industry-map skillB

industry-map is agent-read markdown (skill) from yennanliu/investskill: Map an industry's supply / value chain as a directed graph — upstream to downstream — to locate a company's position, find chokepoints and margin pools, and surface second-order investment ideas.

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/industry-map@git:20260924.b016647
Exact content
mdr add yennanliu/investskill/industry-map@sha256:c06358ac98d9625b

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.
