자바 스크립트 + jQuery, 1362 1258 바이트

축소기를 사용하여 골프 :

$(function(){function e(){function e(e,t){$("#input").val("@"+$(e).parents(".user-container").find(".username").eq(0).text()+" "+t),$("#sayit-button").click()}var i,a=$(t),s=a.map(function(e,t){return t.id}),r=s.slice(-1)[0]
n!=r&&(i=a.slice($.inArray(n,s)+1),n=r,i.map(function(t,n){var i,a,s,r,o,u,c,f=n.textContent.match(/!!(\S+)(?:\s+(\S+))?/)
if(f){switch(i=f[1],a=f[2],s="codegolf",0==i.indexOf("meta")&&(s="meta."+s,i=i.slice(4)),r="?site="+s,c=0,i){case"newest":o=["questions","&order=desc&sort=creation"],u=function(e){return e.items[0].title}
break
case"questioncount":o=["info",""],u=function(e){return e.items[0].total_questions}
break
case"tag":if(!a){c=1
break}o=["tags/"+a+"/wikis",""],u=function(e){return 0==e.items.length?"Tag not found":e.items[0].excerpt}
break
case"featured":o=0==s.indexOf("meta.")?["questions","&tagged=featured"]:["questions/featured",""],u=function(e){var t=e.items.length
return(e.items.has_more?"more than ":"")+t}}c?e(n,"You have not provided enough arguments"):o?$.get("http://api.stackexchange.com/2.2/"+o[0]+r+o[1],function(t){e(n,u(t))}):e(n,"The command "+i+" does not exist")}}))}var t="[id^=message-]",n=$(t).eq(-1).attr("id")
new MutationObserver(e).observe($("#chat").get(0),{childList:!0,subtree:!0})})

Stack Exchange의 jQuery 작동을 사용하여 브라우저에서 직접 스크립트를 실행해야합니다.

1. http://chat.stackexchange.com/rooms/14697/chatbot-challenge-on-programming-puzzles-code-golf를 엽니 다 .
2. 콘솔에 위 코드를 붙여 넣기
3. 채팅에 몇 가지 명령을 입력하십시오

훨씬 더 골프를 칠 수는 있지만 귀찮게 할 수는 없습니다.
