Problem

Pi reported only Kimi even when other upstream CLI providers were authenticated on the same machine. Usage accounts whose credentials live in an external CLI's own store were invisible, so the usage panel showed partial data or nothing at all.

Solution

• Generic credential discovery scans known CLI credential locations, so new providers plug in without bespoke storage code.
• Per-provider readers turn each discovered credential into a reported account.
• usageAccounts is additive on the usage report; existing consumers are unchanged.
• Reset windows are reported separately from monetary usage, so rate-limit and credit accounts both render correctly.
• Unsupported or unreadable accounts are safely omitted instead of failing the whole report.

Validation

• vp run check:changed upstream/main: 99 passed / 2 skipped.
• Integrated mocked web fixture pass; no paid provider calls.

UI evidence

Before — no limits reported:

After — monetary-only pools:

After — popover monetary rows:

Walkthrough

The change adds Kimi Code and OpenRouter usage probes, carries provider usage accounts through Pi and OpenCode snapshots, and includes them in shared usage reporting. Web and mobile views display available monetary usage values, and the usage documentation describes provider reporting.

Changes: Provider Usage Accounts

Layer / File(s)	Summary
Usage contracts and upstream probes packages/contracts/src/providerUsageLimits.ts, packages/contracts/src/server.ts, packages/provider-core/src/server/{upstreamUsage,kimiUsage,openRouterUsage}*, packages/provider-core/package.json	Contracts add optional monetary usage and provider usage accounts. Shared credential discovery and Kimi Code and OpenRouter readers parse supported account usage, with tests covering parsing and request failures.
Driver probing and snapshot propagation packages/provider-core/src/server/snapshotProbe.ts, packages/provider-pi/src/server/driver.ts, packages/provider-opencode/src/server/driver.ts	Pi and OpenCode discover credentials and probe supported upstream accounts. Provider snapshots include the resulting usage accounts.
Shared usage-account reporting packages/shared/src/usageLimits.ts, packages/shared/src/usageLimits.test.ts	Shared account collection and usage-limit reports include supported provider accounts. Monetary values without rate-limit windows count as reported limits. Tests cover account inclusion, unsupported-account omission, and report fields.
Monetary usage display and documentation apps/mobile/src/features/usage/UsageLimitsSection.tsx, apps/web/src/components/usage/UsageLimitsPooled.tsx, docs/user/usage.md	Mobile and web views display available monetary usage values. The documentation describes supported provider usage reporting and the remaining transcript token and cost history.

Add a timeout to the OpenRouter probe.

httpClient.execute and response.json have no deadline. Effect.orElseSucceed handles only failures, not a stalled connection. readKimiCodeUsageAccount bounds its probe with Effect.timeout(PROBE_TIMEOUT), but this reader does not.

The Pi checkProvider yields upstreamUsageAccounts, and the OpenCode checkProvider waits for usageAccounts in Effect.all. A stalled OpenRouter request therefore blocks the provider status refresh for the whole driver. probeUpstreamUsage does not add a timeout either.

Apply the same bounded timeout and fold the result into failed.

usageAccounts never reach the pooled view for providers without usable native limits.

The new loop sits after this guard at Line 320, which is unchanged:

if (!provider.usageLimits || limitsNotice(provider.usageLimits) !== null) continue;

providersWithLimits now admits providers that have usageAccounts but no usable usageLimits. That case is common:

• The Pi driver sets only usageAccounts. It never sets usageLimits, so continue skips every Pi account.
• OpenCode without a Go key gets usageLimits with unavailable. limitsNotice is then non-null, so continue skips its OpenRouter and Kimi accounts.

collectProviderUsageLimits does not have this problem because its usage-account loop is separate. The new test passes only because its provider has native windows. The main feature (Pi and OpenCode upstream accounts on Usage → Limits) therefore does not render for these providers.

Gate only the native merge on the guard. Always iterate usageAccounts.

Proposed fix (also changes unchanged Lines 320-332)

-      if (!provider.usageLimits || limitsNotice(provider.usageLimits) !== null) continue;
-      merge(resolveKey(nativeReport(provider)) ?? `${environmentId}:${provider.instanceId}`, {
-        key: `${environmentId}:${provider.instanceId}`,
-        ...
-        limits: provider.usageLimits,
-      });
+      if (provider.usageLimits && limitsNotice(provider.usageLimits) === null) {
+        merge(resolveKey(nativeReport(provider)) ?? `${environmentId}:${provider.instanceId}`, {
+          key: `${environmentId}:${provider.instanceId}`,
+          ...
+          limits: provider.usageLimits,
+        });
+      }
       for (const account of provider.usageAccounts ?? []) {

Add a test case with a provider that has usageAccounts and no usageLimits, and one with usageLimits.unavailable.
