What's Wrong?

The TUI top-right header (clock HH:MM:SS + counter [X/Y]) is visually
intrusive and there's no way to hide it. Please add a settings.json key
(e.g. "tui.hideHeader": true) or env var (CLAUDE_CODE_HIDE_HEADER=1) to
disable it while preserving the custom statusLine at the bottom.
The interactive TUI always renders a header in the top-right of the
conversation area showing the current time (HH:MM:SS) and a counter
in the form [X/Y] (the second number grows with the conversation).
There is no documented way to hide this — no CLI flag, no settings.json
key, no environment variable.

What Should Happen?

Provide a way to hide the top-right header while keeping the custom
bottom statusLine intact. Suggested options (any one is enough):

• settings.json: { "tui": { "hideHeader": true } }
• env var: CLAUDE_CODE_HIDE_HEADER=1
• CLI flag: --no-header

Error Messages/Logs

Steps to Reproduce

1. Launch Claude Code in an interactive terminal session

(e.g. claude in WSL2 / zsh / tmux, version 2.1.145)

1. Start any conversation — send a few messages, run a few tool calls
2. Observe the top-right of the conversation area
3. A header appears showing HH:MM:SS [X/Y] in orange

(the X/Y counter grows as the conversation progresses, e.g. [0/19] → [55/99])

1. Try to hide it:

• Check claude --help → no flag found
• Check settings.json schema → no key controls this element
• grep CLAUDE_* env vars in the binary → none disables it
• Setting statusLine.command in settings.json customizes only the bottom bar

1. The header remains visible with no way to disable it
