Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# AGENTS.md

mARC (**Multi-Agent Relay Control**) is a Claude Code **plugin + self-marketplace**
that packages a portable, cross-repo AI engineering team: `@techlead` (channel
operator) convenes specialists `@dev`, `@sre`, `@design`, `@sec`, `@research`. The
team's
*governance* travels via one plugin; each consuming repo keeps its own facts.

**This repo is special: it is BOTH the product's source AND where the team dogfoods
on itself.** Self-improvement lessons legitimately flush to source *here* — the one
context where that is allowed (see Constraints).

## Architecture
- **Plugin** lives at `harnesses/claude-code/marc/`; the **marketplace** manifest is
  at repo root `.claude-plugin/marketplace.json` (name `nexaduo`, plugin `marc` →
  install `marc@nexaduo`, invoke `/marc:tech-lead`).
- **Leaders = skills** (`skills/<leader>/`, invoked `/marc:<leader>`); **specialists
  = a shared flat pool** (`agents/*.md`). Any leader convenes any specialist.
- Nesting under `harnesses/<harness>/` reserves the namespace for future non–Claude-Code
  harnesses. The growth model is in [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) —
  don't duplicate it here.

How to install

The exact contents, by fingerprint
mdr add nexaduo/marc/AGENTS.md@sha256:bd669de17c8cb850

The line at the top of this page pins the label git:20260830.7511183, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
