Why

The Usage page records token cost, not the subscription windows people actually hit. Claude, Codex, and Grok each expose a 5-hour and/or weekly allowance, and some of those allowances are per model.

What

  • Settings → Usage → Plan usage, above the token ledger.
  • One row per signed-in Claude, Codex, and Grok account. Account totals show percent remaining for the 5-hour window and the weekly window, with reset time. A window the provider does not report is labeled as not reported. Grok's weekly credit pool does not invent a 5-hour bar.
  • By model shows percent used when the provider splits a window: Claude five_hour_<model> / seven_day_<model>, Codex named additional_rate_limits (and code review when present), Grok productUsage slices such as Grok Build. No estimated split.
  • GET /api/plan-usage uses the same admin gate as GET /api/usage. Access tokens are read from the CLI credential files the engines already use, sent only as request headers, and never returned or logged. Expired or missing tokens become "Sign in again" for that provider. Credential files are not refreshed or written.

Provenance

Checks

  • corepack pnpm exec vitest run server/plan-usage.test.ts — passed (1 file, 9 tests).
  • corepack pnpm exec oxlint --deny-warnings on the files this branch touches — passed (0 warnings, 0 errors).
  • Full pnpm test / pnpm typecheck / pnpm lint were not run locally; CI should run them.

No new dependencies. No enterprise/ changes. No release or publish-target changes.

Summary by CodeRabbit

  • New Features
    • Added a plan-usage card in Settings showing subscription allowances for Claude, Codex, and Grok, including remaining and used amounts, reset times, and available model or product breakdowns.
    • Added a manual refresh option and clear states for loading, unavailable usage, and errors.
    • Added automatic updates when a reported usage window resets.
    • Expanded Usage settings search terms to include quotas, remaining balance, weekly usage, five-hour windows, and model usage.

Settings → Usage shows the remaining 5-hour and weekly allowance for each signed-in Claude, Codex, and Grok account, and the percent used when a provider splits a window by model. Tokens stay on the server. A window the provider does not report is labeled as not reported, and no estimated split is invented.

📝 Walkthrough

Walkthrough

The pull request adds plan-usage retrieval and display for Claude, Codex, and Grok. It parses provider usage, supports credential lookup and caching, exposes reports through an API route, and displays them in the Usage settings section.

Changes

Provider plan usage

Layer / File(s) Summary
Usage parsing and account discovery
server/plan-usage.ts, server/plan-usage.test.ts
Parses provider usage into standard windows and additional allowances. Maps supported instances to plan accounts. Tests cover parsing and account discovery.
Credential, fetch, and cache flow
server/plan-usage.ts, server/plan-usage.test.ts
Adds asynchronous credential reads, Claude Keychain lookup, provider-fetch handling, and environment-aware cache identity. Tests cover credentials, provider responses, secret exclusion, and cache behavior.
API route and settings display
server/index.ts, src/components/PlanUsage.tsx, src/components/UsageSection.tsx, src/components/SettingsModal.tsx, src/locales/en.json
Adds the report API route and settings card. The card displays provider usage, errors, and reset timing. Adds related English labels and search keywords.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to dd956

The new usage view is restricted to administrators, but a custom Claude account can display usage obtained with a different account’s credential. A concurrent refresh can also leave an older report visible. These are account-attribution risks rather than evidence of token disclosure.

Retained concerns

  • Medium · security · inferred: When a custom Claude directory has no usable file or directory-specific Keychain credential, lookup can use the bare Keychain credential and label its usage as belonging to the custom account.
  • Low · reliability · inferred: An older fetch can finish after an explicit refresh and overwrite its newer cached report. If credentials changed under the same account descriptor, subsequent reads can briefly show usage from the earlier login.
Security review details

Security Blast Radius

  • inferred — The reachable audience is the existing admin-authorized request path, and the route reports across all configured provider instances. The identified credential-provenance effect is confined to accounts for which the custom Claude lookup reaches the bare Keychain fallback.

Security Findings and Attack Paths

  • inferred — If the bare Keychain service holds another login’s valid token, a custom-directory row without its own usable credential can obtain that login’s usage. The token itself is not returned by the report.

Trust Boundaries and Controls

  • observed — The shared request gate rejects sessions lacking admin scope before the route reads credentials. Missing, expired, or failed credential reads become sign-in error rows before provider dispatch.

Resilience and Maintainability Implications

  • inferred — For the same cache key, an older in-flight request can publish after a newer refresh. A changed credential under that descriptor can therefore leave the earlier login’s usage visible until another fetch replaces it.

Hardening Proposals

  • proposed — For a non-default Claude directory, require a credential tied to that directory—or an independently verified equivalent—rather than silently accepting the bare Keychain service.
  • proposed — Make cache publication conditional on the current request generation so an older fetch cannot replace a newer refresh for the same account set.

Read a macOS Keychain Claude login when the credentials file has no token. Only Opus, Sonnet, and Haiku are model rows. The reset label ticks and refreshes when a window ends.

Updated from the review.

  • Opus, Sonnet, and Haiku are the only Claude model rows. Other windows, including seven_day_oauth_apps, stay on an extra line.
  • If ~/.claude/.credentials.json has no usable token, a macOS login is read from the Keychain (read-only, Claude Code-credentials, with the config-dir suffix for a non-default account). The token is still not returned or logged.
  • The cache key includes the account environment, so a changed login directory is not served the previous report.
  • The reset countdown updates while Usage stays open, and a window that has already reset is refreshed once.

A custom config directory reads only its own Keychain item. If that item has no token, plan usage says to sign in again instead of showing the default account.

A custom Claude config directory now reads only its own Keychain item. If that item has no token, plan usage asks you to sign in again instead of showing the default account's usage under the custom name.
