Reference information for Autonomous Engineer, including work item states, agent packs, and supported capabilities in Build Agent.
This section contains reference information for Autonomous Engineer. Use it to look up work item states, agent pack details, and supported capabilities.

## Work item states {#autonomous-engineer-reference-landing__cf-reference-parent-work-item-states}

For a list of work item states and their definitions, see [Autonomous Engineer plan and work item states](https://www.servicenow.com/docs/_G_XpYpkDmENvUMWR1gHig "Plan and work item states appear during planning and execution. Use this reference to identify where a plan or work item is in the execution process and what action is required.").

## Agent packs {#autonomous-engineer-reference-landing__cf-reference-parent-agent-packs}

Autonomous Engineer uses agent packs with product-specific domain knowledge to run implementations. For details on available agent packs, see [Agent packs for Autonomous Engineer](https://www.servicenow.com/docs/oVjM4G645d4FZBznnYxwIg "Agent packs bundle the domain knowledge, tools, and skills that Autonomous Engineer uses to implement ServiceNow products.").

## Limitations {#autonomous-engineer-reference-landing__cf-reference-parent-limitations}

For information on limitations that apply to Autonomous Engineer and Build Agent, see [Build Agent limitations](https://www.servicenow.com/docs/a7CuW5zJEH_duHsbWop2wQ "Plan deployments and troubleshoot issues by learning about Build Agent constraints that affect deployment capabilities and performance.").

* **[Domain separation support in Autonomous Engineer](https://www.servicenow.com/docs/s2QCEJTey1BAsgPjPYan1w)**   
  Autonomous Engineer supports domain separation, allowing you to set the domain (`sys_domain`) and use `sys_override` on APIs and records that support it.
* **[Supported metadata in Autonomous Engineer](https://www.servicenow.com/docs/dEH58aEB36NdB0WUqmw2sw)**   
  Metadata and app file types that Autonomous Engineer can create and manage.
* **[Supported file types for Autonomous Engineer](https://www.servicenow.com/docs/4SxEeCMhx42YUiyB7JsBqg)**   
  Autonomous Engineer accepts images, documents, code files, and file types specific to ServiceNow as uploads. Supported formats, size limits, and general guidelines apply when generating apps and metadata.
* **[Autonomous Engineer plan and work item states](https://www.servicenow.com/docs/_G_XpYpkDmENvUMWR1gHig)**   
  Plan and work item states appear during planning and execution. Use this reference to identify where a plan or work item is in the execution process and what action is required.
