product-manager-toolkit skillA

product-manager-toolkit is agent-read markdown (skill) from majiayu000/spellbook: Use when the user needs product management workflows such as RICE prioritization, customer interview analysis, PRD templates, discovery frameworks, go-to-market strategy, feature prioritization, research synthesis, or requirements documentation..

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 majiayu000/spellbook/product-manager-toolkit@git:20260605.a09e45c
Exact content
mdr add majiayu000/spellbook/product-manager-toolkit@sha256:ef0f490e401d99bd

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.
