Three steps to turn Claude Code from a chat window into the system everything else sits on top of. Not a feature tour. The install, the prompts that work, and the one file that makes every session 10x better.
The Problem Nobody Talks About
Every time you open Claude Code, you start from zero. No memory of your project. No knowledge of your conventions. No awareness of which files matter and which to ignore. You spend the first five minutes of every session re-explaining who you are and what you're working on.
Multiply that across ten sessions a day. That's fifty minutes of repeated setup. Every single day.
Three steps fix this. Install. Prompts. CLAUDE.md. You set it up once. Claude follows it every time.
Why This Changes Everything
- Setup once, run forever. The kit you build today saves time on every session for the next two years. It compounds.
- Persistent memory built in.
CLAUDE.mdanchors per-project context so the agent stops forgetting your conventions, your file structure, and your rules. - Open standard. Skills,
CLAUDE.md, and the prompt patterns in this guide work in Claude Code, Cursor, Codex, Copilot, and Gemini CLI. Build the kit once, use it everywhere.
Step 1: Install Claude Code
Run this in your terminal:
npm install -g @anthropic-ai/claude-codeThen claude to launch. First run prompts you to log in to Anthropic. Twenty dollars a month for Claude Pro, which bundles Claude Code with it.
Once you're in, you have an AI coding agent in your terminal that can read your files, run commands, edit code, and commit changes. The next two steps turn it from a generic assistant into something that actually knows your project.
