README

The Claude Code Operating Model — Code Examples

Companion repository for **_The Claude Code Operating Model_** (Packt, 2026) by **Jia Huang** — *Build scalable AI coding systems with Skills, MCP, Hooks, agent orchestration, and SDK patterns.*

Every chapter has a directory here. The code is runnable, and it reflects the **corrected** APIs as of publication — where the printed text and the current SDK disagree, this repository is right.
