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 | $0.00011 | $0.02279 |
| Opus 5.5 | $0.00004 | $0.00912 |
| Sonnet 5.5 | $0.00002 | $0.00456 |
| Haiku 4.5 | $0.00001 | $0.00228 |
Grade A, and why
unity-physics 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 19d 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.
Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 205 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
- Casting rays
- Testing overlaps
- Querying colliders
- Adjusting gravity/physics settings
- 发射射线、检测重叠、查询碰撞体、调整重力/物理设置
Physics Skills
Editor-time physics queries (raycast / overlap), gravity, PhysicMaterial assets, and layer collision matrix.
Operating Mode
- Approval：查询类 skill（
physics_raycast/physics_check_overlap/physics_get_gravity/physics_get_layer_collision等，源码标SkillMode.SemiAuto）直接执行；变更类（physics_set_gravity/physics_create_material/physics_set_material/physics_set_layer_collision，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。
- 注意：所有 skill 都在编辑器线程同步运行。真实物理模拟（积分、碰撞响应）仅在 Play mode 下推进；本模块只做单帧 query + 资产/全局设置写入，不会启动模拟。
DO NOT (common hallucinations):
physics_add_rigidbody/physics_add_colliderdo not exist → usecomponent_addwith componentType "Rigidbody"/"BoxCollider"/etc.physics_simulatedoes not exist → physics simulation runs during Play mode; this module does not step the simulation- Raycast results use world-space coordinates
Routing:
- For adding physics components → use
componentmodule - For physics material → use
physics_create_material(this module) - For layer collision matrix →
physics_set_layer_collision(this module)
Skills
physics_raycast
Cast a ray and get hit info. Parameters:
originX,originY,originZ(float): Origin point.dirX,dirY,dirZ(float): Direction vector.maxDistance(float, optional): Max distance (default 1000).layerMask(int, optional): Layer mask (default -1).
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-physics is a skill published in the GitHub repository Besty0728/Unity-Skills (1,878 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 2,279 once invoked, about $0.0000 per session on Opus 5.5. 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.
