RISK

Why discord_create_guild_emoji is rated Medium

This tool creates (writes) new data in the Discord server by adding an emoji resource. It is reversible through deletion, so it does not qualify as Destructive. The blast radius is low because emoji creation has no impact on members, permissions, or critical server functions—it only adds a cosmetic asset that can be easily removed.

From the tool's definition Tool creates a new guild emoji resource from image data. The description explicitly states 'Create a guild emoji from base64 image data URL', indicating irreversible creation of a new emoji asset.
