About This Guide

This guide is the result of several months of daily practice and research with Claude Code, Anthropic's AI coding assistant CLI. Whether you're exploring agentic development, LLM-powered coding workflows, or AI pair programming, this resource covers everything from basic setup to advanced MCP server orchestration.

I don't claim to be an "expert" — I'm simply sharing what I've learned along the way, humbly hoping to help my peers and evangelize good practices in AI-assisted development.

A significant source of inspiration for this work was Claudelog.com, which I highly recommend for anyone wanting to go deeper.

Important note: This guide was largely generated with the help of AI. As such, it likely contains errors, inaccuracies, or outdated information. I would be delighted to receive any feedback, corrections, or — even better — pull requests to improve it. Don't hesitate to open an issue or submit a PR!

⚠️ WINDOWS USERS - IMPORTANT DISCLAIMER

I work on macOS and have not personally tested Windows-specific commands (PowerShell, batch files, path syntax).

What this means for you:

• PowerShell scripts are AI-generated and may need adjustment
• Path separators (\ vs /) may be incorrect in some examples
• Batch file hooks may require debugging
• Git Bash commands should work as-is (they use Unix syntax)

How you can help:

1. Open an issue if you find Windows-specific problems
2. Submit a PR with corrections (Windows testers highly appreciated!)
3. Join our community discussions to share Windows-specific tips

Status: We are actively seeking Windows contributors to improve platform support.

Language: I wrote this guide in English by default to reach a wider audience, but French is my native language. I could easily translate it to French myself, or leverage AI and community contributions for other languages. Let me know if translations would be useful!

If you find value in this guide, have questions, or want to discuss Claude Code practices, feel free to reach out on LinkedIn.

Quick Start

# Install Claude Code (all platforms)
npm install -g @anthropic-ai/claude-code

# Or on macOS/Linux only:
curl -fsSL https://claude.ai/install.sh | sh

# Start in your project
cd your-project
claude

Windows Users: Use %USERPROFILE%\.claude\ instead of ~/.claude/ for all paths in this guide.

The 7 Commands You Need

Command	Action
/help	Show all commands
/status	Check context usage
/compact	Compress context (>70%)
/clear	Fresh start
/plan	Safe read-only mode
/rewind	Undo changes
Ctrl+C	Cancel operation

Context Management (Critical!)

Context %	Action
0-50%	Work freely
50-70%	Be selective
70-90%	/compact now
90%+	/clear required

---

The Golden Rules

1. Always review diffs before accepting changes
2. Use /compact before context gets critical (>70%)
3. Be specific in requests (WHAT, WHERE, HOW, VERIFY)
4. Start with Plan Mode for complex/risky tasks
5. Create CLAUDE.md for every project
