Symdex Code Search

SymDex is a code intelligence tool that helps Claude find definitions, trace call graphs, and search codebases by intent without reading entire files. It covers 21 languages including Python, Go, Kotlin, Swift, and even routes from frameworks like Rails and Spring. The big idea is token savings: you ask "who calls this function" or "find the JWT validator" and it returns the exact symbols instead of making Claude grep through everything. It tracks result quality with confidence scores and freshness markers, which matters when you're debugging. The context pack feature is smart for broader questions like "how does authentication work here" since it assembles evidence bundles under a token budget. Worth using whenever you'd otherwise burn context on exploratory file reads.
