GF Agent Toll accepts common aliases/camelCase/snake_case request shapes through the negotiation endpoint and returns exact missing fields instead of hard-failing supported business intents.
The capability index expands discovery coverage using only real GF services and supported protocol surfaces; it does not fabricate customers, reviews, traffic, or market outcomes.
