Terminal command execution failing - "no result from tool" error (Claude Sonnet 4.5)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

AI assistant (Claude Sonnet 4.5) cannot execute any terminal commands. All attempts to use the run_terminal_cmd tool fail with “Error: no result from tool. The user likely interrupted the tool call to send you a message” - even when no interruption occurred.

This completely blocks AI-assisted development workflows including builds, tests, and automated tasks.

Steps to Reproduce

  1. Open Cursor AI chat with Claude Sonnet 4.5 model
  2. Ask AI to execute any terminal command (e.g., “pwd” or “echo test”)
  3. Observe that command execution fails immediately
  4. Error message appears: “Error: no result from tool. The user likely interrupted the tool call to send you a message”
  5. Issue is reproducible 100% of the time with any command

Test commands that failed:

  • echo “Hello, this is a test command”
  • pwd

User confirmed NO interruption occurred.

Expected Behavior

Terminal commands should execute successfully and return output to the AI assistant. The run_terminal_cmd tool should work reliably for basic shell commands like pwd, echo, ls, gradle tasks, etc.

Thanks for the detailed bug report, @Ryota_Yamashiro! This is a known issue that the team is actively working on.

Temporary workaround while the fix is in progress: Downgrade to v1.5 (multiple users confirmed this works): https://cursor.com/download
