jwt-attack skillA
jwt-attack is agent-read markdown (skill) from hellodqy/mastermind-bug-bounty: Reason about JWT trust boundaries and whether token control can become privilege escalation..
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
mdr add hellodqy/mastermind-bug-bounty/jwt-attack@git:20260709.c284c01mdr add hellodqy/mastermind-bug-bounty/jwt-attack@sha256:1cecd554566c44aaPin 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.
