Prompt

Make me a Claude Code mod called token-weather: a live forecast of my context window, shown in the band above the prompt. What it should show, on one line: - A weather icon and word for how full the context window is: under 25% ☀ Clear (yellow), 25–49% ☁ Cloudy (cyan), 50–74% ☂ Showers (blue), 75–89% ☇ Storm (magenta), 90% and up ↯ Compact soon (red). - The percentage used, then the tokens used out of the window, like "134.4k / 200k". - A small chart of the last 12 turns, drawn with ▁▂▃▄▅▆▇█. - How much the last turn added, like "▲ +98.3k last turn". It should update after every turn.
