Self-optimizing AI review prompts — an Antigravity 2.0 boilerplate template

Hi everyone :waving_hand:

I wanted to share something I’ve been building with Antigravity 2.0 that I think might be useful to other vibe coders here.

Quick backstory: I coded professionally 20+ years ago, then stopped. I recently came back to build a full-stack app — but this time I don’t write code. I command it. Antigravity is my IDE, Gemini and Claude are my engineering team, and I just set the direction.

Along the way, I developed a workflow infrastructure that I’ve extracted into a reusable template. The key innovation is meta-prompting — prompts that analyze your live codebase and generate context-aware review prompts automatically.

What’s in the template

  • Meta-prompts (docs/prompts/_meta/) that scan your package.json files, GEMINI.md rules, .skills/ directories, and MCP server config to generate hyper-specific code review, spring cleaning, and architecture review prompts

  • Modular skills (.skills/) — domain-specific runbooks the AI loads lazily instead of bloating every conversation’s context

  • Slash-command workflows (.agent/workflows/) — /code-review, /spring-cleaning, /architecture-review, /run-meta-prompts, and more

  • Report retention — timestamped reports with archival policies so the AI reads its own history and doesn’t re-flag resolved issues

  • Dual-model implementation review — Gemini reviews the plan as architect, Claude stress-tests it as pragmatist

  • Gemini Gems integration — a consolidate_docs.ps1 script that merges all .md files so you can upload them to a Gem and ask your repo questions from the Google Gemini app on your phone :mobile_phone:

Fair warning: I haven’t published anything to GitHub since before Git existed (I’m a CVS/SVN era survivor :t_rex:). If I’ve committed some open-source faux pas, I’d genuinely appreciate a heads-up.

This template was extracted from a production app I’m building entirely with Antigravity, and I’m close to releasing it. I’m sharing because I think my approach — as a non-developer doing vibe coding — might offer a different perspective than what experienced developers would build. Sometimes not knowing “the right way” leads to interesting solutions.

Feedback, suggestions, and PRs welcome!

If you check GitHub - GoogleChrome/modern-web-guidance · GitHub maybe you can structure/package it as an Antigravity Plugin so users can:

agy plugin install https://github.com/ThMoJe/antigravity-vibe-template

I’ll definitely have a look at that.

Thanks
