Explicit chains vs automatic model equivalence -**Decision:** Explicit user-configured chains. -**Why:** Automatic equivalence is unreliable — models with the same name from different -providers may have different capabilities, limits, or pricing. Users should explicitly -opt in to which models they consider interchangeable. - -### 2. Where fallback sits in the retry flow -**Decision:** After credential rotation, before exponential backoff. -**Why:** Provider fallback is a better recovery than waiting and retrying the same -exhausted provider. If the fallback also fails, exponential backoff still kicks in. - -### 3. Model swap vs new agent -**Decision:** Swap model on existing agent mid-conversation. -**Why:** Creating a new agent would lose conversation context. The agent's `streamFn` -already accepts model as a parameter, and `getApiKey` resolves per-provider, so -swapping is straightforward. - -### 4. Restoration strategy -**Decision:** Check before each request (lazy check on backoff expiry). -**Why:** No background timers needed. The cost of one `isProviderAvailable()` check -per request is negligible. More sophisticated quota tracking can be added later. - -### 5. Scope of fallback -**Decision:** Per-session, not per-agent-type (initially). -**Why:** The issue mentions per-agent-type toggle, but the simpler initial implementation -is a global fallback chain that applies to any session using a model in the chain. -Per-agent-type scoping can be added by extending the chain config with an `agentTypes` -filter. - ---- - -## Risks & Mitigations - -| Risk | Impact | Mitigation | -|------|--------|-----------| -| Model swap mid-conversation changes behavior | Medium | Log the swap, let user disable fallback | -| Different providers have different tool/feature support | High | Validate fallback model supports same API features before swapping | -| Credential resolution race conditions | Low | Use existing file-lock mechanism in auth-storage | -| Chain misconfiguration (nonexistent model) | Low | Validate chain entries on save, warn on invalid | -| Backoff timing mismatch with actual quota reset | Medium | Conservative backoff defaults; Phase 5.2 for future improvement | - ---- - -## Testing Strategy - -1. **Unit tests for FallbackResolver** — mock auth-storage and model-registry, test chain - resolution, priority ordering, backoff skipping -2. **Unit tests for extended auth-storage** — provider-level backoff tracking -3. **Integration test for retry flow** — simulate rate limit → credential fallback → - provider fallback → restoration -4. **E2E test** — configure a chain, hit rate limit on provider A, verify automatic - switch to provider B -5. **Settings tests** — validate chain CRUD operations, persistence, invalid input handling - ---- - -## Files Summary - -| File | Action | Changes | -|------|--------|---------| -| `packages/pi-coding-agent/src/core/settings-manager.ts` | Modify | Add FallbackSettings types, getters/setters | -| `packages/pi-coding-agent/src/core/auth-storage.ts` | Modify | Add provider-level backoff tracking | -| `packages/pi-coding-agent/src/core/fallback-resolver.ts` | **New** | FallbackResolver class | -| `packages/pi-coding-agent/src/core/agent-session.ts` | Modify | Integrate fallback into retry flow | -| `packages/pi-ai/src/agent.ts` | Modify | Add `setModel()` method | -| `packages/pi-coding-agent/src/cli/commands/settings.ts` | Modify | Add fallback CLI subcommands | -| `packages/pi-tui/src/` | Modify | Fallback event display | diff --git a/src/resources/extensions/google-search/index.ts b/src/resources/extensions/google-search/index.ts index 13b989ea2..a998d814f 100644 --- a/src/resources/extensions/google-search/index.ts +++ b/src/resources/extensions/google-search/index.ts @@ -68,6 +68,70 @@ async function getClient(): Promise { return client; } +/** + * Perform a search using OAuth credentials via the Cloud Code Assist API. + * This is used as a fallback when GEMINI_API_KEY is not set. + */ +async function searchWithOAuth( + query: string, + accessToken: string, + projectId: string, + signal?: AbortSignal, +): Promise { + const model = process.env.GEMINI_SEARCH_MODEL || "gemini-2.5-flash"; + const url = `https://cloudcode-pa.googleapis.com/v1internal:generateContent`; + + const response = await fetch(url, { + method: "POST", + headers: { + Authorization: `Bearer ${accessToken}`, + "Content-Type": "application/json", + "User-Agent": "google-cloud-sdk vscode_cloudshelleditor/0.1", + "X-Goog-Api-Client": "gl-node/22.17.0", + }, + body: JSON.stringify({ + project: projectId, + model, + request: { + contents: [{ parts: [{ text: query }] }], + tools: [{ googleSearch: {} }], + }, + }), + signal, + }); + + if (!response.ok) { + const errorText = await response.text(); + throw new Error(`Cloud Code Assist API error (${response.status}): ${errorText}`); + } + + const data = await response.json(); + const candidate = data.response?.candidates?.[0]; + const answer = candidate?.content?.parts?.find((p: any) => p.text)?.text ??
