Selection evidence

Confusable tool pairs.

18 pairs where similar names or overlapping descriptions may send an agent toward the wrong tool.

Tool A	Tool B	Confidence	Why they collide
`sleeper_get_user_leagues`	`sleeper_get_league_users`	high	Exact token swap; one takes a user_id to return leagues, the other takes a league_id to return users. A task like 'get the leagues and users for this sleeper league/user' or just 'get user's leagues' can cleanly select the wrong member since names differ only in noun order.
`formulae_get_races`	`formulae_get_race`	medium	Singular/plural pair with identical tokens except count. A task like 'get the race' or 'get Formula E race details' is ambiguous between listing races and fetching one race; descriptions differ mainly by lists-vs-single.
`f1_get_driver_standings`	`f1_get_constructor_standings`	medium	Both return F1 championship standings with identical schemas; only 'driver' vs 'constructor' differs. A generic task like 'get the 2024 F1 standings' without naming drivers or constructors fits both tools.
`chesscom_get_player`	`chesscom_get_player_stats`	medium	Both accept only a username and 'player' dominates the names. A task like 'get player X's ratings/statistics' could select the profile tool, which returns title and profile data but not per-time-control ratings.
`mlb_get_game`	`mlb_get_game_boxscore`	medium	mlb_get_game's description explicitly says it includes the box score, so a task like 'get the box score for game 775' can be satisfied by either tool; both take only game_pk.
`mlb_get_game`	`mlb_get_game_linescore`	medium	mlb_get_game already includes the line score per its description, so 'get the line score for game X' is ambiguous between the generic game tool and the dedicated linescore tool.
`mlb_get_game`	`mlb_get_game_play_by_play`	medium	mlb_get_game returns plays and all share game_pk; a task 'get the play-by-play for game X' could wrongly select the generic game tool since its description advertises plays.
`mlb_get_player`	`mlb_get_player_stats`	medium	mlb_get_player can hydrate stats while mlb_get_player_stats returns detailed stats; a task 'get stats for player X' may pick the profile tool, especially since both require only player_id.
`nhl_get_schedule`	`nhl_get_team_schedule`	medium	Both are 'schedule' tools with highly similar names. 'Get the schedule' without a team/date, or 'get the schedule for the Canadiens' (only team_abbrev given), can route to the wrong one; the team tool is monthly while the league tool is date-based.
`openliga_get_next_match_by_team`	`openliga_get_last_match_by_team`	medium	Identical names except 'next' vs 'last' with identical team_id schema. A task like 'what match does team X have' or 'get the match for team 405' is genuinely ambiguous about direction of time.
`f1_get_driver_standings`	`formulae_get_driver_standings`	medium	Both are 'Formula' driver championship standings; f1 is Formula 1 while formulae is Formula E. A task like 'get the Formula driver standings for 2024' matches both, and both definitions mention championship/season.
`formulae_get_driver_standings`	`formulae_get_team_standings`	medium	Same series, same championship_id schema; only 'driver' vs 'team' differs. 'Get the Formula E championship standings' fits both and an agent may default to drivers.
`formulae_get_race`	`formulae_get_race_results`	medium	Both take the same race_id and describe a single race; 'get the results/classification of race X' could select the race-details tool since its description covers sessions/schedule, or vice versa.
`lichess_get_user`	`lichess_get_users_status`	medium	Task like 'check the status of user X' or 'is X online' is ambiguous; get_user returns profile/account flags while get_users_status returns online status, and the names differ only by 'status'.
`opendota_get_player_heroes`	`opendota_get_heroes`	medium	A task like 'get the heroes for player 123' or 'list heroes with win rates' is ambiguous; one returns per-player hero stats, the other the global hero list, and 'heroes' dominates both names.
`f1_get_lap_times`	`nascar_get_lap_times`	low	Cross-series lap-time tools; a task saying only 'get lap times for the race' with no series does fit both, but descriptions and required params (season/round vs year/series/race_id) usually disambiguate.
`mlb_get_game_boxscore`	`euroleague_get_game_boxscore`	low	Both named get_game_boxscore across sports; a vague 'get the box score' without a league is plausible but the sport-specific params and context normally disambiguate.
`sleeper_get_user`	`sleeper_get_league_users`	low	'Get the users for this league' vs 'get this user' overlaps lexically, but schemas differ (username vs league_id) and the descriptions clearly separate profile from league managers.
