MMI workflow skills and org gates delivery.
AI Security Review
scanned 5d ago · by lpm-firewall-aiSource inspection found no lifecycle hook or concrete attack behavior. The flagged agent paths are used for path classification, while CLI telemetry sends a limited product-usage payload to the package's Hub endpoint.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running a CLI command triggers the pre-action hook.
Impact
The inspected telemetry payload contains no credentials or private prompt, response, or tool content.
Mechanism
The hook sends the command name, package version, CI status, and operating system to the default Hub telemetry endpoint.
AI rationale
Source inspection found no lifecycle hook or concrete attack behavior. The flagged agent paths are used for path classification, while CLI telemetry sends a limited product-usage payload to the package's Hub endpoint.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json contains no lifecycle scripts; its package metadata identifies the MMI Hub project.
- The CLI sends command name, version, CI status, and operating system to its default Hub telemetry endpoint; it does not include credentials in this payload.
- The telemetry is triggered by the CLI command pre-action hook.
- The agent-directory code classifies paths for filtering; it does not modify agent configuration.
