Why This Guide Exists

The Problem: Most Claude Code resources are either scattered blog posts or dense reference manuals. You're left piecing together workflows, guessing at best practices, and discovering critical concepts too late.

Our Solution: A structured learning journey that takes you from installation to advanced orchestration in hours, not weeks—with ready-to-use examples you can deploy immediately.

What Makes This Different

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

Your Investment: 45 minutes to productivity. 2 hours to mastery. 8500+ lines organized by learning path, not alphabetically.

If this guide saves you hours of trial-and-error, please star it. Your support helps others discover this resource and motivates continued updates.

Prerequisites

• Node.js 18+ (or use the shell installer on macOS/Linux)
• Anthropic API key — Get one here
• ~$5-20/month typical usage cost (varies with usage intensity)

⚡ Audit Your Setup

Already have Claude Code installed? Scan your configuration in 2 seconds:

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 claude-setup-audit-prompt.md for personalized recommendations (~3 min).

🤖 LLM Reference

Give any AI assistant instant Claude Code expertise (~2K tokens):

curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/claude-code-reference.yaml

Use cases: Paste output into ChatGPT/Claude/Gemini, add to system prompts, or reference in Claude Code with @claude-code-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 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: Everything runs locally on your machine. The script only downloads reference files from this repo—your project files (README, CLAUDE.md) are read locally and sent only to your own Claude CLI. Nothing is sent back to this repository or any third party.

Quick Version (~10 sec):

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):

# Claude Code Deep Audit - Context-Aware Version
# Downloads reference files, reads YOUR local files, analyzes with Claude
REF=$(curl -sL https://raw.githubusercontent.com/FlorianBruniaux/claude-code-ultimate-guide/main/claude-code-reference.yaml)
SCAN=$(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

🔑 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
