request: Pass available width(s) to statusLine command hook

heh. Claude Code (Opus 4.1) hopes that Claude Code will someday add it to the JSON. It imagined this optimistic vision of the future just based on me telling it that tput cols did not work. (and this happened before I submitted this /bug report in a different instance of Claude Code.)

I wrote:

tput cols always says 80 inside Claude Code

Claude Code worked then reported back:

````
[...]
● Updated the script to handle the tput cols limitation. It now:

1. First checks if Claude Code provides terminal_width in the JSON (in case they add it in the future)
2. Falls back to a reasonable default of 120 columns if not provided

I've got a bit of a 'hack' for this that works on POSIX compliant systems over in ccstatusline.ts that grabs it from the parent process using stty. The bigger issue is even with the correct width, rendering can be thrown off by their IDE integration features (showing filename, total lines selected) or their auto-compact message. One workaround is subtract 40 off of it, but then it leaves things looking weird.

I added a hacky workaround to that in ccstatusline that keeps it fully right aligned until the context percentage reaches the auto-compact threshold, but I still don't really like the solution. You can give it a try usingnpx ccstatusline and grab the code if it works for your needs. I've requested via /bug that they add the usable terminal width to the JSON. So fingers crossed.

I don't think this is a duplicate of those issues.

• inheriting a variable is no longer sufficient to calculate the available width(s) on the status lines
• this request is not related to any crashing
• this is not related the Bash tool

seems like the issue is that no env variables are passed to CC. Maybe it's for security reason, but it makes status line less useful

Adding another data point: experiencing this on Windows 11 with both PowerShell and Git Bash.

Environment:

• Claude Code 2.0.73
• Windows 11
• Both PowerShell 7 and Git Bash (MINGW64)
• Window snapped to half-screen width

Findings:

• tput cols returns 80 regardless of actual window size
• stty size fails entirely on Windows
• Node.js process.stdout.columns returns undefined
• $COLUMNS environment variable is empty/unset

Impact: Text rendering corruption - characters missing, lines truncating mid-word. Makes Claude Code difficult to use on Windows with any terminal wider than 80 columns.

This is blocking productive use. Would love to see a fix or at minimum a config option to manually set terminal width.
