+After completing this task, evaluate if extractable knowledge emerged:
+- Non-obvious solution discovered through investigation?
+- Workaround for unexpected behavior?
+- Project-specific pattern learned?
+- Error required debugging to resolve?

+If high-value (recurring, broadly applicable): Consider skill extraction.
