What it does

Unity Validation is an agent skill from Besty0728/Unity-Skills. Validate project and scene health plus cleanup

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development. The repository describes itself as: AI automation skills specifically designed for Unity. The licence is MIT.

When your agent uses it

Game Development work in your project

Example prompts

“/unity-validation”

Requirements

Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 12a40e4. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unity Validation loads about 2.4k tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 737 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~16
When it runs · the whole SKILL.md, loaded when a task matches: ~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Unity Validation Skills

Maintain project health - find problems, clean up, and validate your Unity project.

Operating Mode

Approval: 只读分析 skill（validate_scene / validate_find_missing_scripts / validate_find_unused_assets / validate_texture_sizes / validate_project_structure / validate_missing_references / validate_mesh_collider_convex / validate_shader_errors，标 SkillMode.SemiAuto）直接执行；含 Delete 的 skill（validate_cleanup_empty_folders 标 Analyze | Delete、validate_fix_missing_scripts 标 Execute | Delete，默认 SkillMode.FullAuto）需用户 grant。
Auto / Bypass: 直接执行。
本模块含 Delete 类高危 skill：validate_cleanup_empty_folders / validate_fix_missing_scripts 一旦 dryRun=false 即真删；它们在 Approval / Auto 下被 IsForbiddenInSemi 自动拦截，仅 Bypass 或 Allowlist 命中可执行。强烈建议先用 dryRun=true 预览。

DO NOT (common hallucinations):

Validation skill routes use the validate_* prefix, not validation_*
validation_run / validation_check do not exist → use specific skills such as validate_scene, validate_project_structure, validate_missing_references
validation_fix does not exist → validation skills report issues; use other modules to fix them
validation_clean does not exist → use cleaner module for cleanup operations

Routing:

For unused/duplicate asset cleanup → use cleaner module
For missing script fix → cleaner_fix_missing_scripts (cleaner module)
For compile errors → debug_check_compilation (debug module)

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['largeTextureCount'] > 0:
    print(f"Warning: {texture_result['largeTextureCount']} 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['fixedCount']} 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['folders'])} 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['assets']:
    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
