YouTube‑Clipper Skill

This skill automates YouTube video clipping, subtitle generation, and bilingual translation using Claude. It leverages yt‑dlp and ffmpeg to download videos, performs semantic analysis of subtitles to extract meaningful segments, and produces platform‑specific short clips (e.g., TikTok, Xiaohongshu). It also batch‑translates subtitles to Chinese‑English bilingual format and can embed the subtitles into the video.

skill‑from‑masters

This tool creates new Skills by mining expert knowledge. It uses a three‑layer search architecture: (1) query a local expert database, (2) perform web search for additional viewpoints, and (3) deep‑source verification of primary materials. The system extracts best‑practice patterns, avoids common pitfalls, and synthesizes high‑quality Skill instructions. It also offers a skill‑from‑github mode that analyzes selected open‑source repositories to extract algorithms or design patterns and turn them into reusable Skills.

NotebookLM Skill

This Skill enables Claude Code to interact directly with Google NotebookLM. It runs a dedicated Python environment using Patchright (a Playwright‑based library) to automate browser actions: logging in, maintaining session persistence, and managing notebooks. Users can query their personal knowledge base via natural language, and Claude retrieves and synthesizes answers from NotebookLM.

Markdown‑to‑X Publisher Skill

The Skill converts local Markdown articles into posts for X (formerly Twitter). It preserves rich formatting and inserts images accurately using a Block‑Index positioning technique, which calculates each image’s exact location in the article structure and injects it via browser automation. This solves X’s limited native Markdown support and manual image handling.
