## What it does

The most-starred community video project of 2026 (72K stars; once #1 repository of the day on GitHub Trending). You clone the repo and run Claude Code, Codex, Cursor, Copilot or Windsurf inside it; agent guides route a request, or a video you paste as a reference, into one of 12 production pipelines with 100+ tools and about 140 SKILL.md knowledge packs covering generation providers, Remotion and HyperFrames composition, three.js, TTS and speech-to-text, character animation QA and more. Provider adapters span fal.ai, Atlas Cloud, Kling, ElevenLabs, Fish Audio, BFL, xAI and others, each with your own keys. In the Agent Skills Hub end-to-end test it made a 15-second promo with a look of its own in 8.6 minutes.
