render-model-comparison-grid
Render a 'model comparison grid' video from a config — a fal-style "same prompt, N contenders" showcase — a dark real-DOM stage where per beat a monospace prompt fades in centered, docks to a small top strip, then a labeled 2-4 panel grid (static images OR muted video clips, mixable per cell) staggers in and holds for comparison, plus a minimal end card — frame-stepped via Playwright (video cells are frame-seeked deterministically) and encoded with FFmpeg. Deterministic assembly, FREE (cell media comes from create-image-fal / create-video-fal, music from create-music-elevenlabs), text stays pixel-crisp. Use for the model-comparison-grid format.

E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The code unsafely injects untrusted config strings directly into HTML/JS (innerHTML and a <script> block) which enables arbitrary JavaScript execution when the generated file is opened by Playwright — this can be abused for remote code execution and data exfiltration (fetching remote URLs or reading/encoding local media) even though no explicit malicious payloads are present.
Low
Low-risk findings.
1 low severity finding. 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
Outsider-authored free text can enter via the user-provided `config.json` (fields `beats[].prompt`, `beats[].tag`, `columns[].label`, `endcard.headline/subline`) which `build_composition.py` embeds into first-party generated HTML/DOM and the renderer then loads and executes in Chromium at runtime.
