AI Security Review
scanned 20d ago · by lpm-firewall-aiThe manifest has no npm install hook, and the flagged agent configuration and persistence behaviors are part of explicit setup or uninstall flows. The inspected capture path sends data to the package's configured Agnoclast service; no concrete attack behavior was found.
Static reason
No blocking static signals were detected.
Trigger
A user runs the install, setup, or uninstall command; no npm install lifecycle hook is defined.
Impact
No confirmed harmful effect.
Mechanism
The commands configure or remove this package's agent integration. Antigravity setup writes a launch agent file but leaves it unloaded.
AI rationale
The manifest has no npm install hook, and the flagged agent configuration and persistence behaviors are part of explicit setup or uninstall flows. The inspected capture path sends data to the package's configured Agnoclast service; no concrete attack behavior was found.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json has no install lifecycle hook; its scripts are release, promote and rollback.
- The CLI dispatches install and uninstall only for those explicit commands; uninstall removes Agnoclast wiring.
- Antigravity setup writes a watcher script and launch agent, but does not load it automatically; its plist has RunAtLoad disabled.
- Agent integration targets concern the package's MCP configuration and managed skills. The uninstall path removes its own managed entries.
- findTranscript looks for a caller-supplied session ID in the Claude projects directory.
- Capture posts to the Agnoclast ingest API; the configured canonical service is agnoclast.com.
