Flag ad formats that are a poor fit or commonly misused for a given objective and platform - formats the objective does not even expose, formats built for a different funnel stage, formats the team cannot produce - then, post-launch, separate a format problem from a creative or targeting problem. Use whenever the user asks which ad format to use, mentions carousel, Stories, in-feed vs in-stream video, a funnel-stage mismatch, a pre-launch format check, or says a format 'isn't working' - even if they never say 'format fit'. Covers B2B and B2C, with explicit launch blockers. Do NOT use to choose the channel itself (mbfinotti/advertising-skills@ad-platform-selection) or to brief the creative (mbfinotti/advertising-skills@ad-creative-brief).
