Successful Rules to work better with Unity MCP

[insanetheta]

Hi Folks,

I've been playing around with this MCP in VSCode with Copilot (Claude Sonnet 4) for the last few days, trying to build a simple card game from scratch using a Design Doc I provided. I was quite frustrated with the Model continually breaking compilation or spinning on the same issues then declaring everything working until I added 2 rules to my copilot rules file:

• Always check the console for any compiler errors and fix them before completing the request
• Ensure the unity editor is not in play mode when editing objects
• After C# script changes, ensure the code has finished recompiling before further work within the Unity Editor

Adding these rules has made the agentic process more fruitful.
Are there any rules you've adopted to improve Model performance?
