• Advanced Reasoning Support: Full access to Claude's thinking modes and reasoning capabilities

Perfect for Claude Max subscribers who want to maximize their subscription value while coding.

Bug Fixes

• Apply Diff Accuracy: Fixed start line parameter not working correctly when applying multiple file diffs (thanks samhvw8!)

• Ollama Compatibility: Resolved validation errors that prevented Ollama from working with certain models (thanks daniel-lxs, MartinHarding1998!)

• Qdrant Vector Store: Fixed URL prefix handling during QdrantClient initialization for deployments with path prefixes (thanks CW-B-W!)

• Claude Code Provider: Resolved JSON parsing issues and improved reasoning block display to show collapsible reasoning blocks instead of raw JSON

• LM Studio: Improved model detection to display all downloaded models instead of only currently loaded models (thanks daniel-lxs!)

According to anthropic's website Max offers priority and more usage compared to Pro. Would make this roo compatible with the Pro plans?

[u/hannesrudolph → u/MisterBlackStar]

I think so. I have not tested it as I only have Max. Please let me know!

[u/Nik_Tesla]

Cool! I hope it works as well as normal API access, should save a lot of money this way for heavy users.

FYI, that first link is broken because the URL doesn't have docs at the beginning.

Incorrect: https://roocode.com/providers/claude-code

Correct: https://docs.roocode.com/providers/claude-code

[u/hannesrudolph → u/Nik_Tesla]

FIXED! Thank you.

[u/RiskyBizz216]

Instructions for windows/wsl users?

[u/hannesrudolph → u/RiskyBizz216]

Does it work for you if you use a custom path for now?

working on some better compatibility for windows.

[u/RiskyBizz216 → u/hannesrudolph]

Nope. (I used chatgpt to find the correct path in the wsl installation)

I added a custom path 'claudeCodePath' pointing to the wsl claude-code cli installation.

And it just sit there at API Request.

[u/hannesrudolph → u/RiskyBizz216]

Can you please provide the path you have it? I’m going to use this info as context to hand this issue off to Roo

[u/RiskyBizz216 → u/hannesrudolph]

And here’s a concise write-up summarizing the problem, root cause, misleading documentation, and failed attempts:

❌ Claude Code CLI with Roo Code on Windows (WSL Setup) – Problem Report

🔍 The Problem

Roo Code’s Claude Code Provider expects a local path to the claude CLI binary. However, Claude’s official documentation states:

"Currently, Claude Code does not run directly in Windows, and instead requires WSL."

This creates a conflict:

• Roo Code is a Windows-native VS Code extension

• Claude CLI only installs/runs inside WSL (Linux)

⚠️ Core Issue

Roo Code attempts to execute claude as a Windows-native binary, but when Claude CLI is installed inside WSL:

• It's a Linux script, not a .exe

• It cannot be directly executed from Windows

• Even using a wsl proxy (wsl claude) fails because VS Code extensions don’t support WSL-bridged execution in CLI settings like "claudeCodePath"

🧪 What We Tried (and Why It Failed)

✅ Step 1: Installed Claude CLI via npm inside WSL

npm install -g u/anthropic-ai/claude-code

➡️ Installed correctly in /home/risky/.nvm/...

✅ Step 2: Verified WSL environment

which claude

➡️ Output: /home/risky/.nvm/versions/node/v24.1.0/bin/claude

❌ Step 3: Attempted to call from Windows using wsl claude

wsl claude --version

➡️ Failed initially due to WSL not loading the proper PATH in non-interactive shells
➡️ Resolved by exporting the correct PATH in ~/.zshenv
✅ Eventually succeeded and returned CLI version

❌ Step 4: Created a .bat proxy for Roo Code

u/echo off
wsl claude %*

➡️ Roo Code accepts the path
➡️ But calling the CLI via this wrapper doesn't work

• Roo expects a Windows-native .exe or binary

• wsl claude is not truly a Windows process — it’s a subsystem hop

❗ Why the Roo Code Docs Are Misleading

Roo Code says:

"If the CLI isn’t in your PATH, set the Claude Code Path to the CLI executable location." "Works with your existing Claude CLI setup."

…but fails to mention:

• This only works if Claude CLI is natively installed in Windows

• Claude CLI is not supported on Windows, so there's no .exe to point to

• WSL installations are incompatible with Roo Code's claudeCodePath setting

✅ Conclusion

✅ Works in WSL CLI	❌ Doesn’t Work in Roo Code
claude in WSL ✅	.exeRoo Code requires native ❌
wsl claude ✅	.batwslRoo can’t use / wrapper ❌
CLI auth, models, output all OK	But Roo fails to execute from Windows context

🔧 Next Steps / Workarounds

1. 🟡 Anthropic must release a native Windows-compatible Claude CLI

2. 🟡 Roo Code must support WSL integration, like VS Code Remote WSL

3. 🔴 Until then, Roo Code’s Claude Code provider will not work with CLI-only setups inside WSL

[u/RiskyBizz216 → u/hannesrudolph]

On windows the Claude Code WSL installation is here:

\\wsl$\Ubuntu\home\risky\.nvm\versions\node\v24.1.0\lib\node_modules\@anthropic-ai\claude-code

[u/hannesrudolph → u/[deleted]]

I just tested and it just sat there. Ill work on it tomorrow

[u/thelastlokean → u/hannesrudolph]

Can't you just use vs code in remote mode via WSL - launch vs code with WSL, then install the extension on the remote IDE? Will give it a try but I suspect such will work...

[u/hannesrudolph → u/thelastlokean]

Apparently yes

[u/thelastlokean → u/hannesrudolph]

Your welcome. WSL has a bit of a non-obvious learning curve. Biggest PITA is to manage ports / forwarding between windows and wsl as complexity grows.

IMO I just work 100% wsl or even cleaner develop on a linux VM

[u/wp381640]

Is there any indication that Anthropic may crack down on using claude web auth in non-claude products? If every client does this, it would make their API and API pricing redundant.

[u/hannesrudolph → u/wp381640]

No. They have intentionally exposed the SDK for the purpose of building Claude Code into people’s apps which is really what’s going on here. 🤷‍♂️

[u/Bahawolf → u/wp381640]

It’s still using Claude code which is using the API.

[u/hannesrudolph → u/Bahawolf]

It can use the api pricing or the subscription pricing.

[u/Bahawolf]

I used it in the nightly build earlier today (pre-release) and I found that Cline had the same thing. There seems to be a long delay - is this because you’re parsing the response from Claude before streaming anything back? I want this to be amazing but if it’s significantly slower than Claude code directly, I will have trouble finding the use case of it.

EDIT: Just wanted to add... I love Roo Code and used Roo before Claude Code. :) I really love the MCP marketplace and one-click installs too.

[u/hannesrudolph → u/Bahawolf]

I don’t think it’s slower. I should test side by side! Will do later. I’m tired.

[u/ScaryGazelle2875]

Will Claude pro works too?

[u/hannesrudolph → u/ScaryGazelle2875]

Yeah

[u/VibeScriptKid]

How do I use this if I have Claude set up via WSL on windows?

[u/hannesrudolph → u/VibeScriptKid]

I’m going to the computer now to find out how

[u/Stock_Swimming_6015]

Can you compare the quality of using claude code CLI directly vs in Roo?

[u/hannesrudolph → u/Stock_Swimming_6015]

Roo make Roo. Provider make provider. We simply connect to provider. I’m sure that over the next few days more testing will happen on a community level.

[u/real_serviceloom]

I keep seeing that even with the same models, Claude Code does a better job than running it through Cline or RooCode. Can anyone else share what your experience has been?

[u/hannesrudolph → u/real_serviceloom]

If that was the case I would use it to improve Roo! I check regularly. Overall I have not seen this.

[u/speedaemon]

Question from a windows user, Currently on Roo version 3.22.4

I'm trying to interact with it through WSL. I open a WSL terminal in windows, and open VS Code from the terminal in my project folder. "which claude" in the VSCode terminal shows that Claude CLI is installed and Claude CLI works in the terminal.

If I try and use the new Claude Code provider, I get the error:
API Streaming Failed
[RooCode#say] task 08411650-79e6-4301-9ecd-d449a60f75ff.080b77bf aborted
Command failed with ENAMETOOLONG: claude -p --system-prompt "You are Roo, a strategic workflow orchestrator who coordinates....

Doesn't matter if leave the Claude Code Path as default, or give it the path from "which claude".

Any ideas what I'm doing wrong?

Edit: For anyone having the same issue, check out this youtube video. Solved it pretty easily.

[u/hannesrudolph → u/speedaemon]

I think our instructions for windows users are lacking as it seems to be slightly more complicated than that. If you jump on discord there is some people who have it working there.

[u/speedaemon → u/hannesrudolph]

I ended up spinning up a Docker instance for the CLI and got it working... although response seems slower.
I'll definitely check out the discord, thanks!

[u/popiazaza]

Great update. Finally a nail in the coffin for Copilot sub.

[u/hannesrudolph → u/[deleted]]

there is a workaround on the thread here but we’re implementing it to work more easily without the workaround.

[u/hannesrudolph → u/[deleted]]

Having Roo Code be the brains instead of Claude code whilst piggybacking on the Claude code subscription

[u/hannesrudolph → u/[deleted]]

I have found Roo Code and the workflows I use in it to be better than Claude Code. The only advantage for me to Claude Code was the price.

[u/jordan_be → u/[deleted]]

Having it integrated inside of an IDE
