This skill should be used when the user asks to "set up my development environment", "configure my tools", "install development tools", "set up for the AI Primer", "get started with the primer", or mentions needing to set up Node.js, Git, Wrangler, MCP servers, or Cloudflare for the first time. Guides complete beginners through one-time environment setup for full-stack AI product development.
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.

# Primer Setup ## Overview One-time guided setup for the AI Primer workflow. Designed for users who may have never opened a terminal. Progressive: present one step at a time, confirm before acting, verify after each change. Idempotent: detect what is already installed and skip completed steps. Safe to re-run at any point — nothing gets duplicated or overwritten. This skill complements the AI Primer guidebook (Parts 2-3) and prepares the user's machine with every tool, connection, and configuration needed to build and ship full-stack products with Claude. --- ## Design Principles Five principles govern how this setup operates. Follow all of them throughout the process. ### Never assume terminal familiarity Explain every concept in plain English before executing any command. When a command runs, describe what it does and what the output means. Treat the terminal as a new environment the user is seeing for the first time. Avoid jargon; when technical terms are unavoidable, define them immediately. ### One step at a time …

How to install
mdr add ammonhaggerty/a-primer-skills/primer-setup@sha256:bf546249e4f18518The line at the top of this page pins the label git:20261012.7c2872f, 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.
