Claude Code Guide
The definitive zero-to-hero guide for Claude Code.
Who This Guide Is For
Whether you're a seasoned developer, a vibe coder building with AI, or someone who's never touched a terminal before, this guide meets you where you are. No programming experience required.
Chapters
Introduction & Getting Started
Learn how Claude Code's agentic loop works, install on macOS/Linux/Windows, explore the core tool set, and complete your first AI-assisted coding session.
Project Context & Memory
Master the CLAUDE.md hierarchy, auto-memory system, path-specific rules, and context window management to get dramatically better results from Claude Code.
Models, Cost Economics & Permissions
Choose between Sonnet, Opus, and Haiku for cost-effective AI coding. Configure effort levels, track spending, and set up the deny/ask/allow permission system.
Environment Sandboxing & Customization
Configure Claude Code's four-tier settings hierarchy, enable macOS Seatbelt or Linux sandbox isolation, and customize the terminal status line.
Remote Control & Headless Automation
Run Claude Code from any device via remote control, automate with headless mode in CI/CD pipelines, and schedule recurring tasks with cron.
Model Context Protocol
Connect Claude Code to external tools — databases, APIs, ticketing systems — using the Model Context Protocol with stdio, HTTP, and OAuth authentication.
Custom Skills
Build reusable SKILL.md files that encode team conventions as slash commands or auto-invoked capabilities, with tool restrictions and subagent isolation.
Hooks & Lifecycle Automation
Automate quality enforcement with 18 lifecycle events — lint before commits, block dangerous commands, and log every tool invocation to an audit system.
Git Worktrees & Subagent Delegation
Parallelize development across isolated git worktree branches using built-in and custom subagents with AGENT.md persona definitions.
Agent Teams & Advanced Orchestration
Coordinate multiple Claude Code instances on shared task lists with dependency tracking and peer-to-peer communication (research preview).
Security & Enterprise Administration
Deploy Claude Code at organizational scale with managed settings, permission governance, sandbox enforcement, and OpenTelemetry audit compliance.
