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".

Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
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".
