Key lessons include: writing clear specifications before requesting code, treating AI context as a finite resource by keeping tasks small and focused, always reviewing AI-generated plans before implementation, avoiding having the same AI review its own output, and maintaining strict diff size discipline. The author advocates for spec-driven development as the core workflow shift, arguing that the habits AI rewards — clear requirements, small changes, independent review, meaningful tests — are simply good engineering practices that outlast any specific tool. ## Full article daily.dev links to this article rather than hosting it.

I like the idea of keeping diff size down. Lots of good tips in here to strengthen my workflow and to ensure the end result is my responsibility and fully owned and understood. Thanks Mohamed. **@kartiknvj** · 1 upvotes > The lesson that lands hardest for me is never letting the same model review its own output, because a model scoring its own work carries a self-preference bias and will wave through the thing it just wrote. Spec-driven development framed as good engineering that outlasts the tool is the right way to hold it, since small diffs and clear requirements were correct long before agents. Treating context as a finite budget is underrated too, most of the wrong outputs I get trace back to a task that was too big for one pass. **@erikandersoon** · 0 upvotes > The author's framing that AI rewards good engineering is the most optimistic take on this shift. It's tempting to think AI makes sloppy work faster, but the reality is that AI amplifies whatever habits you already have. If you have weak specs, AI gives you weak code faster. If you skip testing, AI gives you untested code faster. But if you practice spec-driven development, small changes, and independent review, AI becomes a force multiplier for good engineering. The habits that AI rewards are the habits that make you a better engineer regardless of the tool. ## Similar posts on daily.dev - [On AI](https://daily.dev/posts/on-ai-y4nttoreo) · openmymind · 0 upvotes · 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#code-review](https://daily.dev/tags/code-review), [#ai-assisted-development](https://daily.dev/tags/ai-assisted-development), [#spec-driven-development](https://daily.dev/tags/spec-driven-development) [View this post on daily.dev](https://daily.dev/posts/what-ai-secretly-changed-about-my-engineering-71x5m4e3y)
