Optimization Skills

Optimize project assets (Textures, Models).

Operating Mode

• Approval(默认): 只读分析类 skill（optimize_analyze_scene / optimize_find_large_assets / optimize_get_static_flags / optimize_find_duplicate_materials / optimize_analyze_overdraw，标 SkillMode.SemiAuto）直接执行；写型 skill（optimize_textures / optimize_mesh_compression / optimize_audio_compression / optimize_set_static_flags / optimize_set_lod_group，默认 SkillMode.FullAuto）需用户 grant，grant 后一步执行返结果。
• Auto / Bypass: 直接执行。
• 本模块不含 Delete / PlayMode / Reload / RiskLevel=high 类 skill —— 写型 skill 改的是 Importer / 组件设置，会重新导入资源，但不会触发 Domain Reload，也不会被 IsForbiddenInSemi 拦截。批量操作前务必检查筛选范围（filter / assetType），改完无 dry-run 回滚。

DO NOT (common hallucinations):

• optimize_scene / optimization_run do not exist → use specific skills: optimize_analyze_scene, optimize_find_large_assets, optimize_find_duplicate_materials, etc.
• optimize_compress / optimize_compress_textures / optimize_compress_meshes / optimize_compress_audio do not exist → use optimize_textures (textures), optimize_mesh_compression (meshes), optimize_audio_compression (audio)
• optimize_set_lod / optimize_setup_lod do not exist → use optimize_set_lod_group
• Optimization skills are analysis + action tools — always review results before applying batch changes

Routing:

• For profiler metrics → use profiler module
• For static batching flags → optimize_set_static_flags (this module)
• For performance review guidance → load performance advisory module
