Cut to the smallest version
Every feature is something to design, build and fix forever. Start with the smallest version that solves the problem. Real users will tell you what comes next.
In the Claude app, click + New. Check that your project folder is selected, and set the mode to Plan.
Click Copy, paste into the prompt box and press Enter.
Read docs/product.md. List every feature this app could have, and sort them into Version 1, Later and Not doing.
Version 1 is the smallest version that solves the core problem for one kind of person. For anything I want to keep in it, ask what breaks if we leave it out. Add the lists to docs/product.md.Answer Claude's questions one at a time. Short answers are fine, and "I don't know" is a good answer. Claude will suggest options.
Read the plan Claude shows you. To change it, keep planning and type what you'd change. When it looks right, approve it, and choose Yes when Claude asks to make changes. Claude adds the lists to your document.
Click docs/product.md in the chat to read it. If something's wrong, tell Claude what to change.
