Security checks for vulnerabilities and agentic risk

Overview

MoltGuard is a coherent security skill, but installing it would add a mutable third-party plugin that can route sensitive agent security data to an external Core service with limited disclosure.

Review this before installing in any environment with confidential prompts, customer data, credentials, or regulated information. Confirm the exact plugin version and publisher provenance, what Core endpoint is used, what data is transmitted, retention/deletion terms, credential handling, and how to disable or revoke access. Use enterprise enrollment only with a Core endpoint you administratively trust.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The skill documents automatic retrieval and storage of an API key in a local credentials directory without any warning about sensitivity, file permissions, rotation, or what account the key authorizes. This can lead users or downstream agents to expose, mishandle, or overtrust the stored credential, especially because the same section frames activation as automatic and zero-intervention.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The enterprise enrollment flow changes the backend endpoint to a private Core instance, but the documentation does not clearly warn that future security events, prompts, or metadata may be routed to a different service under different administrative control. This creates a real trust-boundary change and can cause unintended data disclosure if a user or agent enrolls without understanding where data will go.
Content: No source excerpt is available for this finding.

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The uninstall section provides a destructive command and only afterward notes that config, plugin files, and credentials are removed. For irreversible cleanup affecting user data and local configuration, the section should warn users before the command so they understand the impact in advance.
