demo-voiceover skillA

demo-voiceover is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Generates demo narration with the ElevenLabs MCP server — one audio file per storyboard section, measured so the editor can cut picture to voice. Covers voice and model selection for product demos, fitting a line to a target duration, pronunciation of product names, optional word-level caption alignment, and music beds. Use at the voiceover stage of a demo video, when regenerating narration, or when changing the narrator..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
