LegalBench

Fits contract-review, compliance and legal-research assistants that must classify clauses or apply a rule to facts. Borrow its six-way reasoning taxonomy (issue, rule, conclusion, application, interpretation, rhetoric) and its short hand-written task cards.

What it asks the agent to do

  • spot the legal issue in a short fact pattern
  • recall a legal rule and apply it to facts
  • classify a contract clause or privacy-policy statement
  • decide whether a clause creates a given obligation
  • interpret a statutory or contractual text

Caveats

Question-answer only, no tools or multi-step work; 162 tasks are mostly US-English classification with per-task licenses inherited from upstream datasets (CUAD, MAUD, CaseHOLD etc.), so license is mixed; top models score near 89 percent on the Vals leaderboard, so it is close to saturated.
