Agent Skills: dead-code

Find dead Java code by static reachability from entry points. Parses the sources, builds the method call graph, walks it from real entry points (main, Spring web/lifecycle/scheduler handlers, JUnit tests, framework callbacks), and renders a light-theme website with summary cards, a reachable-vs-dead chart, and a grouped list of every unreachable method and dead class. Use when the user runs /dead-code or asks to find dead, unused, or unreachable code, or which methods and classes are safe to delete.
