Claude Code Tutorial: How to Install and Use Claude Code

On this page

Claude Code is Anthropic's official agentic developer environment engineered to read, edit, execute, test, and maintain software projects directly within command-line interfaces, editor extensions, desktop tools, and web environments. Unlike passive completion engines or chat widgets, Claude Code operates as an autonomous engineering partner capable of executing shell scripts, navigating complex directory trees, running automated test suites, and orchestrating Git workflows within local workspaces.

For developers advancing their careers through Commit Career courses or building production systems, mastering agentic tooling is essential. This tutorial provides a comprehensive technical breakdown for installing, configuring, and deploying Claude Code across macOS, Windows, Linux, WSL, VS Code, and specialized CMS environments like WordPress.

What Is Claude Code?

Claude Code is an agentic software development tool created by Anthropic that interacts natively with project repositories through terminal sessions, editor plugins, and cloud environments.

To understand its position in the developer ecosystem, it is important to distinguish between "Claude Code" and broader industry terms such as "Claude coding," "coding with Claude," or "Claude AI for coding". General Claude coding refers to using Anthropic's language models for programming tasks, such as copying code blocks out of the web chat interface or calling the raw API. Claude Code explicitly denotes the standalone agentic developer environment built by Anthropic to interact directly with local file systems, command shells, build chains, and version control repositories.

How Claude Code Works

Claude Code operates through a continuous agentic loop rather than a single response generation turn:

  1. Context Discovery: It scans your repository root, reads configuration files like CLAUDE.md, and builds an internal map of project dependencies and architectural patterns.

  2. Task Planning: It analyzes user prompts, determines required file edits, and determines necessary build steps or terminal commands.

  3. Autonomous Execution: It edits code across multiple directories, creates or renames files, and executes terminal commands directly in your environment.

  4. Validation and Error Recovery: It executes local test suites, captures stack traces from failed builds, and diagnoses runtime errors to apply self-correcting fixes.

  5. Version Control: It stages changes, generates descriptive commit messages, and prepares pull requests.

  2. Markdown

# WordPress Project Guidelines

- Follow WordPress Coding Standards for PHP and JavaScript.

- Always sanitize inputs with sanitize_text_field() or absint().

- Escape all outputs using esc_html(), esc_attr(), or esc_url().

- Use WP-CLI for database migrations and testing (wp plugin list, wp option get).

Using Claude Code to Build and Modify WordPress Themes

Claude Code can construct custom block themes, create theme.json configurations, generate Gutenberg block patterns, and refactor PHP template files:

Plaintext

Create a custom PHP template file template-parts/content-hero.php. Include responsive ACF (Advanced Custom Fields) fields for a title, subtitle, and CTA button, adhering strictly to WordPress escaping functions.

Using Claude Code With WordPress Plugins

You can use Claude Code to build custom WordPress plugins from scratch or add REST API endpoints:

Plaintext

Scaffold a custom WordPress plugin in wp-content/plugins/lead-capture. Create a custom REST API route at /wp-json/lead-capture/v1/submit that accepts POST requests, validates nonces, sanitizes input data, and inserts records into a custom DB table using $wpdb.

WordPress Development Workflow With Claude Code

  1. Local Shell Integration: Run WP-CLI operations directly through Claude Code using Bash mode (!wp cache flush or !wp core version).

  2. Automated PHPCS Testing: Command Claude Code to run PHP CodeSniffer against WordPress standards (!vendor/bin/phpcs --standard=WordPress .).

Claude Code Hook Lifecycle Events

  • SessionStart: Triggers when an agent session initializes or resumes.

  • PreToolUse: Triggers after tool inputs are generated but before execution. Can approve, alter, or block the tool call.

  • PostToolUse: Triggers immediately after a tool call finishes execution.

  • Stop: Triggers when the agent completes its main task loop.

Creating a Guardrail Hook

Guardrail hooks prevent Claude Code from running dangerous operations, such as deleting critical files or executing unsafe shell scripts.

Claude Code Hooks Configuration

Add your hook definition to .claude/settings.json inside your project or home directory:

JSON

{

  "hooks": {

    "PreToolUse": [

      {

        "matcher": "Bash",

        "hooks": [

          {

            "type": "command",

            "command": ".claude/hooks/block-destructive.sh"

          }

        ]

      }

    ]

  }

}

Example: Blocking Destructive Commands

Create the executable script .claude/hooks/block-destructive.sh:

Bash

#!/bin/bash

# Read tool input from stdin via jq

COMMAND=$(jq -r '.tool_input.command')

# Check for destructive command patterns

if echo "$COMMAND" | grep -qE 'rm -rf|drop table|git reset --hard'; then

  jq -n '{

    hookSpecificOutput: {

      hookEventName: "PreToolUse",

      permissionDecision: "deny",

      permissionDecisionReason: "Blocked by safety hook: Destructive shell command detected."

    }

  }'

else

  exit 0

fi

Make the script executable:

Bash

chmod +x .claude/hooks/block-destructive.sh
