Automatically add "c" to terminal commands in chat

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The AI assistant in Cursor IDE automatically adds an incorrect “c” prefix to Python commands, causing terminal execution failures.

Steps to Reproduce

Ask the AI assistant to run a Python command
The assistant uses the run_terminal_cmd tool
The command is automatically modified from py to cpy
Terminal returns: ‘cpy’ is not recognized as a command

Expected Behavior

Commands should execute as py -c “…”
Terminal should successfully run Python commands
No automatic prefix modification should occur

Additional Information

When opening the cursor, the first 1-2 times the commands are executed without a bug, but then the cursor starts adding the letter “c”.

Does this stop you from using Cursor

No - Cursor works, but with this issue
