gemini-video-understanding
Analyze videos using Google's Gemini API - describe content, answer questions, transcribe audio with visual descriptions, reference timestamps, clip videos, and process YouTube URLs. Supports 9 video formats, multiple models (Gemini 2.5/2.0), and context windows up to 2M tokens (6 hours of video).

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.90). The skill explicitly accepts and processes public YouTube URLs (see SKILL.md, EXAMPLES.md and scripts/analyze_video.py where --youtube-url is passed as a file_uri to the Gemini API), so the agent ingests untrusted, user-generated third‑party content that can directly influence model outputs and downstream actions.
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
Potentially malicious external URL detected (high risk: 0.80). The skill accepts and sends YouTube URLs (e.g. https://www.youtube.com/watch?v=VIDEO_ID) at runtime directly as a file_uri to the Gemini API, causing remote video content to be fetched and injected into the model's context (i.e., directly controlling the agent's inputs/outputs).
