MMI workflow skills and org gates delivery.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package has no install lifecycle hook, and the flagged agent path is used only by a Git cleanliness check. The observed telemetry and credential exchange are tied to user-invoked CLI and MMI Hub workflows, with no unrelated credential recipient or concrete attack behavior identified.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user invokes a CLI command; Hub authentication occurs when a command needs a Hub session.
Impact
No harmful impact was established; the inspected transfers support the plugin's Hub workflow.
Mechanism
The CLI sends command and basic environment metadata to the MMI Hub, and exchanges a GitHub token with the configured Hub auth endpoint.
AI rationale
The package has no install lifecycle hook, and the flagged agent path is used only by a Git cleanliness check. The observed telemetry and credential exchange are tied to user-invoked CLI and MMI Hub workflows, with no unrelated credential recipient or concrete attack behavior identified.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json identifies this as an MMI workflow plugin and defines no lifecycle scripts.
- The flagged .codex path is part of a Git cleanliness check; only untracked agent configuration paths are exempted from blocking that check.
- After a user invokes a CLI command, the CLI sends the command name, version, CI status, and operating system to the MMI Hub; telemetry can be disabled with MMI_TELEMETRY=off.
- GitHub credentials are sent to the configured Hub's auth-session endpoint to obtain a Hub session; the default Hub endpoint is the package's MMI service.
Evidence against
- Usage telemetry is sent automatically for CLI commands unless disabled.
- The Hub session exchange sends a GitHub token to the configured Hub endpoint.

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