

Run locally on your Claude, ChatGPT or Copilot subscription, self-host with Docker, or share graphs and run on zeroshot Platform using your own model API keys.

zeroshot sends no telemetry. The CLI contacts GitHub only to install or update, and otherwise only the model providers, Git hosts and targets you set up. See network access.
