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。

Unity Perception Skills
Use this module for read-only scene and project analysis.
Operating Mode
- Approval / Auto / Bypass: 本模块所有 skill（
scene_analyze/scene_summarize/scene_health_check/scene_component_stats/scene_find_hotspots/scene_tag_layer_stats/scene_performance_hints/scene_diff/hierarchy_describe/scene_context/scene_dependency_analyze/scene_spatial_query/scene_materials/scene_contract_validate/project_stack_detect/script_analyze/script_dependency_graph/scene_export_report）都标Mode = SkillMode.SemiAuto，三档模式下直接执行无需 grant。其中前 17 个同时标ReadOnly = true。 - 特别说明：
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

DO NOT (common hallucinations):
perception_analyze,perception_scan, andperception_describedo not existscene_contextis noteditor_get_context: it exports hierarchy/components/references, while editor context focuses on current editor statescene_analyze,scene_health_check,scene_contract_validate,scene_component_stats,scene_find_hotspots, andproject_stack_detectbelong to this module even if the prefix looks likescene_*orproject_*
Routing:

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 |

VerifiedTrustedCommunity
Keyword research and validation with real search-demand data — never ship keywords from intuition alone. Probes Google Autocomplete per language (free, no account) to prove demand and discover the exact phrasing people type, checks SERPs for winnability, and uses Keyword Planner/Ahrefs/Semrush exports when the user has access. Activates when: choosing or reviewing SEO keywords, meta keywords, page titles, article topics or slugs, landing page copy targeting search, App Store/ASO keyword fields, multilingual keyword sets, 'what should we rank for', 'keyword analysis', or auditing why a page doesn't rank. Also invoke it as a validation pass whenever another skill or task produces a keyword list.
