CLI (command line interface)
A CLI, or command line interface, is a program controlled by typing text commands instead of clicking buttons.
What it tells you about a developer
CLI work signals comfort with automation and with server and infrastructure environments. Many developer tools ship as a CLI, so a developer who has built one has designed for other developers.
CLI stands for command line interface. It is the oldest style of computer interface, predating the mouse, and it stayed in constant use because typing a command is often faster and easier to automate than clicking through menus. A coding agent is often built as a CLI, meaning a developer runs it by typing a command in a terminal and the agent works from there. A developer comfortable with CLIs is comfortable working without a visual interface, which is common in server and infrastructure work.
