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 skill explicitly directs the agent to record and preserve "final tool args" and "exposed secret surface" and to reproduce exploit chains that show secret exposure, which requires including secret values verbatim and is therefore high risk.
