init skillA

init is agent-read markdown (skill) from nexaduo/marc: Opt-in onboarding for the mARC agent team. Scaffolds a per-repo team binding so the team graduates from ephemeral session-memory to persistent, versioned config — without ever writing a file silently. Discovers the repo's org/repo/ project at runtime via `gh`, prefills `.agents/team.toml`, and (optionally) a lean `AGENTS.md` skeleton and the `enabledPlugins` pin in `.github/copilot/settings.json`. Each artifact is independently opt-in and is shown to you before anything is written. Invoke with /.

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 nexaduo/marc/init@git:20260805.c6a201d
Exact content
mdr add nexaduo/marc/init@sha256:cd2b13b5175df197

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.
