Prompter

The line you forgot, whispered from offstage

In theater, the prompter sits just offstage with the script and feeds the line to anyone who blanks mid-scene. Here, the script is the Cratis documentation and the stage is the community Discord - ask, and Prompter answers with citations, or says honestly that the docs don’t cover it.

Without Prompter, a question waits for a human in the right timezone who happens to know the answer - even when that answer sits in the documentation the whole time. With Prompter, the documentation answers first, in seconds, with links - and humans spend their energy on the questions that genuinely need them.

What it doesn’t do

It never answers from general knowledge, never interjects uninvited, and never pretends: when the documentation doesn’t cover a question, it says so and hands you back to the community - and that miss is logged as a signal for documentation worth writing.
