Edit, trim, cut, caption, retime, combine, or export video, audio, and image files through Cassette. Use this skill whenever the user asks to change, preview, or render media in the project, even if they never say "Cassette" or name a tool, for example "trim the intro off demo.mp4", "add subtitles to this clip", "make a 30-second cut", "put a title on it", "export the video".

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.
What the file says
# Oh My Cassette The `cassette` MCP server is a local bridge to the Cassette video editor. Its editing tools come from the Cassette MCP service and change as Cassette evolves, so this skill deliberately names none of them. **The server's instructions and each tool's description are the source of truth**: read them, and when they disagree with anything you remember, they win. ## Rules that hold for every version 1. **Follow the server.** Which tool to call, in what order, and how to route on a result are in the server instructions and the tool descriptions. Route on typed fields such as `status`, never on prose. 2. **Relay the user's words.** When a tool takes the user's editing request, pass it exactly as the user wrote it: no rewriting, summarizing, translating, or expanding. The Cassette agent reads the project media itself. 3. **Ground every claim in a tool result.** What is on the timeline, which version it is, and where the editor link points come from the latest result, not from memory. 4. **Render only when asked.** Export or render only when the user asks to export, render, download, or finish. …

How to install
mdr add cassette-editor/oh-my-cassette/cassette-video-edit@sha256:1d9a11a95f436042The line at the top of this page pins the label git:20261021.a1c53dc, 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.
