# Auto-Discovery on Provider Activation — Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

**Goal:** When a provider is activated (OAuth callback or API key save+test), automatically trigger model discovery and profiling so ModelProfile records exist for the routing pipeline.

**Architecture:** The OAuth callback route (`provider-oauth.ts:exchangeOAuthCode`) and the ProviderDetailForm save flow (`ai-providers.ts:configureProvider`) both activate providers but never trigger `discoverModelsInternal` + `profileModelsInternal`. The routing loader (`loader.ts:loadEndpointManifests`) queries ModelProfile with active providers — zero profiles means zero routable models. The fix adds an `autoDiscoverAndProfile()` function called from both activation paths, plus a known-model catalog for providers that can't use `/v1/models` (ChatGPT, Codex).

**Tech Stack:** Next.js server actions, Prisma ORM, provider adapter registry

## Problem Analysis

### Current Flow (broken)

```
OAuth callback → exchangeOAuthCode()
  → stores token in CredentialEntry
  → sets provider.authMethod = "oauth2_authorization_code"
  → activates sibling providers (codex↔chatgpt)
  → redirects to /platform/ai/providers/{id}?oauth=success
  → NO discovery, NO profiling
  → routing pipeline finds 0 ModelProfiles → falls through
```

```
API key save → configureProvider()
  → stores encrypted key in CredentialEntry
  → updates enabledFamilies, authMethod
  → NO discovery, NO profiling
  → admin must manually click "Discover Models" in ProviderDetailForm
```

### Target Flow (fixed)

```
OAuth callback → exchangeOAuthCode()
  → stores token, activates provider
  → calls autoDiscoverAndProfile(providerId)
  → for discoverable providers: fetches /v1/models, creates DiscoveredModel + ModelProfile
  → for non-discoverable providers (chatgpt, codex): seeds from KNOWN_PROVIDER_MODELS catalog
  → routing pipeline finds ModelProfiles → models available immediately
```

```
ProviderDetailForm "Save & Test" → configureProvider() + testProviderAuth()
  → if auth test passes, triggers autoDiscoverAndProfile()
  → same result: models available for routing immediately
```

### Why non-discoverable providers need a catalog

`discoverModelsInternal()` skips providers where `authMethod === "oauth2_authorization_code" && (category === "agent" || providerId === "chatgpt")` because subscription tokens can't call `/v1/models`. These providers need pre-seeded models. The seed runs at container startup, but if someone connects ChatGPT *after* the initial seed, the models exist in `seed.ts` but not in the DB yet. The catalog provides the same data on-demand.

---

## Task 1: Create the known-model catalog

Build a static lookup table mapping provider IDs to their known models with capabilities, so non-discoverable providers get ModelProfile records without calling `/v1/models`.

**Files:**
- Create: `apps/web/lib/routing/known-provider-models.ts`
- Reference: `packages/db/src/seed.ts:730-854` (existing seedCodexModels + seedChatGPTModels)
- Reference: `apps/web/lib/routing/adapter-anthropic.ts` (capability shape)

### Steps

- [ ] **Step 1: Create known-provider-models.ts with type definition and catalog**

```typescript
// apps/web/lib/routing/known-provider-models.ts
// Static catalog of models for providers that can't use /v1/models discovery.
// Used by autoDiscoverAndProfile() to seed DiscoveredModel + ModelProfile
// when a non-discoverable provider is activated.

feat(routing): add known-model catalog for non-discoverable providers

Codex and ChatGPT providers can't use /v1/models discovery.
This catalog provides the same model data on-demand during
provider activation.
```

## Task 2: Create autoDiscoverAndProfile() function

This function encapsulates the discover→profile pipeline and handles both discoverable and non-discoverable providers.

**Files:**
- Modify: `apps/web/lib/ai-provider-internals.ts` (add new exported function)
- Reference: `apps/web/lib/ai-provider-internals.ts:166-289` (discoverModelsInternal)
- Reference: `apps/web/lib/ai-provider-internals.ts:297-573` (profileModelsInternal)
- Reference: `apps/web/lib/routing/known-provider-models.ts` (from Task 1)

### Steps

- [ ] **Step 1: Add import for KNOWN_PROVIDER_MODELS at top of ai-provider-internals.ts**

After the existing imports (around line 15), add:

```typescript
import { KNOWN_PROVIDER_MODELS, type KnownModel } from "@/lib/routing/known-provider-models";
```

- [ ] **Step 2: Add autoDiscoverAndProfile() function**

Add at the end of `ai-provider-internals.ts` (after `backfillModelCards`), before any other exports at the bottom:

```typescript
/**
 * Auto-discover and profile models for a provider after activation.
 * Called from OAuth callback and API key save flows.
 *
 * For discoverable providers: calls discoverModelsInternal + profileModelsInternal.
 * For non-discoverable providers (chatgpt, codex): seeds from KNOWN_PROVIDER_MODELS catalog.
 *
 * Runs in the background — caller should not await if it's in a redirect path.
 * Errors are logged but never thrown (activation should succeed even if discovery fails).

feat(routing): add autoDiscoverAndProfile() for provider activation

Encapsulates discover→profile pipeline for both discoverable providers
(calls /v1/models) and non-discoverable providers (seeds from catalog).
```

---

## Task 3: Hook into OAuth callback flow

Call `autoDiscoverAndProfile()` after successful token exchange. The OAuth callback is a GET redirect — we fire discovery as a fire-and-forget promise so the redirect isn't blocked.

**Files:**
- Modify: `apps/web/lib/provider-oauth.ts:159-217` (after credential upsert, before flow cleanup)

### Steps

- [ ] **Step 1: Add import at top of provider-oauth.ts**

After the existing imports (line 7):

```typescript
import { autoDiscoverAndProfile } from "@/lib/ai-provider-internals";
```

- [ ] **Step 2: Add auto-discovery call after provider activation**

In `exchangeOAuthCode()`, after the provider auth method is set (line 164, `data: { authMethod: "oauth2_authorization_code" }`), and before the linked MCP server activation (line 168), add:

```typescript
  // Auto-discover and profile models now that the provider has valid credentials.
  // Fire-and-forget — don't block the OAuth redirect. Errors are logged internally.
  autoDiscoverAndProfile(flow.providerId).catch(() => {});
```

- [ ] **Step 3: Add auto-discovery for sibling providers (codex↔chatgpt)**

In the sibling sync block (around line 213, after the sibling provider is activated), add:

```typescript
      // Also discover models for the sibling provider
      autoDiscoverAndProfile(sibling).catch(() => {});
```

This goes after the `prisma.modelProvider.update` that sets sibling to "active" (around line 213).

- [ ] **Step 4: Commit**

```
feat(routing): trigger auto-discovery after OAuth provider activation

After OAuth token exchange, fire-and-forget discovery+profiling so
models are available for routing without manual admin intervention.
Also triggers for sibling providers (codex<->chatgpt).
```

---

## Task 4: Hook into API key save+test flow in ProviderDetailForm

The ProviderDetailForm already calls `testProviderAuth()` then `discoverModels()` then `profileModels()` manually. But `configureProvider()` (the save action) doesn't trigger discovery. The real gap is that after OAuth success, the user lands on the provider page and the ProviderDetailForm shows step 4 ("Discover Models") — but for OAuth providers the discovery already happened server-side (Task 3). The form should detect this.

However, the simpler and more impactful fix is server-side: when the OAuth callback redirects to `/platform/ai/providers/{id}?oauth=success`, the page load should verify models exist. If not (e.g., the fire-and-forget from Task 3 hasn't completed yet), the form's existing "Discover Models" button still works as a fallback.

No code change needed in ProviderDetailForm — Task 3 handles the server-side hook. The existing manual flow in ProviderDetailForm is already correct as a fallback.

**However**, there is one improvement: the ProviderDetailForm `handleSave` function already runs discover+profile after save+test (lines 125-140). But `configureProvider()` the server action does not. If someone saves via API/script without the form, they'd miss discovery. Let's add auto-discovery to `testProviderAuth()` success path as well.

**Files:**
- Modify: `apps/web/lib/actions/ai-providers.ts` (testProviderAuth action)

### Steps

- [ ] **Step 1: Add import in ai-providers.ts**

At the top of `apps/web/lib/actions/ai-providers.ts`, check if `autoDiscoverAndProfile` is importable from internals. Add to the existing import from `ai-provider-internals.ts`:

Find the import line (around line 15):
```typescript
import {
  discoverModelsInternal,
  profileModelsInternal,
```

Add `autoDiscoverAndProfile`:
```typescript
import {
  autoDiscoverAndProfile,
  discoverModelsInternal,
  profileModelsInternal,
```

- [ ] **Step 2: Add auto-discovery to testProviderAuth on success**

In the `testProviderAuth` function, after the successful auth test sets `status: "active"` and returns `{ ok: true, ... }`, add a fire-and-forget discovery call. Find the success return (use grep for `"Connection verified"` or similar in ai-providers.ts).

The function likely updates the provider status to "active" and the credential status to "ok" on success. After those DB writes, before the return, add:

```typescript
    // Auto-discover models now that auth is confirmed
    autoDiscoverAndProfile(providerId).catch(() => {});
```

**Important:** Only add this if there isn't already a discovery call in the success path. The ProviderDetailForm calls discover separately after testProviderAuth returns, so this would be a belt-and-suspenders — the first to complete wins (upserts are idempotent).

- [ ] **Step 3: Verify compilation**

```bash
pnpm --filter @dpf/web exec tsc --noEmit 2>&1 | tail -10
```

- [ ] **Step 4: Commit**

```
feat(routing): trigger auto-discovery after successful provider auth test

Belt-and-suspenders: server-side discovery runs even if the UI
flow doesn't call discoverModels() separately.
```

---

## Task 5: Write integration test for autoDiscoverAndProfile

**Files:**
- Create: `apps/web/lib/auto-discover.test.ts`
- Reference: `apps/web/lib/ollama-health.test.ts` (pattern for mocking discover/profile internals)

### Steps

- [ ] **Step 1: Write the test file**

Note: `autoDiscoverAndProfile` calls `discoverModelsInternal` and `profileModelsInternal` as same-module function calls, so vitest module mocks won't intercept them. We test two paths: (1) known-model catalog path via Prisma mocks, (2) the catalog lookup logic directly.

```typescript
// apps/web/lib/auto-discover.test.ts
import { describe, it, expect, vi, beforeEach } from "vitest";
import { KNOWN_PROVIDER_MODELS } from "@/lib/routing/known-provider-models";

describe("KNOWN_PROVIDER_MODELS catalog", () => {
  it("has entries for non-discoverable providers", () => {
    expect(KNOWN_PROVIDER_MODELS.codex).toBeDefined();
    expect(KNOWN_PROVIDER_MODELS.codex.length).toBeGreaterThan(0);
    expect(KNOWN_PROVIDER_MODELS.chatgpt).toBeDefined();
    expect(KNOWN_PROVIDER_MODELS.chatgpt.length).toBeGreaterThan(0);
  });

  it("does not have entries for discoverable providers", () => {
    expect(KNOWN_PROVIDER_MODELS["anthropic"]).toBeUndefined();
    expect(KNOWN_PROVIDER_MODELS["anthropic-sub"]).toBeUndefined();
    expect(KNOWN_PROVIDER_MODELS["openai"]).toBeUndefined();
    expect(KNOWN_PROVIDER_MODELS["gemini"]).toBeUndefined();
    expect(KNOWN_PROVIDER_MODELS["ollama"]).toBeUndefined();
  });

  it("codex model matches seed.ts data", () => {
    const codex = KNOWN_PROVIDER_MODELS.codex[0];
    expect(codex.modelId).toBe("codex-mini-latest");
    expect(codex.modelClass).toBe("agent");
    expect(codex.costTier).toBe("$$");
    expect(codex.capabilities.toolUse).toBe(true);
    expect(codex.scores?.codegen).toBe(90);
    expect(codex.scores?.reasoning).toBe(70);
  });

  it("chatgpt model matches seed.ts data", () => {
    const gpt = KNOWN_PROVIDER_MODELS.chatgpt[0];
    expect(gpt.modelId).toBe("gpt-5.4");
    expect(gpt.modelClass).toBe("chat");
    expect(gpt.costTier).toBe("subscription");
    expect(gpt.capabilities.toolUse).toBe(true);
    expect(gpt.capabilities.imageInput).toBe(true);
    expect(gpt.scores?.reasoning).toBe(85);
    expect(gpt.scores?.codegen).toBe(90);
  });

  it("all models have required fields", () => {
    for (const [providerId, models] of Object.entries(KNOWN_PROVIDER_MODELS)) {
      for (const m of models) {
        expect(m.modelId, `${providerId}/${m.modelId} missing modelId`).toBeTruthy();
        expect(m.friendlyName, `${providerId}/${m.modelId} missing friendlyName`).toBeTruthy();
        expect(m.modelClass, `${providerId}/${m.modelId} missing modelClass`).toBeTruthy();
        expect(m.capabilities, `${providerId}/${m.modelId} missing capabilities`).toBeDefined();
        expect(m.inputModalities.length, `${providerId}/${m.modelId} empty inputModalities`).toBeGreaterThan(0);
        expect(m.outputModalities.length, `${providerId}/${m.modelId} empty outputModalities`).toBeGreaterThan(0);
      }
    }
  });
});
```

For the `autoDiscoverAndProfile` function itself, integration testing via the manual flow (Task 6) is more reliable than trying to mock same-module function calls. The catalog tests above validate the data correctness, and the existing discovery/profiling tests cover those functions independently.

- [ ] **Step 2: Run the test**

```bash
cd h:/opendigitalproductfactory
pnpm --filter @dpf/web exec vitest run apps/web/lib/auto-discover.test.ts 2>&1 | tail -20
```

- [ ] **Step 3: Fix any failures, re-run until green**

- [ ] **Step 4: Commit**

```
test(routing): add integration tests for autoDiscoverAndProfile
```

---

## Task 6: Verify end-to-end with manual testing

This task validates the full flow works in the running application.

**Files:**
- Reference: `apps/web/lib/provider-oauth.ts` (OAuth flow)
- Reference: `apps/web/components/platform/ProviderDetailForm.tsx` (UI)

### Steps

- [ ] **Step 1: Rebuild the portal image**

Per feedback_no_destructive_without_approval.md — list the commands first, get approval:

```
1. docker compose build portal
2. docker compose up -d portal portal-init
```

- [ ] **Step 2: Test OAuth activation flow**

1. Go to `/platform/ai/providers/anthropic-sub`
2. Click "Sign in with Anthropic"
3. Complete OAuth flow
4. After redirect, check the Models section — should show discovered models immediately
5. Go to `/platform/ai` overview — provider should show model count

- [ ] **Step 3: Test API key activation flow**

1. Go to `/platform/ai/providers/openai` (or another API key provider)
2. Enter API key
3. Click "Save & Test"
4. After success, check Models section — should auto-populate

- [ ] **Step 4: Verify routing works**

1. Go to any agent chat (e.g., Build Studio)
2. Send a message
3. Check the routing log — should find models from the newly activated provider

## Summary of Changes

| File | Change | Purpose |
|------|--------|---------|
| `apps/web/lib/routing/known-provider-models.ts` | **Create** | Static catalog for non-discoverable providers |
| `apps/web/lib/ai-provider-internals.ts` | **Add** `autoDiscoverAndProfile()` + `seedKnownModels()` | Encapsulate discover→profile with catalog fallback |
| `apps/web/lib/provider-oauth.ts` | **Add** fire-and-forget call after token exchange | OAuth activation triggers discovery |
| `apps/web/lib/actions/ai-providers.ts` | **Add** import + call in testProviderAuth success | API key activation triggers discovery |
| `apps/web/lib/auto-discover.test.ts` | **Create** | Integration tests |

### What this does NOT change

- The existing manual "Discover Models" / "Sync Models" buttons in ProviderDetailForm — they remain as a manual fallback
- The routing pipeline (`loader.ts`, `cost-ranking.ts`) — no changes needed, it already works correctly once ModelProfile records exist
- The adapter registry — adapters are already correct
- The seed.ts functions — they remain for initial container startup; the catalog duplicates their data for runtime use

### Risks

1. **Race condition on OAuth redirect:** The fire-and-forget discovery may not complete before the user sees the provider page. Mitigation: the ProviderDetailForm already shows a "Discover Models" button as step 4, and the user can click it. The auto-discovery is belt-and-suspenders.

2. **Double discovery:** If the ProviderDetailForm's existing manual flow fires at the same time as the auto-discovery, both will upsert the same records. Mitigation: all writes use `upsert` with unique constraints — idempotent by design.

3. **ChatGPT SSE adapter still broken:** Per `project_routing_findings.md`, the ChatGPT SSE adapter returns empty responses. Creating ModelProfile records for `chatgpt/gpt-5.4` means the router will try to use it and get empty responses. Mitigation: this is a separate bug (EP-INF-XXX). The model profiles are still correct — the adapter needs fixing, not the discovery.
