Review-only companion for kahme247#201. Same head and matching upstream base (45b346e), so the diff is identical. Keep this review base separate from main. Local verification: typecheck passes; lint has 0 errors and 11 existing warnings; 1,105 tests pass, 5 skipped; actual CLI-backed manual refresh/checkmark succeeds and provider report timestamps refresh. Manual refresh invalidates omp’s persisted cache, automatic polling remains unchanged.

Summary by CodeRabbit

  • New Features
    • Added a refresh button to the Provider Usage panel for fetching the latest usage limits. A successful refresh displays a confirmation.
  • Improvements
    • Manual refresh bypasses cached usage data. Automatic refresh continues on its existing schedule.
    • If a manual refresh fails or cannot invalidate cached data, the panel shows usage as unavailable rather than indicating success.

Reuse the workspace refresh control and success checkmark. Bypass the server usage cache only for manual refreshes while retaining the existing five-minute automatic polling schedule.
Keep background polling silent, preserve refresh queries on older browsers, and ensure manual refresh is not satisfied by a concurrent background fetch. Cover persisted caching and hook behavior with regression checks.

📝 Walkthrough

Walkthrough

The provider usage panel now supports manual refresh. The request bypasses omp-web’s usage cache, invalidates omp’s cached reports, and returns refresh success or failure to the sidebar. Automatic five-minute refresh remains unchanged.

Changes

Provider Usage Manual Refresh

Layer / File(s) Summary
API refresh and usage retrieval
app/api/provider-usage/route.ts, lib/provider-usage.ts, lib/provider-usage.test.mjs
The API passes refresh=true to usage retrieval when the query parameter matches exactly. Forced retrieval invalidates omp’s cached reports and bypasses the omp-web cache. A forced request waits for an ordinary in-flight request before starting. Tests check refreshed and cached values.
Hook and sidebar refresh control
components/AppShell-provider-usage.ts, components/ProviderUsageBar.tsx, components/AppShell-provider-usage.test.mjs, CHANGELOG.md
The hook exposes a refresh callback that reports success or failure and coordinates concurrent requests. The sidebar button is disabled while loading and shows a check after successful refresh. The test covers polling, queued refresh, and refresh after unmount. The changelog documents the control and unavailable state on failure.

Merge Risk: 🔵 Low · up to 03623

A manual refresh can fail without trying to refresh usage when an overlapping automatic fetch fails. The user can retry, so this is a bounded issue rather than a merge blocker.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 03623

The refresh adds cache-changing authority to an existing API while preserving its login and cross-origin controls. Commands remain fixed and execution is bounded. Remaining uncertainty concerns the external cache’s ownership and coordination across server processes.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — Refresh operates on the process-wide usage cache and invokes CLI invalidation without provider, model or account scope arguments. Presentation filters therefore do not narrow invalidation authority. The exact persisted records and accounts affected cannot be established without the external CLI implementation.

Security Findings and Attack Paths

  • observed — A caller admitted by the existing API boundary can repeatedly request refresh=true, bypassing the normal cache lifetime and triggering fixed invalidation/retrieval work after preceding work settles. In-flight coalescing limits concurrent work within one process, but does not impose a sequential refresh cooldown. This is additional reachable work, not evidence of arbitrary command execution or a newly removed authentication control.

Trust Boundaries and Controls

  • observed — The unchanged proxy covers the route, rejects disallowed browser origins and requires a valid session when a web password is configured. Password-disabled access and acceptance of non-browser requests without origin headers predate this PR; the refresh adds cache-changing behavior behind that existing boundary.

Resilience and Maintainability Implications

  • inferred — The coordination guarantee is limited to one module instance. If multiple workers share the external persisted cache, their module-local promises cannot serialize invalidation across workers. Neither shared-store topology nor external locking is established by the available evidence, so a cross-process race is not retained as an observed finding.

Hardening Proposals

  • proposed — For deployments admitting multiple or less-trusted callers, consider a server-enforced refresh cooldown and document the CLI cache’s ownership and cross-process coordination guarantees. These are conditional hardening proposals, not verified vulnerabilities.

Comment thread lib/provider-usage.ts Outdated
A manual refresh must attempt cache invalidation even when the automatic fetch it waited behind rejects. Extend the CLI-backed regression to cover this failure path.
