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

# Hallmark: working in this repo

Hallmark (crate `hallmark`, binary `hall`) is a local, agent-first development
loop. See [README.md](README.md) and [docs/DESIGN.md](docs/DESIGN.md). Decisions
are in [docs/decisions/](docs/decisions/), and the Claude Code behaviour they
rely on is in [docs/spikes.md](docs/spikes.md).

## Toolchain

The Rust toolchain (cargo, rustc, clippy, rustfmt, rust-analyzer) and `gh` come
from the Nix shell declared in `rig.toml`:

- with direnv: `direnv allow`, once;
- otherwise: `nix develop`, or `nix develop --command <cmd>`.

`gh` may not be on PATH outside the shell. It lives under
`/nix/store/*-gh-*/bin/gh`, and `hall` also honors `HALL_GH`.

## Commands

Run all three checks before calling anything done, and report their real output.

| What | Command |
| --- | --- |
| Build | `cargo build` |
| Test | `cargo test --all-targets` |
| Format check | `cargo fmt --check` |
| Lint | `cargo clippy --all-targets -- -D warnings` |
| Review snapshots | `cargo insta review` (or `INSTA_UPDATE=always cargo test`, then inspect the diff) |
| Run | `cargo run -- <args>`, e.g. `cargo run -- help --json` |

How to install

The exact contents, by fingerprint

mdr add tiagocolombo/hallmark/CLAUDE.md@sha256:8fe871f598dbb528

The line at the top of this page pins the label git:20261023.604a96c, 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.
