2 findings: 1 high severity, 1 medium severity. You should review these findings carefully before considering using this skill.

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 skill instructs the agent to read and edit user settings files (using read_file/edit_file) and to produce JSONC config examples, which can require embedding real API keys or passwords verbatim into outputs rather than using secure references like env vars, creating an exfiltration risk.

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 instructs the agent to read and edit configuration files (using read_file/edit_file) and lists system-level config paths (e.g. /etc/qwen-code/settings.json), which enables modifying system files that may require sudo and thus can change the machine state.
