+      status: Ongoing
+      description: |
+        This project focuses on improving the reliability and safety of automatically 
+        generated derivative functions in Clad. Some mathematical operations in these 
+        functions can produce undefined behavior when given inputs outside their 
+        valid domains, which may lead to incorrect results or program crashes. The goal 
+        is to implement a safe math mode using the CLAD_SAFE_MATH flag, which adds 
+        optional input checks and returns well-defined values like NaN when invalid 
+        inputs are detected. The project also includes debugging utilities and 
+        performance testing to ensure that enabling safety does not significantly 
+        affect efficiency. This work will allow Clad-generated functions to behave 
+        predictably and help developers identify and fix issues more easily.
