This repository contains the reconstructed source code of Claude Code (v2.1.88), Anthropic's official terminal-based AI coding assistant. It is a full-featured CLI application built on a custom Ink-based React renderer for terminal UI, with a sophisticated tool system, multi-agent orchestration (swarm/teammate modes), MCP (Model Context Protocol) integration, plugin marketplace, and enterprise management features. The architecture is modular: a core state management layer (createStore, signals), a tool abstraction (buildTool with Zod schemas, permissions, and UI rendering), a permission system with classifier-based auto-approval, and a terminal UI framework with Yoga layout, keyboard/focus management, and animation support. The application supports remote sessions via WebSocket bridge, scheduled tasks (cron), vim mode, computer use (macOS native), and extensive analytics/telemetry via Datadog, GrowthBook feature flags, and first-party event logging. External dependencies include the Anthropic API, AWS Bedrock/Vertex SDKs, MCP SDK, and various cloud provider SDKs. The codebase demonstrates high craftsmanship in state management patterns, tool orchestration, and terminal UI engineering, but also carries technical debt from feature flag proliferation, deprecated sync APIs, and ant-only code paths that complicate external reuse.
