⚠️ 提交说明 / PR Notice

Important

  • 本描述由 AI 辅助整理,提交者已逐项审阅并在提交前确认;没有直接粘贴未经核验的输出。

📝 变更描述 / Description

Claude 兼容接口(包括 Kimi Coding Plan)返回的 input_tokens 只表示未命中缓存的输入,不包含 cache read / cache write。因此,全量缓存命中时 input_tokens = 0 是合法结果,并不代表没有输入或计费遗漏。

新前端迁移后丢失了旧版对此语义的提示,并且在 prompt/output 都为 0 时隐藏 Token 明细,导致只有缓存 Token 的日志看起来像空数据。本 PR:

  • 统一桌面表格、详情弹窗和移动端的缓存 Token 归一化逻辑;
  • 保留仅包含 cache read / cache write 的日志展示;
  • Claude 语义下将输入标记为 Uncached Input Tokens,并恢复说明 tooltip;
  • 优先使用后端已归一化的 cache_write_tokens,兼容旧字段和 5m/1h 拆分字段;
  • 补充回归测试和 7 个语言文件。

本 PR 不修改后端计费逻辑,也不会把缓存 Token 合并到主输入 Token 数字中。

Walkthrough

The change adds shared token normalization for usage logs. Desktop, detail, and mobile views use the normalized breakdown. Claude cache semantics receive localized labels and tooltip text. Tests cover cached Claude and OpenAI-compatible usage.

Changes

Usage token breakdown

Layer / File(s) Summary
Token breakdown contract and normalization
web/src/features/usage-logs/types.ts, web/src/features/usage-logs/lib/format.ts
Adds UsageTokenBreakdown and getUsageTokenBreakdown. The helper normalizes token values, cache-write sources, and Claude semantics.
Usage-log token displays
web/src/features/usage-logs/components/columns/common-logs-columns.tsx, web/src/features/usage-logs/components/dialogs/details-dialog.tsx, web/src/features/usage-logs/components/usage-logs-mobile-card.tsx, web/src/i18n/locales/*.json
Updates table, detail, and mobile token displays to use the shared breakdown. Adds Claude accounting tooltip text and uncached-input labels in seven locales.
Token breakdown validation
web/src/features/usage-logs/lib/__tests__/token-usage.test.ts
Adds tests for cached Claude requests, cache-write normalization, image-only usage, and OpenAI-compatible usage.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 56fc4

This change clarifies and normalizes token usage display across usage-log views, but cache-write breakdowns can still disagree with their reported total and image-only usage can remain hidden. The impact is limited to inaccurate or missing UI details, so the change is mergeable with explicit owner awareness or follow-up.

A rabbit counts tokens in rows neat and bright,
Cache reads and writes now appear in plain sight.
Claude labels hop into place,
Tests guard each counting case,
Shared numbers thump with delight.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep the cache-write breakdown consistent with the resolved total.

When cache_write_tokens is present and differs from the 5m/1h split-field sum, the formatter reports the normalized total but still returns the raw split values. The details view then renders only those split rows, so the displayed breakdown can undercount the total—for example, showing 20 + 30 against a reported total of 80.

Either clear the split fields when the normalized total wins so the unsplit row is rendered, or display the remaining difference explicitly. The displayed cache-write rows should always sum to tokenUsage.cacheWriteTokens.

150-154: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include image-only usage in hasTokens.

When other.image is truthy and other.image_output is positive while all prompt, completion, and cache counts are zero, this expression returns hasTokens: false. The downstream TokenBreakdown component returns before rendering its Image Tokens row.

Include positive other.image_output in hasTokens and add an image-only regression test.

Suggested fix
+  const hasImageTokens =
+    Boolean(other?.image) && tokenCount(other?.image_output) > 0
...
       cacheWriteTokens > 0 ||
+      hasImageTokens,
