What battle-card-builder does
Build a field-action competitive battle card from public evidence: **use or gather evidence → search plan (if gathering) → draft card with per-claim labels → appendix → next-step options.** A battle card is the artifact a rep opens mid-deal, not a research report — it must fit thirty seconds, every claim must survive being said out loud to a hostile audience, and every claim therefore carries a source URL, a date, and a Fact/Inference/Assumption label. Most battle cards in the wild are unlabeled inference; this skill exists because of what it costs a rep when one of those turns out wrong.
