What keyid_set_auto_reply does on KeyID Agent Kit

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

WHY IT NEEDS A POLICY

Why keyid_set_auto_reply needs a policy

This tool creates or modifies email settings—specifically the auto-reply/vacation responder configuration. While seemingly low-risk, it can be misused to alter how an account communicates with senders, potentially for social engineering or impersonation purposes. The reversible nature and lack of destructive/financial impact place it in Write rather than Execute.

From the tool's definition Tool modifies email account configuration ('Configure auto-reply'), which is reversible (enabled=false to disable). No data deletion or external financial operations involved.
