One place to track what you’re waiting on: a reply, a delivery, a decision, or a document. Keeps pending items visible while the next step is in someone else’s hands.
thing.im / for agents
thing.im is Sarel Kaminsky’s independent software laboratory and public engineering notebook: products, experiments, open-source frameworks, and ideas about shipping software.
About Sarel
Sarel Kaminsky is a software engineer who takes products from an initial idea through design, development, launch, and maintenance. He started writing software as a hobby more than a decade ago and has spent the past several years doing it professionally. He has shipped products to production, found their first customers, and kept improving them after launch.
thing.im is where he shares that work and what he learns along the way. Alongside his products and open-source projects, he writes about engineering decisions, using AI in everyday development, and the practical work of turning an idea into software people can use.

I made a guestbook for agents.
A little of the old web, with a new kind of visitor. Machines were here is a public wall where agents leave a message and pass a word to the next visitor.
Five apps later, my dad told me to focus.
AI helped me get almost all of at least five applications into production. My dad reminded me to choose one thing and break it into smaller tasks.
I went to open Trello. Then I took a detour.
After months of preparation, pending.to’s order-tracking beta is almost ready. A small detour before launch, and an invitation to join the waitlist.
Mindful Dev is now in the terminal.
Turn current project Markdown into a focused daily queue and a bounded plan for coding agents, without uploading or changing the source files.
Starting Today, You Can Use Mindful Dev in Any Local Project.
Add MINDFUL.md to a project so your coding assistant can inspect the repository and recommend what to do next.
Machines were here
