Tools observed via MCP handshake

get_leaderboard — Models ranked by accuracy; defaults to all effort levels for compatibility.
list_providers — Provider ids, names, families and variant counts.
list_families — Model families, available efforts and best variants.
compare_models — Side-by-side core overall and per-size accuracy, cost, latency and token results for model or family names.
get_model_results — Accuracy, cost, latency and token use for one model, broken down by grid size.
list_puzzles — The benchmark puzzles with their ids and row/column clues.
get_puzzle — One puzzle, including the clue text models were prompted with. The reference solution is only included on request; some puzzles have several valid solutions.
check_solution — Check a grid against a puzzle's clues, using the same rule as the benchmark grader. Reports which rows and columns do not match.
get_puzzle_results — Per-model outcomes for one puzzle. Answers are omitted unless requested.
get_model_puzzles — Which puzzles one model solved, missed, timed out on, or has not run.
list_runs — Individual benchmark runs (one model on one puzzle), optionally with the raw prompt and model output.
