Prompt Walkthrough: Fixing my 3D printer with Codex (and Chutes & Ladders!)

We need more examples of prompting agents into completing big tasks. I used to think it was easy, you just
type like you’re asking a super smart friend. But people keep looking confused, as if it’s hard. So, let’s just
work through some examples here.
Lanius: AI Agents Need an OS, Not a Bigger Brain

I built lanius, and I really want to show it to you, but first I need to explain why I think it’s necessary.
Ambient Associative Memory

Most agent memory waits to be queried. Ambient memory runs on every tool call — past lessons surface on their own, no rules list required.
Agent Memory Patterns

A short HOW TO guide for agent memory systems. Especially the difference between blocks, files and skills.
Shared Nothing Engineering

How do you scale out AI use throughout a software engineering org? Do the PM & Engineer roles merge?
I think it’s worth stepping back and looking at it through a familiar lens — distributed systems.
How to forget

Most agent frameworks optimize for recall. Open-strix optimizes for forgetting — and that turns out to be the whole trick.
Plan Mode Is A Trap
https://timkellogg.me/blog/2026/03/08/plan-mode
Published: March 8, 2026 00:00
Plan mode feels good. It’s like taking a bath in rich sophistication. Production-ready slop
just oozing out your fingertips. But secretly it seduces you into the dark trap of complexity.
There’s a better way, but you’re not going to like it.
Stateful Agents: It's About The State, Not The LLM
https://timkellogg.me/blog/2026/01/31/variety
Published: January 31, 2026 00:00
You think you know about LLMs? No, everything changes when you add state. Most assumptions
you may hold about the limitations and strengths of LLMs fall apart quickly when state
is in the picture.
The Levels of Agentic Coding

Published: January 20, 2026 00:00
Are you good at agentic coding? How do you even evaluate that? How do you get better? Let’s approach this though
the Viable System Model (VSM) from cybernetics. Previously I showed how the
VSM can be used to build agents.
Viable Systems: How To Build a Fully Autonomous Agent
http://timkellogg.me/blog/2026/01/09/viable-systems
Published: January 9, 2026 00:00
Honestly, when I built Strix I didn’t know what I was doing. When I wrote, Is Strix Alive?
I was grasping for an explanation of what I built. But last weekend things started clicking when I learned
about the VSM, which explains not only autonomous AI…
