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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00015 | $0.02168 |
| Opus 5 | $0.00008 | $0.01084 |
| Sonnet 5 | $0.00003 | $0.00434 |
| Haiku 4.5 | $0.00002 | $0.00217 |
Grade A, and why
unity-perception 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 3d 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 — 159 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.

- Gathering context before editing
- Understanding unfamiliar scene/project
- Auditing structure without changes
- 编辑前收集上下文、理解陌生场景或项目、在不改动的前提下审查结构

Operating Mode
- Approval / Auto / Bypass: 本模块 18 个 skill 里有 17 个标
Mode = SkillMode.SemiAuto，三档模式下直接执行无需 grant。其中 16 个是纯读（ReadOnly = true）：scene_analyze/scene_summarize/scene_health_check/scene_component_stats/scene_find_hotspots/scene_tag_layer_stats/scene_performance_hints/scene_diff/hierarchy_describe/scene_context/scene_spatial_query/scene_materials/scene_contract_validate/project_stack_detect/script_analyze/script_dependency_graph。 scene_dependency_analyze是第 17 个 SemiAuto，但它不是纯读：传savePath会Directory.CreateDirectory+File.WriteAllText+ImportAsset落一个新工程资产，所以它标MutatesAssets = true而不再标ReadOnly。仍然无需 grant，但它会进 router 的 diff 捕获，schema/flags 里也会带mutatesAssets—— 不传savePath时才真的什么都不写。- 特别说明：
scene_export_report写 markdown 文件到磁盘（Operation = Analyze | Execute，标MutatesAssets = true），因此不是 SemiAuto——它走默认SkillMode.FullAuto，Approval 模式下需要 grant 才能执行。 - 本模块不含 Delete / PlayMode / Reload / RiskLevel=high 类 skill —— 没有

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-perception is a skill published in the GitHub repository Besty0728/Unity-Skills (1,698 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 2,168 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 2026-08-30.
