video-agent-skills

A CLI tool that critiques motion/design videos using Gemini, plus a Claude Code skill bundle for one-command installs.

What it does

• Uploads a video to Gemini and returns blunt, production-focused feedback
• Surfaces strengths, issues, and concrete improvements
• Works as a CLI and as a Claude Code Skill

Install (CLI)

./scripts/install.sh

Then run:

video-agent-skills feedback -video /path/to/video.mp4

Reverse engineer the likely prompt used to create a finished video:

Example .env:

GEMINI_API_KEY=your_key_here
