+A command error was detected. Consider logging this to .learnings/ERRORS.md if:
+- The error was unexpected or non-obvious
+- It required investigation to resolve
+- It might recur in similar contexts
+- The solution could benefit future sessions

+Use the self-improvement skill format: [ERR-YYYYMMDD-XXX]
