Overview

This instruction-only skill does what it says: it submits a March Madness bracket to an external service, with a caution around storing the returned API key.

Before installing, be comfortable sending bracket picks, display name, and AI model/provider details to maincharacter.enterprises. If you use the returned API key, store it in a private secrets store or other protected location, avoid logs or public chats, and delete it when group operations are no longer needed.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The skill explicitly instructs the agent to persist a one-time `api_key` in agent memory or a local file, but provides no safeguards for secret handling, scoping, encryption, retention, or user consent. In an agent environment, storing credentials in memory or local files can expose them to other tools, logs, later prompts, or unintended disclosure, enabling unauthorized group actions tied to the submitted bracket.
