Show the interactive help card listing every slash command, its argument shape, and a one-line summary.
/help## Overview `/help` renders a text card listing every slash command registered in the shell's `COMMAND_CATALOG`, with the argument shape and one-line summary for each entry. It is the discoverable entry point into the slash surface: when the user is unsure which verb to use, typing `/help` gives the complete menu. ## Behavior - Runs fully offline. No control-plane round-trip, no auth required. - Output is grouped in the same order as the floating slash-menu overlay: Session, SQL analysis (offline), Docs (offline), Catalog, Compute node selection, Drill-in. - Accepts no arguments. Trailing tokens are ignored. - Also accessible by typing `:` at the start of the buffer, which opens the same menu as `/`. - To discover commands by fuzzy match without submitting, start typing `/` followed by a partial verb; the floating menu ranks by prefix then substring then subsequence and Tab completes to the top match.
