Tools: check_citation search_cases
check_citation | Check one US legal citation, or a sentence holding a few: whether it exists in the sources Loupe checks, which case it is, and whether a pin cite falls inside the opinion. Give it exactly as written, with the case name and year if the document has them, because the commonest error is a real citation attached to the wrong case. params: citation* |
search_cases | Search the case names in Loupe's index, or look up the case a citation names. Give the parties' names, and the year if known. A case missing from the results may still exist. params: query*, year |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
