AI Security Review
scanned 25d ago · by lpm-firewall-aiSource inspection found an explicit setup capability that writes a platform watcher configuration, with activation left to the user. This merits a warning for agent extension lifecycle risk, but the inspected source does not establish an active attack.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user invokes the CLI setup flow on a machine where Antigravity is detected.
Impact
If the user activates the watcher, it can run the configured sync process when Antigravity data changes; the package source says this setup is not portable without that checkout.
Mechanism
Setup writes the watcher artifacts, but activation requires a separate launchctl command. The generated script depends on a local development checkout.
AI rationale
Source inspection found an explicit setup capability that writes a platform watcher configuration, with activation left to the user. This merits a warning for agent extension lifecycle risk, but the inspected source does not establish an active attack.
Evidence
lib/editors/antigravity.mjs~/.cortex/antigravity-sync.sh~/Library/LaunchAgents/com.cortex.antigravity-sync.plist
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json defines a CLI but no preinstall, install, or postinstall hook.
- The CLI reaches setup through an explicit setup command.
- Antigravity setup writes a shell script and LaunchAgents plist under the user's home directory.
- The plist watcher requires a separate launchctl command, and its script depends on a local development checkout.
- The inspected Codex, Cursor, skills, uninstall, and working-file code targets user agent configuration or session data.
Evidence against
- No automatic install-time trigger for the Antigravity setup was found.
- The inspected Antigravity setup does not load the watcher itself and reports that it requires manual activation.
