## Why clickup_create_chat_message_reaction is rated Medium

Adding a reaction is a write operation that creates new data (the reaction record) in a reversible manner. Users can remove reactions if needed, making it non-destructive. The blast radius is minimal as reactions are metadata annotations without affecting task data, timeline, or team operations. Classified as Write rather than Read because it modifies system state by creating a new entity.

From the tool's own definition: "Tool name contains 'create' and description states 'Add a reaction to a message in a chat channel.' This creates a new reaction object/record in the ClickUp system."
