En un coup d’œil

  • 70–80% quality is insufficient for production

    Seventy to eighty percent functionality is enough to excite leadership and grow the team, but not enough to meet the reliability threshold for production use—beyond that point, developers confront deep, opaque call stacks and prompt or tooling complexity.

  • Scaffolded, owned code over wrappers

    Dex Horthy argues against wrappers around internal abstractions and instead advocates for scaffolded, developer-owned code—comparing ideal tooling to shadcn, where generated code is fully owned and modifiable by the developer.

agent reliability threshold

70–80% quality is insufficient for production

Extrait original

It's enough to get the CEO excited and get six more people added to your team. But then you kinda realize that seventy, eighty percent isn't quite good enough, and that if you wanna get past that seventy, eighty percent quality bar, you're seven layers deep in a call stack trying to reverse engineer how does this prompt get built

Scaffolded, owned code over wrappers

Extrait original

You don't need a wrapper around an internal thing. You need something more like shadcn, which is like scaffold it out, and then I'll own it, and I'll own the code and I'm okay with that.

Agents are better with humans

Extrait original

Um, and my take, agents are better with people. Find ways to let agents collaborate with humans.

Contexte

Um, there are hard things in building agents, but you should probably do them anyways, at least for now, and you should do most of them.
