What it does

• 185 Built-in Tools. Scene editing, assets, scripts, Play Mode control, visual evidence, structured inspection, guarded reference edits and bounded verification across 43 modules
• Structured Returns + instanceId Chaining. Tools return {success, message, data} JSON with stable instanceId fields so agents can chain by_id calls reliably instead of re-resolving by name
• IFunplayCommand for execute_code. New snippet template with auto-Undo (ctx.RegisterObjectCreation/Modification/DestroyObject), structured logs (ctx.Log/LogWarning/LogError), and a tracked changelog returned to the agent
• Resources & Prompts. Live project context, scene/selection/error resources, resource templates, and reusable workflow prompts
• Input Simulation + Screenshots. Drive play mode with keyboard/mouse simulation and verify results with game/scene captures. v0.7.2 adds real-frame continuous mouse/single-touch dragging, bounded waiting and owned cleanup; see timing and ba
