AI Security Review
scanned 25d ago · by lpm-firewall-aiClassify as suspicious because the user-configured Antigravity integration can run later package releases when its event-triggered sync runs. The excerpts inspected do not establish malicious behavior or a publish-blocking attack.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user configures the Antigravity integration, then the watched Antigravity state changes.
Impact
A later package release may run during a subsequent sync, creating a guarded agent extension lifecycle risk; the inspected source does not establish malicious behavior.
Mechanism
The generated launch agent starts a script that invokes npx with the package’s stable release tag and runs its token wrapper before the sync command.
AI rationale
Classify as suspicious because the user-configured Antigravity integration can run later package releases when its event-triggered sync runs. The excerpts inspected do not establish malicious behavior or a publish-blocking attack.
Evidence
lib/editors/antigravity.mjslib/setup.mjs
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes a command-line entrypoint and has no install lifecycle hook in its manifest.
- The Antigravity adapter generates a launch agent that watches the Antigravity state directory and starts a sync after changes.
- That sync invokes the package’s moving stable release through npx when triggered.
- Setup explicitly selects a moving release tag, so a configured machine can receive later releases on a subsequent sync.
- The Codex and Cursor adapters configure Cortex entries; the setup path requires a token before wiring these integrations.
- The uninstall command is explicitly invoked and offers a dry-run mode before changing configuration.
Evidence against
- The Antigravity adapter sets RunAtLoad to false; its generated agent is event-triggered.
- The sync is scoped to the package’s Antigravity integration and uses a local checkout path; the source describes that path as a portability limitation.
- No concrete credential theft, unrelated control-surface mutation, or other active attack was established from the inspected excerpts.
