The keystone of the pack. Interviews the user once and writes a shared company-profile.md that every other skill reads, so they know the user's priorities, VIPs, working hours, tone, and tools without asking again. Claude should use this skill when the user installs the pack, says "set up my skills", "onboard me", "configure the pack", "build my profile", "update my profile", or "/company-setup", or when another skill reports no profile is present.
