AI Security Review
scanned 25d ago · by lpm-firewall-aiThe package has no install lifecycle hook or confirmed malicious behavior. Its explicit setup can create an Antigravity agent watcher that requires separate activation, so the package-owned agent integration merits a warning.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the CLI setup command and then loads the generated launch agent.
Impact
This creates an optional, package-owned agent integration that may run automatically after activation; the inspected source does not establish credential theft or unrelated configuration changes.
Mechanism
The watcher monitors Antigravity's local state and invokes the package's `with-token` command to run a sync from a local development checkout.
AI rationale
The package has no install lifecycle hook or confirmed malicious behavior. Its explicit setup can create an Antigravity agent watcher that requires separate activation, so the package-owned agent integration merits a warning.
Evidence
lib/editors/antigravity.mjslib/setup.mjsbin/cortex-mcp.mjs
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json has no install lifecycle hook; it exposes the package through a CLI entry point.
- The CLI calls setup only when the user invokes the setup command.
- Antigravity setup writes a sync script and launch agent; the generated job invokes this package when run.
- The watcher requires a separate `launchctl load` command to activate, and the script uses the package's own `with-token` command.
- The package also contains integrations for Codex and Cursor, skill installation into Claude and Codex directories, uninstall support, and transcript lookup.
Evidence against
- The Antigravity watcher is not activated by setup itself; activation requires a separate command.
- The Antigravity script passes the token through the package's own token resolver rather than embedding it in the script.
