COMMAND
COMMAND INFO [command-name ...]
COMMAND returns descriptors for every keyword in Goblin Core's perfect-hash dispatch table. COMMAND INFO returns one descriptor per requested name and a null entry for an unknown command. Descriptors use the Redis 7+ ten-field shape: name, arity, flags, legacy key positions, ACL categories, tips, key specs, and subcommands.
