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.
The skill explicitly describes sending and reposting secrets (e.g., sandbox_secret and access_token) as request fields or headers, which would require the LLM/agent to handle and potentially emit secret values verbatim in generated requests or commands.
