feat(usage): add a Usage tab with provider limits and usage history - #2225
This PR adds a Usage tab to Settings. It shows live provider limits and a usage history.
Provider limits
Two host services supply the limits: copilotQuota and providerQuotas. They cover GitHub Copilot, OpenRouter, DeepSeek, Moonshot, Kimi Code, z.ai, MiniMax, NanoGPT, and OpenCode Go.
The payload parsers are pure functions with unit tests.
A key goes only to the default host of its own provider. A profile with a custom base URL shows "not checked". A profile on the default host is preferred over a gateway profile.
Only successful results are cached (60 seconds), per provider and per key. A failed refresh removes the old entry. Callers that ask for the same key share one request.
The webview sends a request id and cancels on unmount. The host aborts the fetches when the last waiting caller leaves, and the webview ignores an answer for an older request.
Copilot uses the GitHub session that VS Code already holds. It never prompts. Unknown usage shows "Usage not reported", not "0% used".
Keys stay in the extension host. The webview gets display-ready rows only.
Usage history
The history comes from local task history. The host records per-model usage (usageByModel) in task metadata, so a later change of the active profile does not relabel old requests.
Filters: Today, 7 days, 30 days, All time, and a workspace filter. A daily chart, breakdowns by provider, model, and mode, and CSV export.
Unpriced providers show tokens and "no price", not $0.00.
The chart steps by calendar day, so it is correct across a daylight-saving change. The view and the export share one "now" that rolls over at local midnight.
CSV cells that start with =, +, -, @, tab, or carriage return get a leading apostrophe.
Review notes
The Copilot quota endpoint (copilot_internal/user) is not a public API. A failure shows a quiet status row.
This PR adds no setting, so it does not touch updateSettings.
Mutation gate:mutation-diff reports 654 changed executable lines in the extension and 749 in the webview (limit 500). Most of it is providerQuotas.ts (467), UsageSettings.tsx (394), and usage.ts (181). The parsers and the view model are pure code with their own tests. I ask a maintainer for a one-time exclusion for this PR.
Test Procedure
pnpm check-types passes in webview-ui, src, and packages/types.
Webview tests pass (178 files, 2283 tests). Extension tests for the language models, the webview handler, and task persistence pass (53 files, 1097 tests).
Playwright snapshots cover the populated, degraded, and empty states in four themes.
The DST tests run in America/New_York and assert that the fixture crosses a clock change.
Manual: open Settings > Usage. Check each state. Click Refresh. Close the tab while a request runs. Export a CSV and open it in a spreadsheet.

Summary
Summary by CodeRabbit
New Features
Added a Usage section in Settings with cost and token summaries, daily charts, task and provider/model breakdowns, and date-range and workspace filters.
Export filtered usage history to CSV or open tasks from usage breakdowns.
View quota and balance details for supported providers, including GitHub Copilot, with refresh controls and reset dates when available.
Usage history includes provider and model details when available, and shows token totals when costs are unavailable.
Bug Fixes
Improved usage attribution, history persistence, date-range accuracy, CSV safety, and task-save reliability.
Failed pending-edit restores return edited content and images to the chat box.
Oversized usage exports are rejected with guidance to choose a shorter range.
Localization
Added Usage settings and checkpoint recovery translations across supported languages.
This PR adds a Usage settings tab with task-history summaries, provider quota displays, and CSV export. It adds per-model usage persistence and quota request handling. It also changes checkpoint restoration to track conversation rewind and task restart outcomes.
Changes: Usage reporting
Layer / File(s)
Summary
Usage attribution and persistence packages/types/src/history.ts, src/core/task-persistence/*, src/core/task/Task.ts, src/core/task/taskSaveQueue.ts
History items now include optional per-provider/model usage totals. Task request records track their provider, model, and serving protocol. Message writes and metadata updates use separate task-keyed queues, and persistence can explicitly clear usage breakdowns.
Quota contracts and retrieval packages/types/src/providers/vscode-llm.ts, packages/types/src/vscode-extension-host.ts, src/services/language-models/*, src/core/config/ProviderSettingsManager.ts
Quota message types and data structures are added. Services parse provider quota responses, load profiles with abort and timeout handling, and cache successful results.
Usage view, host messaging, and export src/core/webview/*, src/integrations/misc/export-usage-csv.ts, webview-ui/src/components/settings/*
The Settings UI adds Usage. It displays task-history summaries and provider quotas. Host messages support quota requests, cancellation, and CSV export. Export processing validates and neutralizes CSV before writing.
Usage calculations provide date and workspace filtering, aggregation, and CSV rows. Locale entries, gallery stories, and tests cover usage, quota display, export, and persistence behavior.
Checkpoint recovery
Layer / File(s)
Summary
Recovery errors and localized messages src/core/checkpoints/ConversationRewindError.ts, src/i18n/locales/*/common.json, src/core/checkpoints/__tests__/*
New error types distinguish rewind, partial rewind, and task restart failures. Locale messages describe checkpoint recovery outcomes.
Checkpoint restoration now rewinds conversation state and verifies task restart. Webview handlers report failures and return pending edits when the task did not restart and the pending edit still belongs to the restore operation.

Explanation
[#2215] The PR adds the Usage settings tab, quota display and refresh, and local task-history summaries with date and workspace filters, daily chart, provider/model breakdowns, and filtered CSV export. The reported implementation keeps provider credentials in the host, checks provider hosts and custom URLs, uses the existing GitHub session without prompting, cancels quota requests, and shows unpriced usage as tokens rather than $0.00. Per-model task metadata supports history attribution. The PR includes translations and automated coverage for these features.
Full details: Security Boundaries
Explanation
No concrete security-boundary failure was found in the changed paths. Quota requests filter profiles through the organization allowlist and use fixed provider URLs. CSV export validates and neutralizes the received text before writing it.
Full details: Out of Scope Changes check
Explanation
src/core/checkpoints/index.ts, src/core/checkpoints/ConversationRewindError.ts, and src/core/webview/checkpointRestoreHandler.ts change checkpoint restore, conversation rewind, task restart, and pending-edit recovery. The related checkpoint tests and checkpoint recovery translations also do not implement Usage settings or usage history [#2215].
Resolution
Move the checkpoint restore, rewind, task-restart, pending-edit recovery changes, their related tests, and checkpoint-specific translations to a separate PR. Keep usage-export translations and changes that support usage history.
Full details: Persistence Integrity
Explanation
The changed persistence path can lose usage attribution. In Task.ts:1913-1919, message and metadata writes use separate, host-local queues. If host A writes messages without usage, host B then writes usage and its metadata, and A writes its metadata last, the explicit clear in taskStoreConcurrency.ts:23-30 removes B’s usageByModel. The Usage view then treats that usage as unrecorded. Also, Task.ts:1948-1981 logs a metadata failure but reports the save as successful. If the last metadata write fails, the new usage breakdown can remain stale without a later save.
Resolution
Coordinate message and metadata writes across hosts, or use durable revisions to reject or recompute stale metadata. Report metadata partial failures and provide durable retry or recovery.
Full details: Regression Evidence
Explanation
Delete-after-abort recovery still lacks coverage of the real persistence and restart path. The PR moves restart responsibility to checkpointRestore and removes the handler’s save and rehydration. Task.persistence.spec.ts:3047–3081 uses mocked persistence and cancelTask; the handler test also mocks checkpointRestore and task creation. Neither test verifies what the real restarted task loads.
Resolution
Add a focused delete-after-abort test with real persistence and the real restart path. Verify that restore succeeds and the restarted task loads both rewound histories.
Full details: Lifecycle Resource Cleanup
Explanation
Two cancellation paths still retain or duplicate work: - ProviderSettingsManager.ts:134-180,783-810 leaves each cancelled caller's mapping callback attached to the batch promise. Repeated requests during a hanging secret read also start separate load calls against that read. If it completes, those calls parse the profiles and cancelled callers still clone and map them. - copilotQuota.ts:71-91,156-163,210-223 abandons but cannot cancel a pending getSession call. After cancellation or timeout, a later request can start another lookup while the first remains pending. The Usage tab cancels requests on refresh or close, and profile reads also have a 10-second deadline. Repeated requests during a hanging read or session lookup can therefore accumulate callbacks or duplicate work.
Resolution
Use detachable profile-read subscriptions and share the complete pending load while preserving write ordering. Share pending Copilot session lookups across cancelled and new requests. Add regression tests for hanging reads and session lookups, cancellation, and recovery with a live caller.

Why one PR. The Usage tab is one feature. The limits, the history, and the per-model usage record share types (ProviderQuota, usageByModel). A split leaves a half-working tab between merges. I already split the larger first PR (#2216) into three: time/date (#2223), fonts (#2224), and this one. The other two are under the limit.
Why the size is mostly parsers.providerQuotas.ts is the payload parsers for nine providers. They are pure functions of a JSON payload. usage.ts is a pure view model. Both have their own specs, including edge cases, DST, and CSV safety. The code that touches the network is small.
What I ask for. An exclusion for this PR only, or a one-time limit bump for the two packages.
If you prefer a split. I can cut it as: (1) the extension quota services and the message, (2) the history view model and the Usage tab. That makes the second PR depend on the first.

Inline comments:
Review comments at @src/core/task-persistence/usageByModel.ts:
- Around line 42-45: Update summarizeUsageByModel to reconcile per-model costs
with item.totalCost by assigning any meaningful remaining cost to the existing
unrecorded provider and model rows. Add the remainder without calling addTo, so
tasks with recorded usage do not gain extra unrecorded task counts, and ignore
negligible floating-point residue to avoid creating spurious priced rows.
Review comments at @src/core/task/Task.ts:
- Around line 3940-3941: Update updateApiReqMsg to record the resolved model ID,
using cachedStreamingModel.id when available and otherwise preserving
existingData.modelId; leave the initial api_req_started write unchanged.
Review comments at @src/core/webview/webviewMessageHandler.ts:
- Around line 134-135: Update pendingProviderQuotaRequests and the
requestProviderQuotas/cancelProviderQuotas handlers to track controllers by
ClineProvider as well as request ID, so canceling one provider’s request cannot
abort or delete another provider’s request with the same ID; only remove an
entry if it still refers to that request’s controller. Add a handler test using
two provider instances with the same request ID to verify their requests remain
isolated.
Review comments at @src/services/language-models/copilotQuota.ts:
- Around line 114-117: Update the Copilot quota cache flow so failed refreshes
do not retain stale successes and cached results are reused only for the GitHub
token that produced them. In the cache and fetch logic around getGitHubToken and
parseCopilotQuota, clear the cache on missing tokens, failed responses, and
caught errors; store the token with successful results and check it before
reusing a cached result. Preserve the existing in-flight request behavior and
add a test in copilotQuota.spec.ts covering a forced refresh failure after a
cached success.
Review comments at @src/services/language-models/providerQuotas.ts:
- Around line 393-401: Update the Kimi Code credentials callback to provide
kimiCodeApiKey only when kimiCodeAuthMethod is "api-key"; return no API key for
OAuth profiles, even if a stale key remains saved.
Review comments at @webview-ui/src/components/settings/ProviderLimits.tsx:
- Line 70: Update the empty-quotas handling in ProviderLimits so an empty
response does not hide the Refresh action; retain a way to retry quota loading
while preserving the existing display for connected providers.
- Line 44: Update the request ID generation around counter.current so IDs remain
unique across ProviderLimits component mounts; use a stable shared counter or
another unique-ID source instead of a counter reset on each mount, while
preserving the provider-quotas prefix.
Review comments at @webview-ui/src/components/settings/UsageSettings.tsx:
- Line 312: Update the mode breakdown mapping to use the full label from
bucketRow(m) instead of splitting it at “ · ”, preserving the “no price”
distinction for unpriced usage.
Review comments at @webview-ui/src/utils/usage.ts:
- Around line 261-270: Update the cacheHitRate calculation in the usage result
to use tokensIn as the denominator, since it already includes cache reads, and
cap the ratio at 1 while retaining the zero-input fallback. Update the
usage.spec.ts fixture and expected hit rate to use a tokensIn/cacheReads pair
consistent with that definition.

## Visual Tests (Playwright Story Gallery)
### When a UI change needs a snapshot
Skip a visual test when the change is behavior-only (state transitions, handler wiring, validation) — those belong in Vitest. Visual tests are for what JSDOM cannot verify.
[warning] 61-61: This synchronous effect update causes an extra render: Calling setState synchronously within an effect can trigger cascading renders. Prefer deriving or initializing the value before render. If the effect must read a browser API after mount, treat this as advisory or suppress it with // react-doctor-disable-next-line react-hooks-js/set-state-in-effect.
Effects are intended to synchronize state between React and external systems such as manually updating the DOM, state management libraries, or other platform APIs. In general, the body of an effect should do one or both of the following:
Update external systems with the latest state from React.
Subscribe for updates from some external system, calling setState in a callback function when external state changes.
⚠️Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Move the request-ID increment out of the component body so React Compiler can optimize it.
React Doctor reports that ++quotaRequestCounter on Line 48 is an update expression on a module-level variable. The compiler does not support it and skips memoization for ProviderLimits. The behavior is correct, and the module-level counter must stay. Wrap the increment in a module-scope helper.
Proposed fix
let quotaRequestCounter = 0
+const nextQuotaRequestId = () => `provider-quotas-${++quotaRequestCounter}`

121-130: Stale Copilot quota can be served after sign-out or account switch.
A previous review already raised this point, and the thread is still open. getGitHubCopilotQuota returns a cached success at Line 91, before getGitHubToken() runs at Line 96. After a sign-out or account switch, a normal call within 60 seconds returns the previous account's quota. The new failure-clearing code does not run on this path, because no fetch happens. Invalidate the cache on session change, or store the token with the cached entry and compare it before reuse. Add a regression test that caches a result, changes the session, and makes a normal call within the TTL.
No custom-base-URL fields exist for these providers.
The four provider schemas expose API keys and provider-specific settings, but no base-URL setting. The requested ownHost change and custom-gateway test do not apply.

reject or recompute stale metadata. Report metadata partial failures and provide
durable retry or recovery.
- Lifecycle Resource Cleanup:
Remove cancelled reads from the queue without changing write ordering. Bound or
reuse abandoned active storage reads so refreshes cannot accumulate them. Add
real-manager regression tests for both cases.

### When a UI change needs a snapshot
If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.

### Authoring rules
- Keep behavioral assertions in Vitest. A `*.visual.tsx` test should establish a deterministic state and make a focused screenshot assertion.
Status of the failed pre-merge checks against the latest head:
Linked Issues (locales): usage_export_too_large is in all 18 common.json files (added together with the export error in db67a63cb), and locale-bundles.spec.ts pins the key in every locale. The summary that the check read lists only some locales.
Security Boundaries: the quota handler now logs a fixed text ([requestProviderQuotas] Failed to load provider limits) and nothing of the error. Regression tests use a real ProviderSettingsManager over malformed profile JSON that holds an API key, and a storage error whose message holds one: the key appears in no log call (mutation-checked).
Regression Evidence: a new delete-after-abort test runs the real rewind and the real Task.say of an aborted task through the real persistence queues, with a disk that the saves write and the restart reads: what the restarted task loads is both histories cut at the checkpoint ([1, 2] on both sides); a mutation of the rewind fails it.
Lifecycle Resource Cleanup: the reads that wait for the same turn are now one batch (one place in line, one load, an answer for each caller), a batch that every caller has left is reused by the next read instead of adding another, and a batch nobody waits for at its turn reads nothing. A storage read that was given up on is joined by the reads that follow, until a write has been made, so repeated refreshes start one hanging read in total. Real-manager tests: 10 refreshes behind a permanently hanging read call secrets.get once; 50 cancelled reads behind an operation that never settles use one place in line and never load; one load answers every caller of a batch. Four mutations each fail a test.
Persistence Integrity (cross-host revisions, and a durable retry for a failed metadata write): unchanged: it needs a durable revision shared by extension hosts, a design decision for the maintainers; not part of this PR.
Codecov: tests for the non-Error branches of the partly-rewound message and the put-back.

Inline comments:
Review comments at @src/core/checkpoints/index.ts:
- Around line 270-290: Update the rewind failure handling in checkpointRestore
so a failure of both the API-history write and UI-message put-back is
distinguished from an ordinary rewind failure. Reconcile the two histories
before calling startTaskAgain; if reconciliation fails, return the pending edit
to the user and do not restart with inconsistent history. Reuse the existing
reconciliation and pending-edit mechanisms rather than assuming new APIs.
Review comments at @src/core/config/ProviderSettingsManager.ts:
- Around line 136-140: Update ProviderSettingsManager.lock so enqueueing an
operation ends sharing of any unstarted readBatch; subsequent signal reads must
create a batch ordered after that operation rather than joining the earlier
batch created by newReadBatch. Add a regression test that holds the lock, issues
a signal read, calls saveConfig, then issues another signal read and verifies
the latter returns the saved profile.
Review comments at @src/core/task/Task.ts:
- Around line 4094-4115: Capture the api_req_started placeholder by identity
when it is created in the request flow around this.say; remove the findLast
fallback so an older request can never be selected. Ensure downstream membership
checks and send logic use only that captured placeholder, and stop the turn if
it was deleted.
Review comments at @src/i18n/locales/zh-TW/common.json:
- Around line 21-23: Update the zh-TW strings for checkpoint_rewind_failed and
checkpoint_rewind_restart_failed to use 存檔點 consistently with the adjacent
checkpoint messages, preserving the existing meaning and interpolation
placeholders.
Review comments at @webview-ui/src/utils/__tests__/usage.dst.spec.ts:
- Around line 142-148: Update the usage range test around `written` to assert
the complete ordered CSV row list for each range, including excluded boundary
tasks. In the “counts the same tasks in the totals as in the export, for today”
test, compare the number of rows from `written("today")` with
`summary.taskCount` to verify export parity.
Review comments at @webview-ui/src/utils/usage.ts:
- Line 267: Guard token fields in usage aggregation so missing, non-numeric, or
non-finite values count as zero. Update the entry total calculation and the
primaryUsage selection logic to use the same normalization, preventing invalid
values from affecting provider/model totals or entry selection.

Failed pre-merge checks:
- Regression Evidence:
Add a focused delete-after-abort test with real persistence and the real restart
path. Verify that the restore succeeds and that the restarted task loads both
rewound histories.
- Persistence Integrity:
Coordinate message and metadata writes across hosts, or use durable revisions to
reject or recompute stale metadata. Report metadata partial failures and provide
durable retry or recovery.
- Lifecycle Resource Cleanup:
Use detachable caller subscriptions so cancellation removes each caller and
prevents its mapping work. Share the complete pending load, not only the storage
promise, so repeated cancelled batches do not add continuations to a hanging
read. Preserve write ordering and add real-manager regression tests for both
hanging paths and for recovery with a live caller.

## Unit & State Tests (Vitest + JSDOM)
- Prefer local `webview-ui` tests for React/webview behavior. If a change is about component rendering, local state, hooks, form dirty-state, validation, or prop wiring inside the webview, add or update Vitest coverage under `webview-ui/src/**/__tests__` instead of reaching for `apps/vscode-e2e`.

Preserve messages added while rollback is pending.
messagesBefore is captured before the awaited rewind and API-history save. If the active task adds a message after the cut, an API-history storage failure makes this full-list overwrite replace the newer message with the old snapshot. Reconcile the rollback with messages added since the snapshot, or prevent concurrent task writes before starting the rewind. Add a test that appends a message during the pending save.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Test name and comments do not match the exercised path.
The test stubs say and never adds a placeholder. Line 4031 uses a no-op say, so requestMessage is undefined before any wait. The request then fails at the post-wait check in recursivelyMakeClineRequests. This covers "placeholder absent after say returns". It does not cover "deleted while being written", as the title says.
Line 4032 says a deletion removes the placeholder during preparation. Line 4033 only calls vi.mocked(getEnvironmentDetails).mockClear(), and no deletion occurs. The comment is stale.
The behavior is covered, but the title and comments mislead. A change that moves the check would still pass this test.
Rename the test to say that no placeholder is added by say.
Remove the stale comment on Line 4032.

Learning: In `src/core/task/Task.ts`, `Task.recursivelyMakeClineRequests()` catches errors in its outer request loop and returns `true` to signal that the parent loop should end the task. In `src/core/task/__tests__/Task.spec.ts`, a cancellation regression test should expect that request promise to resolve to `true`, not reject.

Test removal after the first placeholder check.
The second guard stops the request by returning true; it does not propagate the error. Add a Task-level test that removes the placeholder during safeEnsureModelFetched and asserts that the loop returns true, sends no request, and leaves the older message unchanged. The existing deletion tests only exercise the first guard.

For persisted settings, verify the complete schema/storage/runtime/webview round trip, shared default semantics, and focused true plus false/unset tests.
Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.
Notes on the failed pre-merge checks (verified against the current head; no code change for these):
Out of Scope Changes (checkpoint restore, rewind, restart, pending-edit recovery): these changes are there because Usage depends on them: a rewind or a delete removes requests whose usage the Usage tab counts, and the note that reports the deleted requests (api_req_deleted) carries that usage, so the rewind, its persistence and the restart have to keep the per-model history consistent. Moving them to a separate PR would leave this one with a history that a restore can silently make wrong. If the maintainers want the split anyway, it is a restructuring of the branch that I would do on their word, not on my own.
Regression Evidence: a delete-after-abort test exists (Task.persistence.spec.ts): the real Task.say of an aborted task, the real rewind and MessageManager, the real persistence queues over a disk that the saves write and the restart reads, and a mutation of the rewind fails it. A test that uses the file system and a whole provider and task for the restart would need a harness that does not exist in this code base; I would rather not build one for this PR.
Persistence Integrity (cross-host writes): unchanged from the earlier notes. It needs a durable revision shared by the extension hosts, which is a design decision for the maintainers, not part of this PR.
Lifecycle Resource Cleanup (profile reads, Copilot session lookups): the profile reads already share one place in line and one load, and an abandoned storage read is joined by the following reads; what is left is the case of a session lookup of the authentication provider that never settles, repeated across refreshes. That is a stalled external service on top of a request that is already bounded by its deadline and cancelled by the caller, so I am not adding another sharing layer for it here.

untilAborted here is a copy of until in providerQuotas.ts:839, and the copy skips the already-aborted check. Could both files share one helper in quotaUtils.ts?

This escape is a second formula sanitizer, with different character classes from neutralizeCsvFormulas in export-usage-csv.ts:44. Would a test that runs usageToCsv output through neutralizeCsvFormulas catch drift between them?
I close this PR because it is too large to review safely. It changes about 15,000 lines in 104 files, and the description says it is one feature. It holds five separate units of work.
Units 1, 2, and 3 do not depend on the Usage tab. Open them first. Before unit 5, move the shared abort and single-flight helper into quotaUtils.ts. Unit 4 can then follow.
The inline comments in the review apply to units 4 and 5. Link each new PR to #2215.

Description
This PR adds a Usage tab to Settings. It shows live provider limits and a usage history.
Provider limits
copilotQuotaandproviderQuotas. They cover GitHub Copilot, OpenRouter, DeepSeek, Moonshot, Kimi Code, z.ai, MiniMax, NanoGPT, and OpenCode Go.Usage history

copilot_internal/user) is not a public API. A failure shows a quiet status row.updateSettings.mutation-diffreports 654 changed executable lines in the extension and 749 in the webview (limit 500). Most of it isproviderQuotas.ts(467),UsageSettings.tsx(394), andusage.ts(181). The parsers and the view model are pure code with their own tests. I ask a maintainer for a one-time exclusion for this PR.Test Procedure
