# Title: Integrate Google Search Grounding for Research Role
# Status: pending
# Dependencies: None
# Priority: medium
# Description: Update the AI service layer to enable Google Search Grounding specifically when a Google model is used in the 'research' role.
# Details:
**Goal:** Conditionally enable Google Search Grounding based on the AI role.\n\n**Implementation Plan:**\n\n1.  **Modify `ai-services-unified.js`:** Update `generateTextService`, `streamTextService`, and `generateObjectService`.\n2.  **Conditional Logic:** Inside these functions, check if `providerName === 'google'` AND `role === 'research'`.\n3.  **Construct `providerOptions`:** If the condition is met, create an options object:\n    ```javascript\n    let providerSpecificOptions = {};\n    if (providerName === 'google' && role === 'research') {\n        log('info', 'Enabling Google Search Grounding for research role.');\n        providerSpecificOptions = {\n            google: {\n                useSearchGrounding: true,\n                // Optional: Add dynamic retrieval for compatible models\n                // dynamicRetrievalConfig: { mode: 'MODE_DYNAMIC' } \n            }\n        };\n    }\n    ```\n4.  **Pass Options to SDK:** Pass `providerSpecificOptions` to the Vercel AI SDK functions (`generateText`, `streamText`, `generateObject`) via the `providerOptions` parameter:\n    ```javascript\n    const { text, ... } = await generateText({\n        // ... other params\n        providerOptions: providerSpecificOptions \n    });\n    ```\n5.  **Update `supported-models.json`:** Ensure Google models intended for research (e.g., `gemini-1.5-pro-latest`, `gemini-1.5-flash-latest`) include `'research'` in their `allowed_roles` array.\n\n**Rationale:** This approach maintains the clear separation between 'main' and 'research' roles, ensuring grounding is only activated when explicitly requested via the `--research` flag or when the research model is invoked.

# Test Strategy:
1. Configure a Google model (e.g., gemini-1.5-flash-latest) as the 'research' model in `.taskmasterconfig`.\n2. Run a command with the `--research` flag (e.g., `task-master add-task --prompt='Latest news on AI SDK 4.2' --research`).\n3. Verify logs show 'Enabling Google Search Grounding'.\n4. Check if the task output incorporates recent information.\n5. Configure the same Google model as the 'main' model.\n6. Run a command *without* the `--research` flag.\n7. Verify logs *do not* show grounding being enabled.\n8. Add unit tests to `ai-services-unified.test.js` to verify the conditional logic for adding `providerOptions`. Ensure mocks correctly simulate different roles and providers.
