Skills

validate_scene

Comprehensive scene validation.

Parameter	Type	Required	Default	Description
`checkMissingScripts`	bool	No	true	Check for missing scripts

`checkDuplicateNames`	bool	No	false	Check duplicate names

Returns: {success, sceneName, totalIssues, missingScripts, missingPrefabs, duplicateNames}

validate_find_missing_scripts

Find objects with missing script references.

Parameter	Type	Required	Default	Description
`searchInPrefabs`	bool	No	false	Also check prefab assets

Returns: {success, count, objectsWithMissingScripts: [{name, path, missingCount}]}

validate_fix_missing_scripts

Remove missing script components.

Parameter	Type	Required	Default	Description
`dryRun`	bool	No	true	Preview only, don't remove

Returns: {success, totalFixed, fixedObjects}

validate_cleanup_empty_folders

Remove empty folders from project.

Parameter	Type	Required	Default	Description
`rootPath`	string	No	"Assets"	Starting folder
`dryRun`	bool	No	true	Preview only, don't delete

Returns: {success, count, foldersToDelete: [path]}

validate_find_unused_assets

Find potentially unused assets.

Parameter	Type	Required	Default	Description
`assetType`	string	No	null	Filter: Texture/Material/Prefab/etc
`limit`	int	No	100	Max results

Returns: {success, count, unusedAssets: [path]}

validate_texture_sizes

Check for oversized textures.

Parameter	Type	Required	Default	Description
`maxRecommendedSize`	int	No	2048	Warn if larger
`limit`	int	No	50	Max results

Returns: {success, totalChecked, oversizedCount, oversizedTextures: [{path, width, height, recommendation}]}

validate_project_structure

Get project folder structure overview.

Parameter	Type	Required	Default	Description
`rootPath`	string	No	"Assets"	Starting folder
`maxDepth`	int	No	3	Max folder depth

Returns: {success, structure, summary: {totalFolders, totalAssets}}

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

•Always use dryRun=True first to preview changes
•Run validation before major builds
•Review unused assets manually before deletion
•Keep texture sizes appropriate for target platform
•Fix missing scripts before they cause runtime errors
•Regular cleanup prevents project bloat
