AI Security Review
scanned 13d ago · by lpm-firewall-aiThe package has no npm install lifecycle hook, and the flagged configuration changes are tied to explicit CLI actions. The Antigravity adapter does not activate its launch agent, and no concrete attack behavior was identified in the inspected source.
Static reason
No blocking static signals were detected.
Trigger
A user invokes the setup, install, or uninstall CLI command.
Impact
No confirmed malicious effect was found.
Mechanism
Setup writes the package's editor configuration; Antigravity setup writes launch-agent files without activating them. Uninstall removes managed entries and supports a dry run.
AI rationale
The package has no npm install lifecycle hook, and the flagged configuration changes are tied to explicit CLI actions. The Antigravity adapter does not activate its launch agent, and no concrete attack behavior was identified in the inspected source.
Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json lists no npm install lifecycle hook; its scripts are release, promote, and rollback. The CLI routes setup and uninstall through explicit commands.
- The Codex and Cursor adapters write the package's own MCP configuration entries, preserving other entries. Setup requires a supplied token.
- Antigravity setup writes its script and launch agent file but does not load the agent; the source identifies a manual activation step.
- Uninstall is an explicit CLI command, supports a dry run, and backs up configuration before editing it.
- Inspected runtime helpers describe local transcript, graph, and review workflows; no attack behavior was identified in those paths.
- The inspected dependency manifests identify the declared SDK and Zod packages; Zod entrypoints re-export their library modules.
