# TASK-014-3: Scene Inspect Object Tool

**Status:** ✅ Done  
**Priority:** 🔴 High  
**Phase:** Phase 7 - Introspection & Listing APIs  
**Completion Date:** 2025-11-27

## 🎯 Objective
Deliver a deep inspection tool that returns structured data about a single object: type, transform, polycount, materials, modifiers, and custom metadata. This replaces unreliable visual inspection and is foundational for every later introspection tool.

## 🏗️ Architecture Requirements
### 1. Domain Layer (`server/domain/tools/scene.py`)
- Extend `ISceneTool` with `inspect_object(name: str) -> Dict[str, Any]` returning structured data (type, transforms, collections, materials, modifiers, mesh stats, custom props).

### 2. Application Layer (`server/application/tool_handlers/scene_handler.py`)
- Handler validates RPC response for `scene.inspect_object` and returns the dict for adapters to format.

### 3. Adapter Layer (`server/adapters/mcp/server.py`)
- Add `scene_inspect_object(ctx: Context, name: str) -> str` with docstring describing sections and actionable errors (suggesting `scene_list_objects` when missing).

### 4. Blender Addon API (`blender_addon/application/handlers/scene.py`)
- Gather info without mode switching; try `obj.evaluated_get(depsgraph)` for mesh stats after modifiers.
- Return dict including: `object_name`, `type`, transforms, `dimensions`, `collections`, `material_slots`, `modifiers`, `mesh_stats` (verts/edges/faces/triangles), `custom_properties`.

### 5. RPC Server (`blender_addon/__init__.py`)
- Register `scene.inspect_object` endpoint.

## ✅ Deliverables
- Domain interface, models, and accompanying exceptions (if not already defined).
- Application handler + DI binding.
- MCP adapter entry with clear formatting.
- Blender API + RPC registration.
- Documentation + changelog updates, README Phase 7 checklist.

## 🧪 Testing
- Inspect Mesh with modifiers/materials.
- Inspect non-mesh (Camera/Light) to ensure graceful handling of mesh stats.
- Invalid name -> user-friendly error.

## 📚 References
- `_docs/TOOLS_ARCHITECTURE_DEEP_DIVE.md`
- `README.md` Phase 7 scope description.

## ✅ Completion Notes
- Extended `ISceneTool`/`SceneToolHandler` with `inspect_object`, maintaining single scene interface per Clean Architecture rules.
- Implemented Blender addon logic (transform data, collections, modifiers, material slots, optional mesh stats, custom props) and registered the RPC endpoint.
- Added new MCP tool formatting multi-section summaries plus actionable error guidance.
- Updated README, `_docs` knowledge base, task board, and changelog.
- Added handler/unit tests (`tests/test_scene_mode.py`, `tests/test_scene_get_mode_handler.py`) and ran `PYTHONPATH=. poetry run pytest`.
