What problem does it solve?
Claude Code accelerates feature implementation, refactoring, and review-ready code changes by delegating the full coding workflow to an autonomous CLI agent instead of doing everything manually.
Core Features & Use Cases
- Non-interactive print mode (-p): Run one-shot coding tasks and get results back immediately for automation and CI-style workflows.
- Interactive PTY sessions (tmux): Keep a multi-turn agentic coding loop with real-time progress and follow-up iterations like refactor → review → fix → tests.
- Structured outputs (json/stream-json) and session resumption: Capture deterministic results, track turns/cost, and resume work using session IDs when tasks span multiple steps.
Quick Start
Ask an AI to delegate a bugfix to Claude Code in print mode for your project directory, then return the patch and instructions to verify it.
