Commands

The images are from when she used text commands. With Discord moving away from them, everything is slash commands now.

/define <word> - Natsuki knows the definitions of many Mahjong words and can recall them with this command. She also has a built-in dictionary for a large number of English words as an added bonus. If you don't specify a word, she'll pick a random Mahjong term that she knows. For a list of all the terms, check the commands/define.js file.
/explain <topic> - Natsuki has some longer explanations for common topics in Mahjong. They're a bit simplified, but good starting points if new players are asking about them. You can see a list when you try to call the command.

/link <site> - Natsuki has a number of commonly referenced pages related to Mahjong that she can recall with this command. If you don't specify a site, she'll give you a random one. For a list of all the sites, call /link list or check the commands/link.js file.
/efficiency <hand> - With this command, Natsuki will analyze the ukeire of each discard in a hand and output them similar to tenhou.net/2/. If the hand only has 13 tiles (or 13 minus a multiple of 3) she'll just tell you the ukeire. The hand format is the same as in /2/.

/minefield - Minefield Mahjong is a 1v1 variant where each player gets 34 tiles and has to create a tenpai hand with them. Natsuki will generate 34 tiles with this command, arranged in three rows, as a fun activity.
/convert <message> - Natsuki will parrot the message, swapping any hand prefixed with ! with emoji. For example, "My favourite tile is the !4z, but my favourite set is !234s."

/rate <player> - Natsuki will check Nodocchi and tell you how many games that player has played on Tenhou, and what their R is at. If they haven't played in Tokujou, she'll say they have less than 1800R. If they have >1800R in sanma, she'll point that out, too, just to shame them. She'll also tell you when the last time they played was.

/randomhand - Natsuki will simply generate a random hand of 14 tiles. Alias: !hand
/randomtile - Natsuki will pick a random tile.

/dice - Natsuki will roll 2d6, and tell you which player the wall is broken in front of.
/translate <text> - Natsuki will replace most Japanese mahjong terms in the given text with English equivalents.
/score <han> <fu> <dealer> <aotenjou> - Natsuki will convert the han and fu to a score with any of the modifiers. Dealer to change it to a dealer score, aotenjou to remove the limiting hands.
