voice-agent skillA

voice-agent is agent-read markdown (skill) from vanducng/skills: Operate the `vac` CLI for Retell voice AI - bounded reads and explicitly authorized writes over agents, prompts, tools, tests, calls, transcripts, chats, phone numbers, voices, flows, knowledge bases, and exports. Use when the user mentions `vac` or Retell, asks to list/create/update voice agents, numbers, or flows, diagnose a call or transcription, or export call data..

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 vanducng/skills/voice-agent@v0.4.0
Exact content
mdr add vanducng/skills/voice-agent@sha256:5eb995fe8d00cdb4

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.
