q

Use when writing, editing, reviewing, or debugging q/kdb+ code (.q files), querying kdb+ tables, translating Python to q, running q from shell, doing time-series analysis, or optimizing q performance. Also use when encountering q errors ('assign, 'rank, 'type), reserved-word conflicts, right-to-left evaluation bugs, or atom/vector type mismatches. Trigger whenever the user is working with .q files, kdb+ tables, or qsql queries even if they don't explicitly ask for q help.
