+      description: |
+        This project aims to improve Clang’s error recovery infrastructure for interactive compilation environments such as Clang-Repl. While Clang provides robust error recovery for normal compilation, its current design is primarily built around a single compilation flow and does not always behave consistently in incremental compilation scenarios.
+        The goal is to ensure that failed inputs do not improperly affect future semantic analysis while preserving Clang’s existing behavior and assumptions.
+      mentors: Vassil Vassilev, Aaron Jomy
