## Why conv_set_subject is rated Medium

This tool modifies conversation metadata (subject) but does not delete data or execute external operations. It is reversible via subsequent set operations. Within the Munin customer platform context, modifying conversation subjects has moderate blast radius—a malicious agent could alter conversation context or mislead users—but does not cause permanent loss or financial impact.

From the tool's own definition: "Tool name 'conv_set_subject' combined with description 'Set a conversation' indicates modification of conversation data. The verb 'set' implies creating or updating a property (likely the subject line) of an existing conversation resource."

## Use case

AI agents use conv_set_subject 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.

## Recommended policy (PolicyLayer)
