> **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
- Checking runtime performance
- Taking a profiler snapshot
- Inspecting memory/frame stats
- 查看运行时性能、抓取 profiler 快照、检查内存/帧率统计

# Profiler Skills

Get performance statistics.

## Operating Mode

- **Approval / Auto / Bypass**: 所有 skill 直接执行。本模块**全部**标 `ReadOnly = true, Mode = SkillMode.SemiAuto`，三档模式下都不需要 grant。
- **本模块不含 Delete / PlayMode / Reload / RiskLevel=high 类 skill** —— 没有 `IsForbiddenInSemi` 拦截。
- 注：本组 skill 仅做"瞬时快照"读取，不是 Profiler 录制控制；持续采样请用 Unity Profiler 窗口。

**DO NOT** (common hallucinations):
- `profiler_start` / `profiler_stop` do not exist → profiler skills are read-only snapshots, not recording controls
- `profiler_record` does not exist → use Unity Profiler window for recording
- `profiler_analyze` / `profiler_get_fps` do not exist → use `profiler_get_stats` (FPS, batches, draw calls) or `profiler_get_memory` (heap sizes)

**Routing**:
- For scene performance hints → use `perception` module's `scene_performance_hints`
- For memory info → `debug_get_memory_info` (debug module) or `profiler_get_memory` (this module)
- For optimization suggestions → use `optimization` module
