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.

## Project Overview

Groundwork is a Claude Code plugin that provides a skills library for structured development workflows. It contains 40 skills spanning the full lifecycle — discovery, domain modeling, architecture, planning, TDD, debugging, validation, and shipping. Every capability is a skill; there is no separate commands layer (skills are both user-invocable via `/groundwork:<name>` and, where appropriate, model-invocable).

The `using-groundwork` skill is the **lifecycle router**: it maps work → skill across every phase and is the only way the model can surface user-only leaves (which are invisible to it at call time). When authoring or editing a skill, see `docs/developing-skills.md` (contributor guide: anatomy, frontmatter, tier selection, authoring discipline, progressive disclosure).

## Project Structure

This is a **Claude Code plugin**, not a traditional software project. There is no build step for Claude Code use. A separate installer (`install-skills.sh`) *exports* the skills to other AI coding harnesses (see "Multi-target installation" below).

How to install

The exact contents, by fingerprint
mdr add etr/groundwork/CLAUDE.md@sha256:366ba1aa2941ec18

The line at the top of this page pins the label git:20260913.a08ec3f, 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.
