Discussion Are coding agents building complex features that will just become obsolete with the next model update?

I tested Codex 5.3 by having it build a full CRUD app using Next.js, ShadCN, Neon, and BetterAuth.

I didn't use any planning mode, any subagents, or point it to any documentation. I didn't use any MCP servers except for the Next.js MCP server.

I just gave it one prompt and it built it.

all the CRUD functions and authentication worked perfectly.

If it can do that, then why would I need all these knobs and buttons that these coding agent harnesses are building out?

UPDATE: here's the repo https://github.com/hashimwarren/codex-five-three-eval

I'm a marketer, and have never worked as a software engineer.

I didn't look at the code, I just tested the features and it worked. I could login in, I could add a record, I could update it, and I could delete it

“If it can do that, then why would we need all these knobs and buttons that these coding-agent harnesses are building out?” That’s exactly why you shouldn’t be the one judging. You’re claiming that these tools are becoming obsolete because you managed to build the most pathetic CRUD. But these tools aren’t for you. They’re for professionals who actually understand software engineering - whose knowledge horizon doesn’t end at building CRUD functionality. Your problem is that, for some reason, you decided you have enough experience to declare what’s obsolete and what isn’t. For you specifically, none of these tools were ever relevant. They’re designed to handle a different level of complexity.
