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 | $0.00011 | $0.02241 |
| Opus 5 | $0.00005 | $0.01120 |
| Sonnet 5 | $0.00002 | $0.00448 |
| Haiku 4.5 | $0.00001 | $0.00224 |
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 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 — 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 (1,698 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 2,241 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.
