Update ModelDialog to accept options for model selection and enhance error handling for invalid models. Modify CLI to use the new model configuration and update interrogation command for improved functionality.

Add pricing structure for token usage in CLI and enhance token handling in ModelDialog. Implement cost breakdown per model based on input, cached, and output tokens, and ensure proper initialization of token counts in usage handling.
Refactor CLI and file handling tools for improved functionality. Update CLI interrogation command for better clarity and adjust logging format. Modify list_files.js to enhance path display logic and update read_file.js schema to allow null values for optional parameters, improving flexibility in file reading operations.

+You're on the right track! You want to create a **Roundcube plugin** that allows users to **enhance or rewrite the email body using an LLM**, by sending the current message content to a backend API (your LLM service), then replacing the textarea content with the response.
+
+Here’s a complete working example of such a plugin, called `llm_compose_helper`. It adds a button to the compose screen, sends the current message text to a configured URL via AJAX, and replaces the message body with the LLM-generated result.
+
+---
+
+## ✅ Goal
+- Add a "Rewrite with AI" button in the compose window.
+- On click: open a popup asking the user for a rewrite prompt/instructions.
+- Submit both the current message body and the user prompt to the configured LLM API endpoint.
+- Replace the `<textarea>` content with the returned text.
+
+---
+
+## 📁 Plugin Structure
+```
+plugins/
+  llm_compose_helper/
+    llm_compose_helper.php     <-- Main plugin class
+    config.inc.php             <-- Configuration file
+    localization/en_US.inc     <-- Language labels
+    js/llm_compose_helper.js   <-- Client-side JavaScript
+```
+

+    }
+}
+```
+
+---
+
+## 2. `config.inc.php` – Plugin Configuration
+
+```php
+<?php
+
+// URL of your LLM API endpoint
+$config['llm_api_url'] = 'https://your-llm-api.example.com/rewrite';
+
+// Optional: headers (e.g., auth tokens)
+$config['llm_api_headers'] = array(
+    'Authorization: Bearer your-secret-token',
+    'Content-Type: application/json'
+);
+```
+
+> 💡 You can later override this in `config/config.inc.php` globally.
+
+---
+
+## 3. `localization/en_US.inc`
+
+```php
+<?php
+
+$labels = array(
+    'rewrite_with_llm' => 'Rewrite message with AI',
+    'rewrite_label'    => 'AI Rewrite',
+    'enter_prompt'     => 'Enter rewrite prompt',

+    'rewrite_cancel'   => 'Cancel',
+);
+
+$messages = array(
+    'prompt_placeholder' => 'e.g., Make it shorter and more formal',
+);
+```
+
+> Add other language files like `fr_FR.inc`, `de_DE.inc`, etc., if needed.
+

+
+## 4. `js/llm_compose_helper.js` – Client-Side Logic
+
+```javascript

+## 5. Extend `llm_compose_helper.php` – Add Server-Side Action
+
+Update the `llm_compose_helper.php` file to register the AJAX action and handle the request:

+    ]);
+}
+```
+
+---
+
+## 6. Example LLM API Response Format (Expected)
+
+Your external LLM endpoint should accept POST JSON:
+
+```json
+{ "text": "Hello, I am writing to ask about...", "prompt": "Make it shorter and more formal" }
+```
+
+And return:
+
+```json
+{ "text": "Hi, I hope you're doing well. I'm reaching out to inquire about..." }
+```
+
+Ensure CORS is allowed if hosted separately.
+
+---
+
+## 7. Optional: Add More Labels
+
+In `localization/en_US.inc`, add:
+
+```php
+$messages = array(
+    'rewrite_success' => 'Message rewritten successfully!',
+    'rewrite_error'   => 'Failed to rewrite message.',
+    'non_empty'       => 'Please write something before using AI rewrite.'
+);
+```
+
+---
+
+## 8. Enable the Plugin
+
+In `config/config.inc.php`:
+
+```php
+$config['plugins'] = array(
+    // ... other plugins
+    'llm_compose_helper'
+);
+```
+
+---
+
+## ✅ Final Result
+
+When composing or replying:
+- A new button labeled "AI Rewrite" appears in the toolbar.
+- Clicking it opens a dialog asking for a rewrite prompt.
+- Submitting sends the current message and the prompt to your LLM API.
+- The response replaces the message body.
+- Works with plain text and HTML (via CKEditor if enabled).

 This is a custom utility that makes it more convenient to add, remove, move, or edit code files. 'apply_patch' effectively allows you to execute a diff/patch against a file, 
 but the format of the diff specification is unique to this task, so pay careful attention to these instructions. 
 To use the 'apply_patch' command, you should pass a message of the following structure as "input":

 *** Begin Patch
