Delete a scheduled RCS message
AI agents call delete_rcs to permanently remove resources in Seven — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a scheduled RCS message, which cannot be undone. Deletion of scheduled communications is an irreversible operation that destroys data. While not critical in scope (confined to a single message rather than mass data), the destructive nature of permanent deletion elevates it above Write (which is reversible).
From the tool's definition Tool name is 'delete_rcs' and description states 'Delete a scheduled RCS message' — the verb 'Delete' combined with the action of removing a scheduled message indicates irreversible data destruction.

Yes. Add a rate_limit block to the delete_rcs 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.
