Supersedes #23835, rebased onto current main.

Problem

On Usage, pick Past 24h, choose Hour under Breakdown, and switch from Cost to Tokens. The cards and chart switch to tokens, but the provider columns and Total still show dollar costs, and the last column still says "Tokens". The daily breakdown uses the same hardcoded cells, so it has the same bug.

Change

A small timeBreakdownMetric(metric) helper in usageBreakdown.ts picks the value formatter and the trailing column for the selected metric. In Tokens mode, provider cells and Total show token counts, and the last column becomes Cost. Cost mode is unchanged. The same table renders both hourly and daily rows, so both are fixed.

Scope and approval

This is a small, focused fix for an obvious bug, so it falls under the CONTRIBUTING.md exception. It wires the existing metric selector into the existing time table. It adds no setting, default, or capability. Web and desktop share this table. Server, contracts, and mobile are untouched.

Verification

  • usageBreakdown.test.ts covers day and hour periods through a Cost → Tokens → Cost round trip, including the trailing column label and value. It also checks that a provider with no activity in the period shows $0.00 / 0. These tests fail on the base commit because the helper does not exist there.
  • vp run check:changed upstream/main: format, lint, knip, typecheck (2 packages), and tests all pass. vp test run src/components/usage in apps/web: 32/32 pass. tsc -p apps/web/tsconfig.json --noEmit: 0 errors.
  • Manual check: ran vp run dev with an isolated --home-dir on Windows and opened the Usage modal at Past 24h with the Hour breakdown. Captures come from headless Chromium against the same dev server. Before uses the nightly UsagePage.tsx and after uses this branch. Usage data was refreshed between runs, so the totals differ slightly.
  • Not checked: mobile, which has a separate Usage UI and is not changed here.

Before: Tokens selected, table still shows cost

After: Tokens mode shows tokens, trailing column is Cost

Approvability

Verdict: Approved at c42b348

Macroscope's review found this PR approvable — This is a small, self-contained UI bug fix that makes the existing daily and hourly usage table honor the selected cost or token metric. It leaves cost-mode behavior unchanged and adds focused coverage for both resolutions.

Walkthrough

The time-breakdown table now formats provider values and period totals according to the selected cost or token metric. Its secondary-column label and value also use that metric. Tests cover daily totals, including providers with no period data.

Changes: Usage metric formatting

Layer / File(s) Summary
Metric formatters and coverage
apps/web/src/components/usage/usageBreakdown.ts, apps/web/src/components/usage/usageBreakdown.test.ts
Adds timeBreakdownMetric to select cost or token formatters and the complementary secondary label. Tests cover provider and total formatting, labels, and missing provider totals.
Time-breakdown table integration
apps/web/src/components/usage/UsagePage.tsx
Uses the selected metric descriptor for the secondary-column label, provider values, and period totals.

Change: Bug fix

Suggested reviewers: maria-rcks, t3dotgg, juliusmarminge

Merge Risk: Minimal · up to 17031

The Usage table now shows token counts in provider and Total columns when Tokens is selected, with cost shown in the trailing column. Cost mode is unchanged. The change is low-risk and mergeable.

Explanation

The title names the fix and the area it touches: the usage metric (Cost or Tokens) is now respected by the time breakdown table. The raw summary confirms the change adds timeBreakdownMetric so the time breakdown follows the selected metric. The title is specific and uses the conventional commit format.

Full details: Description check

Explanation

The description follows the repository template. It has Problem, Change, Scope, and Verification sections, and each is filled in with specific content. The Problem section gives reproduction steps and expected behavior. The Change section explains the helper and its effect on both hourly and daily rows. The Scope section explains why no issue link is provided and cites the CONTRIBUTING.md exception. Verification lists focused tests, repo checks, a manual Windows check, and what was not checked. Screenshots are included as the template requires for UI changes. The description does not link an issue for the bug, so a maintainer may still ask for one. The template asks for an issue link or a reason, and the reason is given, so this does not block the check.

Add a focused UsagePage render test for the time-breakdown table.

usageBreakdown.test.ts tests the helper directly and never renders UsagePage. Reverting a UsagePage formatter or label call site would therefore leave these tests passing while the table regressed. Test both Cost and Tokens modes, including provider, Total, trailing value, and trailing label.

Verified in a real dev environment

verified as-is at c1e52fac7ca65cce642ce20b0fe170f54aa1a058. no source changes or pushes.

  • reproduced on github/main (32ecd71726) in a separate worktree, then ran the exact pr head. installed each with vp i, used isolated state, and stopped main before starting the pr server.
  • drove the real web app with the repository's playwright and /usr/bin/google-chrome. created a project pointing to a real git repository and submitted codex gpt-6.1-sol turns through the composer and local proxy. no mock usage data.
  • matching before/after captures use the same two app-generated native codex transcripts: 65,239 processed tokens, displayed as 65.2K, and $0.07 estimated cost. copied those real transcripts to a task-only codex home to keep unrelated verification activity out of the comparison.
  • on main, both hour and day tables kept dollar values under codex and total with tokens selected. on the pr, both show 65.2K under codex and total, with $0.07 under the complementary cost column.
  • exercised cost → tokens → cost for both resolutions. checked model breakdown and refresh. a further real turn on the pr returned Heading: usage verification and 4 + 4 = 8 in chat. refresh then showed 3 sessions / 92,095 tokens (92.1K); the hourly table and metric round trip still matched. also checked the table at 1024px in dark appearance.
  • blacksmith: vp run check:changed passed against the pr base (36d4d711b79c): format, lint, knip, typechecks for two packages, and all four focused tests. the broader usage unit pass had 30 passing tests; the two existing usage-toggle browser tests also passed. git.cafe reports 8 successful checks, none pending or failing.

before, hourly tokens:

main: hourly tokens still displays dollar values

after, hourly tokens, matching data:

pr: hourly tokens displays token values and complementary cost

before, daily tokens:

after, daily tokens, matching data:

animated recording of both metric round trips, model breakdown and refresh. inspected this export and verified the original mp4 playback and seeking in t3's browser:

pr: daily and hourly metric round trips with model breakdown and refresh

Not verified

native electron, ios/android, macos/windows, other providers, and relay/tunnel connections were not exercised on this linux vm. desktop shares the changed web table; mobile is separate and unchanged. codex limits were unavailable through this proxy (JSON-RPC -32600 on main); this pr changes the cost/tokens time table, not limits.
