diataxis-reference

Write, expand, or audit reference documentation — information-oriented technical description in the Diátaxis sense: austere, accurate, consistent facts about the machinery, consulted while working. Use whenever the user wants API docs, a configuration or parameter listing, CLI or command documentation, an options table, schema or data-model docs, error-code catalogs, environment-variable docs, or any "document what X is / what settings exist" request — even if they never say "reference". Also loaded by the diataxis router when the compass points to cognition + application: the reader needs *facts to consult* while *getting work done*. If the content is mostly why-and-context discussion, that's diataxis-explanation; if it directs the reader's actions step by step, that's diataxis-how-to. When the type is in doubt or mixed, consult the diataxis skill first.
