Find the downloaded file named `brainstorm-system.zip`. Safely extract it without overwriting existing files, verify that the extracted package contains `brainstorm-system/BRAINSTORM.md`, and move the extracted `brainstorm-system` folder to a stable, appropriate, user-owned location. Create the platform-correct minimal user-level skill or command named `brainstorm`, invoked as `/brainstorm`, and make it point to the absolute path of the extracted `BRAINSTORM.md`. Do not point the skill or command at the ZIP. On agents or platforms without skills, create the equivalent user-level command if supported. Do not overwrite an existing package, skill, or command without asking me first. When finished, report the package path, command file path, and the absolute `BRAINSTORM.md` path.
