Andrew Ng: don't let coding agents run for hours — five skills for agentic coding
DeepLearningAI · x · 2026-09-06
In his latest letter, Andrew Ng warns that letting coding agents run autonomously for hours is costly and often ineffective. Top practitioners rely on skilled human judgment, highly iterative planning, and frequent output verification. Time should shift to architecture and writing specs, not line-by-line coding; developers must learn to direct agent workflows, calibrate autonomy, and build robust testing regimes. The letter lays out five foundational skills for agentic coding.
