VS Code extension fails to activate on Windows: hardcoded Linux path in extension.js

Extension version: 2.1.129 (win32-x64)
OS: Windows 10 Pro 10.0.19045
VS Code: System Installer

Error

Extension ^Gnthropic.claude-code fails to activate on startup with the following error:


2026-05-06 11:49:17.025 [error] Activating extension Anthropic.claude-code failed due to an error:
2026-05-06 11:49:17.025 [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 Object.<anonymous> (c:\Users\..\.vscode\extensions\anthropic.claude-code-2.1.129-win32-x64\extension.js:102:5407)


Root cause

A Linux CI build path (ile:///home/runner/work/claude-cli-internal/...) is hardcoded in extension.js. This path is invalid on Windows, causing the extension to fail during activation.

Symptom

Clicking the Claude Code icon in the Activity Bar shows:

command 'claude-vscode.editor.openLast' not found

This is because the extension never activates, so no command handlers are registered.

Workaround

Using claude CLI directly in the VS Code integrated terminal works fine.
