Why machine_onboarding_remove is rated Critical
The tool irreversibly deletes stored credentials and authentication tokens. While not deleting user data per se, removing vault tokens and clone credentials are destructive actions that cannot be easily undone and will break CI/CD pipelines and repository access. This has a high blast radius if invoked incorrectly on production machines.
From the tool's definition Tool performs 'Remove' operations on GitHub/GitLab onboarding, including removal of 'clone credentials' and 'CI/deploy vault tokens' from machines.
