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 navigation
- Baking a NavMesh
- Testing agent paths
- Tuning bake parameters
- 搭建导航、烘焙 NavMesh、测试 Agent 路径、调整烘焙参数
NavMesh Skills
Bake / clear NavMesh data, calculate paths, sample positions, and configure NavMeshAgent / NavMeshObstacle components.
Operating Mode
- Approval：查询类 skill（
navmesh_calculate_path/navmesh_sample_position/navmesh_get_settings，源码标SkillMode.SemiAuto）直接执行；变更类（navmesh_bake/navmesh_add_agent/navmesh_set_agent/navmesh_add_obstacle/navmesh_set_obstacle/navmesh_set_area_cost，标SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。 - Auto / Bypass：所有未被禁列表拦截的 skill 直接执行。
- 本模块含 Delete 类 skill：
navmesh_clear标记为SkillOperation.Delete，会被IsForbiddenInSemi静态拦截 —— 仅 Bypass 模式或将其加入 Allowlist 才能调用。 navmesh_bake同步阻塞主线程；大场景可能很慢，调用前提醒用户。
