Delete a comment.
AI agents call delete_comment to permanently remove resources in Todos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a comment permanently removes data that cannot be recovered without external backups. This is a destructive operation. While the blast radius is somewhat limited (comments are typically secondary to tasks), the irreversible nature of deletion and potential for loss of important context or discussion history warrants 'high' severity in a task management context.
From the tool's definition Tool name is 'delete_comment' with description 'Delete a comment.' The verb 'delete' indicates irreversible removal of data.

Yes. Add a rate_limit block to the delete_comment rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
