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 examples and MCP calls include explicit password and token fields (e.g., password, reset_token, new_password) that the agent would need to insert verbatim into generated tool invocations/requests, creating an exfiltration risk.
