Description

Ever wondered what the best AI coding tool in the world (Claude Code) could create if you gave it a full 24 hours and tools to validate its own work? Well that's exactly what I do in this video, and I was VERY impressed with the results to say the least. Coding agents usually don't work for 24 hours straight - at some point they just decide they're done and return control back to you. But with this "harness" Anthropic has created (and open sourced!) for long running agents, we can give it a super complex task and have it rip through all the features over hours and hours. Practical? Maybe not yet - it's very experimental. But boy is this fascinating to get a glimpse into the future of agentic coding. ~~~~~~~~~~~~~~~~~~~~~~~~~~ - The Dynamous Agentic Coding Course is now FULLY released - learn how to build reliable and repeatable systems for AI coding: https://dynamous.ai/agentic-coding-course - Anthropic's Article on Harnesses for Long Running Agents: https://www.anthropic.com/engineering/effective-harnesses-for-long-running-agents - GitHub Repo for the Harness I Use in the Video: https://github.com/anthropics/claude-quickstarts/tree/main/autonomous-coding ~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 - Introducing Anthropic's Harness for Long Running Agents 01:19 - What I Have in Store for You Today 02:47 - How the Heck does the Harness Work? 08:42 - Setting Up the Coding Agent Harness 10:34 - Kicking Off the 24 Hour Agent Execution! 12:26 - Diving into the Initializer Agent Prompt 13:46 - Understanding the Coding Agent Prompt 17:14 - Security & Flexibility Built into the Harness 19:58 - First Coding Agent Started! 22:18 - Final Results after 24 Hours of Coding NONSTOP 25:29 - This Harness is Legit ~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.
