Especially interested in people using AI for brownfield development, but generally interested in if people are continuing down the spec driven path, or if agents + skills/prompts/mcp/agents.md/something else is filling the niche spec driven development was trying to capture.
Question was prompted by seeing spec kit have no commits for over a month an no obvious integration with GitHub’s new agents integration.
Every new project (cloud consulting + app dev), I feed in the contract, transcripts of my discovery sessions, my labeled architecture diagram, transcript of the design review discussion and any other artifacts.
First I have to create Epics and stories anyway for the PMO even if I am working on it by myself.
Then I ask ChatGPT what the phases should be, I tweak it , break it down, give it more details, etc
Finally, I ask it to give me unrendered markdown with the details and a checklist and that’s the starting point of my repo.
As I’m using Codex (I never seem to hit limits with my $20 a month plan) and Claude (better at troubleshooting), I tell them to update my document with what’s done, guidance I’ve given it etc.
I treat both of them like junior devs and keep my hands on the wheel and test and verify each phase.
Yes I know I’m fortunate that all of my work is greenfield -> empty repo and empty AWS account that I ask the client for.
