What conversations_rename does on Slack
AI agents use conversations_rename to create or update resources in Slack, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Slack environment.
Why conversations_rename is rated Medium
Renaming a conversation modifies existing data (the channel name) but the change is reversible—it can be renamed again. This is a Write operation, not Destructive. Severity is medium because renaming channels could cause confusion in a workspace if done maliciously or carelessly, but the impact is limited to metadata and easily corrected. Confidence is high because the intent is unambiguous.
From the tool's definition Tool name 'conversations_rename' and description 'Rename a conversation' indicate modification of channel/conversation metadata. This creates a reversible change to Slack workspace structure.
Attacks that exploit this kind of access

conversations_rename stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Slack, apply this rule, and every conversations_rename call is checked against it from then on.
