Add Provider

Goal

Generate DeepChat provider integration changes against the current provider architecture. Keep provider display data in PublicProviderConf, map runtime behavior to known transports, and use a special provider implementation only when the API behavior requires one.

Required Inputs

Collect or derive these before editing source:

• Provider ID in kebab case.
• Display name.
• API type or known transport family.
• Default base URL.
• Auth type: API key, no auth, OAuth, profile credentials, or provider-specific credential.
• Model metadata source: built-in config, provider-db, config-db, live model fetch, or custom only.
• Test model ID and check strategy.
• Official website, API key URL, docs URL, model list URL.
• Request quirks: headers, endpoint suffixes, route rewrites, streaming shape, tool-call support,

reasoning support, image/audio/embedding endpoints, or proxy requirements.

Supported Paths

OpenAI-Compatible API

Use this when the provider supports OpenAI Chat Completions or Responses-compatible HTTP APIs.

Typical files:

• src/main/provider/defaults.ts
• src/main/provider/providerId.ts
• src/main/provider/providerRegistry.ts
• src/shared/providerDbCatalog.ts when models come from the public provider database
• test/main/** provider registry or creation tests

Existing Native Transport

Use this when the provider maps to an existing DeepChat transport such as Anthropic, Gemini, Vertex, Azure, Bedrock, Ollama, or ACP.

Typical files:

• src/main/provider/defaults.ts
• src/main/provider/providerRegistry.ts
• Settings components only when the existing generic form lacks required fields
• Focused tests for provider creation and connection checks

Special Provider

Use this when auth, request shape, streaming, discovery, or error handling differs from existing transports.

Typical files:

• src/main/provider/providers/<providerName>Provider.ts
• src/main/provider/<providerName>Adapter.ts
• src/main/provider/managers/providerInstanceManager.ts
• src/shared/contracts/routes/* and src/renderer/api/*Client.ts for interactive auth
• src/renderer/settings/components/* for provider-specific settings UI
• Main and renderer tests covering the new behavior

Guardrails

• Do not introduce ProviderRuntimeDefinition, generated runtime manifests, or runtime package-name

inference.

• Do not install provider SDK packages automatically.
• Do not execute provider logic in the renderer.
• Do not store new OAuth credentials in provider API-key fields.
• Do not add a special provider when a known transport and explicit config are sufficient.
• Reject the request when the required inputs cannot identify a safe path.

Workflow

1. Read docs/features/provider-runtime/spec.md when the provider work touches the provider runtime

scope. Also read plan.md and tasks.md if they exist for an active provider-runtime goal.

1. Inspect the current provider files before editing:

• src/main/provider/defaults.ts
• src/main/provider/providerId.ts
• src/main/provider/providerRegistry.ts
• src/main/provider/aiSdk/providerFactory.ts
• src/main/provider/managers/providerInstanceManager.ts
• src/renderer/settings/components/ProviderApiConfig.vue

1. Classify the request into one supported path.
2. Add the smallest explicit source changes for that path.
3. Add or update tests that prove provider creation, auth handling, and model discovery behavior.
4. Update the active SDD tasks.md entries as the work lands, when an active tasks file exists.
5. Run:

bash
pnpm run format
pnpm run i18n
pnpm run lint

Run focused main/renderer tests for any touched provider code.
