AI Security Review
scanned 24d ago · by lpm-firewall-aiInspected source supports user-invoked setup and maintenance of the package’s own agent integrations; the manifest has no install lifecycle hook. The flagged persistence is part of the Antigravity adapter, and no malicious attack behavior was established.
Static reason
No blocking static signals were detected.
Trigger
A user invokes the CLI setup or install command.
Impact
No confirmed malicious effect or unconsented install-time mutation was established.
Mechanism
Setup writes package-owned MCP, hook, skill, and editor configuration; the inspected manifest contains no npm install lifecycle hook.
AI rationale
Inspected source supports user-invoked setup and maintenance of the package’s own agent integrations; the manifest has no install lifecycle hook. The flagged persistence is part of the Antigravity adapter, and no malicious attack behavior was established.

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 defines a CLI entrypoint and no install lifecycle hooks.
- The Codex and Cursor adapters describe their configuration wiring as explicit editor setup; no install-time trigger is shown.
- The package’s skill installer targets Claude Code and Codex skill directories.
- The uninstall module removes the package’s own managed configuration and hooks.
- The working-files excerpt reads Claude session files; it does not establish credential harvesting or exfiltration.
- Antigravity’s adapter describes sync as a launch agent; this is setup behavior, not an npm install hook.
- The CLI entrypoint describes explicit setup and ordinary MCP server operation.
