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

# Repository Agent Guide

This flake manages NixOS hosts, macOS via nix-darwin, shared Home Manager profiles, and Colmena
deployments. Keep repository guidance here; the global rules and global skills shared across
projects live in [agents/](./agents/README.md).

## Where Changes Belong

- `flake.nix` defines inputs; `outputs/default.nix` composes outputs for `x86_64-linux`,
  `aarch64-linux`, and `aarch64-darwin`.
- `modules/` contains system modules; `home/` contains Home Manager modules. Put shared behavior
  here rather than duplicating it in host configurations.
- `hosts/` contains host-specific configuration; `outputs/<system>/src/` wires hosts into outputs.
- `vars/` and `lib/` provide shared values and helpers. Use `myvars` and existing abstractions
  instead of hardcoding usernames or paths.
- `secrets/` contains agenix definitions. The encrypted `.age` files live in the private
  `~/codes/nix-secrets` repository, never in this public one — never copy a `.age` file here. Use
  the `nix-config-secrets` skill.
- `overlays/` and `hardening/` hold package overlays and hardened (nixpak/bwrap) wrappers.

How to install

The exact contents, by fingerprint
mdr add ryan4yin/nix-config/AGENTS.md@sha256:684e9ceb9d03b358

The line at the top of this page pins the label git:20261014.72a7a2a, 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.
