feat(cursor): add token cost report with Cursor-metered total#1745EClinick wants to merge 19 commits into
Conversation
Cursor previously surfaced only status/quota, not per-model token cost. Add a cost report sourced from Cursor's cookie-authenticated dashboard API, reusing the existing Cursor session resolution. Core: - CursorUsageEventsFetcher pages get-filtered-usage-events, dedupes, and shapes events into an API-rate per-day/per-model report plus a Cursor-metered window total (sum of chargedCents). One fetch backs both numbers so they always cover the same window. - CursorStatusProbe.resolveSession generalizes the auth path so status and cost share one session-resolution flow; fetchCostReport runs on it. - CostUsageFetcher gains a macOS-only Cursor branch and a fetchAllHistory option (all-time window plus "All time" label when set). - Enable Cursor tokenCost capability and add a Cursor cost-estimate hint. CLI: - codexbar cost --provider cursor with --days and a new --all flag. - Text adds a "Cursor-metered" window line; JSON adds meteredCostUSD. App: - Menu cost card shows the Cursor-metered line; Preferences gains a global "Fetch full Cursor cost history" toggle wired through the settings store and the UsageStore refresh scope. Tests: - CursorUsageEventsFetcher pagination/dedupe/metered-cents and daily report mapping; CursorStatusProbe cost-report path.

Security Review detailsBest possible solution: Land only after the owner selects the Cursor dashboard cost contract, the branch matches that opt-in/source wording, and the PR body has refreshed redacted packaged CLI and menu proof for the final behavior. Do we have a high-confidence way to reproduce the issue? Not applicable as a bug reproduction: this is a feature PR. Source inspection confirms current main lacks Cursor cost support and the branch adds the new behavior. Is this the best way to solve the issue? Unclear until the owner decision lands. The implementation path is strong after the cache/docs fixes, but the best merge shape depends on whether Cursor dashboard history needs a separate opt-in and exact privacy/source wording.

… compiling Adding meteredLine to TokenUsageSection without a default made the synthesized memberwise initializer require it at every call site, breaking existing callers and tests that predate the Cursor-metered line. Add an explicit initializer that defaults meteredLine to nil so those call sites keep compiling.
The Cursor cost fetch always auto-resolved cookies, ignoring the cookie-source setting the status path respects. Thread a cursorCookieHeaderOverride from UsageStore through CostUsageFetcher into the Cursor cost report: forward the manual header when the source is Manual, skip the fetch entirely when it is Off, and fall back to auto resolution otherwise. Include the cookie source in the cost scope signature so toggling re-fetches.
…ping totalUsageEventsCount used a strict Int decode, so a string-encoded count (the API serializes some numbers as strings) became nil and could short-circuit pagination. Route it through the lenient CursorEventNumber decoder like every other numeric field. Also fix the paginate/dedupe test whose third event timestamp crossed into the next UTC day: it expected one day-entry while the correct grouping produced two. Move it onto the same UTC day so it exercises single-day grouping and dedup as intended.

- Add Cursor to the inline cost-dashboard allowlist and key the Preferences cost-status line off supportsTokenCost so the Cursor card shows cost like Claude/Codex. - Drop the cursor-specific all-time history feature (the "Fetch full Cursor cost history" toggle, its settings plumbing, the CLI --all flag, the "All time" label, and the history-span sizing). Cursor now uses the shared "History window: N days" setting, so the inline chart draws legible windowed bars instead of the full account history. - Keep the Cursor-metered total, now scoped to the selected window.

@openclaw-mantis visual task: verify CodexBar shows Cursor token cost with a Cursor-metered line and dashboard-source copy using redacted Cursor account data. |
loadCursorTokenSnapshot now derives the session value from the current local day instead of the latest history entry, so a stale day is never labeled "Today" in the menu or CLI. This matches the Codex/Claude cost window behavior. Adds a focused test covering the stale-latest case.
tokenUsageHint had no Cursor case, so the shared menu/inline cost card fell back to the generic local-logs estimate copy for dashboard-derived Cursor data. Return the Cursor dashboard hint instead.
CLI `cost --provider cursor` now resolves the configured Cursor cookie source the same way the usage path does: it skips the fetch (with a notice) when cookies are Off and forwards the Manual header so the dashboard request uses the configured session instead of auto-resolving a different one. Also gates Cursor in costSupportedProviders to macOS, since supportsTokenSnapshot(.cursor) is macOS-only and the CLI otherwise advertised Cursor cost on platforms where it can only fail.

The local serve /cost route fetched Cursor cost unconditionally, so it ignored the configured cookie source. Apply the shared gating helpers: - skip Cursor when the cookie source is Off - forward the Manual cookie header so served data matches the session - report supported providers dynamically via costSupportedProviderNames() This closes the merge-gate finding that serve /cost bypassed the same policy already enforced by the cost command.

@steipete 🐐 how's this looking? |
Resolve conflicts in two files by combining both intents: - InlineUsageDashboardContent: keep Cursor in the cost-history provider list and adopt main's more specific tokenCostInlineDashboardEnabled gate. - PreferencesGeneralPane: keep main's cost-summary display-style picker and padded VStack wrapper, and add the Cursor cost status line. Keep `make check` green after the merge: - DRY UsageStore.refreshTokenUsage via a resetTokenState(for:resetFetchMarkers:) helper so the body stays under the function_body_length limit. - Scope line_length disables to the Cursor usage-event JSON fixtures, matching the existing MistralUsageParserTests convention.

Maintainer review against current The data path is substantially stronger than the older cost proposals: it reuses Cursor auth resolution, paginates and deduplicates events, preserves local-day “Today” semantics, and keeps API-rate estimates separate from Cursor-metered totals. Focused tests are green: I am holding the merge for the remaining product/auth decision and documentation gap. This adds an authenticated remote dashboard source to the app, CLI, and server, but Recommendation: approve as an opt-in Cursor dashboard cost source once the auth/privacy choice is explicit and docs/proof match the final UI. No merge from this review. |

Maintainer follow-up: pushed The fix closes the concrete CLI/server contract gap found during review: when Cursor cost is requested while the Cursor cookie source is Off, Exact-head proof:
Recommendation remains: keep this open rather than merge yet. The implementation is strong, but enabling authenticated Cursor dashboard access still needs the product/privacy decision, user-facing docs ( |

@steipete sorry for late response, here ya go |
Owner decision — product/privacy hold
Decision requested: Should CodexBar fetch detailed Cursor usage-event history through the existing cookie-authenticated dashboard session to calculate per-day/per-model cost estimates, or should Cursor remain limited to its summary usage/status data?
Tradeoff: The report makes otherwise hidden API-rate and Cursor-metered totals useful in the app and CLI. It also expands an authenticated dashboard integration into detailed event-history collection, depends on a private endpoint contract, and presents estimates that users may read as billing truth.
Recommendation: Do not land the current behavior yet. Prefer an explicit opt-in plus approved privacy/source wording before enabling this network-backed history fetch. If the owner accepts the existing-auth/no-new-setting model, the implementation below is prepared and exact-head CI is the remaining mechanical gate.
This PR is intentionally held for that owner decision; green CI does not make it merge-ready.
Summary
Adds a Cursor token-cost report to CodexBar, sourced from Cursor's cookie-authenticated dashboard API and reusing the existing Cursor session resolution (the same auth path as the status probe). Each usage event carries both a vendor list-price token cost (
tokenUsage.totalCents) and the amount Cursor's plan actually deducts (chargedCents), so a single fetch yields both an API-rate per-day/per-model breakdown and a "Cursor-metered" window total covering the exact same window.Core
CursorUsageEventsFetcher: pagesPOST /api/dashboard/get-filtered-usage-events, dedupes events on their natural key, and shapes them into aCostUsageDailyReport(API-rate) plus a metered window total (sum ofchargedCents). Lenient numeric decoding handles Cursor serializing some numbers as strings, and the CSRF-protected POST sends the requiredOriginheader.CursorStatusProbe: generalizedresolveSessionso status and cost share one session-resolution flow (manual cookie, cached cookie, browser cookies, stored session, Cursor.app fallback); addedfetchCostReporton top of it.CostUsageFetcher: macOS-only Cursor branch over a rollinghistoryDayswindow (like Codex/Claude), with the session line tied to the current local day.tokenCostcapability and added a Cursor-specific cost-estimate hint.CLI
codexbar cost --provider cursor, honoring--days(1…365).Cursor-metered: $X (window)line; JSON addsmeteredCostUSD. The unsupported-provider error lists supported providers dynamically.App (UI)
Cursor-meteredline alongside the API-rate estimate, the Cursor dashboard hint, and an inline windowed cost chart consistent with other providers.Live proof —
codexbar cost --provider cursorsource: "web"confirms the live dashboard fetch; the Cursor-metered total and the per-model breakdown are both present. (Real token counts/amounts, lightly trimmed.)Tests
CursorUsageEventsFetcherTests: pagination/dedupe, metered-cents summing (including nil-vs-zero), per-day/per-model mapping, and current-local-day session selection.CursorStatusProbeTests: cost-report path over the shared session resolution.Commands run
