* enhancement: Add URL format hint to Base URL field (#593)
Add dynamic provider-specific format examples to Base URL field labels to clarify expected URL format. Includes missing defaultBaseUrl values for providers.
* fix: Use generic example URL instead of OpenAI URL for fallback
* [Feature] Add VLM-based diagram validation
Add automatic VLM (Vision Language Model) validation after display_diagram
tool execution. The system captures a screenshot of the rendered diagram,
sends it to a VLM for visual analysis, and uses feedback to improve
diagram quality through the existing retry mechanism.
Changes:
- Add /api/validate-diagram endpoint for VLM validation
- Add diagram-validator.ts for client-side validation orchestration
- Add validation-prompts.ts for VLM system prompts
- Add ValidationCard component to display validation status in chat
- Add PNG capture functionality to diagram context
- Integrate validation into tool handlers with retry support (max 3)
- Add "Improve with Suggestions" button for manual regeneration
- Add settings toggle to enable/disable VLM validation
- Add getValidationModel() helper in ai-providers.ts
* refactor(validation): use AI SDK structured outputs and address review feedback
- Replace generateText + manual JSON parsing with generateObject and Zod schema
for type-safe structured validation output
- Use AbortSignal.timeout() instead of Promise.race for cleaner timeout handling
- Add timeout validation with minimum 1000ms to handle malformed env values
- Remove unused xml parameter from validateRenderedDiagram API
- Remove parseValidationResponse function (now handled by schema)
- Clear validationStates on session switch and new chat to prevent memory leak
- Update 100ms render delay comment to clarify best-effort heuristic
- Remove unused useEffect import from ValidationCard
- Fix optional chaining lint warning in ValidationCard
- Add unit tests for formatValidationFeedback function
* refactor(validation): use AI SDK experimental_useObject hook instead of raw fetch
- Change API endpoint from generateObject to streamObject for useObject compatibility
- Create useValidateDiagram hook using AI SDK's experimental_useObject for reactive validation
- Update useDiagramToolHandlers to accept validation function as parameter
- Update chat-panel to use new useValidateDiagram hook
- Remove validateRenderedDiagram function from lib/diagram-validator.ts (now in hook)
- Export ValidationResultSchema from API route for client-side use
* fix(validation): extract schema to shared file for client/server compatibility
Move ValidationResultSchema to lib/validation-schema.ts to avoid importing
server-side modules (ai-providers) into client-side code. This fixes the
Turbopack build error caused by the hook importing from the API route.
* fix(validation): use 'Valid' instead of 'Complete' for validation success
Change ValidationCard success label from 'Complete' to 'Valid' to avoid
conflicting with ToolCallCard's 'Complete' badge in E2E tests. This fixes
the diagram-generation E2E test that expects a specific count of 'Complete'
badges.
* fix(validation): add aria-hidden to icons to prevent duplicate ID warning
* fix: improve VLM validation with bug fixes and i18n
- Fix race condition in pendingValidationRef (reject previous pending validation)
- Fix response format consistency (use streaming for all responses)
- Remove dead code (unused lastRequestRef and ValidationRequest interface)
- Consolidate duplicate types (re-export from validation-schema.ts)
- Add 'success_with_warnings' status for valid diagrams with warnings
- Fix tool card auto-collapse (only collapse once, respect user toggle)
- Set VLM validation default to disabled
- Add i18n support for diagram validation settings (en/zh/ja)
- Mark feature as experimental in settings UI
* fix: resolve TypeScript errors in electron-standalone
- Add forwardRef support to ChatInput component with ChatInputRef type
- Copy electron.d.ts to electron-standalone/electron folder
- Exclude electron-standalone from root tsconfig type checking

- Add validation section to en.json, zh.json, ja.json dictionaries
- Update ValidationCard to use useDictionary hook
- Replace all hardcoded English strings with i18n keys

* Modernize Input Field Scrollbar Design #536
* Added Input Field Scrollbar Design #536
* The edit mode for the user scroller already looks good, so there’s no need to change it. The scrollbar-thin class only makes the scrollbar smaller compared to when it’s not present, so it isn’t needed.

PR #442 accidentally changed showSaveDialog from using the diagram
context to local state, breaking draw.io's native save button (Ctrl+S)
that was fixed in PR #296.
This restores the original behavior by using the context's showSaveDialog
so both draw.io native save and the download button open the same dialog.
