A connection is not an integration design
Connecting a model to a database may make a prototype possible. It does not establish which records may be read, which operations are safe, or how failures should be handled. The application’s operating rules still matter.
Expose a deliberate interface
An API can make approved actions explicit, validate input, enforce authorization, and produce an audit trail. Modernization can begin with a narrow interface around a useful workflow rather than a replacement of the entire application.
Preserve the business rules
Review validation, approval, exception handling, and transaction boundaries before introducing agent access. Rules embedded in an older screen or manual process may not exist at the database layer.
Migrate in a controlled scope
Define the workflow, allowed actions, verification scenarios, and recovery process. Separate AI-assisted software development from AI-enabled functionality: using a coding assistant does not mean the resulting system contains an agent.
