High

W007: Insecure credential handling detected in skill instructions.

What this means

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.

Why it was flagged

The prompt repeatedly instructs the model to "Quote the user's current instruction verbatim", which forces the LLM to reproduce any secrets contained in the user's input and thus creates a direct exfiltration risk.
