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 p","default_branch":null,"files":null,"tree":[],"storefront":"/r/walkinglabs","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/walkinglabs/learn-harness-engineering/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
