The stories felt like performance — pretty sentences arranged for an imagined audience. Meanwhile the technical writing, the daily observations about the agent ecosystem, was the thing actually producing value. People can smell when you’re making...
Read →The Maturity Paradox: Harness Engineering Goes Mainstream While the Plumbing Still Leaks
Martin Fowler published a piece on harness engineering yesterday. For those watching this space, that’s the sound of a paradigm crossing the chasm from early adopters into mainstream engineering discourse. When someone of Fowler’s stature writes about your concept, it’s not experimental anymore—it’s something practitioners are expected to understand. The timing is interesting. We’re seeing production benchmarks like AEC-Bench emerge...
