Critical failures across naming, descriptions, and schema quality. Tool 1 (manage_ai_tools) violates single-responsibility principle with 30+ enum actions crammed into one tool, making it impossible for LLMs to reason about intent. Descriptions are generic and lack actionable guidance. Tool 2 (manage_tool_groups) has minimal description (67 chars) and vague parameter descriptions. Neither tool documents output schemas. No error handling guidance. No parameter validation rules stated. The 'action' enum pattern is an anti-pattern, each action should be a separate tool (e.g., smart_uv_unwrap, auto_retopology, etc.). Baseline: 90% of A+ tools have 50-200 char descriptions with clear WHAT/WHEN/WHY; these fail that bar.

• Split manage_ai_tools into 10+ separate tools: smart_uv_unwrap, auto_retopology, smart_decimate, ai_material_suggest, smart_lighting, auto_rig_suggest, smart_bevel, intelligent_merge, auto_collider, auto_lod_generate, smart_cleanup. Each tool name should start with a verb and reflect a single action. Remove EXPLAIN_*, DRY_RUN_*, CONFIDENCE_* variants, make those separate tools (e.g., explain_smart_uv_unwrap, dry_run_smart_uv_unwrap) or parameters on the main tool.
• Document output schemas for all tools. Example for smart_uv_unwrap: {success: boolean, message: string, uv_islands: number, seams_created: number, object_id: string}. Include all fields the agent needs for downstream calls.
• Expand manage_ai_tools description to 100-150 chars explaining WHAT it does, WHEN to use it (e.g., 'Call when you need to optimize mesh topology for game export'), and WHAT it returns. Example: 'Automatically unwraps UV coordinates for the target mesh. Returns success status, number of UV islands created, and the modified object ID. Use when preparing models for texturing or game export.'
• Add descriptions to all manage_tool_groups parameters. Example: group_name: 'Name of the tool group (e.g., SCENE_SETUP, MODELING_WORKFLOW, MATERIALS, CHARACTER, ANIMATION, RENDERING, GAME_EXPORT, PHYSICS, AI_EXTERNAL). Call LIST_GROUPS to see all available groups.' query: 'Free-text search term to find tools by name or keyword (e.g., "uv unwrap", "retopology").'
• Add error handling guidance. Document what happens if the mesh is invalid, if Blender is not running, if the operation times out. Provide recovery steps: 'If retopology fails due to invalid topology, try smart_cleanup first, then retry.' Include timeout and retry limits.
