Intent

The package layer carries the contracts the rest of the codebase consumes. v2 changes here are mostly:

1. Adding adapterFamily to the EndpointConfig schema everywhere (catalog schema, runtime schema, helpers).
2. Lifting provider-shape predicates out of the renderer into @shared/utils so Main can use the same checks.
3. The ProviderExtension upgrade for toolFactories (per-capability factory functions) and the resulting ExtensionRegistry.resolveToolCapability path used by the providerToolPlugin.

Key changes

packages/aiCore

core/providers/core/ProviderExtension.ts

Adds toolFactories: ToolFactoryMap<TProvider> to ProviderExtensionConfig. Each entry is (provider) => (config) => ToolFactoryPatch. The patch carries tools and/or providerOptions, so a single capability (e.g. webSearch) can produce multi-tool patches (xAI's webSearch + xSearch) or non-tool patches (OpenRouter's providerOptions).

ExtractToolConfig<TExt, K> extracts the config type from the declaration; WebSearchToolConfigMap is auto-generated from coreExtensions. Result: per-provider webSearch config typing is inferred from the extension declaration — UI form fields can be strongly typed against the per-vendor shape.

See the core architecture's Tool capability resolution.

core/runtime/types.ts

Small type-only changes — StringKeys<T> helper export, runtime parameter shape adjustments.

packages/provider-registry

data/providers.json

Per-provider, per-endpoint adapterFamily field added across the catalog. Audit: 100% of entries have adapterFamily on every endpoint.

src/schemas/provider.ts

RegistryEndpointConfigSchema.adapterFamily: z.string(). Schema validates the catalog at load time; missing adapterFamily fails fast.

src/registry-utils.ts

• inferAdapterFamily(endpointType, catalogConfig?) — the single source of truth for derivation. Catalog wins; otherwise endpoint-type default table; otherwise 'openai-compatible'.
• buildPersistedEndpointConfigs(...) — copies connection fields such as adapterFamily through the catalog → runtime endpoint config transformation.
• lookupRegistryModel / lookupRegistryProvider — name lookup helpers used by the migrator.

src/registry-loader.ts

Three-layer cache (mtime, v8.serialize, O(1) lookup) — see memory: Registry perf plan. Hot on app boot; matters because migrations also call findProvider(id) per row.

src/patterns/vendor-patterns.ts

Vendor capability inference patterns. Added entries for new providers.

packages/shared/data/types/provider.ts

EndpointConfigSchema.adapterFamily: z.string() — the runtime counterpart of the registry schema. Loaded provider rows must have adapterFamily per endpoint; absent rows fail schema parsing.

DEFAULT_API_FEATURES — runtime defaults for the per-provider features section.

packages/shared/utils/provider.ts + providerTopology.ts

Moved out of the renderer in commits:

• c75b08597 refactor(provider-utils): unify ProviderSettings predicate fork into @shared
• ae3306305 refactor(blacklist-pattern): move blacklistMatchPattern to @shared, drop main port
• 617a17509 refactor(store-migrate): inline 3 predicates, delete dead v1 @renderer/utils/provider

Predicates: isOpenAIProvider, isAnthropicProvider, etc. Topology helpers: walk model lists by capability, find default chat endpoint.

packages/shared/aiCore/provider/utils/

Provider configuration helpers used by both Main and (legacy) renderer during transition. api.ts carries common host-normalisation logic.

Invariants

• adapterFamily is REQUIRED on every endpoint config — schema enforced, no implicit defaults at runtime.
• inferAdapterFamily is the only function allowed to compute adapterFamily; UI forms / migrators / seeders all call it.
• ProviderExtension's toolFactories registrations are declared as const satisfies ProviderExtensionConfig<...> so the config type flows through correctly. Skipping this loses inference.

Validation

• packages/provider-registry/src/__tests__/registry-utils.test.ts — catalog wins, endpoint defaults, openai-compatible terminal fallback, dual schema acceptance (5 cases) + buildPersistedEndpointConfigs passthrough (9 cases).
• packages/aiCore test suite (provider extension cache + tool resolution).
• Renderer / Main consumers test the resolver behaviour at their level (see provider-cluster.md).

Follow-ups (out of scope)

• packages/aiCore test infrastructure could lift to share with Main-side test helpers (@cherrystudio/ai-core/test_utils already exists — coverage of variant resolution edge cases).
• Some renderer-only @renderer/utils/provider files still exist; the inlining chain (commits 617a17509, ae3306305) covers most but a final pass is pending.
