Wiring AI Agents to Legacy Databases: Lessons in Constraint Engineering
An engineer connects a coding agent to a legacy PHP app and MySQL database with write access, discovering a real bug but also the risk of unrestricted permissions. The article details four layers of constraints to limit blast radius, including disposable databases and read-only access. It argues that grounding AI in actual schemas improves accuracy but demands careful security engineering.
