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 for runtime strategies and derived public catalog membership
• 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 if it exists for an active provider-runtime goal. Treat any legacy tasks.md as migration input rather than another execution tracker.

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. After implementation, assess provider creation, auth handling, and model discovery for durable

regression coverage; add only the smallest contract-level tests warranted.

1. Update an active SDD plan.md as coherent implementation slices land, when one exists. For a

legacy tasks.md, merge remaining work into the existing plan; without one, keep a single-slice complex bug checklist in spec.md and create plan.md for feature, architecture, or multi-slice bug work. Do not update or recreate the task file.

1. Run:

pnpm run format
pnpm run i18n
pnpm run lint
pnpm run typecheck

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