Tool calls keep failing

Support Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Everytime Auto model decided to edit the code almost 1/3 to 1/2 of its tool calls silently fail and it continues as if nothing happened breaking the repo in the process.

I noticed heavily increased tool call failures on Auto today.

I know tool calls might not necessarily be fixable from Cursor’s side as each model excels more than the previous in tool calls, however the models should be trained to retry instead of silently failing (and hiding) failures.

Steps to Reproduce

Ask Auto mode to do fix a bug or add a feature

Expected Behavior

Working tool calls or at least retries instead of hiding failures

Operating System

Windows 10/11

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. The issue where the agent doesn’t retry after tool call errors is something the team is working on.

To help us diagnose your specific case, could you share:

  1. Console logs (Help > Toggle Developer Tools > Console) from when the tool calls fail
  2. An example task that fails most often
  3. Which model Auto mode picked at the time of the failures (shown in the chat)

While the team is improving the retry logic, please try selecting a model manually instead of Auto and see if the failure rate changes for specific models.
