We just published a couple of the projects I've been working on this spring. https://primeradiant.com/blog/2026/greenfield-and-iterative-development.html
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.

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.

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'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 designed it to focus on reading and navigating between docs, but it has a bit of light editing support as well. It's the perfect app to read all those markdown files your agent makes.

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.

I am *so* amused that my AI groupchats are all frantically trying to get their hands on copies of @cstross@wandering.shop's Accelerando...because clawdbot/moltbot/openclaw have been cosplaying fast-takeoff sentient AI lobsters.
