WHY IT NEEDS A POLICY

Why mixpost_schedule_post needs a policy

Scheduling a post is a reversible write operation that creates a scheduled publishing task. It does not irreversibly delete data (not Destructive), does not execute arbitrary code (not Execute), involves no financial transaction (not Financial), and modifies rather than merely reads state (not Read).

From the tool's definition Tool name explicitly states 'schedule_post' and description confirms it schedules 'a post for publishing'. This creates/modifies scheduled content in the social media management system.
