I don't do any of that. I find with GitHub copilot and Claude sonnet 4.5 if I'm clear enough about the what and where it'll sort things out pretty well, and then there's only reiteration of code styling or reuse of functionality. At that point it has enough context to keep going. The only time I might clear that whole thing is if I'm working on an entirely new feature where the context is too large and it gets stuck in summarising the history. Otherwise it's good. But this in codespaces. I find the Tasks feature much harder. Almost a write-off when trying to do something big. Twice I've had it go off on some strange tangent and build the most absurd thing. You really need to keep your eyes on it.

Yeah I found that for daily work, current models like Sonnet/Opus 4.5, Gemini 3.0 Pro (and even Flash) work really well without planning as long as I divide and conquer larger tasks into smaller ones. Just like I would do if I was programming myself.

For planning large tasks like "setup playwright tests in this project with some demo tests" I spend some time chatting with Gemini 3 or Opus 4.5 to figure out the most idiomatic easy-wins and possible pitfalls. Like: separate database for playwright tests. Separate users in playwright tests. Skipping login flow for most tests. And so on.

I suspect that devs who use a formal-plan-first approach tend to tackle larger tasks and even vibe code large features at a time.

I’ve had some luck with giving the LLM an overview of what I want the final version to do, but then asking it to perform smaller chunks. This is how I’d approach it myself — I know where I’m trying to go, and will implement smaller chunks at a time. I’ll also sometimes ask it to skip certain functionality - leaving a placeholder and saying we’ll get back to it later.

Same. I find that if I can piecemeal explain the desired functionality and work as I would pairing with another engineer that it’s totally possible to go from “make me a simple wheel with spokes” to “okay now let’s add a better frame and brakes” with relatively little planning, other than what I’d already do when researching the codebase to implement a new feature

It's quite interesting because it makes me wonder how we make it efficient and predictable. The human language is just too verbose. There must be some DSL, some more refined way to get to the output we need. I don't know whether it means you actually just need to provide examples or something else. But you know code is very binary, do this do that. LLMs are really just too verbose even in this format right now. That higher layer really needs a language. I mean I get it. It's understanding human language and converting it to code. Very clever. But I think we can do better.
