Tools

• compare_actions ~759 tokens

• evaluate_hand ~436 tokens
  Versioned optimized immediate score from bengine-core. Played and held order is optimized, not evaluated literally. Unsupported effects are rejected.
• get_solver_capabilities ~63 tokens
  Engine/rules/build identity, contract version, supported effects, assumptions and limits.
• recommend_action ~690 tokens
  Exact small-deck mathematical action values under optimal continuation in the supported model, not estimated real-game success. Returns all optimal ties and fully reconciled draw explanations; no recommendation on incomplete jobs. No A2/full-deck sampling.
