# Task 6: Screenshots & Final Assets - Implementation Summary
## Overview
This task focused on creating tools and documentation for capturing authentic screenshots of the MCP debugger in action. The key principle was 100% authenticity - all screenshots must come from real debugging sessions with no mock data or staging.
## Files Created
### 1. `examples/visualizer/capture_guide.md`
A comprehensive guide for capturing screenshots that includes:
- Prerequisites and setup instructions
- Exact MCP commands for each screenshot scenario
- What to capture for each of the 4 required screenshots
- OS-specific screenshot tool recommendations
- Troubleshooting tips
### 2. `examples/visualizer/optimize_screenshots.py`
A Python script that:
- Optimizes PNG file sizes for web delivery (target <200KB)
- Creates WebP versions for modern browsers
- Maintains 100% authentic content (only reduces file size)
- Provides detailed optimization statistics
- Includes authenticity verification reminders
### 3. `assets/screenshots/README.md`
Documentation for the screenshots directory that:
- Describes each screenshot with key features
- Provides usage examples for documentation (Markdown and HTML)
- Emphasizes authenticity guarantee
- Includes technical specifications
- Shows expected file organization
## Screenshot Requirements
### 1. **debugging-session.png**
- Shows paused debugging session at breakpoint
- Displays breakpoint marker (●) and current line indicator (→)
- Includes stack trace in tool panel
- Captures real debugpy session via MCP
### 2. **variable-inspection.png**
- Shows the actual bug in swap_vars.py (both variables become 20)
- Displays get_variables response
- Demonstrates real debugging flow
- No mock data - actual bug behavior
### 3. **mcp-integration.png**
- Shows raw MCP protocol communication
- Includes tool:call and tool:response JSON
- Demonstrates actual client-server messages
- No prettifying - authentic protocol data
### 4. **multi-session.png**
- Shows multiple concurrent debug sessions
- Real session IDs and names
- Demonstrates session management
- Each session is a real debugpy instance
## Key Principles Implemented
1. **100% Authenticity**
- No log injection or fake states
- Real debugging sessions only
- Actual bugs and behavior
- Reproducible by anyone
2. **Simplicity**
- Uses OS-native screenshot tools
- Clear step-by-step instructions
- No complex capture scripts needed
3. **Professional Quality**
- Optimization for web delivery
- Consistent dimensions (1200x800)
- WebP alternatives for modern browsers
- Clear documentation
## Usage Instructions
1. **Capture Screenshots**:
```bash
# Terminal 1: Start the system
python examples/visualizer/demo_runner.py
# Terminal 2: Connect MCP client and execute commands
# Use OS screenshot tools to capture at key moments
```
2. **Optimize Files**:
```bash
python examples/visualizer/optimize_screenshots.py
```
3. **Use in Documentation**:
```markdown
*Active debugging session with breakpoint and current line indicators*
```
## Success Criteria Met
- ✅ Created capture guide with exact MCP commands
- ✅ Built optimization tool that preserves authenticity
- ✅ Documented all screenshots with descriptions
- ✅ Emphasized real system demonstration
- ✅ Made process reproducible by anyone
## What Was NOT Created
As per requirements, these were explicitly NOT created:
- ❌ No `setup_screenshot_states.py` - No fake states
- ❌ No log injection scripts - Real logs only
- ❌ No staging or mocking tools
## Next Steps
To complete the screenshot capture:
1. Build the MCP server: `npm run build`
2. Follow the capture guide to take screenshots
3. Save to `assets/screenshots/` with correct names
4. Run optimization script
5. Screenshots ready for release documentation
This approach proves that mcp-debugger is production-ready with real, reproducible functionality that users will experience exactly as shown.
