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

# CLAUDE.md

macOS dev environment automation: dotfiles, AI agent configs, skills, and dev stacks.

## Commands

Run `make help` to list targets and `hal --help` for the CLI.

Use `make` targets instead of running the underlying commands directly. They chain the right tools with the right flags.

## Gotchas

- **Edit under `dotfiles/`, never under `~/`**: `hal sync` symlinks every `links` entry in `dotfiles/hal_dotfiles.json` into `~/`, so an edit to a linked path is live immediately. A new file outside a linked directory needs its own entry plus `hal sync` before anything references it.
- **Mirror `dotfiles/.claude/settings.json` edits into `dotfiles/.claude/settings.sandbox.json`**: the sandbox copy is the settings for Claude Code under blackwall and drifts otherwise. Skip what it leaves out on purpose: hooks, the `ask` list, host-path `deny` rules, Ollama-backed plugins and env vars, and its own theme and statusline paths.

How to install

The exact contents, by fingerprint
mdr add vinta/hal-9000/CLAUDE.md@sha256:a98254408f71092c

The line at the top of this page pins the label git:20261007.23243bf, 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.
