> a spec graph the agent actually reads

Nope. The agent doesn't actually read, and never will. That is, it may pull it into context randomly, and then purge it from context randomly. But any tool/harness/wrapper that claims that agents actually do something is selling you a bridge.

Also, the entire page somehow manages present a condensed example of the worst marketing + the worst LLM-adjacent speech in a few short paragraphs.

I don't get it, is this like an IDE for Claude Code + worktrees but proprietary and with added telemetry?

Any company incapable of training a frontier model is trying to squeeze themselves in between you and the frontier model that you are using.

I feel somewhat bad for JetBrains. Their entire world was flipped upside down. My first intro to a coding harness was through their IDE. Not even a month later and I stopped using their platform altogether. After the year is up I won’t be renewing any of my company’s subscriptions.

They have to try to push this stuff out to survive but none of it is innovative. Not sure why anyone would pay for this when it can be one-shot with a single good prompt. Sure, it looks fancy but I never cared about that.

I would like to use a harness that integerates with an IDE very easily. This will be helpful for me when coding in a language I largely don't know. I can kinda check things quickly in front of me. I know it just needs an editor and maybe a language server setup – but the cost of visual context switching is still costly heavy for us humans. Often things out of sight are also out of mind.

I was aiming for VS Code but since I have used Intellij and android studio a lot maybe I'll give it a try.

As usual when there's a harness release by a billion-dollar company, I like to ride its coat-tails with a little plug for mine (https://github.com/juggler-ai/juggler) since my marketing budget is $0. Juggler usually gets a warm response from HN people because it's a bit more hands-on than most of them.

I'd be interested to hear whether the 'spec' stuff works or not. I've been pondering adding a plugin for juggler based on the fact that we're rubbish at writing specs: so instead, when you prompt it, it'd get the model to list the assumptions that it's making about the task. Then the user can spot and correct any incorrect assumptions, rather than expecting the user to provide correct specs. (Haven't actually tried this yet, just speculating)

A year ago, it was not sure if the core companies around programming would move to more agent enabled workflow. Companies like JetBrains.

I love their products. But it's clear now that programming is now spec management and how do we control agents. I don't need JetBrains for that.

And spec management will become less technical as models get better. What does JetBrains think is the long term goal for this product? I don't think it'll make any sense in a few months.

As somebody who likes and uses JetBrains IDEs, I find this fragmentation of their AI strategy (if they have one) frustrating. They now have both Air and ThinkRail in a feature-incomplete state, while the existing AI Assistant – for me far more useful than either Air or ThinkRail – seems to be getting neglected. There are numerous harnesses already, with or without GUIs and editing capabilites; good integration with existing IDE functionality is where there are very limited offerings and where JetBrains could differentiate itself.

As a point of comparison, Zed does the agentic side panel overall better (though still not perfectly), but Zed is still by its nature more limited than e.g. PyCharm or CLion or RustRover or Rider.

I was at a large tech conference this week in Amsterdam, it was < 1km from the JetBrains office. They set up the booth 3 hours too late and there was no one actually there when I walked by (twice). I think they have given up?
