What problem does it solve? Video tutorials hide their most important information on screen — the code being typed, the commands run, the versions in title bars — which transcripts and captions completely miss. This Skill watches the video's visual track through Gemini and turns it into a structured, replicable guide you can actually learn from and build against. ## Core Features & Use Cases - Visual-track extraction: Sends a YouTube URL or local video file to Gemini and recovers exact code, commands, versions, and UI actions shown on screen, with timestamps and illegible sections explicitly flagged. - Critical review and replication: Reads the extraction skeptically, verifies APIs and versions against real documentation, then actually rebuilds the project using locally installed versions and reports what worked and what failed. - Improvement over the source: Uses the extraction's Weaknesses section to fix outdated, insecure, or fragile tutorial patterns, clearly documenting every departure from the video. - Use Case: You find a 40-minute YouTube screencast building an auth middleware. Run the Skill to get the exact code and steps from the screen, learn why the approach works, reproduce it with your installed dependency versions, and receive a hardened version with the tutorial's shortcuts fixed. ## Quick Start Analyze this YouTube tutorial at the given URL, explain the technique it teaches, and rebuild the project it demonstrates using my current environment.
