}🟢explain_player(player, stat)
Why our model prices an NFL player's Kalshi prop strikes where it does this week: the projection, The Ladder's verdict, the widest published gap, and what the model does not account for (our number only where calibrated, 30–70%). Use for "why do you price <player> there", "explain <player>'s prop".

}🟢compare_players(players, scoring, platform)
Compare 2–4 NFL players this week: every Kalshi prop strike each has, the best price per side across venues, our probability where we publish one, and a ranked verdict on whose price the model disagrees with most, and on which strike. Use for "<A> or <B> this week", "compare <A> and <B> props", "who has the better prop, <A> or <B>", "<A> vs <B> receiving yards".

Use for "show my fantasy team" and "what is Kalshi pricing my starters at". Give a Sleeper username (and a league name if you have several): your roster, each starter's opponent and kickoff, OUT and QB-gate flags, and every Kalshi prop strike on him this week with the best price per side.
