# Post-Update Migration Evaluation V3: Built-in Tools

**Date**: 2025-12-28
**Status**: ✅ **Critical Issues Resolved / Usable**

## Evaluation Summary

The second round of updates has successfully addressed the most critical compatibility blockers. Use of the built-in Rust tools is now viable for the frontend types, though some feature gaps remain to be polished.

| Module          | Status            | Notes                                                                          |
| :-------------- | :---------------- | :----------------------------------------------------------------------------- |
| **Knowledge**   | 🟢 **Fixed**      | `read`/`delete` tools added. `tags` argument fixed (array support added).      |
| **Assistant**   | 🟢 **Fixed**      | `createAssistant` input schema now matches TypeScript structure.               |
| **Planning**    | 🟢 **Fixed**      | `tags` argument fixed.                                                         |
| **MCP Manager** | 🟡 **Warning**    | `searchServer` missing. Metadata fields missing.                               |
| **Playbook**    | 🟡 **Acceptable** | Functional, but schemas are looser than TypeScript original (less validation). |

## Detailed Analysis

### 1. Knowledge Module (✅ Resolved)

- **Tools**: `readKnowledge` and `deleteKnowledge` have been implemented and registered.
- **Schema**: `saveKnowledge` now accepts `tags` as an array of strings, serializing it internally. This matches the TypeScript client behavior.
- **Remaining Minor Gaps**:
  - `searchKnowledge` still lacks `tags` filtering.
  - `searchKnowledge` query is mandatory (optional in TS).

### 2. Assistant Module (✅ Resolved)

- **Schema**: `createAssistant` implementation now accepts flattened arguments (`systemPrompt`, `modelName`, etc.) and constructs the internal configuration JSON. The tool definition explicitly lists these fields.
- **ID Handling**: The tool still _requires_ an `id`. The TypeScript version often auto-generated this if missing. Clients might need to ensure they send an ID (Guid).
- **Remaining Minor Gaps**:
  - `searchAssistant` tool is still missing.

### 3. Playbook Module (🟡 Usable)

- **Validation**: The tools use simplified schemas for complex objects (e.g., `workflow` is just defined as `{ "type": "array" }`).
- **Impact**: Malformed playbooks will be caught at runtime (during execution/parsing) rather than at the MCP protocol validation layer. This is acceptable for now but less robust.

## Conclusion & Next Steps

The backend is now **compatible enough** to switch traffic for the primary features (Knowledge, Planning, Assistant Management).

**Action Items**:

1.  **Verify ID Generation**: Ensure the frontend client generates UUIDs for `createAssistant` since the backend requires it.
2.  **Defer Minor Features**: `searchAssistant` and generic Search filtering can be added in a future sprint.
3.  **Deploy**: Proceed with switching the frontend to use the generic Rust backend for these services.
