As someone who has stubbornly stuck with Claude Code, what's a good harness for Gemini models?

I resisted at first but now I main antigravity for work. All the software (web, react-native app, client cms platform, postgres backed, multiple ETL systems, a few chat/websocket backends) for my company is loaded into a single project. I spend time writing prompts and forming plans back and forth with the agents then I click GO. Over the past year we've gone from it taking minutes and needing a reasonable amount of back and forth and fixing, to it taking 10-20 seconds and outputting near perfect work within my system accross app/service boundaries.

I highly recommend just getting out of Anthropic's (or anyone's) vendor lock-in. Use opencode or pi. You can still use your subscription pricing using a proxy. I switched to opencode and haven't looked back.

Antigravity is probably the best of the bunch I've tried. I'd say it's pretty comparable to Claude Code (I use both daily).

  • Antigravity which lacks an auto approve mode? Not really comparable to Claude Code when you're looking to run a team of agents from my experience.

    • I've curated my auto-approve list to specific commands by approving them with "always allow in this project" (I never want it e.g. committing/pushing to GitHub, removing files, etc without being in the loop) but Antigravity does have both a standard "auto-approve" mode _and_ a "Turbo mode" which disables ALL approvals of all kinds.

  • Just like Claude Code and others it has the same —-dangerously-skip-permissions flag, auto approves everything

The vscode chat is great. Not sure if it's also called copilot, but you can plug in any models there and they get sandboxed, tools and link to your code. Great stuff.

You can use any model with Claude Code. Most chinese one have a Anthropic compatible endpoint and for Google and OpenAI's models you can get a compatible endpoint with a proxy like Bifrost. No need to change your harness.

Antigravity has been also rapidly improving lately, and your can also use any of the open coding harnesses. But I mostly meant “harness” as in your workflow/loop setup.
