## Why conv_send_message is rated Medium

This tool creates or modifies conversation records by appending messages. It is reversible (messages can typically be edited or deleted in conversation systems) and has no financial impact. The medium severity reflects that unauthorized message sending could impersonate users, spread misinformation, or damage customer relationships, but the blast radius is limited to the conversation system itself.

From the tool's own definition: "Tool name 'conv_send_message' and description 'Append a message to a conversation' indicate creation/modification of conversation data."

## Use case

AI agents use conv_send_message to create or update resources in Munin, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Munin environment.
