AI Security Review
scanned 13d ago · by lpm-firewall-aiThe manifest has no npm install lifecycle hook, and the flagged agent configuration and persistence behavior is reached through explicit setup. The Antigravity watcher requires separate manual activation, so the inspected source does not establish an attack surface.
Static reason
No blocking static signals were detected.
Trigger
A user invokes the setup or install command; Antigravity watcher activation requires a separate manual command.
Impact
These actions configure the product's editor integration; the inspected source does not establish unconsented install-time mutation or another concrete attack.
Mechanism
Setup writes editor MCP configuration and capture hooks. The Antigravity adapter writes a launch agent definition and directs the user to activate it manually.
AI rationale
The manifest has no npm install lifecycle hook, and the flagged agent configuration and persistence behavior is reached through explicit setup. The Antigravity watcher requires separate manual activation, so the inspected source does not establish an attack surface.
Decision evidence
public snapshotAI called this Clean at 89.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json lists a CLI entry point and release scripts, with no npm install lifecycle hook.
- The setup and editor writes are reached through the explicit setup command; the inspected adapters write MCP configuration and a capture hook.
- Antigravity setup writes a watcher definition but instructs the user to activate it manually; its script depends on a local checkout.
- The inspected dependency manifests contain no install scripts, and the inspected Zod entry points re-export the library.
- Uninstall filters for Cortex or Agnoclast namespaced launch agents and removes those artifacts.
Evidence against
- The package can write AI editor configuration and a launch agent during explicit setup; these are persistent integration capabilities, but the inspected source does not show an unconsented install-time trigger.
