E004: Prompt injection detected in skill instructions.
What this means
Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.
Why it was flagged
The prompt embeds "system-reminder" directives that try to override normal testing procedures (e.g., "ignore any existing tests", "Do NOT use mock mode") which are hidden/authoritative-style instructions that change agent behavior outside the stated testing purpose and conflict with other guidance — this is a prompt-injection style override.
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 explicitly tells the agent to "ask me for credentials" and to test the real app (no mock mode), which requires the LLM to receive and likely embed verbatim secrets (e.g., in Playwright scripts or requests), creating an exfiltration risk.
