The "adminstats" tool (https://admin.toolforge.org/?tool=adminstats) has the code for https://en.wikipedia.org/wiki/User:AdminStatsBot however the source code files do not have a license specified nor is it in the tool's toolinfo.
Per Toolforge rules, all code must be available under an OSI license: https://wikitech.wikimedia.org/wiki/Help:Toolforge/Rules#Toolforge_rules
@JamesR, can you specify a license that you'd like to have the code be available under?
This came to my attention because of https://en.wikipedia.org/wiki/Wikipedia:Bots/Noticeboard#General_query where the bot has broken because of recent API changes, but because the bot's code has no license specified, it's not really feasible for anyone else to help fix it.
