Security
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 prompt embeds plaintext credentials (e.g., a DATABASE_URL with username:password and POSTGRES_PASSWORD=postgres and a sample API key-like string), which are explicit secret values that an LLM could reproduce verbatim — a high exfiltration risk.
