Prompt engineering. Context engineering. Now harness engineering. That's the evolution for AI coding and it's happening fast! A harness is the system around the coding agent - the thing that turns "manually shepherding an agent through the same 8 steps every day" into "run one command and it handles everything." Deterministic steps where you need precision, AI steps where you need creativity, and loops that iterate until tests actually pass. Archon is the first open-source harness builder for AI coding - encode any workflow as a YAML file in your repo and run it from CLI, Web UI, Slack, GitHub, etc. In this video I break down what harness engineering is, why it matters, and demo Archon end-to-end including building custom workflows from scratch. ~~~~~~~~~~~~~~~~~~~~~~~~~~ - If you're interested in building your own AI second brain to save yourself hours every week, check out the Dynamous community and upcoming 4 hour second brain workshop: https://dynamous.ai/second-brain-bootcamp - Come to the Archon livestream this Saturday! https://youtube.com/live/srx9iwnjK2M - Archon GitHub repo - the first open-source harness builder for AI coding: https://github.com/coleam00/archon - Archon skill (ask your coding agent to copy it into any repo): https://github.com/coleam00/Archon/tree/main/.claude/skills/archon - Stripe Minions blog post: https://stripe.com/blog/minions-stripe-engineering ~~~~~~~~~~~~~~~~~~~~~~~~~~ 0:00 Intro to the New Archon 3:07 The Evolution of Harness Engineering 5:54 How Archon Orchestrates Coding Agents 8:48 Installation and Setup Guide 15:03 Running an Archon Workflow End-To-End 17:01 Archon Web Dashboard 18:47 How Archon Workflows Work 25:52 Running Multiple Workflows in Parallel 27:40 Building Custom Archon Workflows ~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.
