{Expltools: Development tools for expl3 programmers}
{Static analysis tools are invaluable for catching bugs early and
improving code quality. However, the highly dynamic nature of
\TeX{} has long posed a barrier to static analysis.

Expl3 is a high-level programming layer built on top of \TeX.
Originally developed to simplify the \LaTeX{} kernel, it is now
widely used by package authors across \LaTeX{} and other \TeX{}
formats. While it retains much of \TeX's flexibility,
real-world expl3 code tends to follow more predictable patterns,
making it far more amenable to static analysis.

In this talk, I introduce \emph{expltools}\Dash a long-overdue
addition to the expl3 programmer's toolbox. Designed to support
semantic analysis, it brings clarity and structure to a domain
traditionally resistant to static tooling. I present the current
state of the project, focusing on its design, practical usage,
and validation on real-world expl3 packages.
