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

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## What this repo is

`rails-hyperdrive` is a **dev-only Rails engine gem** that mounts an MCP (Model Context Protocol) server at `/_hyperdrive/mcp` exposing 8 introspection tools for AI coding agents, plus `hyperdrive:init` / `hyperdrive:sync` generators that discover and install four artifact kinds — **skills** (lazy), **guidelines** (eager), **agents** (Claude Code subagents), and **commands** (slash commands) — shipped by companion gems under a documented contract, and a networked `hyperdrive:discover` that suggests uninstalled companion gems for the app's stack from rubygems.

**rails-hyperdrive is the mechanism; companion gems (`rails-hyperdrive-<library>`) are the content.** The gem ships no skills or guidelines of its own — only the contract and the discovery/install engine.

This is the gem itself, **not** an app that uses it. There is no host Rails app — specs boot a tiny in-memory app via Combustion at `spec/internal/`.

`README.md` describes the user-facing golden path.

How to install

The exact contents, by fingerprint
mdr add rails-hyperdrive/rails-hyperdrive/CLAUDE.md@sha256:1e8e21e7f9875ded

The line at the top of this page pins the label git:20260908.ef1b503, 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.
