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

- `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.
