What Works Well

Summer Engine’s AI can do a lot directly in your project: Scene modifications. Add nodes, set properties, connect signals. “Add a CharacterBody2D named Player.” “Set the Button text to ‘Start Game’.” “Connect the Button’s pressed signal to start_game.” Changes appear immediately in the editor. Script operations. Create scripts, attach them to nodes, open your external editor for code. Summer Engine writes production-ready code that integrates with your existing codebase. Asset import. Import 3D models, textures, and audio from Summer Studio. “Import a low-poly tree for my forest.” “Build a village: houses, trees, fences, and props.” Summer Engine searches, downloads, runs the import pipeline, and places assets. Bulk import is supported. Many assets in one batch. Project settings. Change main scene, physics layers, window size. Add input actions (jump, movement, controller mappings). Game systems. Character controllers, inventory systems, AI behaviors, network sync. Summer Engine builds complete systems, not just snippets. All changes go through safe operations with full undo support. Every change can be reverted with Ctrl+Z. Nothing breaks unexpectedly.

​
Current Limitations

No batch code refactors. Large refactors across many files (e.g., rename a function in 50 files) are not supported yet. Bulk asset import is supported; bulk code refactors are not. Limited import settings. Asset import options are mostly manual for now. You may need to adjust import settings in the editor for some assets. Scene-focused. Works best with open scenes rather than project-wide changes. For cross-scene refactors, you may need to do it scene by scene. Shell commands require approval. Summer Engine can propose shell commands (run tests, install deps, run scripts), but nothing executes until you approve it. This is by design. You stay in control.

​
What’s Safe

  • All operations are undoable (Ctrl+Z)
  • Editor APIs only. No direct file manipulation that could corrupt projects
  • Explicit operations. AI must specify exactly what it’s changing
  • Immediate feedback. Changes appear instantly so you can verify

​
Best Practices

Review before applying. The change review panel shows exactly what will be modified. Check it before confirming. Save regularly. Save your scenes after AI makes changes you want to keep. This persists changes to your project files. Use undo freely. Don’t hesitate to undo AI changes that aren’t quite right. You can always ask for a different approach.
