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 includes a deployment command that requires passing a deploy token via the --token flag on the command line, which would force the agent to insert a secret verbatim into generated commands or outputs.
