I built a CLI that turns a rough product idea into a SPEC.md for AI coding agents
Hey there,
I built a small CLI tool called quickStart because I kept running into the same problem:
Before an AI coding agent writes any useful code, I usually spend 30–90 minutes explaining the product idea, stack preferences, auth, database, features, deployment, and all the little decisions that should have been written down first.
quickStart is a short interactive interview that turns a rough idea into:
- SPEC.md as the source of truth
- CLAUDE.md / AGENTS.md / Cursor / Windsurf / Copilot / Aider instruction files
- suggested build order
- open questions for the agent
- rough infra cost estimate
I also added a non-technical mode after a friend tried it and had no idea what half the stack/deploy questions meant. In that mode, it asks plain product questions and lets the coding agent propose technical choices later.
Quick install:
npx quickstart-ai

I’d love feedback on two things:
- Are there any questions you’d remove from the interview?
- Would you rather get a shorter SPEC.md, or a more detailed one that gives the coding agent fewer chances to guess?
Not trying to sell anything, just curious if this solves a real annoyance for other people building with coding agents.
Cheers!
