Claude Code is fast to install and slow to get good at, because nothing tells you what to ask for, what to keep out of a session, or why the same request works one day and wanders the next. This pack is the missing first week: how the tool actually thinks, what to do in your first hour, and twelve workflows with the exact text to send.It is one file you read, not software you run. Inside: a working model of how Claude Code reads a repository and why that differs from a chat window, a complete CLAUDE.md example you can copy into your project root and fill in, twelve workflows covering unfamiliar code, features, debugging, tests, refactors, review, migrations, dependencies, commits, documentation, a failing CI build and one off scripts, each with when to use it and what you should get back, plus the rules that keep a session on rails and the mistakes that cost the most time.One file, one payment. Keep it open beside your terminal for as long as you use Claude Code. No subscription, no account, no seat licence.
