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 | $0.00015 | $0.05224 |
| Opus 5 | $0.00008 | $0.02612 |
| Sonnet 5 | $0.00003 | $0.01045 |
| Haiku 4.5 | $0.00002 | $0.00522 |
Grade A, and why
unity-uitoolkit 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 6d 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 — 277 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
- Authoring runtime or editor UI with UI Toolkit
- Writing USS/UXML
- Wiring a UIDocument
- Binding UI to data
- Building world-space UI
- 用 UI Toolkit 编写运行时或编辑器 UI、编写 USS/UXML、接入 UIDocument、把 UI 绑定到数据源、做世界空间 UI
Unity UI Toolkit Skills
Use this module for Unity UI Toolkit only: UXML for structure, USS for styling, UIDocument for scene attachment, and PanelSettings for runtime rendering.
Requires Unity 2022.3+. Do not mix this module with
ui_*UGUI/Canvas skills. Localization: Match visible UI text to the user's language. Chinese conversation -> Chinese labels/placeholders/button text. USS class names and CSS variables stay English.
Operating Mode
- Approval：查询类 skill（
uitk_read_file/uitk_find_files/uitk_get_panel_settings/uitk_list_documents/uitk_inspect_uxml/uitk_list_uss_variables/uitk_inspect_document/uitk_runtime_binding_list/uitk_worldspace_panel_get/uitk_element_reference_get，源码标SkillMode.SemiAuto）直接执行；其余文件/场景写入类（uitk_create_*/uitk_write_file/uitk_add_*/uitk_modify_element/uitk_runtime_binding_add/uitk_uxml_upgrade/uitk_worldspace_panel_create等，标SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。 - Auto / Bypass：未被禁列表拦截的 skill 直接执行。
- 本模块含 Delete 类 skill：
uitk_delete_file、uitk_remove_element、uitk_remove_uss_rule标记为SkillOperation.Delete，被IsForbiddenInSemi静态拦截 —— 仅 Bypass 模式或加入 Allowlist 才能调用。 - 本模块另含 2 个域重载类 skill：
uitk_create_editor_window与uitk_create_runtime_ui会生成.cs文件、必然触发域重载，因此标MayTriggerReload = true。IsForbiddenInSemi直读这个 flag，所以它们和上面的 Delete 类同样被静态拦截 —— Approval 与 Auto 下都返MODE_FORBIDDEN，且这不是"需 grant"、grant 也给不了，仅 Bypass 或命中 Allowlist 才能调用。这两个是上面第一条"其余写入类需用户 grant"的例外。 - 同一个 flag 还有第二个后果：
?mode=transactional的批量链里含这两步，会在执行前被 400 拒绝，错误点名违规的steps[i]。原因是域重载会清空编辑器 undo 栈，事务批量的回滚承诺无法兑现，所以服务端选择前置拒绝而不是事后失败。要在事务批量的流程里生成脚本，把这两步拆出去单独调用。 - Asset 重导行为：所有写文件/删文件 skill 通过
AssetDatabase.ImportAsset(path)对单个 USS/UXML 资产单独触发导入，不会调AssetDatabase.Refresh()触发全项目扫描；批量创建依次单独 Import。但 USS/UXML 是 ScriptedImporter 类型，Import 仍会重建依赖此资产的 PanelSettings/UIDocument 引用，触发 IMGUI 检查器刷新与场景视图重绘。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-uitoolkit is a skill published in the GitHub repository Besty0728/Unity-Skills (1,727 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 5,224 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.
