Use case · legacy modernization
Modernize legacy code with AI agents, one reviewable step at a time.
The free Spec Kitty CLI turns a legacy rewrite into small, specced, reviewed steps your team can schedule. It is the free part of Spec Kitty; Brain Kitty and Team Kitty add your team's standards over MCP.
What changes for legacy work
Keep what customers rely on
Before anything changes, the CLI asks what the system does today and what must stay intact, and turns the answers into acceptance criteria.
Technical debt you can schedule
A large modernization goal becomes ordered work packages, each small enough to review, that your team can prioritize like any other work.
Leadership sees why it changed
When someone asks why a behavior changed, the spec, decisions and reviews are written down.
Start with one module.
Bring the system to a 30-minute call; we'll say plainly whether Spec Kitty fits.
