fix(auth): make chat login and model-access recovery actionable (#145051)
Keep saved credentials and observed model-access application distinct through chat and wizard completion. Share in-process refresh, renew expired access questions, and encode reserved provider names through one login-command owner.

Retained Gateway, Telegram and browser proofs cover the recovery paths. CI run 34670412955 attempt 1 passed with zero failed jobs. The consumer census and independent review accepted the exact head.

Step-by-step guide to building a model provider plugin for OpenClaw Building provider plugins Provider plugins
You are building a new model provider plugin
You want to add an OpenAI-compatible proxy or custom LLM to OpenClaw
You need to understand provider auth, catalogs, and runtime hooks

Build a provider plugin to add a model provider (LLM) to OpenClaw: a model catalog, API-key auth, and dynamic model resolution.

Acme AI is a fictional vendor used throughout this guide and its child pages. Helpers named fetchAcme* in the samples are placeholders for your own vendor API calls, not exported OpenClaw functions.

New to OpenClaw plugins? Read [Getting Started](/plugins/building-plugins) first for package structure and manifest setup. Provider plugins add models to OpenClaw's normal inference loop. If the model must run through a native agent daemon that owns threads, compaction, or tool events, pair the provider with an [agent harness](/plugins/sdk-agent-harness) instead of putting daemon protocol details in core.

Import an existing credential during sign-in

An auth method can declare credentialImport with a migrationProviderId, an exact itemId, and a credentialKind (api_key, oauth, or token). models auth login asks that migration owner for an auth-only plan before starting interactive sign-in. --force, --profile-id, and --set-default skip import. --set-default uses the auth method's recommended model through the normal sign-in flow.

The migration plugin declares its ID in contracts.migrationProviders and can export buildMigrationProvider() from a top-level migration-provider-api.ts public artifact. Keep that entry lightweight. Bundled plugins and enabled installed plugins can supply it without replacing the running plugin registry. Explicitly disabled or denied migration owners cannot execute their artifacts. The existing bundled migration compatibility rules still apply.

The login caller selects only the declared auth item. Its details must contain the matching provider and credentialKind. A migrated result also supplies the saved profileId. The owner must honor cancellation, reread the selected source before persistence, and reject a changed credential. Login passes configPatchMode: "none" so import preserves model defaults and restrictions. Unavailable storage or an unusable matching OAuth profile continues to interactive sign-in. A matching account identity alone does not make expired credentials usable. A failed selected import stops the operation instead of silently starting a different login.

Handle model access after sign-in

Existing consumers of runModelsAuthLoginFlow from openclaw/plugin-sdk/provider-auth-login-flow-runtime must handle a selection after credentials are saved. When effective restrictions can hide the provider's models, the existing prompter.select receives these options:

Value Label Effect
all Show all <Provider> models Adds that provider's wildcard to the existing policy owner.
keep Keep current restrictions Leaves restrictions unchanged.

Render the supplied message and options, and return the selected option's value. Do not assume that every select call chooses a provider or auth method. Neither choice activates a new default model. No choice is requested when restrictions are absent or already allow the whole provider.

Canceling or rejecting this post-save selection does not undo saved credentials. The flow throws ProviderAuthConfigApplyError, which extends ProviderCredentialsSavedError; report that credentials were saved instead of treating it as a failed credential exchange. Cancellation at the selection leaves restrictions unchanged. A later application failure can leave the policy saved but not active in the running Gateway. Keep credential persistence and model visibility outcomes distinct.

Defer the choice to a later reply

For chat buttons, pass the synchronous onModelAccessRequested callback. It receives a PreparedProviderModelAccess request and replaces the post-save select call; it does not apply the choice. Retain the prepared request until login finishes. Use createProviderLoginFlowRegistry and reserveProviderLoginFlow to reserve only the credential exchange.

After login finishes, call offerProviderLoginModelAccess with flows, flowKey, prepared, and terminalMessage. Deliver its structured reply. Always release the login in finally with releaseProviderLoginFlow({ flows, flowKey, record }). The pending model-access question has its own lifetime and remains answerable after that release; it does not block another login.

Pass the later command to answerProviderLoginModelAccess with flows, flowKey, agentId, command, runtime, readConfig, and assertCurrent; signal is optional. readConfig must return the host's current config. The owner validates the answer, applies the choice, and consumes that question. Expired or conflicting choices receive a fresh question based on current restrictions. Use cancelProviderLoginFlow({ flows, flowKey }) to cancel either pending phase. Do not reconstruct a wildcard write from button text or reuse a prepared request for a new login.

Keep hosted writes authorized

Hosted callers supply signal and assertCurrent to check the current login, sender authority, and selected provider/method before effects and after awaited work. An abort signal or matching login identifier alone is not current authorization. beforePersistentEffect remains the credential-persistence preparation callback. Browser authorization ends after the credential phase; the later model choice uses the current conversation or wizard authority.

For a deferred choice, pass the answering command's current authority check as answerProviderLoginModelAccess.assertCurrent. Use its config argument when supplied: it is the policy writer's current config. Otherwise read the host's current config. The original login callback does not authorize a later command. Let the shared owner report the visibility outcome: a saved policy is not proof that the running Gateway applied it.

`setup.providers[].envVars` lets OpenClaw detect credentials without
loading your plugin runtime. Add `providerAuthAliases` when a provider
variant should reuse another provider id's auth. `modelSupport` is
optional and lets OpenClaw auto-load your provider plugin from shorthand
model ids like `acme-large` before runtime hooks exist. `openclaw.compat`
and `openclaw.build` in `package.json` are required for ClawHub
publishing (`openclaw.compat.pluginApi` and `openclaw.build.openclawVersion`
are the two required fields. `minGatewayVersion` falls back to
`openclaw.install.minHostVersion` when omitted).

The version strings in the sample manifests are placeholders. Pin them to
the OpenClaw release your plugin builds and tests against.
A minimal text provider needs an `id`, `label`, `auth`, and `catalog`. `catalog` is the provider-owned runtime/config hook. It can call live vendor APIs and returns `models.providers` entries.
```typescript index.ts
import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";
import { createProviderApiKeyAuthMethod } from "openclaw/plugin-sdk/provider-auth";

export default definePluginEntry({
  id: "acme-ai",
  name: "Acme AI",
  description: "Acme AI model provider",
  register(api) {
    api.registerProvider({
      id: "acme-ai",
      label: "Acme AI",
      docsPath: "/providers/acme-ai",
      envVars: ["ACME_AI_API_KEY"],

      auth: [
        createProviderApiKeyAuthMethod({
          providerId: "acme-ai",
          methodId: "api-key",
          label: "Acme AI API key",
          hint: "API key from your Acme AI dashboard",
          optionKey: "acmeAiApiKey",
          flagName: "--acme-ai-api-key",
          envVar: "ACME_AI_API_KEY",
          promptMessage: "Enter your Acme AI API key",
          defaultModel: "acme-ai/acme-large",
        }),
      ],

      catalog: {
        order: "simple",
        run: async (ctx) => {
          const apiKey =
            ctx.resolveProviderApiKey("acme-ai").apiKey;
          if (!apiKey) return null;
          return {
            provider: {
              baseUrl: "https://api.acme-ai.com/v1",
              apiKey,
              api: "openai-completions",
              models: [
                {
                  id: "acme-large",
                  name: "Acme Large",
                  reasoning: true,
                  input: ["text", "image"],
                  cost: { input: 3, output: 15, cacheRead: 0.3, cacheWrite: 3.75 },
                  contextWindow: 200000,
                  maxTokens: 32768,
                },
                {
                  id: "acme-small",
                  name: "Acme Small",
                  reasoning: false,
                  input: ["text"],
                  cost: { input: 1, output: 5, cacheRead: 0.1, cacheWrite: 1.25 },
                  contextWindow: 128000,
                  maxTokens: 8192,
                },
              ],
            },
          };
        },
      },
    });

    api.registerModelCatalogProvider({
      provider: "acme-ai",
      kinds: ["text"],
      liveCatalog: async (ctx) => {
        const apiKey = ctx.resolveProviderApiKey("acme-ai").apiKey;
        if (!apiKey) return null;
        return [
          {
            kind: "text",
            provider: "acme-ai",
            model: "acme-large",
            label: "Acme Large",
            source: "live",
          },
        ];
      },
    });
  },
});
```

`registerModelCatalogProvider` is the newer control-plane catalog surface
for list/help/picker UI, covering `text`, `voice`, `image_generation`,
`video_generation`, and `music_generation` rows. Keep vendor endpoint
calls and response mapping in the plugin. OpenClaw owns the shared row
shape, source labels, and help rendering.

That is a working provider. Users can now run
`openclaw onboard --acme-ai-api-key <key>` and select
`acme-ai/acme-large` as their model.

For provider-key lookup and selection from an already loaded auth store,
import `findNormalizedProviderValue` and `resolveAuthProfileOrder` from
`openclaw/plugin-sdk/provider-auth`. This keeps provider entrypoints from
loading the full agent runtime just to select a credential. The deprecated
`agent-runtime` exports remain available for compatibility. Use the narrower
`provider-auth` route in new code. See the [removal
timeline](/plugins/sdk-migration/removal-timeline) for the dates and gates
that govern deprecated surfaces named on this page and its child pages.

A custom interactive auth method that mints a static token or API key can
request protected persistence on its returned profile:

```typescript
return {
  profiles: [
    {
      profileId: "acme-ai:device",
      credential: { type: "token", provider: "acme-ai", token },
      secretStorage: {
        kind: "store",
        namePrefix: "ACME_AI_TOKEN",
      },
    },
  ],
};
```

OpenClaw keeps the inline value only while staged validation runs. At the
final persistence boundary it writes the value to the protected local store
and saves a `tokenRef` or `keyRef` in the auth profile. `namePrefix` must be
an uppercase environment-style name. OpenClaw adds a stable suffix derived
from the provider and final profile id so multiple profiles remain separate.
Use this only for provider-minted static credentials, not rotating OAuth
credentials or values already supplied as SecretRefs.

For live `/models` discovery, catalog helpers, pricing normalization, and
the narrower single-provider entry point, see [Provider model
catalogs](/plugins/sdk-provider-plugins/model-catalogs).
If your provider accepts arbitrary model IDs (like a proxy or router), add `resolveDynamicModel`:
```typescript
api.registerProvider({
  // ... id, label, auth, catalog from above

  resolveDynamicModel: (ctx) => ({
    id: ctx.modelId,
    name: ctx.modelId,
    provider: "acme-ai",
    api: "openai-completions",
    baseUrl: "https://api.acme-ai.com/v1",
    reasoning: false,
    input: ["text"],
    cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
    contextWindow: 128000,
    maxTokens: 8192,
  }),
});
```

If resolving requires a network call, return the requested model directly
from `prepareDynamicModel`. OpenClaw applies the same configured overrides
and normalization as synchronous dynamic resolution. Existing hooks that
return nothing still retry `resolveDynamicModel` after preparation.
Most providers only need `catalog` + `resolveDynamicModel`. Add hooks incrementally as your provider requires them.
Start with the shared family builders in [Provider hook
families](/plugins/sdk-provider-plugins/hook-families), then wire individual
hooks with [Provider hook wiring](/plugins/sdk-provider-plugins/runtime-hooks).
### Step 5: Add extra capabilities
A provider plugin can register embeddings, speech, realtime transcription,
realtime voice, media understanding, image generation, video generation,
web fetch, and web search alongside text inference. OpenClaw classifies this as a
**hybrid-capability** plugin - the recommended pattern for company plugins
(one plugin per vendor). See
[Internals: Capability Ownership](/plugins/architecture#capability-ownership-model).

Register the audio capabilities from [Provider voice
capabilities](/plugins/sdk-provider-plugins/voice-and-audio). Register
embeddings, generation, fetch, and search from [Provider media and
search](/plugins/sdk-provider-plugins/media-and-search).
### Step 6: Test
```typescript src/provider.test.ts
import { describe, it, expect } from "vitest";
// Export your provider config object from index.ts or a dedicated file
import { acmeProvider } from "./provider.js";

describe("acme-ai provider", () => {
  it("resolves dynamic models", () => {
    const model = acmeProvider.resolveDynamicModel!({
      modelId: "acme-beta-v3",
    } as any);
    expect(model.id).toBe("acme-beta-v3");
    expect(model.provider).toBe("acme-ai");
  });

  it("returns catalog when key is available", async () => {
    const result = await acmeProvider.catalog!.run({
      resolveProviderApiKey: () => ({ apiKey: "test-key" }),
    } as any);
    expect(result?.provider?.models).toHaveLength(2);
  });

  it("returns null catalog when no key", async () => {
    const result = await acmeProvider.catalog!.run({
      resolveProviderApiKey: () => ({ apiKey: undefined }),
    } as any);
    expect(result).toBeNull();
  });
});
```

Publish to ClawHub

Provider plugins publish the same way as any other external code plugin:

clawhub package publish your-org/your-plugin --dry-run
clawhub package publish your-org/your-plugin

clawhub skill publish <path> is a different command for publishing a skill folder, not a plugin package - do not use it here.

Catalog order reference

catalog.order controls when your catalog merges relative to built-in providers:

Order When Use case
simple First pass Plain API-key providers
