* fix:update the code with review comments
* fix: Add runtime parameter to compress_messages method(#803)
* fix: Add runtime parameter to compress_messages method(#803)
The compress_messages method was being called by PreModelHookMiddleware
with both state and runtime parameters, but only accepted state parameter.
This caused a TypeError when the middleware executed the pre_model_hook.
Added optional runtime parameter to compress_messages signature to match
the expected interface while maintaining backward compatibility.

* fix: address Copilot review comments for coordinator_node - Extract locale from direct_response tool_args - Fix import sorting (ruff I001)
* fix: remove locale extraction from tool_args in direct_response
Use locale from state instead of tool_args to avoid potential side effects. The locale is already properly passed from frontend via state.
* fix: only fallback to planner when clarification is enabled
In legacy mode (BRANCH 1), no tool calls should end the workflow gracefully instead of falling back to planner. This fixes the test_coordinator_node_no_tool_calls integration test.

Add a new "analysis" step type to handle reasoning and synthesis tasks
that don't require code execution, addressing the concern that routing
all non-search tasks to the coder agent was inappropriate.
Changes:
- Add ANALYSIS enum value to StepType in planner_model.py
- Create analyst_node for pure LLM reasoning without tools
- Update graph routing to route analysis steps to analyst agent
- Add analyst agent to AGENT_LLM_MAP configuration
- Create analyst prompts (English and Chinese)
- Update planner prompts with guidance on choosing between
analysis (reasoning/synthesis) and processing (code execution)
- Change default step_type inference from "processing" to "analysis"
when need_search=false

* fix: ensure researcher agent uses web search tool instead of generating URLs (#702)
- Add enforce_researcher_search configuration option (default: True) to control web search requirement
- Strengthen researcher prompts in both English and Chinese with explicit instructions to use web_search tool
- Implement validate_web_search_usage function to detect if web search tool was used during research
- Add validation logic that warns when researcher doesn't use web search tool
- Enhance logging for web search tools with special markers for easy tracking
- Skip validation during unit tests to avoid test failures
- Update _execute_agent_step to accept config parameter for proper configuration access
This addresses issue #702 where the researcher agent was generating URLs on its own instead of using the web search tool.
* fix: addressed the code review comment
* fix the unit test error and update the code
* fix: resolve issue #650 - repair missing step_type fields in Plan validation
- Add step_type repair logic to validate_and_fix_plan() to auto-infer missing step_type
- Infer as 'research' when need_search=true, 'processing' when need_search=false
- Add explicit CRITICAL REQUIREMENT section to planner.md emphasizing step_type mandatory for every step
- Include validation checklist and examples showing both research and processing steps
- Add 23 comprehensive unit tests for validate_and_fix_plan() covering all scenarios
- Add 4 integration tests specifically for Issue #650 with actual Plan validation
- Prevents Pydantic ValidationError: 'Field required' for missing step_type

* feat: Add comprehensive Chinese localization support for issue #412
- Add locale parameter to ChatRequest model to capture user's language preference
- Implement language-aware template loading in template.py with fallback to English
- Update all apply_prompt_template calls to pass locale through the workflow
- Create Chinese translations for 14 core prompt files:
* Main agents: coordinator, planner, researcher, reporter, coder
* Subprocess agents: podcast_script_writer, ppt_composer, prompt_enhancer
* Writing assistant: all 6 prose prompts
- Update app.py to extract and propagate locale through workflow state
- Support both zh-CN and en-US locales with automatic fallback
- Ensure locale flows through all agent nodes and template rendering
* address the review suggestions
* fix: ensure web search is performed for research plans to fix#535
When using certain models (DeepSeek-V3, Qwen3, or local deployments), the
agent framework failed to trigger web search tools, resulting in hallucinated
data. This fix implements multiple safeguards:
1. Add enforce_web_search configuration flag:
- New config option to mandate web search in research plans
- Defaults to False for backward compatibility
2. Add plan validation function validate_and_fix_plan():
- Validates that plans include at least one research step with web search
- Enforces web search requirement when enabled
- Adds default research step if plan has no steps
3. Enhance coordinator_node fallback logic:
- When model fails to call tools, fallback to planner instead of __end__
- Ensures workflow continues even when tool calling fails
- Logs detailed diagnostic info for debugging
4. Update prompts for stricter requirements:
- planner.md: Add MANDATORY web search requirement and clear warnings
- coordinator.md: Add CRITICAL tool calling requirement
- Emphasize consequences of missing web search (hallucinated data)
5. Update tests to reflect new behavior:
- test_coordinator_node_no_tool_calls: Expect planner instead of __end__
- test_coordinator_empty_llm_response_corner_case: Same expectation
Fixes#535 by ensuring:
- Web search is always performed for research tasks
- Workflow doesn't terminate on tool calling failures
- Models with poor tool calling support can still proceed
- No hallucinated data without real information gathering
