unity-perception
GitHub提供Unity场景、项目及脚本的只读分析能力，用于AI编码前收集上下文。涵盖结构分析、技术栈探测、健康检查及热点定位等，辅助理解陌生项目或审查结构，不执行修改操作。
Trigger Scenarios
用户要求分析场景结构
用户希望了解项目技术栈
进行代码编辑前的上下文收集
对陌生场景或项目进行审计

"description": "Read-only scene, project, and script analysis for AI coding context — analyze scene structure, detect the project stack, run health checks, and find hotspots. Use when gathering context before editing, understanding an unfamiliar scene or project, or auditing structure without making changes, even if the user just says \"分析一下场景\" or \"看看项目结构\". 只读的场景\/项目\/脚本分析,为 AI 编码提供上下文(分析场景结构、探测项目技术栈、健康检查、定位热点);当用户要在编辑前收集上下文、理解陌生场景或项目、或在不改动的前提下审查结构时使用。"

Operating Mode
- Approval / Auto / Bypass: 本模块所有 skill（

scene_export_report写 markdown 文件到磁盘（Operation = Analyze | Execute，未标ReadOnly），但仍标了SkillMode.SemiAuto，Approval 模式可直接执行。 - 本模块不含 Delete / PlayMode / Reload / RiskLevel=high 类 skill —— 没有

High-Frequency Skill Differences
scene_summarize vs scene_analyze vs scene_health_check
| Skill | Best for | Typical output focus |
|---|---|---|
scene_summarize |
Fast overview | object counts, hierarchy depth, top components |

Hygiene / red flags | missing scripts, duplicate names, deep hierarchy, empty nodes, hotspot-style findings |
scene_context vs hierarchy_describe
| Skill | Best for | Output style |
|---|---|---|
hierarchy_describe |

Key Return Shapes
scene_summarize
Returns sceneName, stats, and optional topComponents.
scene_analyze
Returns summary, stats, findings, warnings, recommendations, and suggestedNextSkills.
scene_health_check
Returns summary, findings, hotspots, and suggestedNextSkills.
scene_context
Returns a structured export with objects, references, and optional codeDependencies. Use it when another AI step needs full scene context, not just a human summary.
High-frequency options:
rootPathto export only one subtreeincludeValues=truewhen serialized field values matterincludeCodeDeps=truewhen AI needs a rough scene-to-code dependency picture
scene_export_report
Writes a markdown artifact to disk and returns savedTo, object/script/reference counts, and success state. Prefer this when the user wants a durable report file.
Defaults:
savePath = "Assets/Docs/SceneReport.md"maxDepth = 10maxObjects = 500
When to Use Which Skill
| Need | Best first skill |
|---|---|

| Suspicious hierarchy or clutter | scene_find_hotspots |
| Safe-to-delete / impact question | scene_dependency_analyze |
| AI coding context export | scene_context |
| Script reading order | script_dependency_graph |
| Render/input/UI stack detection | project_stack_detect |
