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: 0.90). The skill explicitly says decryption keys may be "available or prompted for," which encourages the agent to request and handle secret keys directly (potentially echoing them into commands or outputs) rather than keeping them in protected env/config, so it risks secret exposure.
