Wikipedia discovery

Use the current wiki hostname (e.g. en.wikipedia.org) for all API requests unless you intentionally switch language wiki.

Helping someone learn (user-facing)

When the user wants to learn about something, steer them toward concrete articles (and sections by heading when helpful). In natural language:

• Name articles by title and briefly say why each is relevant to their question.
• Do not paste full URLs, do not use markdown links, and do not bullet raw links—readers use url_change on their own; your job in chat is titles + relevance only.

Behind the scenes, when it is time to open the mirror, use message_parent with a full Wikipedia url (optional # section / anchor per below); that string is not for display in the user-visible reply.

I have a phrase / topic — find articles

Search the index, return ranked titles/snippets, optionally narrow namespaces. Prefer REST search for simple JSON cards; use Action API list=search when you need Cirrus options, generators, or wikitext-era fields. Paging: Action list= modules return continue — merge those params on the next request until absent. REST search may use limit / offset where supported.
