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 prompt embeds apparent API-secret values in the Environment Variables section (e.g., ANTHROPIC_API_KEY=sk-ant-..., SUPABASE_KEY=eyJ...), which would require or encourage the model to handle and potentially reproduce secrets verbatim (e.g., when generating .env files or deployment instructions), creating an exfiltration risk.
