+# Agent Roles
+
+Agent Roles allow you to define different AI personas with specialized system prompts for various tasks. Switch between roles instantly in the chat interface to adapt the AI's behavior to your current needs.
+
+## Overview
+
+Agent Roles are reusable system prompt configurations that modify how the AI assistant responds. Instead of manually changing system prompts, you can create roles like "Developer", "Code Reviewer", or "Documentation Writer" and switch between them with a single click.
+
+**Key Features:**
+- **Quick Switching**: Change roles from the chat toolbar dropdown
+- **Custom Prompts**: Each role has its own specialized system prompt
+- **Built-in Roles**: Pre-configured Developer and Code Reviewer roles
+- **Persistent**: Roles are saved locally and loaded on startup
+- **Extensible**: Create unlimited custom roles for different tasks
+
+## Default Roles
+
+QodeAssist comes with three built-in roles:
+
+### Developer
+Experienced Qt/C++ developer with a structured workflow: analyze the problem, propose a solution, wait for approval, then implement. Best for implementation tasks where you want thoughtful, minimal code changes.
+
+### Code Reviewer
+Expert C++/QML code reviewer specializing in C++20 and Qt6. Checks for bugs, memory leaks, thread safety, Qt patterns, and production readiness. Provides direct, specific feedback with code examples.
+
+### Researcher
+Research-oriented developer who investigates problems and explores solutions. Analyzes problems, presents multiple approaches with trade-offs, and recommends the best option. Does not write implementation code — focuses on helping you make informed decisions.
+
+## Using Agent Roles
+
+### Switching Roles in Chat
+
+1. Open the Chat Assistant (side panel, bottom panel, or popup window)
+2. Locate the **Role selector** dropdown in the top toolbar (next to the configuration selector)
+3. Select a role from the dropdown
+4. The AI will now use the selected role's system prompt
+
+**Note**: Selecting "No Role" uses only the base system prompt without role specialization.
+
+### Viewing Active Role
+
+Click the **Context** button (📋) in the chat toolbar to view:
+- Base system prompt
+- Current agent role and its system prompt
+- Active project rules
+
+## Managing Agent Roles
+
+### Opening the Role Manager
+
+Navigate to: `Qt Creator → Preferences → QodeAssist → Chat Assistant`
+
+Scroll down to the **Agent Roles** section where you can manage all your roles.
+
+### Creating a New Role
+
+1. Click **Add...** button
+2. Fill in the role details:
+   - **Name**: Display name shown in the dropdown (e.g., "Documentation Writer")
+   - **ID**: Unique identifier for the role file (e.g., "doc_writer")
+   - **Description**: Brief explanation of the role's purpose
+   - **System Prompt**: The specialized instructions for this role
+3. Click **OK** to save
+
+### Editing a Role
+
+1. Select a role from the list
+2. Click **Edit...** or double-click the role
+3. Modify the fields as needed
+4. Click **OK** to save changes
+
+**Note**: Built-in roles cannot be edited directly. Duplicate them to create a modifiable copy.
+
+### Duplicating a Role
+
+1. Select a role to duplicate
+2. Click **Duplicate...**
+3. Modify the copy as needed
+4. Click **OK** to save as a new role
+
+### Deleting a Role
+
+1. Select a custom role (built-in roles cannot be deleted)
+2. Click **Delete**
+3. Confirm deletion
+
+## Creating Effective Roles
+
+### System Prompt Tips
+
+- **Be specific**: Clearly define the role's expertise and focus areas
+- **Set expectations**: Describe the desired response format and style
+- **Include guidelines**: Add specific rules or constraints for responses
+- **Use structured prompts**: Break down complex roles into bullet points
+
+## Storage Location
+
+Agent roles are stored as JSON files in:
+
+```
+~/.config/QtProject/qtcreator/qodeassist/agent_roles/
+```
+
+**On different platforms:**
+- **Linux**: `~/.config/QtProject/qtcreator/qodeassist/agent_roles/`
+- **macOS**: `~/Library/Application Support/QtProject/Qt Creator/qodeassist/agent_roles/`
+- **Windows**: `%APPDATA%\QtProject\qtcreator\qodeassist\agent_roles\`
+
+### File Format
+
+Each role is stored as a JSON file named `{id}.json`:
+
+```json
+{
+    "id": "doc_writer",
+    "name": "Documentation Writer",
+    "description": "Technical documentation and code comments",
+    "systemPrompt": "You are a technical documentation specialist...",
+    "isBuiltin": false
+}
+```
+
+### Manual Editing
+
+You can:
+- Edit JSON files directly in any text editor
+- Copy role files between machines
+- Share roles with team members
+- Version control your roles
+- Click **Open Roles Folder...** to quickly access the directory
+
+## How Roles Work
+
+When a role is selected, the final system prompt is composed as:
+
+```
+┌─────────────────────────────────────────────────┐
+│ Final System Prompt = Base Prompt + Role Prompt │
+├─────────────────────────────────────────────────┤
+│ 1. Base System Prompt (from Chat Settings)      │
+│ 2. Agent Role System Prompt                     │
+│ 3. Project Rules (common/ + chat/)              │
+│ 4. Linked Files Context                         │
+└─────────────────────────────────────────────────┘
+```
+
+This allows roles to augment rather than replace your base configuration.
+
+## Best Practices
+
+1. **Keep roles focused**: Each role should have a clear, specific purpose
+2. **Use descriptive names**: Make it easy to identify roles at a glance
+3. **Test your prompts**: Verify roles produce the expected behavior
+4. **Iterate and improve**: Refine prompts based on AI responses
+5. **Share with team**: Export and share useful roles with colleagues
+
+## Troubleshooting
+
+### Role Not Appearing in Dropdown
+- Restart Qt Creator after adding roles manually
+- Check JSON file format validity
+- Verify file is in the correct directory
+
+### Role Behavior Not as Expected
+- Review the system prompt for clarity
+- Check if base system prompt conflicts with role prompt
+- Try a more specific or detailed prompt

+# Chat Summarization
+
+Chat Summarization allows you to compress long conversations into concise AI-generated summaries. This helps save context tokens and makes it easier to continue work on complex topics without losing important information.
+
+## Overview
+
+When conversations grow long, they consume more context tokens with each message. Chat Summarization uses your configured Chat Assistant provider to create an intelligent summary that preserves:
+
+- Key decisions and conclusions
+- Technical details and code references
+- Important context for continuing the conversation
+
+**Key Features:**
+- **One-click compression**: Summarize directly from the chat toolbar
+- **Preserves original**: Creates a new chat file, keeping the original intact
+- **Smart summaries**: AI extracts the most relevant information
+- **Markdown formatted**: Summaries are well-structured and readable
+
+## Using Chat Summarization
+
+### Compressing a Chat
+
+1. Open any chat with conversation history
+2. Click the **Compress** button (📦) in the chat top bar
+3. Wait for the AI to generate the summary
+4. A new chat opens with the compressed summary
+
+### What Gets Preserved
+
+The summarization process:
+- Maintains chronological flow of the discussion
+- Keeps technical details, code snippets, and file references
+- Preserves key decisions and conclusions
+- Aims for 30-40% of the original conversation length
+
+### What Gets Filtered
+
+The following message types are excluded from summarization:
+- Tool call results (file reads, searches)
+- File edit blocks
+- Thinking/reasoning blocks
+
+## How It Works
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│                    CHAT SUMMARIZATION                       │
+├─────────────────────────────────────────────────────────────┤
+│  1. Original chat messages are collected                    │
+│  2. Tool/thinking messages are filtered out                 │
+│  3. AI generates a structured summary                       │
+│  4. New chat file is created with summary as first message  │
+│  5. Original chat remains unchanged                         │
+└─────────────────────────────────────────────────────────────┘
+```
+
+### File Naming
+
+Compressed chats are saved with a unique suffix:
+```
+original_chat.json → original_chat_a1b2c.json
+```
+
+Both files appear in your chat history, allowing you to switch between the full conversation and the summary.
+
+## Best Practices
+
+1. **Summarize at natural breakpoints**: Compress after completing a major task or topic
+2. **Review the summary**: Ensure important details were captured before continuing
+3. **Keep originals**: Don't delete original chats until you've verified the summary is sufficient
+4. **Use for long sessions**: Most beneficial for conversations with 20+ messages
+
+## When to Use
+
+**Good candidates for summarization:**
+- Long debugging sessions with resolved issues
+- Feature implementation discussions with final decisions
+- Research conversations where conclusions were reached
+- Any chat approaching context limits
+
+**Consider keeping full history for:**
+- Ongoing work that may need exact message references
+- Conversations with important code snippets you'll copy
+- Discussions where the reasoning process matters
+
+## Configuration
+
+Chat Summarization uses your current Chat Assistant settings:
+- **Provider**: Same as Chat Assistant (Settings → QodeAssist → General)
+- **Model**: Same as Chat Assistant
+- **Template**: Same as Chat Assistant
+
+No additional configuration is required.
+
+## Troubleshooting
+
+### Compression Button Not Visible
+- Ensure you have an active chat with messages
+- Check that the chat top bar is visible
+
+### Compression Fails
+- Verify your Chat Assistant provider is configured correctly
+- Check network connectivity
+- Ensure the model supports chat completions
+
+### Summary Missing Details
+- The AI aims for 30-40% compression; some details may be condensed
+- For critical information, keep the original chat
+- Consider summarizing smaller conversation segments

 You're all set! QodeAssist is now ready to use in Qt Creator.
 
+## Extended Thinking Mode
+
+Ollama supports extended thinking mode for models that are capable of deep reasoning (such as DeepSeek-R1, QwQ, and similar reasoning models). This mode allows the model to show its step-by-step reasoning process before providing the final answer.
+
+### How to Enable
+
+**For Chat Assistant:**
+1. Navigate to Qt Creator > Preferences > QodeAssist > Chat Assistant
+2. In the "Extended Thinking (Claude, Ollama)" section, check "Enable extended thinking mode"
+3. Select a reasoning-capable model (e.g., deepseek-r1:8b, qwq:32b)
+4. Click Apply
+
+**For Quick Refactoring:**
+1. Navigate to Qt Creator > Preferences > QodeAssist > Quick Refactor
+2. Check "Enable Thinking Mode"
+3. Configure thinking budget and max tokens as needed
+4. Click Apply
+
+### Supported Models
+
+Thinking mode works best with models specifically designed for reasoning:
+- **DeepSeek-R1** series (deepseek-r1:8b, deepseek-r1:14b, deepseek-r1:32b)
+- **QwQ** series (qwq:32b)
+- Other models trained for chain-of-thought reasoning
+
+### How It Works
+
+When thinking mode is enabled:
+1. The model generates internal reasoning (visible in the chat as "Thinking" blocks)
+2. After reasoning, it provides the final answer
+3. You can collapse/expand thinking blocks to focus on the final answer
+4. Temperature is automatically set to 1.0 for optimal reasoning performance
+
+**Technical Details:**
+- Thinking mode adds the `enable_thinking: true` parameter to requests sent to Ollama
+- This is natively supported by the Ollama API for compatible models
+- Works in both Chat Assistant and Quick Refactoring contexts

+## Chat History Migration
+
+### Images not showing in old chats (version 0.5.x → 0.6.x)
+
+If you have chat histories from QodeAssist version 0.5.x or earlier, images may not display correctly due to a storage structure change.
+
+**Solution:** Rename the content folder for each affected chat:
+
+```bash
+# Navigate to your chat history folder
+cd ~/path/to/chat_history
+
+# For each chat file, rename its folder
+mv chat_name_images chat_name_content
+```
+
+**Example:**
+```bash
+mv my_conversation_2024-11-28_images my_conversation_2024-11-28_content
+```
+
+**What changed:**
+- Old format (v0.1): Stored files in `chat_name_images/`
+- New format (v0.2): Stores all content in `chat_name_content/` (both images and text files)

+ * REFERENCE: Item Types in List Input Items Response
+ * ===================================================
+ * 
+ * The `data` array in ListInputItemsResponse can contain various item types.
+ * This file serves as a reference for all possible item types.
+ * 
+ * EXISTING TYPES (already implemented):
+ * -------------------------------------
+ * - MessageOutput (in ResponseObject.hpp)
+ * - FunctionCall (in ResponseObject.hpp)
+ * - ReasoningOutput (in ResponseObject.hpp)
+ * - FileSearchCall (in ResponseObject.hpp)
+ * - CodeInterpreterCall (in ResponseObject.hpp)
+ * - Message (in ModelRequest.hpp) - for input messages
+ * 
+ * ADDITIONAL TYPES (to be implemented if needed):
+ * -----------------------------------------------
+ * 
+ * 1. Computer Tool Call (computer_call)
+ *    - Computer use tool for UI automation
+ *    - Properties: action, call_id, id, pending_safety_checks, status, type
+ *    - Actions: click, double_click, drag, keypress, move, screenshot, scroll, type, wait
+ * 
+ * 2. Computer Tool Call Output (computer_call_output)
+ *    - Output from computer tool
+ *    - Properties: call_id, id, output, type, acknowledged_safety_checks, status
+ * 
+ * 3. Web Search Tool Call (web_search_call)
+ *    - Web search results
+ *    - Properties: action, id, status, type
+ *    - Actions: search, open_page, find
+ * 
+ * 4. Image Generation Call (image_generation_call)
+ *    - AI image generation request
+ *    - Properties: id, result (base64), status, type
+ * 
+ * 5. Local Shell Call (local_shell_call)
+ *    - Execute shell commands locally
+ *    - Properties: action (exec), call_id, id, status, type
+ *    - Action properties: command, env, timeout_ms, user, working_directory
+ * 
+ * 6. Local Shell Call Output (local_shell_call_output)
+ *    - Output from local shell execution
+ *    - Properties: id, output (JSON string), type, status
+ * 
+ * 7. Shell Tool Call (shell_call)
+ *    - Managed shell environment execution
+ *    - Properties: action, call_id, id, status, type, created_by
+ * 
+ * 8. Shell Call Output (shell_call_output)
+ *    - Output from shell tool
+ *    - Properties: call_id, id, max_output_length, output (array), type, created_by
+ *    - Output chunks: outcome (exit/timeout), stderr, stdout
+ * 
+ * 9. Apply Patch Tool Call (apply_patch_call)
+ *    - File diff operations
+ *    - Properties: call_id, id, operation, status, type, created_by
+ *    - Operations: create_file, delete_file, update_file
+ * 
+ * 10. Apply Patch Tool Call Output (apply_patch_call_output)
+ *     - Output from patch operations
+ *     - Properties: call_id, id, status, type, created_by, output
+ * 
+ * 11. MCP List Tools (mcp_list_tools)
+ *     - List of tools from MCP server
+ *     - Properties: id, server_label, tools (array), type, error
+ * 
+ * 12. MCP Approval Request (mcp_approval_request)
+ *     - Request for human approval
+ *     - Properties: arguments, id, name, server_label, type
+ * 
+ * 13. MCP Approval Response (mcp_approval_response)
+ *     - Response to approval request
+ *     - Properties: approval_request_id, approve (bool), id, type, reason
+ * 
+ * 14. MCP Tool Call (mcp_call)
+ *     - Tool invocation on MCP server

+ * 17. Item Reference (item_reference)
+ *     - Internal reference to another item
+ *     - Properties: id, type
+ * 
+ * USAGE:
+ * ------
+ * When parsing ListInputItemsResponse.data array:
+ * 1. Check item["type"] field
+ * 2. Use appropriate parser based on type
+ * 3. For existing types, use ResponseObject.hpp or ModelRequest.hpp
+ * 4. For additional types, implement parsers as needed
+ * 
+ * EXAMPLE:
+ * --------
+ * for (const auto &itemValue : response.data) {
+ *     const QJsonObject itemObj = itemValue.toObject();
+ *     const QString type = itemObj["type"].toString();
+ *     
+ *     if (type == "message") {
+ *         // Use MessageOutput or Message
+ *     } else if (type == "function_call") {
+ *         // Use FunctionCall
+ *     } else if (type == "computer_call") {
+ *         // Implement ComputerCall parser
+ *     }
+ *     // ... handle other types
+ * }
