AI Security Review
scanned 16d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the reviewed agent configuration and persistence behavior is tied to explicit CLI setup or installation. The flagged Antigravity launch agent is dormant until manually loaded, so the inspected source does not establish malicious behavior.
Static reason
No blocking static signals were detected.
Trigger
A user invokes setup or install; Antigravity activation additionally requires the user to load its launch agent.
Impact
No confirmed attack surface or unconsented persistence was established.
Mechanism
The package writes its editor configuration, managed skills, and Antigravity sync artifacts. The Antigravity plist is not configured to run at load.
AI rationale
The manifest has no install lifecycle hook, and the reviewed agent configuration and persistence behavior is tied to explicit CLI setup or installation. The flagged Antigravity launch agent is dormant until manually loaded, so the inspected source does not establish malicious behavior.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines a CLI entrypoint and has no npm install lifecycle hook.
- The CLI routes setup, install, and uninstall through explicit subcommands.
- Cross-editor install invokes selected or detected adapters; the Antigravity adapter writes its sync script and launchd plist.
- The Antigravity plist does not run at load, and the adapter tells users to activate it manually.
- Setup installs managed skills into detected Claude and Codex directories; uninstall removes managed wiring and launch agents when invoked.
