institutional-ownership skillB
institutional-ownership is agent-read markdown (skill) from yennanliu/investskill: Track changes in institutional holdings and identify smart money moves from 13F filings.
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 yennanliu/investskill/institutional-ownership@git:20260924.9644512mdr add yennanliu/investskill/institutional-ownership@sha256:9b499876d4c21242Pin 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.
