A new analysis argues that as AI coding tools make implementation cheap, software architecture becomes more important and visible, with verification replacing code generation as the bottleneck. Dex Ho…
Dex Horthy, founder of HumanLayer, has outlined a four-gate software development workflow—Product, Architecture, Program Design, and Vertical Slices—designed to make critical decisions before code is …
Claude Opus 5 passed 24% of 17 checkpoints on a subset of SlopCodeBench, quadrupling the 6% pass rates of Opus 4.8 and Sonnet 5, but achieved this by producing roughly 29,000 source lines versus about…
Dex Horthy, CEO and cofounder of HumanLayer, coined the term 'context engineering' and shared lessons from building AI agents, including that shipping unread code leads to disaster within months after…
Engineers are shifting focus from model selection to harness engineering—the design of prompts, tools, and scaffolding around AI models—after observing that a decent model with a great harness outperf…
The AI Engineer World's Fair concluded with a debate on the viability of autonomous software factories, pitting advocates like Geoffrey Huntley and Ian Livingstone against skeptics Dex Horthy and Greg…
Context engineering has emerged as a critical discipline in AI development, moving beyond prompt engineering to manage an AI's working memory. Developers are grappling with the challenge that models l…
Here is a 2-3 sentence factual summary of the article: The article explains that while many engineers can identify AI coding agent hallucinations—such as the model inventing nonexistent APIs or ignor…
