HumanLayer CEO Dexter Horthy, who coined "context engineering", on why AI agents degrade codebases over time. He breaks down a benchmark that measures AI code quality across features, and how his team ships with agents without drowning in slop.In this video, we cover:SlopCodeBench, SWE-bench and which coding benchmarks to trustToken maxing, dark factories and the "Instagram phase" of AI engineeringWhy 2-4x productivity beats chasing 100xPull requests, design docs and how engineers build taste nowDex's agentic engineering workflow: one-shots, overnight janitor bots and research-design-planFor engineers and engineering leaders adopting AI coding agents who want to know what's real and what works in teams at scale.Timestamps:00:00:00 - The Man Who Coined the Term: Context Engineering00:00:54 - SlopCodeBench: Proof AI Makes Codebases Worse Over Time00:05:49 - Background Agents and the Enterprise Friction Problem00:08:13 - Why You'll Never One-Shot a Big Feature00:11:18 - Scaling Agentic Engineering to 1,000 Engineers00:16:19 - Dark Factories, Fake Hype and Token Maxing00:19:55 - Why 2-4x Faster Beats Chasing 100x00:21:31 - Should Teams Stop Doing Pull Requests?00:24:20 - Can Deterministic Tools Replace Code Review?00:27:37 - How to Build Engineering Taste When AI Writes Code00:33:05 - Dex's Agentic Workflow: One-Shots and Janitor Bots00:35:18 - Research, Design, Plan: Shipping Big Features With Agents00:38:35 - Why Overnight Agents and Heavy Parallelism Backfire00:40:10 - Subscription Maxing vs Paying Per Token00:42:40 - Parallelize Like Poker, Not a Slot MachineDex Horthy: https://x.com/dexhorthyDex's talks and deep dives: https://aithatworks.bold.video#AgenticEngineering #AICoding #SoftwareEngineering
