1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The list includes a likely typosquatted/malformed NotebookLM URL (missing the expected .com) and a GitHub link to an unknown repository explicitly advertising "anti-detection" behavior for a browser automation tool—both are high-risk indicators for stealthy/malicious distribution or abuse.
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
In `scripts/ask_question.py`, the workflow takes outsider-authored `--question` free text and types it into NotebookLM via a browser session, then reads the resulting free-text answer from NotebookLM’s response selectors.
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's runtime browser automation directly navigates to NotebookLM (e.g., page.goto("https://notebooklm.google.com") and notebook URLs like "https://notebooklm.google.com/notebook/..."), captures the NotebookLM answers, and injects those answers (with follow-up prompts) into the agent flow—so external content from those URLs is fetched at runtime and directly controls agent prompts.
