1 high severity finding. You should review these findings carefully before considering using this skill.
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.
Insecure credential handling detected (high risk: 1.00). The skill's example and toolkit require the agent to emit RPC/command payloads containing env_vars (e.g., API_KEY: "key") and file contents, meaning any real API keys or passwords provided would be included verbatim in the agent's generated mcp calls/outputs and thus exposed.
