What's Wrong?

Extension fails to activate on Windows with the following error:

TypeError: The argument 'filename' must be a file URL object, file URL string, or absolute path string. Received 'file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs' at Module.createRequire (node:internal/modules/cjs/loader:1922:13) at Object.<anonymous> (c:\Users\ivanc.vscode\extensions\anthropic.claude-code-2.1.136-win32-x64\extension.js:103:5579)

A Linux CI runner path is hardcoded in the Windows build (win32-x64), causing createRequire to fail. Commands are never registered, so clicking the Claude Code icon throws command 'claude-vscode.editor.openLast' not found.

Steps to reproduce:

  1. Install Claude Code v2.1.136 (win32-x64) in VS Code on Windows
  2. Open any workspace
  3. Click the Claude Code icon in the activity bar

Expected: Extension opens normally Actual: command 'claude-vscode.editor.openLast' not found

Environment:

  • OS: Windows 11 Pro (10.0.22621)
  • VS Code: (your version)
  • Extension: anthropic.claude-code-2.1.136-win32-x64

Workaround: Install previous version via Extensions → gear icon → "Install Another Version"
