Limits on the AI FDE Agent.

  • The AI FDE Agent does not write to GP. Access is read-only and provisioned by your team.
  • The AI FDE Agent does not make business decisions. Options are presented to your team and the selection is recorded.
  • The AI FDE Agent does not deploy to production on its own authority. Each production step requires passing checks and your approval.
  • The AI FDE Agent does not resolve uncertainty by assumption. Low-confidence findings go to a Comostasis engineer or become a question for your team.

Start with an assessment of your GP environment.

The assessment is priced up front and capped. It produces the inventory and the fixed migration quote.
