When it fires
Fires on «document this», «adr», «changelog», «this README».
You do not pick this room from a menu. You write the work and the radar lights it if the turn belongs to it.

Docs
/// one of eleven · the rest off
A case
/docs-audit . classifies each page by Diátaxis mode, flags mixed modes and snippets that no longer run.
That is the kind of prompt that should light it without you typing the id. If the radar is often wrong in your repo, the fix is in the pack's triggers, not in memorising /domains every morning.
The sister
Border with Escritura (ES): Docs decides which question each page answers and in which mode; the sister watches that the Spanish on that page obeys the house rules.
Sister file: Escritura (ES). Both can be enabled at once. On a given turn only one context travels.
