This is the way. Mine looks like `ctx: 0k / Fable 5 high`. When ctx ⪆ 200k, time to start a new session.

```statusline-command.sh

    #!/bin/sh
    input=$(cat)

    model=$(echo "$input" | jq -r '.model.display_name // empty' | sed 's/ context)/)/')
    effort=$(echo "$input" | jq -r '.effort.level // empty')
    used=$(echo "$input" | jq -r '.context_window.total_input_tokens // empty')
    out=""

    [ -n "$used" ] && out="ctx: $(( used / 1000 ))k"
    [ -n "$model" ] && out="$out / $model"
    [ -n "$effort" ] && out="$out $effort"

    # bright yellow + bold
    printf '\033[1;93m%s\033[0m' "$out"

```
