AI Security Review
scanned 20d ago · by lpm-firewall-aiThe package has no npm lifecycle hook, and the persistence finding is an explicit setup artifact that is not activated automatically. However, setup enables later automatic installation of organization-published agent instructions without per-skill approval, leaving a bounded agent-extension lifecycle risk.
Static reason
No blocking static signals were detected.
Trigger
The user runs login, setup, or install; later Claude sessions invoke the configured skills-repair hook.
Impact
Updated skill instructions may change how the agent behaves in those sessions.
Mechanism
The package fetches skills using the configured account token and writes their content into detected agent skill directories; the SessionStart hook repeats the sync.
AI rationale
The package has no npm lifecycle hook, and the persistence finding is an explicit setup artifact that is not activated automatically. However, setup enables later automatic installation of organization-published agent instructions without per-skill approval, leaving a bounded agent-extension lifecycle risk.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json declares no install lifecycle hook; the CLI dispatches setup, install, and uninstall as explicit commands.
- Antigravity wiring runs only through the install command; it writes a launch agent with RunAtLoad disabled and does not activate it.
- The reviewed editor adapters and helpers target their named editor configuration, managed skills, or transcript files.
- Setup and session repair fetch authenticated org-published skills from the package’s service and install them into detected Claude and Codex skill directories.
- Claude setup adds a SessionStart skills-repair command, which can refresh org-published skills in later sessions without a per-skill approval step.
Evidence against
- The Antigravity artifact is inert until the user manually loads it, and its generated sync script depends on a local development checkout.
