Building Agent Harnesses for AI Engineering Success

The most interesting AI engineering happening right now isn't inside a frontier lab's budget. It's people building their own agent harnesses and competing at the top level anyway. Geoffrey Huntley taught autonomous agents to write an entire programming language, and published exactly how he did it. Peter Steinberger built OpenClaw into the fastest-growing open-source project in GitHub history, then joined OpenAI. Mario Zechner built Pi on a simple premise: there are many agent harnesses, but this one is yours. None of them waited on a platform roadmap. They built the tool first, then used it to do work a much bigger team was supposed to be the only one capable of. That's the same instinct behind agent-directed engineering: stop waiting for the vendor to hand you the workflow, and build the harness that fits how your team actually works. The labs are running the manufacturers championship. The real racing is happening in the privateer class. We have always sided with the second group. #AgenticEngineering #AIEngineering
