📝 Walkthrough

Walkthrough

OpenRouter model loading now forwards API keys and base URLs, scopes caches by credentials, retrieves authenticated models and presets, and represents presets as synthetic models. Webview flows and tests now preserve and validate preset selections.

Changes

OpenRouter model discovery

Layer / File(s) Summary
Authenticated models and presets
src/shared/api.ts, src/api/providers/fetchers/openrouter.ts, src/api/providers/fetchers/__tests__/openrouter.spec.ts
OpenRouter requests now support authentication, user models, presets, preset parsing, synthetic @preset/... models, and preset metadata.
Credential-aware caching and propagation
src/api/providers/fetchers/modelCache.ts, src/api/providers/openrouter.ts, src/core/webview/webviewMessageHandler.ts, src/api/providers/fetchers/__tests__/modelCache.spec.ts, src/core/webview/__tests__/*
OpenRouter cache keys include API-key discriminators. Model-loading paths forward credentials and base URLs.
Preset selection and validation
webview-ui/src/components/ui/hooks/__tests__/useSelectedModel.spec.ts, webview-ui/src/utils/__tests__/validate.spec.ts
Tests verify that configured OpenRouter presets remain selected and pass validation with their metadata.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 09296

OpenRouter presets may use the wrong cached models or fail to discover models when custom base URLs are configured, and the affected preset tests currently fail. The PR is not merge-ready until these bounded correctness and test issues are resolved or explicitly accepted.

Replace the as any mock casts.

Use typed mock results or precise test doubles. The two as any casts disable type checking for the hook data contract.

As per coding guidelines: “Avoid as any; use typed APIs, bracket notation for private members where necessary, or precise test doubles and unknown type guards.”

In `@src/api/providers/fetchers/__tests__/openrouter.spec.ts`:
- Around line 610-614: Update the preset expectations in the openrouter model
tests to assert the synthesized contextWindow and fallback description produced
by getOpenRouterModels(), replacing the not.toHaveProperty checks for each
affected preset block while preserving the existing supportsPromptCache
assertion.

In `@src/api/providers/fetchers/modelCache.ts`:
- Line 93: Add OpenRouter’s provider identifier to URL_SCOPED_PROVIDERS so
model-cache entries include the configured base URL. Add coverage verifying
identical OpenRouter key discriminators with distinct base URLs produce separate
cache entries and results.

In `@src/core/webview/webviewMessageHandler.ts`:
- Around line 1101-1113: Resolve openRouterBaseUrl from message.values with the
saved apiConfiguration fallback in the webview message handler. Pass it to both
the OpenRouter flushModels call and the openrouter candidate options, preserving
explicit message values over saved configuration. Add coverage for saved and
unsaved base URLs.

In `@webview-ui/src/components/settings/ModelInfoView.tsx`:
- Around line 60-67: Add focused rendering coverage for the ModelInfoView
context-window condition: verify models whose selectedModelId starts with
“@preset/” do not render the context-window label or token value, while a normal
model with a positive numeric contextWindow still renders it. Keep the test
scoped to this UI behavior and use the existing component test patterns.
