description: Run Unity physics queries and configure physics

> **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_collider` do not exist → use `component_add` with componentType "Rigidbody"/"BoxCollider"/etc.
• `physics_simulate` does 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 `component` module
• For physics material → use `physics_create_material` (this module)
• For layer collision matrix → `physics_set_layer_collision` (this module)
