list_benchmarks
A compact index of what OpenChainBench measures. One short row per benchmark: slug, title, category, the metric, the current value and who leads it. Use when the user asks what is measured at all ("what does OpenChainBench cover?", "do you track bridges?"). When they ask a quest…
search_benchmarks
Ranks the benchmark catalogue against a question in the user's own words and returns the best few matches. Use this when somebody asks which provider, chain or service is fastest, cheapest, most reliable or best for something. Pass their phrasing through: provider names, chain n…
