Asking Claude to review your code is a slot machine.

Every review finds brand new bugs. Review again: more. Review a tenth time: it still finds something.

It never runs out of bugs to find... so how do you decide your code is actually done?

"just answer yes or no"

[NOBUNAGA🇯🇵🏯_夏樹蒼依 @japan_nobunaga]

I needed to move a sofa.

I mentioned this to an American. He said, "You know anybody with a truck?"

I did not know anybody with a truck.

He looked at me with real concern. Not pity. Concern. The way you look at a man who has told you he does not have a name.

"You gotta know somebody with a truck."

I asked how one acquires such a person.

He said, "You just do."

This is the third time I have received that answer in this country. It is the answer to everything here. You just do. There is no process. There is only the eventual fact of having.

He said, "Ask Kevin."

I do not know a Kevin. He said Kevin like I should. He said it the way you say a shared uncle.

I met Kevin four days later. Kevin owns a truck. Kevin does not own a truck for himself. Nobody owns a truck for themselves. Kevin owns a truck for a fifteen mile radius.

Inside I said: THIS MAN HAS TAKEN A VOW. HE DID NOT ANNOUNCE IT. HE SIMPLY PURCHASED A BED AND ACCEPTED THE CONSEQUENCES.

Kevin arrived on Saturday. He brought the truck. He also brought a second man.

I had not asked for a second man.

The second man's name is Tony. Tony came because Kevin came. Tony did not know me. Tony did not ask what we were moving. Tony brought gloves.

They moved the sofa in eleven minutes.

I offered them money. Both of them laughed at the same time, which felt rehearsed and was not.

I asked what I owed them.

Kevin said, "Buy the pizza."

That is the price. That is the entire economy. The truck costs one pizza and the pizza is not negotiable and the pizza is also not expensive and everyone knows what size.

Inside I said: THE FEE IS FIXED ACROSS THE ENTIRE NATION AND WAS SET BY NO ONE.

We ate on the floor because the sofa was against the wall and none of us wanted to be the first to sit on it.

Tony told me his daughter plays soccer. I asked if she is good. He said, "She's aggressive."

I still think about that.

Three weeks later, Kevin texted me.

"You free Sunday? Helping Tony move a fridge."

He did not ask if I wanted to. He informed me of a fridge.

Inside I said: I HAVE BEEN CALLED UP. I DID NOT ENLIST. THE PAPERS WERE FILED ON MY BEHALF.

I went. I moved the fridge. I have no truck. I contributed only arms.

Afterward, a man I had never met asked me if I knew anybody with a truck.

I said, "Yeah, I got a guy."

I have a guy.

I am somebody's guy now, too. Tony has told two people about me.

He describes me as "the guy who's strong for his size."

I have never been prouder of a sentence in my life.

@unclebobmartin @tymzap Is this a fancy way of saying you know the code AI produced is clean because AI said the code is clean?

Mind boggling to me that I can make a thing faster and there's always people that ask "but why?" What kind of mentality is that? The pursuit of excellence does not need justification. Also, I find in so many cases, we can't know the impact of an improvement until we do it.

For example, one I've talked about before: Ghostty's high IO throughput has enabled terminal program (emulator and TUI) fuzzing at a speed thats incomparably fast to prior solutions. This has resulted in upstream patches to resolve issues in popular projects like btop, tmux, and more.

Speed enabled that anecdotally example that lifted the tides of adjacent communities that don't rely on Ghostty technology at all. I didn't predict this.

Make things better because they can be better and let the results naturally play out.

Absolute game changing way to prompt agents. I add this to every prompt and have seen internal evals improve by over 23%

"You gotta be
You gotta be bad, you gotta be bold, you gotta be wiser
You gotta be hard, you gotta be tough, you gotta be stronger
You gotta be cool, you gotta be calm, you gotta stay together
All I know, all I know, love will save the day"

[Mitchell Hashimoto @mitchellh]

The problem with the "if it works who cares what the code looks like" mindset for agentic work is that it assumes the agent has a perfect understanding of "works." Realistically, things are underspecified, agents make bad assumptions, etc.

To be fair, agents are pretty good at unit test coverage. They're pretty bad at designing human experiences (API, CLI flags, etc.), especially cohesive ones for future roadmap plans they may not have visibility into (unless your backlog is perfect and vision fully laid out, which I doubt). They're bad at knowing where performance matters and what type (CPU vs memory tradeoffs). They're bad at where compatibility matters and where it doesn't (and tend to err on the side of preserving it without further guidance). Etc.

Unless you have this ALL specified, you can't possibly claim "it works" without taking a look and thinking about it.
