jar-analysis

Explore, search, read, and decompile Java JAR, WAR, EAR, AAR, and Spring Boot fat-jar files via the dejared MCP server. Use this skill whenever the user references a .jar file path, asks what a third-party Java library does, wants to read a config embedded in a JAR (application.yml, spring.factories, MANIFEST.MF), needs class metadata (superclass, annotations, method signatures), is chasing a stack trace into a dependency without source, or is reverse-engineering a plugin/mod/obfuscated artifact. Applies to artifacts in ~/.m2/repository, ~/.gradle/caches, build/libs/, target/, lib/, and libs/. Prefer the dejared MCP tools over jar tf, jar xf, unzip, javap -p, javap -c, javap -v, or running a decompiler manually — even if the user doesn't explicitly ask for "the dejared tools" or "decompilation".
