AI Security Review
scanned 13d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the flagged configuration and persistence behaviors are tied to explicit setup or uninstall operations. The Antigravity adapter writes artifacts without activating its watcher; the inspected source supports a clean verdict.
Static reason
No blocking static signals were detected.
Trigger
Explicit setup or uninstall commands; Antigravity watcher activation requires a separate launch-agent load action.
Impact
The inspected behavior configures or removes the package’s integrations; no unconsented install-time mutation or confirmed harmful effect was identified.
Mechanism
Setup writes package MCP configuration and generated Antigravity artifacts; uninstall removes the package’s own wiring and related artifacts.
AI rationale
The manifest has no install lifecycle hook, and the flagged configuration and persistence behaviors are tied to explicit setup or uninstall operations. The Antigravity adapter writes artifacts without activating its watcher; the inspected source supports a clean verdict.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package manifest defines no install lifecycle hook; its scripts are release, promotion, and rollback commands.
- The Codex and Cursor adapters and setup path write MCP configuration as part of setup operations.
- The inspected dependency manifests show no install lifecycle hooks; the inspected Zod entrypoints export the library.
- The command-line entrypoint dispatches setup and uninstall as explicit commands.
- The flagged Antigravity adapter writes a script and launch-agent file but does not activate the launch agent itself.
- Uninstall behavior is invoked through an uninstall/remove command and targets the package’s own configuration and artifacts.
