Product at @AiwynAI, tinkering with stuff

[Derek DeHart @derekdehart]

I built an app called cordelle to help people get no-bullshit guidance on what's just now possible with the most common AI tools out of the box.

I hope this inspires more questions than it answers, and I hope you'll share those questions with me.

feeling myself molting recently. painful, unsettling, but… good. overall, good. wouldn’t trade this feeling.

[Derek DeHart @derekdehart]

@clairevo @chatprd @cursor_ai @claudeai @midjourney Was Opus involved in any of the design decisions, or just implementation?

[Derek DeHart @derekdehart]

@adocomplete Is this still rolling out? It's not available as of the latest update on my Windows machine

[Derek DeHart @derekdehart]

More than ever, we have a responsibility to be intentional with relationships with technology. I also think we have a responsibility to be intentional with how we represent technology to those in our lives who may not be quite so plugged in. https://t.co/IBsZg92Uk5

If they'd been written five years ago, most of my recent journal entries would have been science fiction.

Wild.

[Derek DeHart @derekdehart]

I don't really consider myself a journaler. Journaling is something that's had a lot of false starts for me over the years.

Since December, though, I've been writing down something by hand every day. Sometimes it's a sentence. Sometimes it's a few pages.

[Derek DeHart @derekdehart]

I write a lot about AI because it's on my mind so much, because it's something that has, for better or worse, permeated both my professional and personal life. And as I jotted down a few sentences tonight, I realized:

[Derek DeHart @derekdehart]

@bcherny I have a lot of trouble sharing plugins installed via marketplace between projects. They seem to be cached somewhere and can only be installed by manually updating Claude Code's settings. Is there more documentation somewhere for setting this up effectively?

[Derek DeHart @derekdehart]

I guess its time has come

[Logan Kilpatrick @OfficialLoganK]

officially giving up my “PM” title, we are all members of the technical staff now, time to embrace it

[Derek DeHart @derekdehart]

@adocomplete It's a shame prompt-based subagent stop hooks don't seem to work. Seems like a very powerful pattern if it were functional

[Derek DeHart @derekdehart]

@CEOAlexColon @trq212 Same for me, MCP tools taking up 51.6K tokens, 25.8% of context after a fresh update and restart. Is there something else I need to do to take advantage of tool search?

[Aaron Slodov @aphysicist]

millennial gamers are the best prepared generation for agentic work, they've been training for 25 years

[Derek DeHart @derekdehart]

Hey @bcherny what's the fastest way to disable or enable an MCP server on the fly now that you've removed @-mention for MCPs? Or is the idea that enabling MCPSearch will preclude the need to toggle by managing MCP details in context better?

[Derek DeHart @derekdehart]

Claude Code crashed on me for the first time today. I feel like I oughtta get a badge for that or something

[Derek DeHart @derekdehart]

"The line between writing and building is dissolving."

Fascinating way to think about this moment that I hadn't considered. This is a great read.

And congrats to @yourgirlhils for taking this career leap!

[hilary gridley @yourgirlhils]

I quit my job because I think writing just became more powerful than it's been in decades.

(I know, I know. Everyone's saying AI is going to kill writing. Hear me out.)

I've spent the past few years building AI products and tools at WHOOP and outside of work. The experience has changed how I think about writing entirely.

I wrote an essay about how to identify your superpower. Then I thought: what if people could *interact* with this instead of just reading it? So I turned it into a Custom GPT that walks you through the exercise and outputs a fully unique and personalized superpower at the end.

The essay became an experience.

I've done this a bunch of times now. I write something, then realize I can make it *do* something. No code required, just clear articulation of what I want to happen. Words have become a building material. Literally! I think this is fascinating, and extremely exciting.

So I'm going full-time on exploring this. I'm relaunching my newsletter as "Writerbuilder" to dig into what it means when writing and building collapse into the same activity. Expect tools, workflows, things I'm learning, and a lot of experimentation. Subscribe to follow along!

(Also, I'm four months into motherhood and figuring out what I want this chapter to look like. Unsurprisingly, that's a big factor in my thinking on how I want to shape this "writerbuilder" career. So expect that to swirl in too.)

PSA: @claudeai is just as bad as humans about remembering that it needs to write dates with 2026 instead of 2025

[Derek DeHart @derekdehart]

@trq212 Man, I created a skill to support this workflow and it's amazing

[Ado @adocomplete]

Happy New Year!

In December, I shared 31 days of Claude Code features. Thanks for following along and the replies, the questions, the "wait it can do that?"

If you missed any (or want them all in one place), here it is.

Your 2026 terminal is about to be very different. 🧵
