data-linkage skillA

data-linkage is agent-read markdown (skill) from hellodqy/mastermind-bug-bounty: Connect response values to later request parameters and keep expanding the attack graph after each finding..

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 hellodqy/mastermind-bug-bounty/data-linkage@git:20260709.c284c01
Exact content
mdr add hellodqy/mastermind-bug-bounty/data-linkage@sha256:007837734a130e74

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.
