In recent years, compositional symbolic execution (CSE) tools have been growing in prominence and are becoming more and more applicable to real-world codebases. Still to this day, however, debugging the output of these tools remains difficult, even for specialist users. To address this, we introduce a debugging interface for symbolic execution tools, integrated with Visual Studio Code and the Gillian multi-language CSE platform, with strong focus on visualisation, interactivity, and intuitive representation of symbolic execution trees. We take care in making this interface tool-agnostic, easing its transfer to other symbolic analysis tools in future. We empirically evaluate our work with a user study, the results of which show the debugger's usefulness in helping early researchers understand the principles of CSE and verify fundamental data structure algorithms in Gillian.
