CLI — the kessel command-line client

The kessel binary is the line-oriented, JSON-capable client. It is the fastest path for humans, scripts, ops, and agents — meaningful exit codes (0 ok / 1 statement-or-connection error / 2 bad usage) mean you do not have to scrape text to detect success.

See the full reference in Usage guide (full) §2b. The kessel command-line client — interactive shell commands, --json mode, pipe a .sql file, --addr/--token remote auth.
