# Claude Code Expert

Claude Code is Anthropic's agentic coding tool that lives in the terminal and helps turn ideas into code faster. It combines autonomous planning, execution, and validation with extensibility through skills, plugins, MCP servers, and hooks.

## When to Use This Skill

Use when users need help with:
- Understanding Claude Code features and capabilities
- Installation, setup, and authentication
- Using slash commands for development workflows
- Creating or managing Agent Skills
- Configuring MCP servers for external tool integration
- Setting up hooks and plugins
- Troubleshooting Claude Code issues
- Enterprise deployment (SSO, sandboxing, monitoring)
- IDE integration (VS Code, JetBrains)
- CI/CD integration (GitHub Actions, GitLab)
- Advanced features (extended thinking, caching, checkpointing)
- Cost tracking and optimization

**Activation examples:**
- "How do I use Claude Code?"
- "What slash commands are available?"
- "How to set up MCP servers?"
- "Create a new skill for X"
- "Fix Claude Code authentication issues"
- "Deploy Claude Code in enterprise environment"

## Core Architecture

**Subagents**: Specialized AI agents (planner, code-reviewer, tester, debugger, docs-manager, ui-ux-designer, database-admin, etc.)

**Agent Skills**: Modular capabilities with instructions, metadata, and resources that Claude uses automatically

**Slash Commands**: User-defined operations in `.claude/commands/` that expand to prompts

**Hooks**: Shell commands executing in response to events (pre/post-tool, user-prompt-submit)

**MCP Servers**: Model Context Protocol integrations connecting external tools and services

**Plugins**: Packaged collections of commands, skills, hooks, and MCP servers
