## Common Workflows

### Pre-Build Check
```python
import unity_skills

# Validate scene
scene_result = unity_skills.call_skill("validate_scene")
if scene_result['totalIssues'] > 0:
    print(f"Warning: {scene_result['totalIssues']} issues found")

# Check texture sizes
texture_result = unity_skills.call_skill("validate_texture_sizes", maxRecommendedSize=2048)
if texture_result['oversizedCount'] > 0:
    print(f"Warning: {texture_result['oversizedCount']} oversized textures")
```

### Project Cleanup
```python
import unity_skills

# 1. Preview missing scripts fix
preview = unity_skills.call_skill("validate_fix_missing_scripts", dryRun=True)
print(f"Would fix {preview['totalFixed']} objects")

# 2. Actually fix (if preview looks good)
unity_skills.call_skill("validate_fix_missing_scripts", dryRun=False)

# 3. Preview empty folder cleanup
preview = unity_skills.call_skill("validate_cleanup_empty_folders", dryRun=True)
print(f"Would delete {len(preview['foldersToDelete'])} folders")

# 4. Actually cleanup
unity_skills.call_skill("validate_cleanup_empty_folders", dryRun=False)

# 5. Review unused assets (manual review recommended)
unused = unity_skills.call_skill("validate_find_unused_assets")
for asset in unused['unusedAssets']:
    print(f"Potentially unused: {asset}")
```

## Best Practices

1. **Always use `dryRun=True` first** to preview changes
2. Run validation before major builds
3. Review unused assets manually before deletion
4. Keep texture sizes appropriate for target platform
5. Fix missing scripts before they cause runtime errors
6. Regular cleanup prevents project bloat
