I thought you did not speak about the old Wikimedia Tools Labs (which was extinguishing) but the new farm and that this was for finally adopting a name after the migration. "toolforge" seems very unrelated to this farm, even if it has a central catalog of hosted tools. Why a new domain ? Can't that be compatible wit hthe base domain for all individual tools? Do you intend to do this catalog also for tools that are in fact hosted also in other farms (e.g. on Wikimedia sites, or even GitHub, or in each chapters' domains, and possibly also for Wikia, and other sites using Mediawiki , or Wikimedia wikis such as Wikidata, Commons, and individual lingusitic editions of Wiktionary, possibly also the OSM wiki?)
Your project was not correctly described, so the confusion is understandable, and this should be clearified if you intend to choose a name, because you did not specify the scope of tools that the catalog would cover: is it a companion of the Mediawiki site?
Or will it be even larger, to cover other things than just MediaWiki-based wikis (e.g. other sites used by the WMF or its chapters and parters, running with other CMS systems, such as Phabricator, and even other wiki engines, or online forums, and extensions or bots for interacting with social network?)
