Jetbrainz needs to give up on Junie and their in house ai and focus on integrating with the established tools. If they don’t, VS code will consume them.

They've already done that. After the Junie fiasco, they pivoted to "AI Assistant", where Junie is just another provider alongside Anthropic and OpenAI. In theory, you have Claude Code inside Jetbrains IDEs now.

What's incredible is just how bad it works. I nearly always work with projects that mount multiple folders, and the IDE's MCP doesn't support that. So it doesn't understand what folders are open and can't interact with them. Junie the same issue, and the AI Assistant appears to have inherited it. The issue has been open for ages and ignored by Jetbrains.

I also tried out their full line completion, and it's incomprehensibly bad, at least for Go, even with "cloud" completion enabled. I'm back to using Augment, which is Claude-based autocompletion.

Yeah, it's quite odd that they can't get AI tools to work, especially considering so many OSS tools available that work surprisingly well (cline, opencode, etc.).

How do these compare? I'm very familiar with Augment and particularly enjoy its fast completions. I mostly don't use its agent, but rather Claude Code in the terminal, because the agent seems superior.

But Augment is not the most stable. I've had lots of serious problems with it. The newest problem that's pushing me over the edge is that it's recently have been causing the IDE to shoot up to use all cores (it's rare to see an app use 1,000% CPU in the macOS Activity Monitor, but it did it!) when it needs to recompute indexes, which is the only thing that has ever made my M2 Mac run its fan. It's not very reliable generally (e.g. autocompletions don't always appear), so I'd be interested in trying alternatives.

They already kinda did. They brough ACP support which allows you to somewhat integrate Claude Code, Gemini CLI or OpenCode they also recently brought BYOK support so you can use an existing provider and don't pay extra subscription for it.

ACP seems super under the radar. It has some support, but it got merged into A2A, which I don't hear anyone talking about, so it seems like it's going to die on the vine.

This is really too bad, as editors should be able to plug and play with AI tooling in the same way that editors <> LSP can plug and play with language tooling.

I mean I tried Zeds implementation with OpenCode was working fine but yeah the whole standards part is really complicated right now. I can't keep track of it. I hear about A2A but did not know it was merged with ACP.

My beef with zeds implementation is they haven’t kept it up to date. I really like the ide integration but when you don’t support half the things that make Claude code really nice, like hooks, it kinda defeats the purpose

I'm not sure this is true, do you have a source? Maybe conflating this with the recent Agentic AI Foundation & MCP news?

I think you may be confusing Agent Client Protocol with Agent Communication Protocol.

I think that https://agentclientprotocol.com/ was mentioned as ACP

I really enjoy Junie, I find it working better out of the box than Claude code. I do wish they integrated their amazing refactoring tools into it though.

Is there something with the Claude code plugin for JB IDEs you don’t like? Is there something the VSCode Claude Code plugin does better?

I can’t speak for Claude, but Gemini is laughably bad. Like, does someone who develop this shit ever tried to use it? Is it all crab hands that only use mouse? It’s a single line change to switch focus to THE ONLY INPUT on a tool window, but no, you have to use a shortcut to switch to Gemini window and then MOVE YOUR MOUSE across the screen to select input or press tab like 5 times. Embarrassment.

VSCode? Select AI view via shortcut or CMD + P and you’re done. That’s how you do it.

If not VSCode then Zed. It feels like Zed is what they wanted Fleet to be.
