Why ada
Good instructions make the missing detail visible, without making an ordinary task feel more complicated.
The missing detail
Two people can follow the same recipe and reach different results. A pan may be crowded, an ingredient wetter, or a portion quite different from the one the writer had in mind. The instruction is not necessarily wrong; it may simply leave too much unsaid for the reader's situation.
That is the question behind ada's approach: which detail would make the next decision clearer? Sometimes it is a definition. Sometimes it is a comparison or a small calculation. Often it is a sentence placed before the step it changes.
Connected reading
A useful guide should not strand the reader at the end of an answer. Meal planning leads naturally to shopping quantities; shopping quantities lead to scaling and the meaning of recipe yield. The links between those questions matter as much as the individual pages.
The same principle connects other subjects without pretending they are interchangeable. A food label, a supplement claim and a research abstract each need their own context. Familiar navigation can help a reader move between them, but the explanation must remain specific to the subject.
Room for judgement
ada is intended to support a reader's judgement, not replace it with a universal score. A source can be useful without answering every question. A tool can calculate correctly without knowing the household's circumstances. Making those limits visible gives the reader a better basis for choosing.
If a page leaves an important step unclear, point to that step through the contact page. A precise question can be more useful than a broad request for more information: it identifies the missing connection that another reader may need too.
