migrating all my personal apps and agents on cloudflare to a single monorepo has been a clutch move

Cost of code dropped but the bar for products is higher than ever.

There's a version of shipping fast that comes from understanding the problem and a version that's just because it's easy now.

literally anyone can ship quickly if they sacrifice reliability. it’s not in any way impressive.

@jeremyphoward seriously, what makes llms write like this all the time? "it's not x, it's y" "the real x is, y"

What's the opposite of slop-forking, where you use AI assistance to carefully build a well-tested, high-quality library you're deeply invested in bringing into existence? Kino-forking?

@mitsuhiko so good, thanks for sharing! I think we are all really excited by the possibilities agents have unlocked and leaned too hard into speed, but with time we'll rebalance this with fundamentals

Software has been composable for decades. You don't build everything from scratch. You plug into what's already there. Libraries, APIs, contracts. Products weren't like that. You logged into an app, used what they gave you, and that was it. Some offered a public API but most didn't. That's not really acceptable anymore. If a product doesn't have a public API it feels incomplete. Even better if it has an MCP, a CLI, an SDK, webhooks, anything that lets you extend it beyond what the product itself supports. What changed is that more people can now orchestrate software without deep technical expertise. Agents need something to plug into. Products had to follow.

tbc - i don’t think agentic programming is going away, and i still heavily use it and will continue to, but i’m finding more and more i just need to drop into code and write it myself and it’d be nice to have this for nvim or really i want to start work by writing code myself and then let an agent run with it

i think i’m back to wanting a really good tab model - any progress here outside of cursor (i don’t have access to supermaven) and for nvim?

@RhysSullivan yes expectation now is for products to be composable (like software has been)

my new criteria when evaluating products is if they have a public api that i can give to my agent churning off of my budgeting app because they don't

I’ve spent years making beats on hardware, but I wanted a sampler that was as fast as opening a browser tab. So I built Mezcla 🎛️ Minimalist, web-based, and built for the producer's workflow. No DAW bloat, just chops. Try it here: mezcla.capelo.me

@GergelyOrosz yes, I think most pivoted too hard in one direction (due to excitement?) and need to find balance now

When it comes to AI agents / AI tooling + coding, I hear an awful lot of talk about: Efficiency Iteration speed / PR output rate / lines of codes produced I hear zero mentions about: Quality Customer obsession This will bite back, and it probably already is...

Unpopular opinion: ALWAYS read the code, whether written by an AI agent or sentient meatbag Too long to read? Scope it down & redo Can't understand it? Use AI to explain (it's good at that) Too lazy? Go into upper management

mfs will do anything but read the code
