responseBody rejects a valid producer result containing 65,536 astral characters, because Schema.isMaxLength(65_536) counts UTF-16 code units while the desktop producer truncates with Array.from(...).slice(0, 65_536), which counts code points. Align the producer's truncation with String.length (and the other bounded diagnostic fields) or use schema bounds with matching code-point semantics.

preview_diagnostics cannot return diagnostics: every MCP invocation is routed to a host that advertises diagnostics, but PreviewAutomationHosts.tsx has no case "diagnostics", so the request completes with undefined instead of calling PreviewManager.automationDiagnostics. Add the host switch case and the corresponding IPC/preload automationDiagnostics bridge.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Bound diagnostic text by UTF-16 length, not code points.
boundedDiagnosticText slices by code points (Array.from). The contract bounds use Schema.isMaxLength, which counts UTF-16 code units. For text that contains astral characters (for example emoji), 65,536 code points can produce up to 131,072 code units. The encoded responseBody then fails PreviewAutomationNetworkDiagnosticsResult validation, and the diagnostics tool call returns an error instead of a truncated body. url (2,048) and errorText (4,096) have the same mismatch.
Slice by string length so the produced values always satisfy the contract bounds.
🐛 Proposed fix
-const boundedDiagnosticText = (value: unknown, limit: number): string =>
- Array.from(String(value)).slice(0, limit).join("");
+const boundedDiagnosticText = (value: unknown, limit: number): string => {
+ const text = String(value);
+ // Schema bounds count UTF-16 code units, so slice the same way.
+ return text.length > limit ? text.slice(0, limit) : text;
+};Update the truncation flag at line 4068 to match:
- responseBodyTruncated: Array.from(body).length > DIAGNOSTIC_RESPONSE_BODY_LIMIT,
+ responseBodyTruncated: body.length > DIAGNOSTIC_RESPONSE_BODY_LIMIT,📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
