SKILL.md

Automatically analyze Bilibili videos, extract frames, and generate structured documentation or tutorials using AI.

Downloads videos via Bilibili API, extracts frames using FFmpeg at configurable rates (1 fps for short videos, 0.5 fps for medium, 0.2 fps for long), and deduplicates similar adjacent frames

Batch-analyzes extracted frames in parallel using the Task tool, with dynamic batching strategy based on total frame count (1–5 batches)

Reorganizes analysis results into polished markdown documents (tutorials for how-to content, structured guides for knowledge videos) with embedded screenshots and source-code attribution

Requires .NET 10 SDK and FFmpeg; supports custom output directories, frame-rate tuning, and similarity thresholds for deduplication
