Agent-Facing Information Design in LLM Tool Registries

arXiv CS.AI

ArXi:2605.23916v1 Announce Type: cross LLM tool registries function as unregulated advertising platforms: providers write free-text descriptions that agents use for selection, yet no measurement infrastructure -- no viewability standard, quality score, or outcome audit -- exists to make this market accountable. We provide the first systematic framework, combining 17,700+ trials across five LLMs and ten domains with a constructive registry design prescription.
