techNmak highlights Learn Harness Engineering, a free MIT-licensed open-source course by Walking Labs with 14 lectures, 8 hands-on projects, and 15 language samples, referencing OpenAI and Anthropic harness engineering writeups. It covers agent instructions (AGENTS.md/CLAUDE.md), context management and persistent memory, multi-session continuity, task boundaries, testing/verification/observability, automated agent loops, and multi-agent orchestration. Projects build a complete agent harness comparing prompt-only vs structured workflows, with ready-to-use templates, verification scripts, and a harness-creator skill.
