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.
