AI coding has made me dramatically faster. But I’m starting to think we’re creating a completely new category of problems

Hi everyone,

I’ve been building more and more of my products with Claude Code, Codex and other AI coding tools. The speed is ridiculous.

Something that might have taken me a week before can sometimes be built in a day. But the longer a project survives, the more I notice the problems changing. The hard part isn’t always writing the code anymore.

Things that bug me a lot are like:
 - Starting a fresh AI session and having to explain the product again.
 - The agent understanding the codebase but not why something was built a certain way.
 - Requirements slowly changing without you realizing it.
 - One agent undoing or contradicting decisions made in another session.
 - Forgetting whether something is actually finished, half-built, abandoned, or just discussed.
 - Coming back to something you built weeks ago and thinking: **why the hell did I do it this way?**

AI confidently changing something that technically makes sense but is completely wrong for the product. Context windows filling up right when the agent finally understands what you’re building. Having decisions scattered between chats, prompts, commits, notes, and your own memory.

And I’m curious whether this is just how I build, or whether other people building heavily with AI are running into the same thing.

So I want to ask the vibe coders / AI builders here: What are the problems you repeatedly face when building real products with AI?

I’m especially interested in the annoying problems that start appearing after you’ve been working on the same product for weeks or months. The stuff that makes you think: “There has to be a better way to do this.”

Could be context loss, debugging, security, testing, requirements, managing multiple agents, remembering decisions, deployment, maintaining old AI-generated code — anything.

I’m currently collecting these problems because I’m building something, but I don’t want to build based on assumptions about what vibe coders need. I’d rather hear it directly from people actually doing this every day.

What’s your #1 frustration with building software using AI coding agents right now?
