Solutions

1. Remove or correct the unrecognized input; run the command with --help to list valid arguments/commands.

When it happens

Trigger: Triggered when nasiko.js rejects the current invocation: Unknown Nasiko <value> argument: <value>

Common situations: Occurs while running scripts/nasiko.js with invalid arguments, missing flags, or a failing external dependency; the guard at scripts/nasiko.js:49 aborts the command with this message.
