What initshutdown_delete does on Nasbridge
AI agents call initshutdown_delete to permanently remove resources in Nasbridge, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why initshutdown_delete is rated Critical
The tool permanently removes an init/shutdown script, which cannot be undone without recreating it. This is a destructive operation that could disrupt system startup/shutdown sequences if the wrong script is deleted. While not as critical as deleting all storage, it represents an irreversible data loss action warranting the Destructive category and high severity due to potential system instability impacts.
From the tool's definition Tool name contains 'delete' and description states 'Delete an init/shutdown script' — this irreversibly removes a script that executes during system initialization or shutdown.
