GE Demo Video Generator Skill (v2.2.0)

Automates the end-to-end production and delivery of professional 90–120s executive highlight reel demo videos showcasing autonomous AI agents deployed on Gemini Enterprise.

🌟 Core Architectural Invariants

1. Authentic Screen Recording Exclusively (Zero-Mock Invariant):

   • The skill strictly forbids synthetic mock video generation, mock SVG frames, and fallback presentation slides.
   • Video capture is executed directly against the live Gemini Enterprise chat session (https://vertexaisearch.cloud.google.com/home/cid/.../r/agent/.../session/-) of the deployed agent via Chromium DevTools Protocol (CDP, port 9222).
   • The chat interface DOM elements (div.ProseMirror, div[contenteditable="true"], or shadow DOM chat inputs) must be probed and verified before recording starts.

2. Universal Multi-Language Font Verification & Provisioning:

   • Before recording or rendering, the skill verifies that the necessary typography fonts for the target locale (e.g., Japanese CJK for ja-JP, Simplified/Traditional Chinese for zh, Korean Hangul for ko, Arabic for ar, Thai for th, Devanagari for hi, etc.) are installed on the host environment.
   • If missing, the automated font engine (ensure_fonts.py) installs them via system packages (apt-get) or downloads Google Noto font assets directly into ~/.local/share/fonts/ followed by fc-cache refresh, eliminating tofu (□) characters.
   • Remotion composition incorporates Google Web Fonts as a secondary defensive layer.
