product-brainstorming skillA

product-brainstorming is agent-read markdown (skill) from martineserios/thebrana: Brainstorm product ideas, explore problem spaces, and challenge assumptions as a thinking partner. Use when exploring an opportunity, generating solutions, or stress-testing an idea before converging on a direction..

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.
