UnitySkills is a REST API-based automation engine that lets AI coding agents control Unity Editor projects, including scenes and other editor operations. It is for developers using Unity with supported coding agents and IDEs. The catalogue skills and commands provide the agent workflows used to operate Unity projects through the engine.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.02222 |
| Opus 5 | $0.00005 | $0.01111 |
| Sonnet 5 | $0.00002 | $0.00444 |
| Haiku 4.5 | $0.00001 | $0.00222 |
Grade A, and why
unity-validation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Triggers
- Checking broken or missing references
- Validating scene/project integrity
- Cleaning up before a build
- 检查断裂或丢失引用、校验场景/项目完整性、构建前清理
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, notvalidation_* validation_run/validation_checkdo not exist → use specific skills such asvalidate_scene,validate_project_structure,validate_missing_referencesvalidation_fixdoes not exist → validation skills report issues; use other modules to fix themvalidation_cleandoes not exist → usecleanermodule for cleanup operations
Routing:
- For unused/duplicate asset cleanup → use
cleanermodule - For missing script fix →
cleaner_fix_missing_scripts(cleaner module) - For compile errors →
debug_check_compilation(debug module)
Skills Overview
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

unity-validation is a skill published in the GitHub repository Besty0728/Unity-Skills (1,723 stars, last pushed today), licensed MIT. It adds 10 tokens to every session and 2,222 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
