PMs and architects before the repo exists

The spec-to-prototype stack

Claude turns a PRD into contracts, Eraser draws the topology, v0 scaffolds the UI. Not a Cursor repo map.

Who owns what

  1. Claude

    The spec — entities, APIs, acceptance notes. Not the diagram and not the Next app.

    Try Claude (opens in a new tab)
  2. Eraser

    The topology — ER and cloud boxes from that markdown. Not frontend code.

    Try Eraser (opens in a new tab)
  3. v0

    The UI scaffold — screens from the spec. Not the database schema.

    Try v0 (opens in a new tab)

How to use this stack

  1. Paste the PRD into Claude. Get entities, routes, and what is explicitly out of scope.
  2. Eraser compiles that into a map you can put on the ticket. This is not Archify on a git graph.
  3. v0 (or Bolt.new) scaffolds the first screens from the same spec.
  4. A human decides what gets a repo. Cursor and Claude Code start after this, not instead of it.
