1 high severity finding. You should review these findings carefully before considering using this skill.
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 instructs the agent to embed user-provided text verbatim into command-line arguments (e.g., --question, --answer, --user-answer, --questions JSON), which would force the LLM to include any secret values the user supplies directly in its generated commands and outputs, creating an exfiltration risk.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The workflow for “Quiz from a YouTube video” fetches a runtime YouTube transcript (outsider-authored free text from public web content) in `scripts/youtube_quiz.py fetch`, which returns `{"transcript": "..."}` and is then fed into the agent LLM as context for generating quiz questions.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill fetches a YouTube video's transcript at runtime (user provides URLs like https://www.youtube.com/watch?v=dQw4w9WgXcQ) and injects that remote transcript into the LLM context to generate quiz questions, so the external content directly controls prompts.
