What's Wrong?

When using Claude Code VS Code extension v2, the claudeCode.claudeProcessWrapper option doesn't work for me with the default non-terminal mode.

For instance, even when setting claudeCode.claudeProcessWrapper to a direct path of non-wrapped Claude binary, /Users/nekketsuuu/.volta/bin/claude, Claude keeps showing waiting messages like "Marinating..." after sending a question.

It may be interesting that, after closing the extension pane and re-opening the pane, it has a record for successful response in its "Past Conversations" history. So the extension seems to have an issue around displaying its response, I guess.

What Should Happen?

The response will be shown as usual.

Error Messages/Logs

I can't find any logs about this. I'd appreciate if anyone suggests how to show internal logs of the VS Code extension.

Steps to Reproduce

1. Install Claude Code VS Code extension v2.

2. Set up like below:

   "claudeCode.claudeProcessWrapper": "/Users/nekketsuuu/.volta/bin/claude",
   "claudeCode.environmentVariables": [
       {
           "name": "CLAUDE_CODE_USE_BEDROCK",
           "value": "1"
       }
   ],
   "claudeCode.useTerminal": false
   

   Actually I'd like to choose my wrapper command for claudeProcessWrapper, but I found that this issue still happens when I set it to the plain claude command.

3. Open the Claude Code VS Code extension pane.

4. Ask something.

5. It will only show several waiting messages.

I found that this was caused by my misconfiguration of claudeProcessWrapper.

First, I found that the extension logs can be seen by: Command + Shift + P -> "Developer: Open Extension Logs Folder" -> "Anthropic.claude-code/Claude VSCode.log". It has a log for the exact command which is launched by the extension, and it turned out that claudeProcessWrapper is used as a prefix for claude, like wrapper-command claude --any-other-options. The actual command is like below:

[info] From claude: Spawning Claude Code native binary: /Users/nekketsuuu/.volta/bin/claude /Users/nekketsuuu/.vscode/extensions/anthropic.claude-code-2.0.28-darwin-arm64/resources/native-binary/claude --output-format stream-json --verbose --input-format stream-json --append-system-prompt 

So, after I modified claudeCode.claudeProcessWrapper to follow this rule, the extension started to work properly.

@nekketsuuu Looks like behaviour is not consistent between platforms. On Windows I get

2025-10-29 09:03:39.828 [error] Error spawning Claude (on channel lb2qcs79kfc): ReferenceError: Claude Code native binary not found at <<<verbatim contents of claudeCode.claudeProcessWrapper>>>. Please ensure Claude Code is installed via native installer or specify a valid path with options.pathToClaudeCodeExecutable.

[nekketsuuu]

It looks like a different problem from mine. The error message shows that a binary specified by claudeCode.claudeProcessWrapper is not an executable. For instance, I needed to specify the absolute path to the wrapper.

If your problem isn't resolved, I recommend to open a new issue.

I'm seeing similar behaviour, but on Linux. I'm running Claude Code on an Ubuntu server and using the VS Code extension on my desktop. It worked at first, but now the Claude panel in VS Code just sits on “marinating…” / waiting after I send a prompt and never shows a reply, even though it sometimes appears in the history after I close/reopen the panel. At the same time, if I use Claude Code in the integrated VS Code terminal instead, the terminal output starts visually glitching (flickering / rapid redraw). No clear error logs.

[nekketsuuu]

That bug is different from this issue's one according to the behavior. I recommend to search other issues or open a new issue.
