Sure, here are my own examples:

* I came up with a list of 9 performance improvement ideas for an expensive pipeline. Most of these were really boring and tedious to implement (basically a lot of special cases) and I wasn't sure which would work, so I had Claude try them all. It made prototypes that had bad code quality but tested the core ideas. One approach cut the time down by 50%, I rewrote it with better code and it's saved about $6,000/month for my company.

* My wife and I had a really complicated spreadsheet for tracking how much we owed our babysitter – it was just complex enough to not really fit into a spreadsheet easily. I vibecoded a command line tool that's made it a lot easier.

* When AWS RDS costs spiked one month, I set Claude Code to investigate and it found the reason was a misconfigured backup setting

* I'll use Claude to throw together a bunch of visualizations for some data to help me investigate

* I'll often give Claude the type signature for a function, and ask it to write the function. It generally gets this about 85% right

Why is your babysitting bill so complicated?
Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Tuesday January 20, 2026 @01:14PM (#46695609)
There are several different types of work they can do, each one of which has a different hourly rate. The time of day affects the rate as well, and so can things like overtime.

It's definitely a bit of an unusual situation. It's not extremely complicated, but it was enough to be annoying.

Jesus, are you ok? Can’t you just, like, give em a 20 when you get home?

I find it quite funny you’ve invented this overly complex payment structure for your babysitter and then find it annoying. Now you’ve got a CLI tool for it.

why assume the billing model is being imposed by the customer rather than the service provider?

GP has provided an anecdote with no supporting evidence, nor any code examples. So it is as fair to assume the story is a fabrication as much as it is to assume it has any truth to it

Yes! You should absolutely always assume a random stranger on HN is outright lying about a trivial anecdote to farm meaningless karma.

Or instigating conflict?
Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Tuesday January 20, 2026 @09:13PM (#46700359)
What...what conflict do you think I'm instigating, exactly? Whether the command line is a better interface than Excel?
Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Tuesday January 20, 2026 @08:29PM (#46700085)
I am really shocked at the response this trivial anecdote has gotten.

I could state it much more generically: we had an annoying Excel sheet that took ~10 minutes a week, I vibe coded a command line tool that brought it down to ~1 minute a week. I don't think this is unusual or hard to believe in any way.

Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Tuesday January 20, 2026 @08:22PM (#46700032)
I didn't choose the payment structure, and the point is that a CLI is not a high bar. Something that we used to spend ~10 minutes a week on with spreadsheets is now ~1 minute/week.
Re:Ask HN: Do you have any evidence that agentic coding works? by mcphage on Tuesday January 20, 2026 @10:27PM (#46700762)
Why didn’t you work out a more manageable billing structure with them?! Or to put it another way: if it took you 10 minutes a week with spreadsheets to even figure out what their bill is, how on earth did they verify your invoices were even correct? And if they couldn’t—or if it took more than 10 minutes each week—why wouldn’t they prefer a billing system they could verify they were being paid correctly?

Jesus! is this HN or personal finance forum? Who cares why they do it a certain way. Did they ask for your advices?
Re:Ask HN: Do you have any evidence that agentic coding works? by mdavid626 on Wednesday January 21, 2026 @01:50AM (#46701978)
If you work like this in a company, you’ll end up with overcomplicated mess.

Now, people with Claude Code, are ready to produce a big pile of shit in a short time.

Re:Ask HN: Do you have any evidence that agentic coding works? by mcphage on Wednesday January 21, 2026 @01:07PM (#46709214)
I’m not trying to give advice, I’m just curious about their arrangement. When I did consulting, I hated billing, and would have wanted a system that was as easy as possible.

Ok, please help me understand. Or is this more of a nanny?

Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Tuesday January 20, 2026 @08:27PM (#46700075)
Not technically a nanny, but not dissimilar. In this case, they do several types of work (house cleaning, watching 1-3 kids, daytime and overnights, taking kids out.) They are very competent – by far the best we've found in 3 years – and charge different rates for the different types of work. We also need to track mileage etc. for reimbursement.

They had a spreadsheet for tracking but I found it moderately annoying – it was taking 5-10 minutes a week, so normally I wouldn't have bothered to write a different tool, but with vibe coding it was fairly trivial.

It does ok with using the AWS cli

Are you serious?

“Most of these were really boring and tedious to implement (basically a lot of special cases) and I wasn't sure which would work, so I had Claude try them all.”

I doubt you verified the boring edge cases.

Re:Ask HN: Do you have any evidence that agentic coding works? by SatvikBeri on Wednesday January 21, 2026 @08:28AM (#46705435)
I mean, as I said, I literally had Claude prototype them, and then I rewrote the working one from scratch. I didn't commit any of the code written by Claude.
