Long-time reader of simonwillison.net here. It's a nice guide, but I think it's missing a few points. Point 1: Software architecture is still a differentiator in the agent era. It is the single measure that separates absolute bu..sh..t from gold. Point 2: LLM/Agent does not suffer from the maintenance burden; the human owner does. So you must somehow "make it *feel* the same suffering" when the codebase starts to become a sh.t pile. Point 3: Agent by default does not align with your goals - they pretend to be - so you need an alignment system to ensure it would do everything to achieve *your goal* (not its own goal).
