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.

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 | $0.00013 | $0.02348 |
| Opus 5 | $0.00006 | $0.01174 |
| Sonnet 5 | $0.00003 | $0.00470 |
| Haiku 4.5 | $0.00001 | $0.00235 |
Grade A, and why
unity-animator 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 4d 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 — 244 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
- Setting up or wiring an Animator
- Adjusting animation state machines
- Driving animation parameters at runtime
- 搭建或连接 Animator、调整动画状态机、运行时驱动动画参数
Unity Animator Skills
Control Unity's Mecanim system — create Animator Controllers, add layers' states / transitions / parameters, assign controllers to GameObjects, set parameters at runtime, and play states.
Operating Mode
- Approval：查询类 skill（
animator_get_parameters/animator_get_info/animator_list_states，源码标SkillMode.SemiAuto）直接执行；其余变更类（create_controller / add_parameter / set_parameter / play / assign_controller / add_state / add_transition，标SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。 - Auto / Bypass：所有 skill 直接执行；Auto 走 AI 自我评估，Bypass 全放行。
- 本模块不含 Delete / PlayMode / Reload / 高危 skill，无 Bypass-only 拦截项。
animator_set_parameter/animator_play作用于场景中已挂 Animator 的 GameObject；如果当前不在 Play mode，状态机只在 Editor 预览模式推进，效果与 runtime 不完全等价。
DO NOT (common hallucinations):
animator_create_clip/animator_add_clipdo not exist → AnimationClips are created via Unity Editor or asset importanimator_set_speeddoes not exist → usecomponent_set_propertyon Animator component with propertyName="speed"
Routing:
- For Timeline animation → use
timelinemodule - For component properties on Animator → use
componentmodule - For animation import settings → use

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-animator is a skill published in the GitHub repository Besty0728/Unity-Skills (1,701 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 2,348 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.
