## Get Started in 60 Seconds

**Option A: One-liner** (no clone needed)
```bash
claude "Fetch and follow the onboarding instructions from: https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/tools/onboarding-prompt.md"
```

<details>
<summary>📸 <strong>Preview: Interactive Onboarding Flow</strong></summary>

## 5 Rules to Remember

1. **Review diffs** before accepting changes
2. **`/compact` at 70%** context usage (check with `/status`)
3. **Be specific**: WHAT + WHERE + HOW + VERIFY
4. **Plan Mode first** for risky/complex tasks (Shift+Tab×2)
5. **Create CLAUDE.md** for every project

## Choose Your Path

| I want to... | Go here |
|--------------|---------|
| Learn step by step | Run the onboarding command above |

## Why This Guide?

**The problem:**
- You scroll through awesome-lists → links, no learning path
- You read official docs → dense, no progression
- You search tutorials → scattered, outdated in weeks

**This guide:** Structured learning path with 49 copy-paste templates. Your mileage may vary—but this saves you the exploration time.

| Traditional Docs | This Guide |
|------------------|------------|
| Lists features | Teaches workflows |
| Reference lookup | Progressive learning |
| Theoretical concepts | Production-ready patterns |
| "Figure it out" | "Here's exactly how" |

**By [Florian BRUNIAUX](https://github.com/FlorianBruniaux)** | Founding Engineer [@Méthode Aristote](https://methode-aristote.fr) | [Connect on LinkedIn](https://www.linkedin.com/in/florian-bruniaux-43408b83/)

**Reading time**: Quick Start ~15 min. Full guide ~3 hours (most read by section).

> **If this guide saves you hours of trial-and-error, please star it.**

### Prerequisites

- **Node.js 18+** (or use the [shell installer](./guide/ultimate-guide.md#11-installation) on macOS/Linux)
- **Anthropic API key** — [Get one here](https://console.anthropic.com/)

---

### ⚡ Audit Your Setup

Already have Claude Code installed? Quickly scan your configuration:

```bash
curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/examples/scripts/audit-scan.sh | bash
```

**Instant checks**: Config files, tech stack, extensions, security hooks, MCP servers, CLAUDE.md quality

**Want deeper analysis?** Use [`tools/audit-prompt.md`](./tools/audit-prompt.md) for personalized recommendations (~3 min).

### 🤖 For AI Assistants

This guide is optimized for both human and AI consumption:

| Resource | Purpose | Tokens |
|----------|---------|--------|
| **[llms.txt](./machine-readable/llms.txt)** | Standard context file for AI crawlers | ~1K |
| **[reference.yaml](./machine-readable/reference.yaml)** | Structured index with line numbers | ~2K |

**Quick load** (paste in any AI assistant):
```bash
curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/machine-readable/reference.yaml
```

**Use cases**: Inject into ChatGPT/Claude/Gemini, add to system prompts, reference in Claude Code with `@machine-readable/reference.yaml`

**What's inside**: Decision trees, command reference, context zones, MCP servers, agent templates, troubleshooting—optimized for machine consumption. Points to line numbers in the [full guide](./guide/ultimate-guide.md) for deep dives.

### 🔬 Deep Audit (Personalized Recommendations)

Get a comprehensive, **context-aware** audit that analyzes your project's README, CLAUDE.md files, and business domain to provide tailored recommendations:

> 🔒 **Privacy**: The audit downloads reference files from this repo, then analyzes YOUR local files with your Claude CLI. Your project files are sent only to your Anthropic API endpoint, not to this repository or any third party.

**Quick Version** (~10 sec):
```bash
curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/examples/scripts/audit-scan.sh | bash -s -- --json | claude -p "Analyze this Claude Code setup. Give: 1) Health score 0-100 2) Top 3 quick wins 3) CLAUDE.md template for detected stack. Be concise."
```

**Full Audit with Context** (~30 sec, recommended):
```bash
# Claude Code Deep Audit - Context-Aware Version
# Downloads reference files, reads YOUR local files, analyzes with Claude
REF=$(curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/machine-readable/reference.yaml)
SCAN=$(curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/examples/scripts/audit-scan.sh | bash -s -- --json 2>/dev/null)
README_CONTENT=$(head -100 README.md 2>/dev/null || echo "No README.md found")
CLAUDE_MD=$(cat CLAUDE.md 2>/dev/null || echo "No CLAUDE.md found")
LOCAL_CLAUDE_MD=$(cat .claude/CLAUDE.md 2>/dev/null || echo "No .claude/CLAUDE.md found")

claude -p "Reference:
$REF

Scan results:
$SCAN

Project README (first 100 lines):
$README_CONTENT

Project CLAUDE.md:
$CLAUDE_MD

Local .claude/CLAUDE.md:
$LOCAL_CLAUDE_MD

IMPORTANT: Focus on INCREMENTAL improvements to existing setup. Don't suggest creating things that already exist. If CLAUDE.md exists, suggest specific improvements to it rather than a full rewrite.

Based on ALL this context, provide:
1. Stack Recap: runtime, framework, test runner, bundler, database, key integrations detected
2. Health Score (0-100) - be strict: penalize missing SSoT pattern if >100 lines without @refs
3. Findings table: Priority|Element|Status|Action (only gaps, not what exists)
4. Top 3 quick wins (<5 min) - MUST be specific to THIS project's domain (not generic advice)
5. If CLAUDE.md exists: list 3-5 specific improvements (not a full template). If missing: provide ~100 line template
6. Suggested agents/commands/hooks that DON'T duplicate existing ones - check extensions count first
7. Ideas to leverage Claude Code for this specific domain and detected integrations"
```

**What you get**:
- **Stack recap**: Runtime, framework, test runner, bundler, database, and key integrations auto-detected
- Strict health score (penalizes large CLAUDE.md without @refs)
- **Incremental improvements**: Specific fixes for YOUR setup, not generic advice
- Domain-aware suggestions (e.g., EdTech → session planning agents, E-commerce → inventory commands)
- Non-duplicate suggestions: Only recommends agents/commands you don't already have

**Want maximum depth?** Use [tools/audit-prompt.md](./tools/audit-prompt.md) with `claude --ultrathink`

What exit code should a PreToolUse hook return to BLOCK an operation?

  A) 0
  B) 1
  C) 2
  D) -1

? Your answer: A

✗ INCORRECT. The correct answer is C) 2

## 🔑 Golden Rules

Master these five principles before diving deeper:

1. **Always review diffs** before accepting changes — Claude suggests, you decide
2. **Use `/compact`** before context hits 70% — prevention beats recovery
3. **Be specific** in requests — Include WHAT, WHERE, HOW, VERIFY
4. **Start with Plan Mode** for risky/complex tasks — read-only exploration first
5. **Create CLAUDE.md** for every project — single source of truth

**Context Management Quick Reference**:

| Context % | Status | Action |
|-----------|--------|--------|
| 0-50% | Green | Work freely |
| 50-70% | Yellow | Be selective |
| 70-90% | Orange | `/compact` now |
| 90%+ | Red | `/clear` required |

> *These thresholds are based on my experience. Your optimal workflow may differ.*

## 🌍 About This Guide

### Our Philosophy

**Learning journey over reference manual.** We focus on:

- Understanding **why** before diving into **how**
- Real-world patterns you can use immediately
- Progressive complexity — start simple, master advanced at your pace
- Practical workflows over theoretical concepts

Think of this as **a structured learning companion** — not just documentation.

### Origins & Transparency

This guide is the result of several months of daily practice with Claude Code. I don't claim expertise—I'm sharing what I've learned to help peers and evangelize AI-assisted development best practices.
