What's Wrong?

Windows 11, Node v24.15.0, using nvm acceptEdits mode is enabled node -e "fs.writeFileSync(...)" works Claude Code does not make tool calls, it only returns text Same issue in both CLI and VS Code extension

I have tested this issue across multiple environments on Windows:

WSL Command Prompt (cmd) PowerShell Windows Terminal VS Code with the Claude Code extension

The behavior is consistent in all cases — Claude Code does not trigger tool calls and only returns text.

However, when using the same setup on macOS, everything works as expected and tool calls are executed properly.

I am currently using a company-managed Windows machine. Could there be any restrictions (e.g., security policies, permissions, antivirus, or system configurations) that might be preventing tool execution?

What Should Happen?

When running Claude Code with acceptEdits mode enabled, the system should execute tool calls instead of only returning text responses.

TL;DR

Investigate Windows-specific security policies or restrictions that might prevent tool execution, as the issue only occurs on Windows and not on macOS.

Guidance

  • Check company-managed Windows machine's security policies and antivirus settings to see if they are blocking tool execution.
  • Verify file system permissions to ensure Claude Code has the necessary access to execute tool calls.
  • Compare the environment variables and system configurations between the working macOS setup and the non-working Windows setup to identify potential differences.
  • Test Claude Code on a non-company-managed Windows machine to isolate if the issue is specific to the company's security policies.

Notes

The issue seems to be specific to the Windows environment, and the fact that it works on macOS suggests that the problem might be related to Windows-specific security restrictions or configurations.

Recommendation

Apply workaround: Investigate and potentially modify Windows security policies or restrictions to allow tool execution, as the issue is likely related to the company-managed Windows machine's configuration.
