What's a coding harness? Claude Code is a "harness" and not a TUI?

The fact that it's a tui isn't particularly relevant. It could be a gui or cli and provide very similar value.

Nearly all of its value is facilitating your interaction with the LLM, the tools it can use, and how it uses them.

If you run Claude Code with `-p --output-format json` it's no longer a TUI, but it's still a harness.
