AI Security Review
scanned 12d ago · by lpm-firewall-aiSource inspection found no npm install hook or concrete attack behavior. The flagged editor configuration changes are user-invoked product setup, and Antigravity persistence requires separate manual activation.
Static reason
No blocking static signals were detected.
Trigger
No automatic install trigger was found; the relevant behavior requires a user to invoke setup, install, or uninstall.
Impact
No malicious effect was identified from the inspected source.
Mechanism
No attack mechanism was established. The package writes its own MCP configuration and an inactive Antigravity watcher, while uninstall removes package-managed wiring.
AI rationale
Source inspection found no npm install hook or concrete attack behavior. The flagged editor configuration changes are user-invoked product setup, and Antigravity persistence requires separate manual activation.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes a CLI and lists no npm install lifecycle hook; the CLI dispatches setup and install only when those commands are invoked.
- setup validates a supplied token, and the editor adapters write the package's named MCP configuration entries.
- The Antigravity adapter writes a watcher script and plist, but does not activate them; it tells the user that activation requires a separate command.
- Uninstall is an explicit CLI command; its dry-run mode skips writes and its edits target managed package wiring.
- Network code uses the Agnoclast service base; the separate 1.1.1.1 request is a reachability probe.
- Inspected dependency manifests show no install lifecycle scripts; zod entrypoints re-export its library code.
