Multi-Agent Collaboration: Value From Structure, Not Concurrency

Conclusion first: the value of multi-agent doesn’t come from more models; it comes from the right structure. Multi-agent without structure is just more expensive concurrency — burn 2 to 3 times the tokens to watch a group of models nod at each other. Multi-agent with structure is an execution system that can delegate, parallelize, and verify.

Diagnosis first. A single agent executing complex tasks has five structural defects — blame the execution structure, not the model’s intelligence:

Give AI a Rulebook: From Wishing Upon It to Making It Behave

Let me start with something that actually happened.

In early 2025, I added a feature to an internal system: export to Excel. Small requirement — I didn’t even write it up, just typed “add an export button to the list page” into the chat box.

The AI delivered in ten minutes. Frontend changes, new endpoint, SQL — all in one pass. I was pleased when I opened the PR, right up until review revealed: the export columns didn’t match the list page, a hundred thousand rows would hang the service outright, there was no permission check, and the tests only covered the happy path.

Rethinking Team Division of Labor

The conclusion first, so you don’t waste your read

We used to split teams by craft: frontend, backend, product design. Now we split teams by stage: Prototyper — grabs the first idea and fails fast Builder — turns the prototype into a product you can take to market Maintainer — holds the fort once the software reaches scale Scaler — takes a proven product and scales it 10x, 100x Finisher — polishes the product and the code, sands off the burrs As for why we’re only splitting this way now — the answer involves AI.

Thoughts on Dynamic Intervention in AI Agent Runtimes

Thoughts on Dynamic Intervention in AI Agent Runtimes

A few weeks ago, late at night, I stared at the agent logs scrolling through my terminal, frustrated enough to want to smash the keyboard. It was dutifully generating a requirements analysis report — it had been running for a dozen-plus minutes, pulling loads of data and drawing charts, clearly on the verge of wrapping up — when I suddenly realized the requirements were missing a key dimension: “Don’t split by region, split by user age group.” If I interrupted it now, all the context, intermediate results, and tool call state would be thrown away and it would start over. If I didn’t, it would soon produce a wrong report that would cost me just as long to fix by hand.

AI Agent Skills and MCP: Which Ones Are Worth Installing

Conclusion first: plenty of tools out there can be installed, but most of them sit there gathering dust after installation. Below is what I filtered out of the things I actually use, sorted into five scenario categories, with a few genuinely used picks in each.

If you want a single install that covers most scenarios, take a look at this one:
