How to Prevent Infinite Loops and Credit Loss in Your Agent

I was testing an agent I built ( https://chat.lindy.ai/eva-olssons-workspace-2/lindy/design-research-assistant-68a45b4250ce5367272fe522/editor ) and noticed it looped continuously through my Google Drive repository, repeating the same response. I managed to stop it, but my credits dropped from 398 to 51 in just a few minutes. Any advice on how to avoid this happening again? Was the looping causing the credits to run out? Is there a way to set limits or detect runaway loops before they burn through credits? Thanks in advance!
