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

Latest version
mdr add yennanliu/investskill/institutional-ownership@git:20260924.9644512
Exact content
mdr add yennanliu/investskill/institutional-ownership@sha256:9b499876d4c21242

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.
