Spec Driven Development

Most software failures are not caused by a lack of coding ability. They are caused by unclear expectations.

If your requirements are vague, your output will be vague. That was true before AI, and it is even more true now.

Spec Driven Development is the process I use to avoid that trap:

  1. Handwrite a specification that fully defines the work.
  2. Hand that spec to Claude Code or Cursor to execute.
  3. Grade the result against the spec.

That loop sounds simple, but it changes everything.
