version: "1.0.3" name: unity-optimization description: Optimize project assets and scenes

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

• Reducing build size
• Batch-compressing assets
• Analyzing scene poly/material usage
• 缩减包体、批量压缩资源、分析场景面数与材质用量

Optimization Skills

Optimize project assets (Textures, Models).

Operating Mode

• Approval: 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

Skills

optimize_textures

Optimize texture settings (maxSize, compression). Returns list of modified textures.

Returns: { success, count, message, modified }

optimize_mesh_compression

Set mesh compression for 3D models.

Returns: { success, count, compression, modified }

optimize_analyze_scene

Analyze scene for performance bottlenecks (high-poly meshes, excessive materials).

Returns: { success, totalRenderers, totalTriangles, totalMaterialSlots, issueCount, issues }

optimize_find_large_assets

Find assets exceeding a size threshold (in KB).

Returns: { success, threshold, count, assets }

optimize_set_static_flags

Set static flags on GameObjects. flags: Everything/Nothing/BatchingStatic/OccludeeStatic/OccluderStatic/NavigationStatic/ReflectionProbeStatic

Returns: { success, gameObject, flags, affectedCount }

optimize_get_static_flags

Get static flags of a GameObject.

Returns: { success, gameObject, flags, isStatic }

optimize_audio_compression

Batch set audio compression. compressionFormat: PCM/Vorbis/ADPCM. loadType: DecompressOnLoad/CompressedInMemory/Streaming

Returns: { success, count, compressionFormat, loadType, modified }

optimize_find_duplicate_materials

Find materials with identical shader and properties.

Returns: { success, duplicateGroups, groups }

optimize_analyze_overdraw

Analyze transparent objects that may cause overdraw.

Returns: { success, transparentObjectCount, objects }

optimize_set_lod_group

Add or configure LOD Group. lodDistances: comma-separated screen-relative heights (e.g. '0.6,0.3,0.1')

Returns: { success, gameObject, lodLevels, distances }
