How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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)
