WHAT IT DOES

What tamper_add_file_deny does on Aapanel

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

RISK

Why tamper_add_file_deny is rated Medium

This tool modifies configuration state by adding tamper protection to files/directories. While it prevents modifications rather than making them, the act of 'adding' protection is itself a reversible configuration change (protection can be removed). This qualifies as Write rather than Execute because it configures access control rather than executing arbitrary commands.

From the tool's definition Tool name 'tamper_add_file_deny' and description 'Add file tamper protection (lock a file/directory from modification)' indicates it modifies system protection settings for files/directories.

tamper_add_file_deny Rate-limited

tamper_add_file_deny stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
