worlds_search_knowledge

Search the multilingual Claude World, GPT World, and Grok World corpus. The default core scope is balanced at 18 CLI modules per product in each locale, so Claude archives cannot dominate retrieval. Request curriculum for provider-specific advanced lessons, editorial-archive for historical releases and older articles, or all only when intentionally searching everything. Returns bounded excerpts, commands when present, canonical links, sources, and freshness metadata. It never modifies state.

Parameters9

query	string	required	Natural-language task, concept, error, or exact CLI command.
worlds	array	optional	Optional canonical world filters: claude, gpt, or grok.
products	array	optional	Optional product filters such as claude-code, codex, or grok-build.
languages	array	optional	Optional locale filters: en, zh-tw, or ja.
content_types	array	optional	Optional content filters, for example tutorial or field-guide.
source_status	array	optional	Filter by provenance quality.
scope	string	optional	Retrieval collection: core is the balanced default; curriculum adds unique advanced modules; editorial-archive searches retained news, releases, and older material; all combines everything.
limit	integer	optional
offset	integer	optional
