```bash
python3 ~/clawd/skills/ppt-compress/scripts/compress.py <pptx_file_path> [output_directory]
```

## Examples

```bash
# Compress PPT and convert to PDF
python3 ~/clawd/skills/ppt-compress/scripts/compress.py "/path/to/file.pptx"

# Specify output directory
python3 ~/clawd/skills/ppt-compress/scripts/compress.py "/path/to/file.pptx" "/Users/xxx/Downloads"
```
