Your AI gets these debugging superpowers:
debugger_attach - Connect to a processdebugger_set_breakpoint - Set breakpointsdebugger_continue - Resume executiondebugger_step_forward - Step forwarddebugger_step_backward - โช Step backward in timedebugger_get_stack_trace - Get stack tracedebugger_get_variables - Read memorydebugger_export_trace - Export execution traceYou: "My Rust program crashes at runtime. PID is 12345"
AI:
I'll attach and debug that for you.
๐ Attached to process 12345
๐ธ Captured snapshot
๐ Stack trace shows crash at unwrap() on None in process_data()
