Use when

You have split a contract into provisions and need a type for each one.
Your input consists of commercial or employment agreements in English.

Avoid when

You need legal advice or an assessment of fairness or enforceability; this adapter only identifies the clause type.
You need to process an entire contract in one call; supply one provision at a time.
