CLI Symbols Glossary

The Hermes terminal interfaces speak a compact visual language: dots, chevrons, braille spinners, and status glyphs. This page is the decoder ring. It covers the TUI (where most of these render) and notes the pieces shared with the Classic CLI.

:::note Skins can restyle some of these Glyphs marked themeable below are brand defaults — a skin can override them (for example tool_prefix and the prompt symbol). Everything else is fixed in the renderer. :::

Transcript symbols
