I find it so weird that people are so bullish on the CLI form factor when they are literally just adding functionality that IDE based agents get for free. Stuff like improved diff tools and LSP support in the terminal instead of idk... just using a GUI/IDE? Pretty sure Cursor has had this for a while.

What IDE agent gets access to LSP? I use Zed and unless there is some MCP server that provides the same thing as the LSP server, the Zed agent won't have access, even though it's in an IDE that supposedly has this information

cursor

I was hoping LSP support would be implemented. I know there are existing MCP servers that can do something kind of similar, but I doubt the agent would be smart enough to consistently utilize the LSP MCP. Here's hoping for less greps.

I mean, OpenCode has had this feature for a while: https://opencode.ai/docs/lsp/

OpenCode is so underrated.

One of my favorite features is that you can run it as a server, and then it has a API and SDKs to manage sessions etc.

Great to build a centrally managed agent for your team.

I am super bullish on claude code / codex cli + LSP and other deterministic codemod and code intelligence tools. I was playing around with codex this weekend and honestly having a great time (my opinion of it has 180'd since gpt-5.2(-codex) came out) but I was getting annoyed at it because it kept missing references when I asked it to rename or move symbols. So I built a skill that teaches it to use rope for mechanic…

Interesting to see that you work at OpenAI but had to build a skill like this yourself.

Surprised that you don't have internal tools or skills that could do this already!

Shows how much more work there is still to be done in this space.

No Python LSPs yet!

There's pyright-lsp. Isn't this a Python LSP ? or is it lacking important features ?

Can you do @ and refer to a method or variable in a file with lsp support? Otherwise, how can lsp context be used in Terminal chat?

A big use case will be to tell the LLM what the type of an expression is.

Amazing how long this took. Serena has been doing a not bad job of helping solve this issue. But this has been an obvious built in for agents for some time now. https://github.com/oraios/serena

I really can't understand why JetBrains hasn't integrated its refactoring tools into the AI system. Really missed the boat on making their platform transformational for AI coding. Imagine how much smaller the context would be for a tool that renames a function than editing hundreds of files. This LSP support is a good start but without the mutation functions it is still pretty lackluster. Plus LSPs aren't as good as…

I think they are completely screwing up the AI integration.

After years of JetBrains PyCharm pro I'm seriously considering switch to cursor. Before supermaven being acquired, pycharm+supermaven was feeling like having superpowers ... i really wish they will manage to somehow catch up, otherwise the path is written: crisis, being acquired by some big corp, enshitification.

It's strangely difficult to find official information about this, but here's what I've learned: • Use `/plugin` to open Claude Code's plug-in manager • In the Discover tab, enter `lsp` in the search box • Use `spacebar` to enable the ones you want, then `i` to install Hope that helps!

Yeah, I posted here because I was completely blindsided when my claude asked if I wanted to install a go lsp. I didnt even know that was a thing. A little googling led to this changelog from 3 days ago, but I was surprised I hadnt seen any previous mentions of this online (from either creators, anthropic, or HN posts). I am disabling it for now since my flow is fine at the moment, I'll let others validate the usefuln…

I got an unexpected offer to install the LSP plugin for swift-lsp at 6:30pm pst on 12/19pm and again yesterday afternoon the text reads:

LSP Plugin Recommendation

LSP provides code intelligence like go-to-definition and error checking

Plugin: swift-lsp

Swift language server (SourceKit-LSP) for code intelligence Triggered by: •swift files

Would you like to install this LSP plugin? › 1. Yes, install swift-lsp 2. No, not now 3. Never for swift-lsp 4. Disable all LSP recommendations
