AI Security Review
scanned 12d ago · by lpm-firewall-aiThe flagged configuration and persistence behavior is tied to explicit CLI setup or removal. The Antigravity watcher is not activated by the package, and no concrete attack behavior remains after source inspection.
Static reason
No blocking static signals were detected.
Trigger
A user runs setup, install, or uninstall; no npm install lifecycle hook is defined.
Impact
No unconsented credential transfer, destructive action, or automatically activated persistence was established.
Mechanism
The Antigravity adapter writes a watcher script and plist, but the plist is not set to run at load and the adapter tells the user to load it separately.
AI rationale
The flagged configuration and persistence behavior is tied to explicit CLI setup or removal. The Antigravity watcher is not activated by the package, and no concrete attack behavior remains after source inspection.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI and defines no npm install lifecycle hook.
- Setup, install, and uninstall run as CLI commands; uninstall removes the package’s named MCP entries.
- The Codex and Cursor adapters gate configuration writes on a token and write to their respective MCP configuration files.
- The Antigravity adapter writes a watcher script and plist, but its source requires a separate load command and sets RunAtLoad to false.
- Inspected runtime code sends authenticated graph data to the Agnoclast service and invokes Claude through the local CLI for review tasks.
- The declared dependencies are the MCP SDK and Zod; the inspected Zod entrypoints re-export library modules.
