I often have 10+ running in parallel. I’m attacking parallel problems that aren’t interdependent. Sometimes adding additional products can bring me up to 15+.

Gotta have really good test harnesses so they can largely fix themselves.

But how do you cover such amount of multi tasking? Could you give an example? I mean what kind of tasks allow such a parallelization?

context switching across the entirety of the feature surface for an app

You could easily have agents to work on login page, messaging feature, database/data model update, recommender system, backend api, etc

We have our doubts about this. Can you share your code or product? Anecdotally, my mistakes and lack of understanding exponentiate the more I try to parallelize.

Who is “we”?

As I said in the neighboring comment, for vibe coding side projects and prototypes for work I just merge and iterate. It works out more than it doesn’t. For anything bigger at work I cannot share as I’m at Apple.

But you have to keep it in your head, and remember all stuff at the same time. How is it possible to track, and do reviews one after another? Or are these pretty long running agents?

I’m not sure what you mean by keep it in your head? I know all of the parts the agents are working on. It’ll often be a mix between bigger tasks (some large refactor, new feature, etc) and small tasks (little bug fixes).

For prototyping I just merge. I don’t bother to review the code. For anything more important than I am reviewing the code and going back and forth. Basically there’s a queue of stuff demanding my attention, and I just serially go through them.

What’s also been really helpful to me is /simplify and similar code review skills (I have my own). That alone takes an agent a while to parse through everything it’s done and self reviews. It catches quite a lot itself this way.

>I’m not sure what you mean by keep it in your head?

If the project I work on is large enough, it takes me some time to get everything I need to understand for review into the short term memory. If it's small enough, it's less of a problem for me.

Honestly, I dont know. I could be mistaken about the exact number of agents - but not wrong about fact of AI-driven workflows which is heavily automated, and goes on for hours.

He's one (small) step from distinguished engineer, with 20+ patents to his name, and is an embedded programmer (largely C/C++) with 30+ years of experience in the field; and I've known him for nearly as long, so I put a lot of credence to his words.

But we don't usually talk work; he's the guitarist in our band :) [I'm the bass] So we mainly chill over music + beer. And lately, it's been less chill ¯\_(ツ)_/¯
