WHY IT NEEDS A POLICY

Why botbell_create_bot needs a policy

This tool creates a new notification bot, which is a reversible write operation. While it doesn't directly send notifications or delete data, it establishes new bot entities that could be used to spam or harass users through the BotBell app. The severity is medium rather than high because the blast radius is limited to bot creation itself—actual notification spam would require the separate botbell_send tool.

From the tool's definition Tool description states "Create a new bot in BotBell," indicating data creation. Returns a bot_id for subsequent use, confirming persistent state modification.
