# Claude Code

Anthropic's agentic coding tool combining autonomous planning, execution, and validation with extensibility through skills, plugins, MCP servers, and hooks.

## Core Concepts

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

**Agent Skills**: Modular capabilities with SKILL.md + bundled resources (scripts, references, assets) loaded progressively

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

**Hooks**: Event-driven shell commands (SessionStart, PreToolUse, PostToolUse, Stop, SubagentStop)

**MCP Servers**: Model Context Protocol integrations for external tools (GitHub, Jira, databases)

**Plugins**: Packaged collections distributed via marketplace
