Senior Prom?

Short for Senior Prometheus?

That special night where you get all dressed up and get your liver eaten by an eagle?

For 3D printing? Sure.

For most other things, those verbs don’t sound quite right to me.

In general, I don’t think we need special verbs for this, but I’ll be curious to see if any arise and catch on. β€œSlop” and β€œvibe coding” really took off as terms.

Maybe β€œvibed” or β€œClauded”?

I think "made" works too.

For aesthetic works, "created" or "generated" depending on the iterations and effort.

30-second Nano Banana pic for a pun? Generated.
Website where I tweaked the CSS manually? Created or made.

Yup, I use "built" for stuff I put work into over many iterations.
e.g., "Check out this game I built in Godot!"

If it's an easy one-shot, then I use "generated."
e.g., "I generated a script to organize my photos into directories by date, but of course I backed them up first!"

It’s weird though because we now hook up tools so that producing words actually causes actions.

For example, deleting your home directory. Maybe β€˜rm -rf’ isn’t a speech act to linguists, but it’s something.

Imagine how fast it could be if you only rewrote it 10-20x more times!

Python -> Rust -> OCaml -> FORTRAN -> 8086 assembly -> PowerPC -> C++ -> Visual Basic -> C -> Perl -> Excel Macros -> Lisp -> Smalltalk

NumPy can inherit all the powers of all the languages!

And Claude will apologize and then we'll talk about how to avoid this happening in the future. ("Do you need another reminder in your CLAUDE . md file?)

Gemini and ChatGPT will sometimes insist that there is no chair while continuing to lean back in it.

06.03.2026 23:04 πŸ‘ 2 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

That's more likely to happen with Gemini or ChatGPT, which can get stuck and double-down on obviously wrong things.

With Claude, it feels more like advising, or even parenting? Sometimes I have to say, "Hey, don't lean your chair back, remember? It's dangerous and could break the chair."

06.03.2026 23:04 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

In my experience, working with Claude Code is a LOT like advising a grad student.

But my LLM experiences and my advising experiences may be different than yours.

06.03.2026 21:46 πŸ‘ 2 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

And when Claude does something silly that seems like it should be preventable, I ask it how to prevent this. Would an instruction in CLAUDE . md have fixed this? Oh wait, there is an instruction there already? Why was it ignored? What will it take to be more consistent here?

etc.

YMMV

06.03.2026 21:45 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

And then I have a discussion with first Claude before telling it to go forth and make the fixes.

Then back to second Claude and so on.

Some people automate this, but for research and research code there's less spec and more human guidance required I think.

"Hey, could you please take a look at HANDOFF_MAR6.md? I developed it with the help of a second Claude, and I think there's some good stuff in there. Review it carefully and let me know what makes sense and what doesn't make sense, because maybe second Claude made some mistakes too. Don't act yet."

06.03.2026 21:45 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

...and then have a chat with second Claude about what's real and severe or not. And then put together a plan as a handoff document.

Then go back to first Claude and say something like,

06.03.2026 21:45 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

"Hey, so, I have another Claude Code running but I'm pretty sure it's making some substantial mistakes. I'd like you to help audit everything it's doing. Please report on errors and oversights, big and small, but organize them by severity. Make a report in markdown. Once you're done we'll discuss."

I like to have a second Claude review and comment on the obvious stupid things done by the first Claude.

And I'm usually pretty verbose in my prompts, like...

Yes. As someone directly impacted by these laws, I’m absolutely going to wring my hands over whether suicide policy actually prioritizes well-studied, life-saving prevention strategies rather than feel-good β€œsolutions” that further marginalize and harm people already struggling w/suicidal ideation.

UPDATE: we now have THREE store bought cakes in our house.

(Also, cookie dough, but the cookie dough is homemade.)

Box plot showing prompt length distribution by week from November 2025 to March 2026, across all Claude sources (Code and Cowork, Desktop and Laptop), excluding messages over 500 words. Medians are consistently in the 40-75 word range most weeks. The heaviest weeks (Nov 24, Dec 01, Feb 09) show wide interquartile ranges extending up to 130-175 words with outliers reaching 400-500 words. Feb 23 has a notably low median of 21 words despite many outliers, reflecting short back-and-forth Cowork exchanges. Sample sizes range from 3 to 314 prompts per week, labeled above each box. Overall pattern: most prompts are under 100 words, but every active week has a long tail of 200-500 word messages.

My prompts tend to be long, too. I have this habit of giving Claude several paragraphs of rambling for full context.

10% of my Claude code/cowork prompts are over 200 words long. (And that's excluding all 500+ word prompts, which often contain cut-and-pasted text.)

Bar chart showing words typed to Claude (Code and Cowork) per week from November 2025 to March 2026, across two machines (Desktop and Laptop). The top chart shows
  word volume: early usage was Desktop-heavy at 20-25K words/week in late November, tapering off through December-January. A large spike of ~33K words appears in
  early February, dominated by Laptop Cowork usage. Recent weeks show 8-13K words with a mix of all four sources. Total typed: 125,217 words over 100 days, excluding
   103,524 words of pasted bulk content. The bottom chart shows prompt counts with similar patterns: ~300 prompts/week at peak, with the February Cowork spike being
  especially prompt-heavy. Total: 1,585 prompts. Colors: red (Desktop Code), orange (Desktop Cowork), blue (Laptop Code), teal (Laptop Cowork).

I've typed over 125,000 words into Claude Code and Cowork over the last 100 days.

I knew working on suicide research was going to be heavy.

But what's actually starting to get to me is reading all of these chatbot suicide laws and legislative proposals that call for measures that have been shown to exacerbate crisis.

Replicators have a list of β€œrecipes” and each one is already programmed.

In the holodeck however, you can prompt the computer to build you any 3D interactive world that you want, including all the rich characters inside it.

It’s very much going from a prompt of a few words to a usable experience.

Yup, samesies.

Also, it thinks this is one of my most negative valence posts:
"It’s so weird that Valentine’s Day is never on Friday the 13th."

And it thinks this is positive, when it's arguably a rather dark sentiment in context:
"It makes me extra glad I have tenure."

05.03.2026 04:58 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

So my experiences haven't been all bad. But the meds were way more important than the talking.

And when he asked, "Do you need to compare yourself to everyone else?"

And I said, "Yeah, it's kinda my job, that's how they decide whether or not to fire me."

...he just let it be and didn't try to argue me out of it. Didn't try to fix the things that couldn't be fixed. Which surprised me.

I did have one guy who was somewhat helpful, because I was worried (with good reason!) about not getting tenure, and he had a PhD and lots of friends in academia. So he had relevant perspective on my particular situation.

When he said, "You'll get tenure," it had some weight to it.

My experience was more that I would be open and vulnerable but receive very little guidance or support, so I'd just leave each session feeling worse than before. (Not always, but often enough.)

I guess I need my therapist to be a bit more sycophantic to be effective?

Seeing a human therapist requires waiting 6 months and maybe spending $1000 for a few visits (depending on your insurance and if your need qualifies for it).

...and then doing it again when you realize that the first therapist wasn't a good fit.
