AI Security Review
scanned 25d ago · by lpm-firewall-aiThe Antigravity adapter creates a persistent integration artifact, but only through the explicit installer and without activating it. This is a guarded first-party agent extension setup risk, so warn rather than block.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the package’s install command on a machine where Antigravity is among the selected editors.
Impact
If the user later activates it, the watcher can run the configured sync from a local development checkout. The code inspected does not establish covert execution or data theft.
Mechanism
The Antigravity adapter writes a sync script and a LaunchAgents plist but does not load the agent. Its warning says activation requires a separate manual load step.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes an explicit install command and has no npm lifecycle hook that automatically runs it.
- The editor integration locations are scoped to editor configuration, skill directories, uninstall cleanup, and transcript discovery.
- When the install command targets Antigravity, its adapter writes a sync script and a LaunchAgents plist under the user’s home directory.
- The adapter does not load the launch agent; activation requires a separate manual step, and the sync depends on a local development checkout.
Evidence against
- No install-time trigger, credential theft, or unrelated agent configuration write was established.
- The Antigravity watcher is not activated by the adapter itself.
