# Theo · Document Generation

> Theo can produce native PDF, DOCX, XLSX, PPTX, and CSV documents from a single conversational prompt. Content is drafted by a reasoning model, then rendered through format-specific pipelines into a downloadable artifact persisted to object storage.

## At a glance
- Formats: PDF, DOCX, XLSX, PPTX, CSV.
- Triggered automatically by the routing engine when an intent classifier detects a document request, or explicitly by passing a "documentFormat" hint.
- Renders to a permanent URL on object storage. Streaming clients receive the URL in the final artifact event.
- Style guidance: customers can pin a template via skill manifest (cover sheet, header / footer, palette, font stack).

## How a request flows
1. The routing engine inspects the prompt for a document request shape (verb + a format keyword like "report", "spreadsheet", "deck").
2. The orchestrator dispatches to the document mode pipeline.
3. A reasoning model drafts structured content (title, sections, tables, bullets).
4. A format-specific renderer produces the binary asset (React-PDF for PDF, native DOCX / XLSX / PPTX engines).
5. The artifact is uploaded to object storage and surfaced as a download link.

## API
- Endpoint: POST /api/v1/completions with mode "document", or rely on the routing engine to promote a document-shaped prompt.
- Body fields: prompt (required), format (one of pdf / docx / xlsx / pptx / csv; optional, auto-detected from prompt), template (optional skill template id), filename (optional).
- Response: SSE stream emits a document tool run plus a final artifact event with the persistent URL.

## Skills
Document templates can ship as skills. A skill manifest can declare a default template (cover page, header / footer, table styles) so an AI Worker dedicated to invoicing, reporting, or onboarding always produces a branded document. See https://hitheo.ai/llms/skills.txt.
