Claude Code CLI Commands Beginner’s Guide
This developer handbook compiles the Claude Code command-line interface (CLI) reference into a practical cheat sheet for new users. It documents installation and login steps, session commands (e.g., claude, claude -p, claude -c), CLI flags (e.g., --model, --effort, --output-format, --max-budget-usd, --chrome), in-session slash commands (e.g., /help, /clear, /compact, /debug, /code-review) and in-prompt syntax for file references and shell execution (e.g., @./path, !shell-command). The article includes examples, expected outputs, and workflow tips for background sessions, permissions, and tooling integrations (MCP servers, Chrome automation). The post credits Claude as the original source of the cheat sheet and cites Claude Code official documentation. Publication date: 2026-06-01.
Practical CLI documentation for Anthropic's Claude Code aids developer productivity but has limited immediate impact on the broader AdTech/MarTech industry.

CLAUDE.md: Guide to Configuring Claude Code
This DEV.to tutorial (published 2026-06-21) explains CLAUDE.md, a small markdown file that Claude Code reads at the start of every session to provide project-specific context. The article describes what to include (stack with versions, directory map, build/test commands, conventions, generated files), where to put it (project root), and how to bootstrap it using Claude Code's /init command. The author argues a concise, accurate CLAUDE.md compounds value across sessions and links to a free quick-start cheat sheet plus a paid, deeper Gumroad guide covering hooks, subagents, commands, skills and plugins.
Anthropic's Claude Code: Beginner's Guide
This guide explains Claude Code, an agentic coding tool from Anthropic that runs in the terminal, reads entire codebases, executes commands (bash, npm, git), and can modify files with permission. The article covers installation on macOS/Linux and Windows (native installer, Homebrew, WinGet), authentication options (Claude subscriptions or enterprise connectors like Amazon Bedrock, Google Vertex AI, Microsoft Foundry), permission modes (Normal, Auto, Plan), built-in tools (read, edit, bash, grep, glob, web), context management (approx. 200,000-token context window), CLAUDE.md and Auto Memory for persistent project instructions, CLI commands and workflows for React developers, and pricing tiers tied to Claude subscriptions (Pro, Max, API pay-as-you-go). The guide includes best practices for prompting, testing, Git integration and tips for efficient token usage.
Developer First Look: Anthropic's Claude Code
This developer-first look examines Claude Code, Anthropic's terminal-based, agentic coding tool. Unlike chat interfaces, Claude Code reads project folders, edits and creates files, runs shell commands, and preserves project context via a CLAUDE.md briefing file. The author walks through installation, trust prompts and permission modes (Default, Auto-Accept Edits, Plan), model selection (example: claude-haiku-4-5), and configuration commands (/model, /config). Key features highlighted include an @ folder reference system for pulling content from project files, session tools (/cost and /context) for monitoring tokens and spending, and a permission workflow that proposes diffs before applying changes. The tutorial builds a portfolio site almost entirely with Claude Code at a reported cost under $0.10 and notes best practices for scoping the tool to a project folder and using CLAUDE.md for team conventions.
