Claude Code on OpenRouter — keep the harness, swap in cheaper models

Imagine if you could use Cloud Code for free, because once you hit that limit, it literally stops you mid-built. Here's exactly how to get around that. Go to OpenRouter and create an API key. Then comes the part that most people miss, which is that you need to paste a config prompt into your Cloud setup through something like anti-gravity. That prompt rewires Cloud Code to use OpenRouter instead of Anthropic. And now you've got Cloud Code running with whatever model that you picked, even the free open source ones. You still get the agent loop, and the skills, and the harness that's built around Cloud Code, but you're using a different model, so it's cheaper or potentially free. So if you just want to keep building without burning credits, then comment open and I'll send you the exact config prompt in full setup.
