SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Before editing a Unity project, AI agents and developers often lack reliable context about scene structure, project stack, and script dependencies, leading to blind edits and broken references. This Skill provides read-only analysis of scenes, hierarchies, components, materials, and scripts so changes are made with full structural awareness. ## Core Features & Use Cases - Scene Analysis & Health Checks: Summarize scenes, detect deep hierarchies, empty nodes, missing scripts, and duplicate names with scene_analyze, scene_health_check, and scene_find_hotspots. - Context Export & Reports: Export structured hierarchy, components, and references via scene_context, or save a durable markdown report with scene_export_report. - Project & Script Insight: Detect render pipeline, input, UI, and packages with project_stack_detect, and map script dependency closures with script_dependency_graph. - Use Case: Before refactoring a MonoBehaviour, run script_dependency_graph to see every script affected, then use scene_dependency_analyze to check which scene objects reference it. ## Quick Start Ask the AI to analyze the current Unity scene and report any health issues, hotspots, and the detected project stack before making changes.

Frequently Asked Questions about unity-perception

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I analyze a Unity scene structure before editing?▼

Use scene_analyze for a combined diagnosis with findings and recommendations, or scene_summarize for a quick overview of object counts, hierarchy depth, and top components. Both are read-only and safe to run in any mode.

How to find script dependencies in a Unity project?▼

Use script_dependency_graph with a script class name to get an N-hop dependency closure showing which scripts must change together. For scene object references instead of code, use scene_dependency_analyze.

What is the difference between scene_summarize, scene_analyze, and scene_health_check?▼

scene_summarize gives a fast overview of counts and top components, scene_analyze provides broad diagnosis with warnings and next-step hints, and scene_health_check focuses on hygiene issues like missing scripts, duplicate names, and empty nodes.

Can these Unity analysis skills modify my scene?▼

No. Seventeen of the eighteen skills are marked ReadOnly, covering analysis, health checks, and context export. The only exception, scene_export_report, writes a markdown report file to disk but never alters scene objects.

How do I detect which render pipeline and packages a Unity project uses?▼

Run project_stack_detect with no parameters. It reports the render pipeline, input system, UI framework, installed packages, test setup, and folder conventions of the project.

When should I use scene_context instead of hierarchy_describe?▼

Use hierarchy_describe for a lightweight human-readable text tree. Use scene_context when another AI step needs structured hierarchy, components, references, and optional code dependencies as machine-consumable context.
