Claude Code Quick-Start Playbook

Module 1: How Claude Code Actually Works

Before your team can use Claude Code well, they need to understand what it is — and what it isn't. This module gets everyone on the same page in 10 minutes.

What Claude Code is

Claude Code is an AI pair programmer that lives in your terminal. You describe what you want in plain English. It reads your actual codebase, writes code, runs commands, and shows you the diff before applying anything.

Unlike a chatbot (where you paste code back and forth), Claude Code has direct access to your files. It can read your project structure, understand how your modules relate to each other, and write code that actually fits your existing patterns.

What it is not

• It is not a replacement for code review. It writes code fast. It can write wrong code fast. Your review process stays.
• It is not magic. Vague instructions get vague results. The better your prompt, the better the output.
• It is not always right. Claude Code will confidently write code that doesn't compile. Verify before you ship.

First-time setup (takes 5 minutes)

That's it. Claude Code reads your project structure automatically. No configuration file required to get started.

Module 2: The Five Prompts Every Developer Needs

Most developers undersell Claude Code's capabilities in the first week because they use it like a chatbot. These five prompt patterns — used daily — unlock the majority of its value.

1. The "explain and fix" prompt

Use this when you hit an error you don't immediately understand. Don't just paste the error — ask for the explanation AND the fix together.

2. The "implement this pattern" prompt

Use this when you need a new feature that follows your existing code style. Give Claude Code a reference file so it matches your patterns.

3. The "review this diff" prompt

Before you open a PR, have Claude Code review your own changes. It catches things you're too close to see.

4. The "write the tests" prompt

Claude Code is especially good at test generation because it can read your existing tests and match the format exactly.

5. The "refactor for readability" prompt

Useful for cleaning up complex functions without changing behavior. Always ask Claude Code to explain what changed and why.

Module 3: The 30-Day Adoption Plan

The teams that get the most out of Claude Code don't adopt it all at once. They follow a deliberate ramp. Here's the plan we give every team.

Week 1: Low-stakes tasks only

In the first week, every developer uses Claude Code only for tasks where a mistake is cheap to catch: writing tests, adding docstrings, small utility functions. The goal is building familiarity and learning the team's prompt patterns.

• Write tests for existing functions
• Add JSDoc or inline comments to old code
• Draft README updates
• Generate boilerplate (new route, new model, new component)

Week 2: Introduce it to code review

In week two, developers start using Claude Code as a pre-review step before opening a PR. Ask it to review your own diff before requesting a human review. This reduces review cycles and catches obvious issues before a teammate has to.

Week 3: Tackle backlog debt

By week three, developers have enough confidence to use Claude Code on harder problems: refactoring legacy code, migrating from one library to another, addressing tech debt items that have been on the backlog for months. The key is still: review everything before it merges.

Week 4: Set team standards

At the end of week four, the team meets for 30 minutes and documents their own "prompt patterns that work" — what prompts got good results, what got bad results, and any areas where Claude Code shouldn't be used without extra review. This document becomes the team's playbook going forward.
