AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a real, user-invoked agent extension lifecycle that captures and uploads session data, so it warrants a warning. Static inspection found no concrete malicious install chain or automatic lifecycle execution.
Static reason
No blocking static signals were detected.
Trigger
A user runs the package setup or install command, then an installed editor emits a configured hook event.
Impact
Session content may be transmitted to the configured organization service; future package releases can run through the npx hook commands.
Mechanism
AI-editor hook installation and authenticated session-data ingestion
AI rationale
The package has a real, user-invoked agent extension lifecycle that captures and uploads session data, so it warrants a warning. Static inspection found no concrete malicious install chain or automatic lifecycle execution.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The explicit setup command writes a Codex Stop hook that runs the package capture command.
- The capture hook reads session transcripts, can include the transcript in its ingest body, and posts that body to the service.
- The Antigravity adapter writes a launchd plist and executable sync script when selected.
Evidence against
- package.json has no preinstall, install, postinstall, or self-dependency.
- Configuration changes are reached through explicit CLI setup or install commands, not npm lifecycle execution.
- The launchd adapter does not load the generated agent itself and reports activation as a separate user action.
- No obfuscation, secret harvesting beyond the configured service token, or unrelated network endpoint was found.
