WHY IT NEEDS A POLICY

Why update_bio needs a policy

This tool modifies user-controlled profile data (biography text) but does not delete, execute external code, move money, or trigger irreversible actions. The change is easily reversible by updating the bio again. The blast radius is minimal—a misused bio update would merely alter visible profile text, which is low-impact and recoverable. This is a clear Write operation.

From the tool's definition Tool name is 'update_bio' and description states 'Update your Instagram profile biography' — a reversible modification of profile metadata with a 150-character limit.
