YukkuriMovieMaker4（YMM4）をMCPで操作するスキル。 ゆっくり実況動画の制作補助に使う。 以下の場面で必ず使うこと： - 「ゆっくり実況を作って」「セリフを追加して」「タイムラインを編集して」 - 「映像を確認して」「音声を確認して」「BGMを調べて」 - 「セリフと映像を合わせて」「重複をチェックして」 - 「スケルトンキング」「マインクラフト」等の動画内容への言及 - YMM4・ゆっくりムービーメーカー・ゆっくり動画に関する操作全般.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add scpgamerscp/ymm4mcp/ymm4-mcp@sha256:25bea1bb1fbb33b6The line at the top of this page pins the label git:20260925.4904b61, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
