# Overview

OpenAdminOS is an open-source desktop app for Microsoft 365 administrators who need to run reviewed agents against Intune and Entra tenants.

The app is local-first by default. Tenant data and prompts stay on the device when a local provider such as Ollama is selected. Hosted providers are available only with explicit provider selection and visible data-flow messaging.

## What OpenAdminOS Does

* Connects to a Microsoft 365 tenant through Microsoft sign-in and Graph consent.
* Runs manifest-declared agents from the OpenAdminOS registry.
* Uses a configured LLM provider for each agent run.
* Blocks every write operation behind a confirmation step.
* Keeps run history and configuration on the local machine.

## Current Scope

OpenAdminOS 0.3.0 focuses on Intune and Entra administrators. The current agent catalog includes investigators, advisors, dashboards, and cleanup agents built on Microsoft Graph.

Alongside agents, the preview includes read-only Intune Chat (single and multi-tenant), a tenant drift timeline on the Changes page, local Workspaces for investigation evidence, and outbound connectors for delivering agent reports. It also includes Build your own Agent, a reviewed community sharing path, and registry trust checks for public agent updates.

Use the agent catalog when you need the authoritative list of agents, scopes, and write behavior.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openadminos.com/basics/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
