SovereignSpec

A local-first specification operating system for AI-assisted development.

The problem

When an agent writes code from a prose request, the specification is implicit and therefore unverifiable. Making the specification an artifact — versioned, reviewable, executable — is what makes the resulting code checkable against something.

How it works

  1. 01Treat the spec as the primary artifact and the code as a derived one.
  2. 02Keep the whole loop local so specifications and their implementations stay on the machine that owns them.
  3. 03Gate implementation on an approved specification rather than on a prompt.
