A huge, convoluted codebase they'd taken over. One prompt in Cursor's Plan mode found the bugs and planned the fix, then the agent made it, where the client's previous team hadn't.
Result Plan mode found every bug in one prompt
“it found all the bugs, created a plan to fix them, it looked good, and I had the agent create the fix. It took 30 minutes.”

They had Cursor evaluate a huge, convoluted codebase they’d taken over, using its Plan mode to find all the bugs and create a plan to fix them, then had the agent implement the fix.
The whole process took 30 minutes, succeeding where another company handling the same client’s project without AI tools had been unable to fix the bugs the client had reported to them.
Point [your coding agent] at a convoluted or unfamiliar codebase and ask it to use its planning mode to find bugs across the whole project and draft a fix plan before touching any code. Review the plan, then have it implement the fixes.
