- ✅ **Reproducible** - Can regenerate anytime with one command
- ✅ **Authentic** - Captures real terminal output with formatting
- ✅ **Maintainable** - Easy to update when command output changes
- ✅ **Reusable** - Script can generate screenshots for other CLI commands

---

## Implementation Details

### 1. Mock Flag Implementation

**File**: `/Users/abrichr/oa/src/openadapt-ml/openadapt_ml/benchmarks/cli.py`

**Changes**:
- Added `--mock` argument to VM parser (line 6425-6430)
- Modified `vm monitor` action to generate realistic mock data:
  - VM status (IP: 172.171.112.41, Size: Standard_D4ds_v5, State: VM running)
  - Activity (benchmark_running, WAA benchmark ready)
  - Cost tracking (2.5 hours uptime, $0.48 total)
  - Azure ML jobs (2 jobs: completed and running)
  - Evaluation history (2 past runs with success rates)
- Skips dashboard/tunnel logic in mock mode for clean exit

**Usage**:
```bash
# Basic mock output
uv run python -m openadapt_ml.benchmarks.cli vm monitor --mock

# With detailed information
uv run python -m openadapt_ml.benchmarks.cli vm monitor --mock --details
```

### 2. Screenshot Generation Script

**File**: `/Users/abrichr/oa/src/openadapt-ml/scripts/generate_vm_screenshots_simple.py`

**Features**:
- Pure Python solution using PIL (Pillow)
- No external tools required (asciinema/agg not needed)
- Captures terminal output and renders as PNG
- Monaco font rendering with dark terminal theme
- Automatic cleanup
- Progress reporting

**Usage**:
```bash
uv run python scripts/generate_vm_screenshots_simple.py
```

**Output**:
- `docs/screenshots/vm_monitor_dashboard_full.png` (47.1 KB)
- `docs/screenshots/vm_monitor_details.png` (59.5 KB)

### 3. README Documentation

**File**: `/Users/abrichr/oa/src/openadapt-ml/README.md`

**New Section**: § 13.4 VM Monitoring Dashboard (lines 779-823)

**Content**:
- Command examples (basic and --details)
- Two screenshots with descriptive captions
- Feature list (6 key features)
- Mock mode usage
- Auto-shutdown option
- Links to CLAUDE.md and docs/azure_waa_setup.md

## Technical Analysis

### Tool Evaluation Summary

| Tool | Pros | Cons | Verdict |
|------|------|------|---------|
| **asciinema + agg** | ✅ High quality, reproducible | ❌ Requires external tools | ⚠️ Requires installation |
| **termshot** | ✅ One-step, SVG output | ❌ Not ideal for long output | ⚠️ Requires installation |
| **carbon-now-cli** | ✅ Beautiful | ❌ Not for terminal output | ❌ Not suitable |
| **Pure Python + PIL** | ✅ No dependencies, cross-platform | ⚠️ Basic rendering | ✅ **CHOSEN** |
| **Manual screenshots** | ✅ Zero setup | ❌ Not reproducible, costs VM time | ❌ Not ideal |

**Final Choice**: Pure Python + PIL
- Works out of the box (Pillow already installed)
- Cross-platform
- Good enough quality for documentation
- Fast and reliable

### Alternative Scripts Provided

Two scripts created for flexibility:

1. **`generate_vm_screenshots_simple.py`** (USED)
   - Pure Python, no external deps
   - Good quality PNG output
   - Works immediately

2. **`generate_vm_screenshots.py`** (ALTERNATIVE)
   - Uses asciinema + agg (higher quality)
   - Requires: `brew install asciinema agg`
   - Use if better quality needed in future

### Priority 2 (Nice to Have)

3. **Improve screenshot rendering**
   - Better font rendering (use actual Monaco.ttf)
   - Support ANSI color codes
   - Variable-width fonts for non-code text

4. **Animated GIFs**
   - Show dashboard updating over time
   - Requires asciinema or similar

## Maintenance Guidelines

### Updating Screenshots

When VM monitor output changes:

1. Verify mock data is still representative:
   ```bash
   uv run python -m openadapt_ml.benchmarks.cli vm monitor --mock
   ```

2. Regenerate screenshots:
   ```bash
   uv run python scripts/generate_vm_screenshots_simple.py
   ```

3. Review screenshots in `docs/screenshots/`

4. Update README captions if needed

5. Commit changes:
   ```bash
   git add docs/screenshots/*.png README.md
   git commit -m "docs: update VM monitor screenshots"
   ```

### Adding New Screenshots

To capture other CLI commands:

1. Add `--mock` flag to the command (if not present)
2. Add entry to `generate_vm_screenshots_simple.py`:
   ```python
   generate_screenshot(
       ["uv", "run", "python", "-m", "openadapt_ml.benchmarks.cli", "vm", "your-command", "--mock"],
       "vm_your_command",
       title="Your Command",
   )
   ```
3. Run script to generate
4. Update README with new screenshot

## Lessons Learned

### What Worked Well

1. **Mock data approach** - Eliminated VM dependency completely
2. **Pure Python** - No external tool installation hassles
3. **Incremental testing** - Tested mock mode before screenshot generation
4. **Clear documentation** - Analysis document helps future work

### What Could Be Improved

1. **Font rendering** - PIL's text rendering is basic (but acceptable)
2. **Color support** - ANSI colors not preserved (but not critical)
3. **Automation** - Could add pre-commit hook to auto-regenerate

### Key Takeaways

1. **Always consider mock data** - Saves time and money
2. **Start with simplest solution** - Pure Python worked fine
3. **Document the "why"** - Analysis document is valuable
4. **Make it reproducible** - One-command regeneration is crucial
