TUI
TUI
Start with meaning, then move to detail.
This lesson explains TUI as part of using Hermes and understanding its behavior. You will learn what it does, when it matters, and the smallest safe test that proves it works.
If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?
For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.
For advanced readers, inspect Launch, Why the TUI, Collapsible banner sections, then verify failure modes and version compatibility.
Start with installation if you have not run Hermes yet.
A clear outcome before you read.
- Understand TUI without assumed prior knowledge.
- Separate the source description from what still needs testing in your environment.
- Read the first command and identify its inputs and outputs before copying it.
Short definitions before the details.
- Session & memory
- A session holds conversation context, while memory keeps selected facts that should persist.
Launch the modern terminal UI for Hermes — mouse-friendly, rich overlays, and non-blocking input.

# Resume a specific session by ID or title

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.
