Reads a backlog and a written strategy document, and returns the backlog ranked against that strategy, with each ranked item citing the exact strategy passage that justifies its position. Items the strategy document doesn't cover get flagged as unscored rather than ranked or given an invented framework score. Use whenever the user says "rank this backlog against our strategy", "prioritize this backlog", "which of these should we build first", "/backlog-prioritization-strategy", or pastes a backlog alongside a strategy doc and asks what to build first.
