3 findings: 1 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.

Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This content configures automatic export of traces/logs/metrics (including VCS and environment data) to an external ingest endpoint and explicitly advises inlining authorization keys, creating a strong potential for unauthorized data exfiltration and credential exposure.

Report incorrect finding
High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

The prompt instructs replacing the placeholder ingest key (MAPLE_TEST) and inlining it into JVM args and Java source (headers/variables), which requires the model to emit secret values verbatim in commands or code.

Medium

W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The skill explicitly tells the user to keep JVM args inline in deployment artifacts including "systemd unit", which directs modifying systemctl/service files (a privileged, system state–changing action).

Low

Low-risk findings.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill fetches and then executes a remote Java agent jar at runtime (curl to https://github.com/open-telemetry/opentelemetry-java-instrumentation/releases/latest/download/opentelemetry-javaagent.jar and used via -javaagent), which downloads and runs remote code in the JVM.
