This skill should be used when the user mentions "setup", "getting started", "install dependencies", "dev environment", "onboarding", "won't run", "version mismatch", "devcontainer", "env vars", "works on my machine", or a failing local install/build. It maps where a repo declares its runtime needs and how to diagnose and fix the common setup failures that block a green build on day one.

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

# Setup Diagnosis

## Purpose
The biggest day-one sink is getting a green build: missing dependencies, the wrong runtime version, OS-specific breakage, missing env vars, and silently outdated README steps. This skill provides two things, a **map of where a repo declares what it needs** (so you stop guessing) and a **catalog of the common failure modes and their fixes**: so bootstrapping becomes detect → run → diagnose → verify, not trial and error.

## Principle: read the declared requirements, don't guess
A repo almost always tells you what it needs, in machine-readable files. Trust those over prose READMEs, which drift. Reconcile pins across files before running anything.

## Where requirements live (quick map)
| Need | Look in |
|------|---------|
| Runtime version | `.nvmrc`, `.tool-versions`, `mise.toml`, `.python-version`, `.ruby-version`, `engines`, `go.mod`, `<java.version>` |
| Package manager | `packageManager` field, lockfile kind, `Gemfile`/`poetry.lock`/`Pipfile.lock` |
| Dependencies | `package.json`, `pyproject.toml`/`requirements*.txt`, `Gemfile`, `go.mod`, `pom.xml`/`build.gradle`, `Cargo.toml` |

How to install

The exact contents, by fingerprint
mdr add sigistry/marketplace/setup-diagnosis@sha256:ec5ce23dd08be2b1

The line at the top of this page pins the label git:20260826.571bc2f, 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.
