Individual skill

cassette-video-edit

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". Drives the tools of the `cassette` MCP server (oh-my-cassette), which relays a running conversation with the Cassette editing agent.

# 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
