AI Security Review
scanned 3d ago · by lpm-firewall-aiThe seal marker is an explicit instruction to hide a state divergence from the user, and the refine-plan workflow propagates it into generated artifacts. This is reviewer manipulation in the package’s AI-agent guidance, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
An agent follows the refine-plan skill or uses the frontmatter helper to create an artifact that it later reads.
Impact
An agent may conceal stale or mismatched plan details from the user or a reviewer.
Mechanism
The skill inserts a seal marker that tells the agent not to report divergence from the current state.
Attack narrative
The package’s plan-writing guidance inserts a marker instructing AI agents not to report divergence from the current state. That can suppress findings about stale or mismatched plans when an agent later reads the generated artifact.
AI rationale
The seal marker is an explicit instruction to hide a state divergence from the user, and the refine-plan workflow propagates it into generated artifacts. This is reviewer manipulation in the package’s AI-agent guidance, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 90.0% confidence as Malware with low false-positive risk.
Evidence for block
- The seal marker tells AI agents not to report when a sealed file diverges from the current state.
- The refine-plan guidance adds that marker to revised plans, and the frontmatter helper emits it into generated artifacts.
Evidence against
- The package describes itself as a CLI for installing reusable AI-agent guidance, and has no install lifecycle scripts.
- The flagged relay helper appends session events to local files; the reviewed relay path shows no network transmission.
