name: unity-profiler description: Capture read-only Unity runtime performance snapshots

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
