## Tools (as reported by the server, not verified)

- `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
- `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.
