Short answers for the first problems people hit.
clai / cliai: command not found
Install succeeded but the shell cannot find the binary. Add ~/.local/bin to PATH (or log out and back in), then open a new terminal.
Difference between clai and cliai
Same program; clai is the short name, cliai is the full binary name.
Why use quotes around the task?
The shell splits on spaces. Wrapping the whole task in quotes keeps it as one argument.
What does cliai update do?
It is reserved for automatic upgrades. Today it only reports that updating from the tool is not available yet; use Download or re-run the install script for a new version.
What is cliai stats?
It shows usage figures tied to your account (quota-style signals). Do not share personal stats links with people you do not trust.
Change the UI language
Set CLIAI_LANG (for example en, ru) or rely on normal LANG / LC_* locale variables.
