elevenlabs-voice skillA

elevenlabs-voice is agent-read markdown (skill) from vellum-ai/vellum-assistant: Select and tune an ElevenLabs TTS voice - curated voice list, custom/cloned voices via API key, and tuning parameters.

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

Latest version
mdr add vellum-ai/vellum-assistant/elevenlabs-voice@git:20260723.18b8bbb
Exact content
mdr add vellum-ai/vellum-assistant/elevenlabs-voice@sha256:f5b305d5b0d5dd4e

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.
