WHY IT NEEDS A POLICY

Why agregarClaveForanea needs a policy

Adding a foreign key constraint modifies the database schema by creating a new referential integrity constraint between tables. This is a reversible schema change (the foreign key can be dropped later), placing it in the Write category. Sibling tools like 'eliminarClaveForanea' (remove foreign key) confirm this is reversible.

From the tool's definition Tool name 'agregarClaveForanea' means 'add foreign key' in Spanish. The description instructs to follow rules for adding a foreign key constraint.
