WHAT IT DOES

What container_file_delete does on Cloudflare

AI agents call container_file_delete to permanently remove resources in Cloudflare, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why container_file_delete is rated Critical

Deleting a file is an irreversible operation that cannot be undone. This falls squarely into the Destructive category. Severity is high because an AI agent could accidentally or maliciously remove critical files, though the impact is limited to the container's working directory rather than production systems. Confidence is high due to explicit use of 'delete' in both name and description.

From the tool's definition Tool name is 'container_file_delete' and description states 'Delete a file in the working directory.' The verb 'delete' is explicitly destructive.

RECOMMENDED RULE

The rule that runs container_file_delete safely

container_file_delete Hidden

container_file_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
