+#### Completion Trigger Modes
+
+QodeAssist offers two trigger modes for code completion:
+
+**Hint-based**
+- Shows a hint indicator near cursor when you type 3+ characters
+- Press **Space** (or custom key) to request completion
+- **Best for**: Paid APIs (Claude, OpenAI), conscious control
+- **Benefits**: No unexpected API charges, full control over requests, no workflow interruption
+- **Visual**: Clear indicator shows when completion is ready
+
+**Automatic(Default)**
+- Automatically requests completion after typing threshold
+- Works immediately without additional keypresses
+- **Best for**: Local models (Ollama, llama.cpp), maximum automation
+- **Benefits**: Hands-free experience, instant suggestions
+
+💡 **Tip**: Start with Hint-based to avoid unexpected costs. Switch to Automatic if using free local models.
+
+Configure in: `Tools → Options → QodeAssist → Code Completion → General Settings`
+
 ### Chat Assistant
 - Multiple chat panels: side panel, bottom panel, and popup window
 - Chat history with auto-save and restore
 - Token usage monitoring
+- **[Agent Roles](docs/agent-roles.md)** - Switch between AI personas (Developer, Reviewer, custom roles)
+- **[Chat Summarization](docs/chat-summarization.md)** - Compress long conversations into AI-generated summaries
 - **[File Context](docs/file-context.md)** - Attach or link files for better context
 - Automatic syncing with open editor files (optional)
 - Extended thinking mode (Claude, other providers in plan) - Enable deeper reasoning for complex tasks
 
 ### Quick Refactoring

+
+### Key Points
+
+- **Project Rules** are automatically loaded from `.qodeassist/rules/` directory structure
+- **System Prompts** are configured independently for each feature in Settings
+- **Agent Roles** add role-specific prompts on top of the base system prompt (Chat only)
+- **FIM vs Non-FIM models** for code completion use different System Prompts:
+  - FIM models: Direct completion prompt
+  - Non-FIM models: Prompt includes response formatting instructions
+- **Quick Refactor** has its own provider/model configuration, independent from Chat
+- **Custom Instructions** provide reusable templates that can be augmented with specific details
+- **Tool Calling** is available for Chat and Quick Refactor when enabled
+
+See [Project Rules Documentation](docs/project-rules.md), [Agent Roles Guide](docs/agent-roles.md), and [Quick Refactoring Guide](docs/quick-refactoring.md) for more details.

+# 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

 # Quick Refactoring Feature
 
+Quick Refactoring provides AI-assisted code improvements directly in your editor. Select code, press the hotkey, and get instant refactoring suggestions.
+
+## Overview
+
+Quick Refactoring provides AI-assisted code refactoring with its own dedicated provider and model configuration, allowing you to use different settings than your Chat Assistant. You can use built-in quick actions or create your own custom instructions library.
+
 ## Setup
 
-Since this is actually a small chat with redirected output, the main settings of the provider, model and template are taken from the chat settings.
+Quick Refactoring has independent configuration separate from Chat Assistant:
 
-## Using
+### Provider & Model Configuration
 
-The request to model consist of instructions to model, selection code and cursor position.
+Configure provider and model in: `Qt Creator → Preferences → QodeAssist → General Settings`
 
-The default instruction is: "Refactor the code to improve its quality and maintainability." and sending if text field is empty.
+Under the **Quick Refactor** section, you can set:
+- **Provider**: Choose from Ollama, Claude, OpenAI, Google AI, etc.
+- **Model**: Select the specific model for refactoring tasks
+- **Template**: Choose the chat template for this provider
+- **URL**: Set the API endpoint
+- **API Key**: Configure authentication (for cloud providers)
 
-Also there buttons to quick call instractions:
-- Repeat latest instruction, will activate after sending first request in QtCreator session
-- Improve current selection code
-- Suggestion alternative variant of selection code
-- Other instructions[TBD]
+This allows you to:
+- Use a faster/cheaper model for refactoring than for chat
+- Use a local model for refactoring and cloud model for chat
+- Optimize costs by using different providers for different tasks
+
+### Quick Refactor Settings
+
+Additional refactoring-specific options in: `Qt Creator → Preferences → QodeAssist → Quick Refactor`
+
+Configure:
+- **Context Settings**: How much code context to send
+  - Read full file or N lines before/after selection
+- **LLM Parameters**: Temperature, max tokens, top_p, top_k
+- **Advanced Options**: Penalties, context window size
+- **Features**: Tool calling, extended thinking mode
+- **System Prompt**: Customize the base prompt for refactoring
+- **How quick refactor looks**: Display type and sizes
+
+## Using Quick Refactoring
+
+### Basic Usage
+
+1. **Select Code** (or place cursor for line-level refactoring)
+2. **Trigger Quick Refactor**: Press `Ctrl+Alt+R` (Windows/Linux) or `⌥⌘R` (macOS)
+3. **Choose Action**:
+   - Use a built-in quick action button
+   - Select a custom instruction from the dropdown
+   - Type your own instruction
+4. **Get Results**: AI generates refactored code directly replacing your selection
+
+### Quick Action Buttons
+
+The dialog provides three built-in quick actions:
+
+| Button | Description |
+|--------|-------------|
+| **Repeat Last** | Reuses the last instruction from your session (enabled after first use) |
+| **Improve Code** | Enhances readability, efficiency, and maintainability with best practices |
+| **Alternative Solution** | Suggests different implementation approaches and patterns |
+
+## Custom Instructions
+
+### Overview
+
+Custom Instructions allow you to create a reusable library of refactoring templates. Instead of typing the same instructions repeatedly, save them once and access them instantly through the searchable dropdown.
+
+**Key Features:**
+- **Quick Access**: Search and select instructions by typing
+- **Flexible**: Use as-is or add extra details for each use
+- **Manageable**: Easy create, edit, and delete interface
+- **Persistent**: Instructions saved locally and loaded on startup
+- **Accessible**: Direct access to instruction files folder
+
+### Creating Custom Instructions
+
+1. Click the **`+`** button in the Quick Refactor dialog
+2. Fill in the form:
+   - **Name**: Short descriptive title (e.g., "Add Documentation")
+   - **Instruction Body**: Detailed prompt for the LLM
+
+**Example instruction:**
+
+```
+Name: Add Documentation
+Body: Add comprehensive documentation to the selected code or code afer cursor following: 
+      Doxygen style. Include parameter descriptions, return value 
+      documentation, and usage examples where applicable.
+```
+
+
+### Using Custom Instructions
+
+#### Method 1: Select and Use
+1. Open Quick Refactor dialog (`Ctrl+Alt+R` / `⌥⌘R`)
+2. Click the dropdown or start typing instruction name
+3. Select instruction (autocomplete will help)
+4. Optionally add extra details in the text field below
+5. Press OK
+
+
+#### Method 2: Search by Typing
+1. Open Quick Refactor dialog
+2. Start typing in the instruction dropdown (e.g., "doc...")
+3. Autocomplete shows matching instructions
+4. Select with arrow keys or click
+5. Add optional details and execute
+
+**Search Features:**
+- Case-insensitive search
+- Match anywhere in instruction name
+- Keyboard navigation (arrow keys, Enter)
+- Instant filtering as you type
+
+### Combining Instructions with Additional Details
+
+Custom instructions serve as **base templates** that you can augment with specific requirements:
+
+**Example 1 - Use instruction as-is:**
+```
+Selected: "Add Documentation"
+Additional text: [empty]
+→ Sends: "Add comprehensive documentation..."
+```
+
+**Example 2 - Add specific requirements:**
+```
+Selected: "Optimize Performance"  
+Additional text: "Focus on reducing memory allocations"
+→ Sends: "Optimize Performance instructions... 
+
+Focus on reducing memory allocations"
+```
+
+This approach allows maximum flexibility while maintaining a clean instruction library.
+
+### Managing Custom Instructions
+
+The Quick Refactor dialog provides full CRUD operations:
+
+| Button | Action | Description |
+|--------|--------|-------------|
+| **+** | Add | Create new custom instruction |
+| **✎** | Edit | Modify selected instruction |
+| **−** | Delete | Remove selected instruction (with confirmation) |
+| **📁** | Open Folder | Open instructions directory in file manager |
+
+**Edit/Delete:**
+- Select an instruction from dropdown (or type its name)
+- Click Edit (✎) or Delete (−) button
+- Confirm changes
+
+<!-- PLACEHOLDER_IMAGE: Screenshot showing instruction management buttons -->
+
+### Storage Location
+
+Custom instructions are stored as JSON files in:
+
+```
+~/.config/QtProject/qtcreator/qodeassist/quick_refactor/instructions/
+```
+
+**File Naming Format:**
+```
+Instruction_Name_with_underscores_{unique-uuid}.json
+```
+
+**Examples:**
+```
+Add_Documentation_a7f3c92d-8e4b-4f1a-9c0e-1d2f3a4b5c6d.json
+Optimize_Performance_3b8e4f9a-7c2d-4e1b-8f3a-9c1d2e3f4a5b.json
+Fix_Code_Style_c5d6e7f8-9a0b-1c2d-3e4f-5a6b7c8d9e0f.json
+```
+
+**File Format:**
+```json
+{
+    "id": "unique-uuid",
+    "name": "Add Documentation",
+    "body": "Add comprehensive documentation...",
+    "version": "0.1"
+}
+```
+
+### Backup and Sharing
+
+Since instructions are simple JSON files, you can:
+
+1. **Backup**: Copy the instructions directory
+2. **Share**: Share JSON files with team members
+3. **Version Control**: Add to your dotfiles repository
+4. **Edit Manually**: Modify JSON files directly if needed
+
+Click the **📁** button to quickly open the instructions folder in your file manager.
+
+## Context and Scope
+
+### What Gets Sent to the LLM
+
+The LLM receives:
+- **Selected Code** (or current line if no selection)
+- **Context**: Surrounding code (configurable amount)
+- **File Information**: Language, file path
+- **Cursor Position**: Marked with `<cursor>` tag
+- **Selection Markers**: `<selection_start>` and `<selection_end>` tags
+- **Your Instructions**: Built-in, custom, or typed
+- **Project Rules**: If configured (see [Project Rules](project-rules.md))
+
+### Context Configuration
+
+Configure context amount in: `Qt Creator → Preferences → QodeAssist → Quick Refactor`
+
+Options:
+- **Read Full File**: Send entire file as context

+
+### 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
