## Overview

The prompt routes (`/api/prompts`) enable users to manage prompts within their mandate. These routes focus on **prompt administration** including creation, editing, and deletion.

**Key Principles:**
- **User-Centric**: Documentation organized around what users want to accomplish
- **Backend-Driven**: All forms, tables, and UI components generated from backend metadata
- **No Hardcoding**: Field definitions, labels, validation rules, and options come from the backend
- **Permission-Aware**: Backend enforces permissions; frontend handles gracefully
- **Mandate-Scoped**: Prompts are managed within the context of mandates
