English · 中文 --- [!TIP] How this was built: Read the Distilling Claude Code Source — A Harness Engineering Practice Log for the full story of how Codex and Claude Code collaborated, the PCA-inspired taste injection, and what worked (and didn't). The model loop is easy. User - LLM - tool use - execute - loop fits on a napkin. What makes a production agent actually work — reliably, safely, at scale — is everything around the loop: memory that persists across sessions, permissions that fail closed, context budgets that don't explode, multi-agent coordination that doesn't collapse into chaos, and extensibility that doesn't become a security hole. Anthropic calls this the harness . This repo teaches you how to build one. [!NOTE] This skill is compatible with the open agent skills ecosystem. Install with npx skills add — works with Claude Code, Codex, and 40+ other agents. What This Is 6 design-pattern chapters and 11 deep-dive references, extracted from systematic source-level analysis of the Claude Code runtime — the production AI coding agent behind Claude's 512,000-line TypeScript codebase. [!IMPORTANT] This is not a code dump or a source mirror. Every pattern is expressed as a portable, runtime-agnostic design principle. Claude Code is used as grounding evidence, not as the only possible implementation. If you're building an agent on a different stack, these patterns still apply.
