Delete a stream from a campaign. This removes the stream permanently.
AI agents call keitaro_delete_stream to permanently remove resources in Keitaro MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes data (a stream) with no undo capability. Permanent deletion is the defining characteristic of the Destructive category. While the blast radius is limited to a single stream rather than an entire campaign, the irreversibility and potential loss of tracking configuration justifies 'high' severity.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a stream from a campaign. This removes the stream permanently.' The word 'permanently' indicates irreversible data loss.
