Learn Harness Engineering A project-based course on building the environment, state management, verification, and control mechanisms that make AI coding agents work reliably. 🌍 This course is available in **15 languages**: English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Русский, Deutsch, العربية, Tiếng Việt, Oʻzbekcha, Türkçe, Portuguese (BR), Українська. Choose your language from the badges above. 🆕 What's New — August 2026 Frontier Harness Design Breakdowns — new section (4 breakdowns)** What | Details | **New section** | Frontier Harness Design Breakdowns — Apply the course's five-subsystem framework (instructions, tools, environment, state, feedback) to reverse-engineer how four frontier products build real harnesses. | **Pi** | How Pi builds its harness — a minimal kernel, programmable expansion, and context engineering behind "ask Pi to build what you want." | **Claude Code** | How Claude Code builds its harness — four-layer memory, five-level compaction, hooks, and sub-agent isolation. | **Codex** | How Codex builds its harness — the repository as source of truth, AGENTS.md as a directory page, and worktree isolation. | **DeepSeek** | How DeepSeek builds its harness — "everything is a plugin," capability seams, and an event pipeline. | **All 15 languages** | Full translation coverage across all supported languages. | Key idea:** The course gives you a framework; these breakdowns show you how the same principles actually play out in production harnesses. Graph Engineering Update — 1 new lecture, 1 new project** What | Details | **Lecture 14** | From Single Loops to Graph Engineering — Why a single loop grows into a graph: the four stacked layers (prompt → context → loop → graph) and where harness sits in that stack, the four parts of a graph (nodes, edges, share
