What this skill does
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 Repository Structure Reading Routes ⚡ Quick Route (7 articles) — Global understanding 🤖 AI Engineering Route (9 articles) — Deep AI core 📚 Complete Route (25 articles) Read docs/01 through docs/25 in order. Key Patterns Extracted from Claude Code 1. Tool Builder Pattern (buildTool()) Claude Code registers tools using a builder with three-layer conditional registration: 2. AsyncGenerator Conversation Loop (docs/05) 3. 35-Line Minimal Store (React ↔ Non-React Bridge) (docs/03) 4. System Prompt Segmented Construction (docs/04) 5. Context Auto-Compact with Token Budget (docs/06) 6. Permission 7-Step Decision Pipeline (docs/16) 7. Multi-Agent Context Isolation (docs/12) 8. withRetry for API Overload (docs/20) Applying These Patterns to Your Own Agent Minimal Agent Scaffold Thinking / Extended Reasoning Config (docs/08) Troubleshooting Problem Solution --- --- Article links 404 Clone the repo — all articles are in docs/ locally Code examples reference internal modules They're illustrative patterns extracted from analysis, not runnable as-is Need the actual Claude Code source See Anthropic's published CLI source Want to contribute an article Open a PR to docs/ following the existing article format Start Here
