defmodule PhoenixKitWeb.Live.Modules.AI.Prompts do
@moduledoc """
LiveView for AI prompts management.
This module provides an interface for managing reusable AI prompt templates
with variable substitution support.
## Features
- **Prompt Management**: Add, edit, delete, enable/disable AI prompts
- **Variable Display**: Shows extracted variables from prompt content
- **Usage Tracking**: View usage count and last used time
## Route
This LiveView is mounted at `{prefix}/admin/ai/prompts` and requires
appropriate admin permissions.
