WHY IT NEEDS A POLICY

Why airtable_set_table_schema needs a policy

Setting a table schema modifies the table structure and field definitions, which is a write operation that alters the database structure. While reversible (can be changed again), it affects all records in the table and has potential for significant unintended consequences if an AI agent applies incorrect schemas—potentially breaking record compatibility, losing type information, or causing cascading validation…

From the tool's definition Tool name 'set_table_schema' and description states it 'Set[s] the schema for a table' which modifies the structural definition of a table. This is a reversible modification to data structure/metadata rather than deletion.
