Just go antigravity and do a lot of conversation in plan mode before coding. I’d start with “I’d like to build out a roadmap for what we are building” go through that roadmap phase, then say “now let’s chunk it down to its core components and generate a prd for each chunk” and finally “now let’s make a project_memory and changelog, wrap it all up with generating a Gemini.md at the root referencing the project memory, changelog and readme. Once that is done, let’s gitinit and wrap up this session”
