[refactor] cleanup per-provider code in webview - #2299
Webview code created a number of provider registries duplicating what we already have. This PR cleans this up, reusing existing provider definition registry where possible and enhancing it where needed.
Test Procedure
unit, integration.
Pre-Submission Checklist
[n/a] Issue Linked: This PR is linked to an approved GitHub Issue (see "Related GitHub Issue" above).
Scope: My changes are focused on the linked issue (one major feature/fix per PR).
Self-Review: I reviewed my own code with care.
Writing Style: The PR title and description use Simplified Technical English (ASD-STE100): short sentences, plain words, active voice, one idea per sentence, no contractions.
Testing: New and/or updated tests have been added to cover my changes (if applicable).
Test Helpers (test changes only): Shared test helpers (src/test-utils/, @/utils/test-utils) are used only for mechanical duplication; test intent and scenario-specific mocks remain visible.
[n/a] Visual Snapshot (UI changes only): If a user would notice this change at a glance (layout, theme tokens, brand elements, empty/error states), I added or updated a *.visual.tsx snapshot in webview-ui/. See webview-ui/AGENTS.md → "When a UI change needs a snapshot".
Documentation Impact: I checked if my changes need documentation updates (see "Documentation Updates" section below).
…itions
Each provider definition now declares its user-facing `label` and, when it
ships one, its static `models` catalog. Two accessors mirror
`getProviderDefaultModelId`:
- `getProviderLabel(provider)` resolves the definition label, falling back to
the raw identifier.
- `getProviderModels(provider)` resolves the static catalog, falling back to an
empty map for providers discovered at runtime.
`MODELS_BY_PROVIDER` is removed; it duplicated every label and model list and
had drifted (e.g. "Fireworks" vs "Fireworks AI"). Consumers now read from the
definitions:
- webview `PROVIDERS` stores only `{ value, proxy }` and derives labels.
- `getStaticModelsForProvider`/`isStaticModelProvider` use `getProviderModels`.
- `getProviderServiceConfig` falls back to `getProviderLabel`.
- `ApiOptions` uses `getProviderModels` for reset validation and dropdown
filtering.
VS Code LM and GitHub Copilot keep a label but no static catalog because they
report models at runtime, preserving the previous dropdown behavior.
Provider settings now display consistent names and service links across supported providers.
Provider options are organized by display name, with proxy providers identified appropriately.
Static model catalogs are available where provided; providers that discover models at runtime continue to use dynamic model selection.
Changes
Gemini CLI and Fake AI are hidden from provider selection and treated as unsupported in the model selector.
Provider definitions now supply metadata used by shared accessors and webview components. The changes remove duplicated provider and model catalogs, add hidden-provider handling, and update tests for provider metadata, model selection, and filtering.
Provider definitions add labels and, where specified, service URLs and model catalogs. They also identify proxy and hidden providers.
Registry accessors and selectable providers packages/types/src/provider-settings.ts, packages/types/src/__tests__/*, packages/config-eslint/provider-identifiers.test.js
Shared accessors read metadata from provider definitions and provide fallbacks. selectableProviders excludes hidden definitions and sorts the remaining entries by label. Tests cover accessors, provider identifiers, and selectable providers.
Webview provider and model settings webview-ui/src/components/chat/*, webview-ui/src/components/settings/ApiOptions.tsx, webview-ui/src/components/settings/utils/*, webview-ui/src/components/settings/__tests__/*
Chat and settings components use shared provider accessors. Static model lookup uses catalogs from provider definitions, replacing the removed settings constants. Tests cover hidden providers and provider filtering.
The metadata refactor has no established runtime defect in the supplied evidence. Add reader/writer agreement coverage to protect model selection against future key drift; this is a bounded follow-up concern.

Full details: Title check
Explanation
The title "[refactor] cleanup per-provider code in webview" matches the main change. The PR removes duplicate provider registries in the webview (MODELS_BY_PROVIDER, PROVIDERS, and the providerModelConfig constants) and moves labels, model catalogs, service URLs, and flags into the shared provider definitions in packages/types. The title is short, names the area (webview), and conveys the refactor intent. It is a little broad, since the core change is moving metadata into provider definitions, but it is accurate.
Full details: Description check
Explanation
The description states the problem and the approach. It says webview code duplicated provider registries, and that the PR reuses and enhances the existing provider definition registry. It also includes the related-issue, test-procedure, and checklist sections from the template. Gaps: the issue link is marked n/a with no issue number, which conflicts with the template rule that every PR must link to an approved issue. The Test Procedure is only "unit, integration" with no concrete steps or results. The Description also omits the key implementation details the template asks for, such as the removed exports, the new accessors, and the trade-offs (for example, the hidden Fake AI and Gemini CLI handling, and the empty-catalog validation change). The Documentation Updates section and Get in Touch section are left as template placeholders. The description is mostly complete, so the check passes, but the author should address these points.
Resolution
Consider the following improvements before merge. Link an approved GitHub issue, or state why none is required under the project policy, because the template says every PR MUST be linked to an approved issue. Expand the Test Procedure with the specific unit and integration suites run and how a reviewer can repeat them. Add key implementation details to the Description, including the removed MODELS_BY_PROVIDER and PROVIDERS exports, the new provider accessors, and the behavior change for hidden providers and empty model catalogs. Mark the Documentation Updates section as checked or unchecked, and fill in the Get in Touch Discord username.
Full details: Regression Evidence
Explanation
The PR (Zoo-Code-Org/Zoo-Code #2299, author p12tic) moves provider labels, service URLs, models, proxy flags, and hidden flags into provider definitions. It removes MODELS_BY_PROVIDER, PROVIDERS, and getProviderServiceConfig, and it routes the webview through new accessors. I checked the three gaps named by the standing failure against the current head. 1. Proxy branch in ErrorRow (ErrorRow.tsx:102). The only changed line is usesProxy = isProviderName(provider) ? getProviderIsProxy(provider) : false. The proxy flags did not change. The base PROVIDERS marks openai, lmstudio, ollama, and litellm as proxies. Head declares isProxy: true in openai.ts, lm-studio.ts, ollama.ts, and litellm.ts. provider-settings.test.ts (lines 118-136) asserts getProviderIsProxy for those four providers (true) and for anthropic, openrouter, gemini, and bedrock (false). The unregistered-provider path (test-provider) is covered by the existing ErrorRow spec. The proxy-notice rendering branch is unchanged. The behavior is preserved and the flag mapping has focused types-level coverage. An ErrorRow proxy case would be useful but is not required by this check. 2. Visible xAI hint text and Playwright snapshot. The generic picker now shows getProviderLabel("xai"), which is "xAI (Grok)", where the base showed "xAI". This is a copy change to a provider display name. The repository policy in webview-ui/AGENTS.md (lines 46-57) requires a *.visual.tsx snapshot for changes users notice at a glance, such as layout, spacing, theme tokens, brand elements, and empty or error states. A provider display name in a hint string does not fall in those categories. The PR template also marks the visual snapshot as n/a. The check does not require a snapshot here. 3. ApiOptions wiring for xAI. The change passes getProviderLabel and getProviderServiceUrl directly to ModelPicker props. The label value is declared in xai.ts and the label source is covered by the types-level label tests. The wiring is a mechanical source substitution. The check does not require a test for every mechanical configuration change. Residual note: the xAI display text change is user-visible and was not called out in the PR description. A maintainer may want to confirm it is intentional. This is not a regression-evidence failure under the stated criteria. Prior failure refuted: (1) The xAI hint text change is a provider display-name copy change. It is not a layout, theme, brand, or state change, so the AGENTS.md snapshot rule does not require a Playwright snapshot. (2) ErrorRow proxy behavior is preserved. openai, lmstudio, ollama, and litellm keep isProxy true, and provider-settings.test.ts lines 118-136 assert these flags at the types layer. The ErrorRow change is a...
Full details: Security Boundaries
Explanation
The PR is a provider-registry refactor. It moves labels, service URLs, static model catalogs, proxy flags, and hidden flags from webview constants into packages/types provider definitions. I found no changed path that leaks secrets or PII, trusts or executes unvalidated input, or bypasses approval or allowlist controls. Evidence from the reviewed diff: - Service URLs:getProviderServiceUrl supplies the serviceUrl prop in ApiOptions.tsx, which feeds ModelPicker's VSCodeLink href. The values are hardcoded literals in provider definitions. No user input reaches this path. - Hidden providers:ModelSelector.getModelIdField now returns undefined for hidden providers (Fake AI, Gemini CLI). This restricts the quick picker. It does not widen access. selectableProviders also excludes hidden definitions. - Organization allowlist:filterProviders still applies to selectableProviders. getModelValidationError in webview-ui/src/utils/validate.ts still calls validateProviderAgainstOrganizationSettings with organizationAllowList. The removed validateAndResetModel path in onProviderChange was a UI reset helper. Its change does not disable the allowlist check. - Model-ID keys:getProviderModelIdKey returns a key from trusted provider definitions. It is not built from user input. - ErrorRow:getProviderIsProxy only changes display metadata. One behavior change is worth noting. validateAndResetModel now skips providers with empty static catalogs. The previous code compared against a metadata object, so this is a correctness and UX change, not a security boundary bypass. It is outside this check's criteria.
Full details: Persistence Integrity
Explanation
The check fails only when a changed persistence path can lose or corrupt state through an unawaited operation, a non-atomic write, missing rollback or partial-failure handling, or a persisted default not reaching a consumer. The PR is a webview refactor of provider metadata. The changed-file inventory (refs/coderabbit/pre-merge-check/base..head) has no write, save, or storage-related edits. A diff grep for await, globalState, secrets, saveConfig, postMessage, writeFile, persist, and flush found only comments mentioning "persisted settings". Provider definitions gain label, serviceUrl, models, isProxy, and hidden fields. ApiOptions.tsx and ModelSelector.tsx now read these through accessors. The one default-propagation path is ApiOptions validateAndResetModel, which now takes getProviderDefaultModelId(value, apiConfiguration) in place of config.default from PROVIDER_MODEL_CONFIG. Both sides read the same per-provider getDefaultModelId accessor. The old zai branch also used getDefaultModelIdForProvider. I did not verify every per-provider default value against the old table, so this is a residual gap. It is not a changed-path failure under the check. The hidden-provider change only affects which model-ID field the quick picker reads. It does not write persisted state.
Full details: Lifecycle Resource Cleanup
Explanation
The check fails only when a changed lifecycle path can leak a listener, watcher, provider, timer, task, or other resource, or duplicate work after cancellation, disposal, or restart. I inspected the PR's committed range (base to head, 53 files). - The diff is a data-registry refactor. It moves labels, service URLs, static model catalogs, model-ID keys, proxy and hidden flags into provider definitions in packages/types/src/providers/*.ts and provider-settings.ts. It also rewires consumers in ApiOptions.tsx, ModelSelector.tsx, ErrorRow.tsx, and providerModelConfig.ts. - A search of added and removed lines found no listeners, subscriptions, timers, watchers, abort controllers, disposables, or async task handling. The only removed "Cleanup" blocks are in ApiOptions.provider-filtering.spec.tsx. They deleted synthetic entries from the now-removed MODELS_BY_PROVIDER and PROVIDERS globals. They are test-only and do not touch runtime resources. - ApiOptions.tsx changes the model-validation and provider-option filters. These are synchronous lookups in render and effect logic. They add no new effect, timer, or request lifecycle. No changed path matches the failure condition, so the check passes.

Move the settings-UI provider list out of the webview and into the provider
definitions:
- Add optional `isProxy` and `hidden` to `ProviderDefinitionInput`; both
default to `false` in `createProviderDefinition`.
- Mark the user-configured endpoints (OpenAI Compatible, LiteLLM, Ollama,
LM Studio) with `isProxy: true`, matching the previous webview list.
- Mark `gemini-cli` (compatibility shim) and `fake-ai` (test-only) as
`hidden`, so they stay registered without being offered in the picker.
- Add `getProviderIsProxy` and `isProviderHidden` accessors plus a derived
`selectableProviders` list in `provider-settings.ts`.
- Delete `webview-ui/src/components/settings/constants.ts`; `ApiOptions` and
`ErrorRow` now read the definitions directly.
Adding a provider no longer requires a second registry entry.
Move the console/documentation URL out of the webview-side PROVIDER_SERVICE_CONFIG registry and into each provider definition, alongside label, models, isProxy, and hidden.
- ProviderDefinition gains a required serviceUrl; createProviderDefinition accepts it optionally and defaults to an empty string for proxies, local servers, and hidden providers.
- Add getProviderServiceUrl() to provider-settings.ts, mirroring getProviderLabel(), returning an empty string for unregistered providers.
- Delete PROVIDER_SERVICE_CONFIG, ProviderServiceConfig, and getProviderServiceConfig from the settings utils.
- ApiOptions now derives serviceName from getProviderLabel() and serviceUrl from getProviderServiceUrl(), removing the duplicated service-name strings.
- Cover the new accessor in provider-settings tests and update the ESLint rule fixtures to the new function name.
Replace the webview-side model-ID registries with the provider definitions
that already own this data:
- Add getProviderModelIdKey(provider) to provider-settings.ts as the write
counterpart of getModelId(), returning the definition's modelIdKey.
- Delete PROVIDER_MODEL_CONFIG, PROVIDER_DEFAULT_MODEL_IDS,
getProviderModelConfig and getDefaultModelIdForProvider from
providerModelConfig.ts.
- ApiOptions derives the model field from getProviderModelIdKey and the
fallback from getProviderDefaultModelId, which also fixes the two
registries disagreeing about defaults for the dynamic providers.
- ModelSelector keeps hidden providers (Fake AI, Gemini CLI) unsupported,
matching the previous absence of a config entry for them.
Assert that getModelId() reads each declared modelIdKey.
The matrix compares each modelIdKey only with its own definition, and checks only that it is a valid settings key. Pointing OpenAI Compatible's key at openAiBaseUrl would still pass, while getModelId() keeps reading openAiModelId. Assert that getModelId() returns the value stored under each declared key.

Extend the provider-definition test matrix around getProviderModelIdKey to
verify getModelId returns the value stored under each definition’s declared
modelIdKey, using distinct test values so an incorrect key cannot pass.
