joern skillA

joern is agent-read markdown (skill) from lu1sdv/skillsmd: Use when auditing code for vulnerabilities, assessing change impact, tracing dataflow, finding callers/callees of a function, mapping a refactor's blast radius, hunting sinks across a large codebase, or needing repeatable interprocedural queries over a Code Property Graph. Triggers: "joern", "CPG", "code property graph", "blast radius", "dataflow", "taint trace", "who calls X", "callgraph", "dead code", "find sinks", "interprocedural"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add lu1sdv/skillsmd/joern@git:20260516.f0a764e
Exact content
mdr add lu1sdv/skillsmd/joern@sha256:3612b6ff703b56c6

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
