MMI workflow skills and org gates delivery.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package has no install lifecycle script, and the flagged agent-config code only filters git cleanliness results. The inspected network behavior is limited to command metadata telemetry and an explicitly enabled GitHub app flow, so the scanner's malicious label is not supported by source evidence.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Telemetry runs before a CLI command; app identity is activated only when the environment requests app mode for an eligible command.
Impact
The inspected behavior does not establish credential theft, unconsented agent configuration changes, or another concrete attack.
Mechanism
Telemetry posts the command name, version, CI status, and operating system to the MMI Hub endpoint. The app flow requests a GitHub installation token from api.github.com.
AI rationale
The package has no install lifecycle script, and the flagged agent-config code only filters git cleanliness results. The inspected network behavior is limited to command metadata telemetry and an explicitly enabled GitHub app flow, so the scanner's malicious label is not supported by source evidence.

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 contains package metadata and shipped paths but no lifecycle script.
- The flagged agent-config path match is used only to classify untracked paths in a git cleanliness check; it does not write agent configuration.
- CLI telemetry sends the command name, package version, CI status, and operating system to the MMI Hub endpoint, and can be disabled with MMI_TELEMETRY=off.
- Telemetry is triggered by a CLI command pre-action, not by package installation.
- The optional GitHub app identity flow defaults to the personal identity unless MMI requests app mode, and its token request goes to api.github.com.

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