What It Does

Claude Code is Anthropic’s agentic coding tool that runs in your terminal. It can read your entire codebase, edit files, run commands, search the web, and manage git operations — all through natural language conversation.

Key Strengths

• Deep reasoning: Claude’s extended thinking enables complex multi-step coding tasks
• Agentic workflow: Can autonomously plan, implement, test, and iterate
• MCP support: Connects to external tools via Model Context Protocol
• Skills system: Reusable .claude/skills/ with SKILL.md files
• Git-native: Built-in git operations, PR creation, code review
