RISK

Why restore_file_version is rated Medium

This tool modifies file data by restoring an older version as the current version. While it doesn't delete the old version or destroy data irreversibly, it does overwrite the current file state, making it a Write operation.

From the tool's definition Tool description states it 'Restore a previous version of a file (creates a new current version from the old one)' — this creates/modifies file content by reverting to a prior state.

restore_file_version Rate-limited

restore_file_version 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.
