Known Issues

• nano-manus is extremely unstable! My guess is gpt-4o is not that good at tool use.
• Unable to exit: seem like some MCPs will cause the problems of unable to exit the program when all the tasks were done.
• nano-manus will operate files and run command on the current dir of your local computer, make sure you don't run it on some important folders.
