Claude Code Source Study

This is a 25-article Chinese-language teardown of Claude Code's actual source, covering the ~1900 files behind Anthropic's CLI agent. You get line-by-line analysis of the system prompt construction, the AsyncGenerator conversation loop, the 35-line reactive store bridging React and imperative code, the 7-step permission pipeline, and the token budget auto-compaction logic. If you're building a production AI agent and want to see how Anthropic handles tool registration, context management, and terminal UI with Ink, this is the annotated walkthrough. It's study notes, not documentation, so expect references to specific files and extracted patterns you can lift into your own projects.

Claude Code Source Study

Skill by ara.so — Daily 2026 Skills collection.

A 25-article deep-dive into Claude Code's ~1900-file source code, covering System Prompt engineering, multi-agent orchestration, tool systems, permission security, and terminal UI. Learn production-grade AI agent patterns from Anthropic's real CLI product.

What This Project Is

This is a Chinese-language source code analysis series that dissects Claude Code (Anthropic's AI CLI coding assistant) module by module — with exact file references, line numbers, and code snippets. Each article extracts reusable design patterns for building your own AI agent applications.

Tech stack covered: Bun + TypeScript + Ink (React for terminals) + Anthropic API
