- Implement retry logic with exponential backoff (max 2 retries) to handle transient failures
- Add 5-second fetch timeout to prevent hanging on unreachable backends
- Improve error logging with clear messages about config fetch status
- Always return DeerFlowConfig (never null) to prevent UI rendering issues
- Add safety checks in input-box component to verify reasoning models before access
- Improve type safety: verify array length before accessing array indices
- Add comprehensive documentation in .env.example with examples for different deployment scenarios
- Document NEXT_PUBLIC_API_URL variable behavior and fallback mechanism
* Apply suggestions from code review

- Backend: Convert non-string content (lists, dicts) to JSON strings in _create_event_stream_message to ensure frontend always receives string content
- Frontend: Add type guard before calling startsWith() on toolCall.result for defensive programming
This fixes the TypeError: toolCall.result.startsWith is not a function when tools return complex objects.
Fixes#570 where browser freezes when research plan has 8+ steps.
Performance optimizations:
- Add animation throttling: only animate first 10 activity items
- Reduce animation durations (0.4s → 0.3s for activities, 0.2s → 0.15s for results)
- Remove scale animations (GPU-intensive) from search results
- Limit displayed results (20 pages, 10 images max)
- Add conditional animations based on item index
- Cap animation delays to prevent excessive staggering
- Add React.memo to ActivityMessage and ActivityListItem components
These changes significantly improve performance when rendering multiple
research steps while maintaining visual appeal for smaller lists.
* fix: prevent repeated content animation during thinking streaming (#614)
- Implement chunked rendering using reasoningContentChunks
- Static content (previous chunks) renders without animation
- Only current streaming chunk animates
- Disable animation on plan content (title, thought, steps) during streaming
- Animation applies after content finishes streaming (when complete)
- Prevents visual duplication of repeated sentences in thinking process
- Changed key from question text to combination of index and question text
- Ensures unique keys even if translation has duplicate questions
- Resolves React warning: 'Each child in a list should have a unique key prop'
* fix: support local models by making thought field optional in Plan model
- Make thought field optional in Plan model to fix Pydantic validation errors with local models
- Add Ollama configuration example to conf.yaml.example
- Update documentation to include local model support
- Improve planner prompt with better JSON format requirements
Fixes local model integration issues where models like qwen3:14b would fail
due to missing thought field in JSON output.
* feat: Add intelligent clarification feature for research queries
- Add multi-turn clarification process to refine vague research questions
- Implement three-dimension clarification standard (Tech/App, Focus, Scope)
- Add clarification state management in coordinator node
- Update coordinator prompt with detailed clarification guidelines
- Add UI settings to enable/disable clarification feature (disabled by default)
- Update workflow to handle clarification rounds recursively
- Add comprehensive test coverage for clarification functionality
- Update documentation with clarification feature usage guide
Key components:
- src/graph/nodes.py: Core clarification logic and state management
- src/prompts/coordinator.md: Detailed clarification guidelines
- src/workflow.py: Recursive clarification handling
- web/: UI settings integration
- tests/: Comprehensive test coverage
- docs/: Updated configuration guide
* fix: Improve clarification conversation continuity
- Add comprehensive conversation history to clarification context
- Include previous exchanges summary in system messages
- Add explicit guidelines for continuing rounds in coordinator prompt
- Prevent LLM from starting new topics during clarification
- Ensure topic continuity across clarification rounds
Fixes issue where LLM would restart clarification instead of building upon previous exchanges.
* fix: Add conversation history to clarification context
* fix: resolve clarification feature message to planer, prompt, test issues
- Optimize coordinator.md prompt template for better clarification flow
- Simplify final message sent to planner after clarification
- Fix API key assertion issues in test_search.py
* fix: Add configurable max_clarification_rounds and comprehensive tests
- Add max_clarification_rounds parameter for external configuration
- Add comprehensive test cases for clarification feature in test_app.py
- Fixes issues found during interactive mode testing where:
- Recursive call failed due to missing initial_state parameter
- Clarification exited prematurely at max rounds
- Incorrect logging of max rounds reached
* Move clarification tests to test_nodes.py and add max_clarification_rounds to zh.json
