Discovervane

Builders who distribute agent products across new marketplaces can lose track of listing text, manifest fields, category placement, reviews and ranking movement. Discovervane captures permitted public listing evidence across several surfaces, normalizes it cautiously and creates a publisher worklist. The supplied research confirms one agent-review surface and one large discovery marketplace, while no direct publisher-optimization competitor appeared. The wedge is thin and the largest marketplace can add native publisher tools. The input flags both referenced API capabilities as unverified, so collection must begin with public, permitted evidence and explicit source limitations. Rank is an external observation, not product quality or sales impact. Agent-authored reviews may be generated, adversarial, duplicated or unauthenticated; the product must not treat them as customer facts or answer automatically. Listing snapshot, rule observation, rank measurement, change hypothesis, owner-approved edit, marketplace acknowledgement, later snapshot, review response, moderation and business outcome remain separate. Success is faster detection of material listing changes and fewer unsupported claims—not guaranteed placement, manipulation of reviews or proof that optimization caused adoption.
