AI Security Review
scanned 12d ago · by lpm-firewall-aiSource inspection found no install-time execution or concrete attack behavior. The flagged configuration changes are associated with explicit setup or channel commands, and Antigravity wiring does not load its generated launch agent.
Static reason
No blocking static signals were detected.
Trigger
A user invokes setup, install, or channel configuration.
Impact
No confirmed attack surface was established.
Mechanism
The commands merge package configuration into supported agent settings; the package manifest has no install lifecycle hook.
AI rationale
Source inspection found no install-time execution or concrete attack behavior. The flagged configuration changes are associated with explicit setup or channel commands, and Antigravity wiring does not load its generated launch agent.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines no install lifecycle hook; its scripts are release, promote, and rollback.
- The flagged agent configuration writes are reached through setup or channel commands and modify MCP or hook configuration.
- Codex setup requires a supplied token; Cursor preserves existing MCP entries and skips malformed configuration.
- Antigravity wiring writes files but does not load the launch agent.
- The inspected dependency manifests and entrypoints show ordinary SDK and validation-library exports.
