Prompt Engineering Was the Beginning, Not the Skill
It got named as a discipline when the prompt was the entire interface. It's now one input among several — and if better prompts have stopped helping, five specific things are usually why.
-
The Loop Decisions You Only Make Once
Most agent design choices are cheap to revise. Six aren't — and in every case the answer that ages well is the same one, for the same reason.
-
Context Engineering Is the Job Now
Not prompt writing — that's the visible part and the small one. The work is deciding what reaches the model, in what form, at what moment, and it's where most agent failures start.

Lock-In Risk in Agent Tooling, and How to Keep Optionality
The API call is trivially portable — the coupling forms in four other places, and the worst one isn't technical at all. One question tells you how exposed you are.

The Moat Isn't the Model — It's the Loop Around It
"The model isn't the moat" is now widely said and stops one step short. What compounds shares a property — it accumulates from watching real usage, which is why it's invisible from outside.
-
Will Open-Source Harnesses Eat Commercial Coding Tools?
The premise is right — the loop is a few hundred lines. The conclusion is too fast, because the loop isn't the product, and one of the real advantages is invisible from outside.
-
What a Harness Actually Is, and Why It's the Real Product
A model takes messages and returns tool calls. Everything else is the harness — and it explains almost all the variance between agent systems that share the same model.
-
IDE Assistants vs Agent Harnesses: Different Products, Different Futures
They get discussed as one category and have opposite requirements on latency, context, failure cost, and model tier. One is commoditizing into a feature; the other's differentiators aren't AI capabilities at all.

If Intelligence Gets Cheap, What Becomes Scarce?
More useful than asking what gets cheap. Everything on the scarce list has one of two properties — and neither can be produced on demand, which is exactly why they stay scarce.

What Falling Inference Costs Change About Agent Design
Relaxed cost pressure mainly buys back the verification steps you declined. It doesn't rehabilitate filling the context or adding turns — those were quality problems wearing a cost disguise.
