MMI workflow skills and org gates delivery.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe manifest has no lifecycle hooks, and the flagged agent-configuration excerpt only classifies paths. The observed CLI telemetry reports limited usage metadata to the configured package hub and does not establish an attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
CLI invocation triggers telemetry unless MMI_TELEMETRY is set to off.
Impact
The inspected behavior does not establish credential theft, unauthorized agent configuration changes, or another confirmed attack.
Mechanism
Telemetry sends the command, version, CI status, and operating system to the configured hub; the inspected agent-configuration excerpt only classifies paths.
AI rationale
The manifest has no lifecycle hooks, and the flagged agent-configuration excerpt only classifies paths. The observed CLI telemetry reports limited usage metadata to the configured package hub and does not establish an attack.
Decision evidence
public snapshotAI called this Clean at 84.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares no lifecycle scripts.
- The flagged agent-configuration code checks paths under agent configuration directories; the inspected excerpt shows path classification, not configuration mutation.
- CLI telemetry sends the command, version, CI status, and operating system to the package's configured hub.
Evidence against
- The CLI telemetry can be disabled with MMI_TELEMETRY=off.

Credential Exfiltration
Source appears to send environment or credential material to an external endpoint.
