MANDATORY BEFORE CALLING: the user must have chosen BOTH sport and format for THIS tournament. If either is missing, ask instead of generating, or call get_supported_tournament_options to discover choices. Never infer sport or format from unrelated previous conversations, previous tool use, player/court counts or a default. 'Make a tournament for 20 players on four courts' requires clarification, not an Americano. Reuse choices explicitly confirmed earlier in this same tournament setup. Clarify individuals versus fixed teams when ambiguous. Use this when the user wants individual PADEL Mexicano standings from completed round scores, without generating another round. Supply config and all completed previousRounds. Each player receives their pair's rally points. Does not save or publish results.
Keep this value unchanged to reproduce a draw; change it only when requesting a new draw.
Completed rounds with scores. Player IDs are zero-based indexes in config.names. Preserve pairings and byes from the returned state; fill in scores. If an earlier score changes, discard later rounds before continuing.

}MANDATORY BEFORE CALLING: the user must have chosen BOTH sport and format for THIS tournament. If either is missing, ask instead of generating, or call get_supported_tournament_options to discover choices. Never infer sport or format from unrelated previous conversations, previous tool use, player/court counts or a default. 'Make a tournament for 20 players on four courts' requires clarification, not an Americano. Reuse choices explicitly confirmed earlier in this same tournament setup. Clarify individuals versus fixed teams when ambiguous. Use this when the user wants a PADEL Americano tournament (not pickleball; use generate_round_robin with rotating_doubles for pickleball rotating partners), rotating doubles partners, balanced rests and varied opponents. Plans rounds before play. Each entrant is an individual player. Always show the returned schedule in full, round by round: start time, court, both pairs and who rests. Never replace it with a summary. Set restMinutes when the user wants a break between rounds. After the schedule, pass on any warning about uneven rests and its suggested round counts. Does not save or publish an event; do not use for score-led Mexicano pairings.
| Argument | Type | Description |
|---|---|---|
| seed | integer | Keep this value unchanged to reproduce a draw; change it only when requesting a new draw. |
| count* | integer | |

'Make a tournament for 20 players on four courts' requires clarification, not an Americano. Reuse choices explicitly confirmed earlier in this same tournament setup. Clarify individuals versus fixed teams when ambiguous. Use this when the user wants a PICKLEBALL seeded or random single-elimination tournament bracket with byes, court assignments and provisional match times. Always show every returned match with its round, court and time; never replace it with a summary. Does not record winners, save an event or support double elimination.
| Argument | Type | Description |

'Make a tournament for 20 players on four courts' requires clarification, not an Americano. Reuse choices explicitly confirmed earlier in this same tournament setup. Clarify individuals versus fixed teams when ambiguous. Use this when the user asks to generate or run a PADEL Mexicano tournament. Creates round 1 from player count and courts, or the next round using all completed prior scores and individual standings. Always show the returned round in full: time, court, both pairs and who rests. Future pairings cannot be known in advance. If players must rest (count not a multiple of 4, or more players than court places), offer config.ranking: average (points per match) so extra rests do not cost anyone, and suggest a round count that gives equal rests. Set config.restMinutes when the user wants a break between rounds. Stateless: return the prior state with scores filled in. Does not save, publish or change a live tournament.

If either is missing, ask instead of generating, or call get_supported_tournament_options to discover choices. Never infer sport or format from unrelated previous conversations, previous tool use, player/court counts or a default. 'Make a tournament for 20 players on four courts' requires clarification, not an Americano. Reuse choices explicitly confirmed earlier in this same tournament setup. Clarify individuals versus fixed teams when ambiguous. For PICKLEBALL only: generate singles, fixed-team or rotating-doubles round-robin fixtures. Establish sport first; offer pickleball round robin or knockout, and padel Americano or Mexicano. Before calling, establish singles vs fixed teams vs rotating partners, whether the count means players or teams, full round robin vs a limited number of rounds, match duration and available session time. Never infer fixed teams from an individual player count. A full singles/fixed-team draw has n*(n-1)/2 matches and may require multiple court waves per round. Pickleball rotating partners use mode rotating_doubles here, with a numeric round count, not generate_americano. Do not promise everyone meets everyone in rotating doubles. Always show the returned fixtures in full, round by round; never replace them with a summary. Return total matches and estimated session length; if it exceeds the user's time, discuss a shorter partial draw rather than silently changing format. Free draft only; no saving or publishing.
| Argument | Type | Description |
|---|---|---|
| mode* | string | Required pickleball choice: singles, fixed doubles teams or rotating doubles with individual players. Ask when unspecified. Keep pickleball rotating doubles here; Americano is the padel tool. |
| seed | integer | Keep this value unchanged to reproduce a draw; change it only when requesting a new draw. |
Use for a generic tournament request with no confirmed sport or format, or to discover NextArena's supported sports, formats, entrant types and limits. Does not generate a tournament or select defaults. With no sport, ask Pickleball or padel first; with a confirmed sport, return only its formats. Do not display all formats as interchangeable across sports.
| Argument | Type | Description |
|---|---|---|
| sport | string | Only include a sport the user has selected for this tournament. Omit it when unknown; never infer it from unrelated previous requests. |
