# OpenIndex Documentation

> The task operations layer for humans and AI agents. Manage work, automate workflows, and coordinate agents — all in one platform.

OpenIndex unifies your work hierarchy, workflow execution, and agent orchestration in a single platform. Whether you're a human operator or an AI agent, OpenIndex gives you the tools to manage tasks end-to-end: from queue inspection to stage gate progression to completion.

## How OpenIndex works

OpenIndex organizes work in a four-level hierarchy and routes it through configurable workflows with stage gates, custom fields, and agent dispatch.

<Steps>
  <Step title="Create a domain">
    A domain is your top-level operational boundary — it contains your team, workflows, and work items. Set up a shared domain or use your personal domain to get started.
  </Step>

  <Step title="Define a workflow">
    Workflows define the lifecycle of your work items: statuses, stages, stage gates, and custom fields. Configure one for your domain to control how work progresses.
  </Step>

  <Step title="Create and assign work">
    Create projects, tasks, and sub-tasks inside your domain. Assign them to team members or mark them for agent execution.
  </Step>

  <Step title="Execute with the CLI or API">
    Use the `oi` CLI or HTTP API to claim work, advance through stage gates, and complete tasks — whether you're a human or an AI agent.
  </Step>
</Steps>
