# CrestApps.Core Document Agents

Four code-defined **system agents** work on files for the primary model. Each is always available to orchestration, hidden from AI Profile and Chat Interaction agent pickers, published through an A2A host, and runs its own hidden tools. The primary model delegates every request that produces or changes that kind of file, and every follow-up ("make the title blue"), to the agent. Base document processing is in `crestapps-core-document-processing`.

| Agent | Name | Registered by | Package |
|---|---|---|---|
| Tabular Data Agent | `tabular-data-agent` | `AddDocumentProcessing()` | `CrestApps.Core.AI.Documents` |
| Presentation Agent | `presentation-agent` | `AddOpenXml()` | `CrestApps.Core.AI.Documents.OpenXml` (agent code in `CrestApps.Core.AI.Documents`) |
| Word Agent | `word-agent` | `AddWord()` | `CrestApps.Core.AI.Documents.Word` |
| PDF Agent | `pdf-agent` | `AddPdf()` on the document-processing builder | `CrestApps.Core.AI.Documents.Pdf` |
