Security checks for vulnerabilities and agentic risk

Overview

This skill is a small manager for IM and OpenClaw-related skills, but it asks agents to install or update multiple mutable skill packages without verifiable source or version details.

Install only if you trust the package source for the listed mmxagent skills. Before approving any install or update, verify the publisher, exact version, registry/source, and ideally a signature or digest; treat updates as persistent changes to your agent's capabilities.

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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 86% confidence
Finding: The description says the skill may be consulted 'when the user does some operations' and to 'look through this skill content' for updates, but it does not define specific trigger phrases, scope boundaries, or exclusion conditions. This ambiguity could cause the skill to be invoked in many ordinary situations involving generic user actions.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 78% confidence
Finding: The natural-language instructions are written entirely in Chinese and do not indicate that users may choose another language or locale. This can violate language/locale policy when the skill is used in broader multilingual contexts without explicit opt-in or documented regional limitation.
Content: No source excerpt is available for this finding.
