10-12: LGTM! Import changes are well-organized.
The new imports are logically grouped and align with the refactoring objectives.
24-24: Verify parameter validation in create_query_engine.
The refactoring improves code organization, but we should ensure proper parameter validation.
Let's verify the parameter handling in the new function:
✅ Verification successful
Parameter validation is properly handled and top_k is preserved
The implementation in templates/components/engines/python/agent/tools/query_engine.py shows that:
- Parameters are properly validated with
params = params or {} - The
top_kfunctionality is preserved through environment variableTOP_K - The
top_kvalue is properly integrated into the params viaparams["similarity_top_k"]

Length of output: 6697
24-26: Verify the impact of removing top_k configuration.
The removal of top_k configuration might affect existing query behavior.
Let's check for existing usages and configurations:
✅ Verification successful
Based on the code inspection, I can now generate the final response:
The removal of top_k configuration is safe and handled properly
The codebase already has a robust fallback mechanism for top_k configuration:
- It's controlled via the
TOP_Kenvironment variable with a default value of 0 - When
top_kis 0 (default), the parameter is not added to the query engine - The configuration is consistently handled across different components (Python and TypeScript)

Line range hint 1-46: Overall changes look good!
The changes improve the code by making the params handling more consistent while maintaining proper error handling and streaming response functionality. The refactoring aligns well with the PR objectives.
34-35: Verify create_workflow signature changes across the codebase
The create_workflow function signature has been simplified. Let's verify that all callers have been updated to match this change.
✅ Verification successful
Let me analyze the implementation of these create_workflow functions to ensure they're consistent.
Signature changes are consistent across the codebase
The verification shows that all implementations of create_workflow are consistent with the simplified signature:
- Form filling and financial report workflows use
(chat_history: Optional[List[ChatMessage]] = None, params: Optional[Dict[str, Any]] = None) - Blog workflow uses
(chat_history: Optional[List[ChatMessage]] = None, **kwargs)and explicitly removes filters from kwargs - The caller in chat.py correctly uses the new signature with just
chat_historyandparams

1-45: Verify the impact of auto_routed mode and TOP_K changes
Please ensure that:
- The auto_routed mode is properly handled in all LlamaCloudIndex instances
- The TOP_K environment variable is consistently used across the codebase
✅ Verification successful
Auto-routed mode and TOP_K environment variable usage are consistently implemented
The verification results show:
-
LlamaCloudIndex handling is consistent:
- The auto_routed mode check is properly implemented in the query engine tool
- Other LlamaCloudIndex usages are for different purposes (file handling, index creation) and don't conflict
-
TOP_K environment variable is consistently used:
- Python: Used in chat engine, extractor engine, and query engine tools
- TypeScript: Similarly implemented in chat and workflow tools
- All implementations follow the same pattern of defaulting to 0/undefined when not set

10-10: LGTM!
The import statement is correctly placed and properly used in the refactored code.
14-15: LGTM! Improved parameter handling.
The addition of a null check and default initialization for params improves robustness.
29-29: LGTM! Corrected return type annotation.
The removal of the incorrect return type annotation QueryEngineTool is appropriate since the function returns a list of tools, not a single tool.
21-25: Verify the get_query_engine_tool implementation.
The refactoring to use get_query_engine_tool looks good, but let's verify its implementation to ensure it handles the engine parameters correctly.
✅ Verification successful
Let me gather more information about the implementation details of get_query_engine_tool and its usage.
Let me check the implementation of create_query_engine since it's a crucial part of the get_query_engine_tool function.
Implementation of get_query_engine_tool is correct and properly handles engine parameters
The implementation is well-structured and handles engine parameters appropriately:
- Correctly accepts optional engine parameters and passes them to
create_query_engine create_query_engineproperly merges environment configurations (TOP_K) with provided parameters- Special handling for LlamaCloudIndex with auto-routing
- Consistent usage across multiple agents (blog, financial_report, form_filling) with similar parameter patterns

Line range hint 58-350: LGTM! Verify integration with new changes.
The workflow implementation looks good and integrates well with the refactored code. The assertions in FinancialReportWorkflow.__init__ properly validate the tools created by the new _create_query_engine_tool function.
Let's verify the workflow usage:
✅ Verification successful
Integration with workflow factory is properly maintained
The workflow implementation integrates correctly with the factory code. The create_workflow function properly uses the _create_query_engine_tool function and passes the created tools to the FinancialReportWorkflow constructor, which matches the assertions and requirements defined in the workflow class.

3-6: Add JSDoc comments to document the new params structure.To help users migrate from the old API and understand the expected params structure, consider adding documentation.
Add JSDoc comments above the function:
+ /** + * Creates a chat engine instance + * @param params - Configuration parameters for the chat engine + * @param params.documentIds - Optional array of document IDs to include in the chat context + * // Document other parameters + * @returns A SimpleChatEngine instance + */ export async function createChatEngine(params?: ChatEngineParams) {templates/components/engines/typescript/agent/tools/query-engine.ts (2)
8-12: Consider replacing 'any' with specific types for better type safety.The
paramsandmetadataparameters are typed asany, which bypasses TypeScript's type checking benefits.Consider defining specific interfaces:
interface QueryEngineParams { // Add specific parameters similarityTopK?: number; retriever_mode?: string; } interface QueryEngineMetadata { name?: string; description?: string; // Add other metadata fields } export function createQueryEngineTool( index: VectorStoreIndex | LlamaCloudIndex, params?: QueryEngineParams, metadata?: QueryEngineMetadata ): QueryEngineTool
15-19: Enhance the tool description for better clarity.The current description is generic and could be more informative about the tool's capabilities and expected usage.
Consider a more detailed description:
- description: `Use this tool to retrieve information about the text corpus from an index.`, + description: `Use this tool to search and retrieve relevant information from the indexed documents. The tool performs semantic search and returns the most relevant content based on the query.`,templates/types/streaming/express/src/controllers/chat.controller.ts (1)
Line range hint
15-70: Consider enhancing error handling granularityThe current error handling catches all errors in a single try-catch block. Consider separating the error handling for different operations (engine creation, streaming, question generation) to provide more specific error messages and appropriate status codes.
Consider restructuring the error handling:
- Separate try-catch blocks for engine creation and streaming
- Add specific error types for different failure scenarios
- Map different error types to appropriate HTTP status codes
Example structure:
try { const chatEngine = await createChatEngine(engineParams); } catch (error) { if (error instanceof EngineInitializationError) { return res.status(503).json({ detail: "Chat engine initialization failed", error: error.message, }); } throw error; // Let the outer catch handle unknown errors }templates/types/streaming/nextjs/app/api/chat/route.ts (1)
41-46: Consider adding type safety and validationThe new approach with
engineParamsis clean and flexible. However, consider these improvements:
- Add type safety for the
engineParamsobject- Validate the
dataobject before spreading to prevent overridingpreFilters- Add error handling for invalid filter generation
Consider applying this type-safe approach:
interface EngineParams { preFilters: ReturnType<typeof generateFilters>; [key: string]: any; // for additional params } const engineParams: EngineParams = { preFilters: generateFilters(ids), ...(data || {}), // ensure data exists };templates/components/agents/typescript/form_filling/workflow/form-filling.ts (3)
195-196: Enhance error message for unknown toolThe error message could be more descriptive to help with debugging.
Consider this improvement:
- throw new Error(`Unknown tool: ${toolName}`); + throw new Error(`Unknown tool: ${toolName}. Expected one of: ${[ + this.extractorTool.metadata.name, + this.fillMissingCellsTool.metadata.name, + this.queryEngineTool?.metadata.name + ].filter(Boolean).join(', ')}`);Also applies to: 203-203
235-236: Enhance error message for missing query engine toolThe error message could be more descriptive to help with debugging.
Consider this improvement:
- throw new Error("Query engine tool is not available"); + throw new Error("Query engine tool is not available. This is required for the FindAnswers operation.");
51-51: Consider future extensibility requirementsThe change from an array of tools to a single tool might limit future extensibility if multiple query engines are needed. Consider documenting the reasoning behind this architectural decision and any potential future considerations.

4-4: LGTM: Import statement aligns with single tool architecture
The change from getQueryEngineTools to getQueryEngineTool correctly reflects the architectural shift to using a single query engine tool.
14-14: 🛠️ Refactor suggestion
Consider adding runtime checks instead of non-null assertion
While the non-null assertion operator (!) is consistent with other tool assignments, it could mask potential runtime errors if getQueryEngineTool() returns undefined. Consider adding explicit error handling:
- queryEngineTool: (await getQueryEngineTool())!,
+ queryEngineTool: await getQueryEngineTool() ??
+ throw new Error("Failed to initialize query engine tool"),Let's verify the FormFillingWorkflow's compatibility with this change:

Line range hint 14-18: Verify consistent tool initialization pattern
Let's verify that the single tool initialization pattern is consistently applied across the codebase.
✅ Verification successful
Tool initialization patterns are consistently applied across workflows
The verification shows that tool initialization patterns are consistently applied across the codebase:
- All workflow factories use
getTool()for specific tools (e.g., "interpreter", "document_generator", "extract_missing_cells") getQueryEngineTool()is consistently used for query engine initialization in all workflows (FormFillingWorkflow, FinancialReportWorkflow, and blog workflow)- The initialization pattern follows the same structure in all workflow constructors with tools being properly awaited and type-asserted

28-33: 🛠️ Refactor suggestion
Consider adding type safety and validation for engine parameters
The current implementation has several areas for improvement:
- Spreading raw request data (
...data) directly into engine parameters could expose security vulnerabilities if not properly validated - The
engineParamsobject lacks type definition - No validation is performed on the properties from
data
Consider applying these improvements:
+ interface EngineParams {
+ preFilters: Record<string, unknown>;
+ // Add other expected parameters
+ }
- const engineParams = {
+ const engineParams: EngineParams = {
preFilters: generateFilters(ids),
- ...data,
+ ...validateEngineParams(data), // Add validation function
};Let's check how engineParams is used across the codebase:
templates/types/streaming/nextjs/app/api/chat/route.ts (1)

The refactoring of query engine tool usage was properly isolated to the relevant code sections, maintaining the integrity of other agent creation functions.
Line range hint 1-124: Verify auto_routed mode implementation.
The PR title mentions "use auto_routed mode for LlamaCloudIndex" but there are no explicit changes for this in the current file.
✅ Verification successful
Auto-routed mode is properly implemented
The auto_routed mode is correctly implemented in both TypeScript and Python query engine tools, and it's properly integrated into the agents through the imported getQueryEngineTool. The mode is automatically enabled when using LlamaCloudIndex:
- In
templates/components/engines/typescript/agent/tools/query-engine.ts: Setsretriever_mode = "auto_routed"for LlamaCloudIndex - In
templates/components/engines/python/agent/tools/query_engine.py: Setsauto_routed = Truefor LlamaCloudIndex

8-13: Verify tools array initialization edge case.
The tools array is filtered for undefined values, which could potentially result in an empty array if all tool initializations fail.
✅ Verification successful
Let me check the surrounding context of the error handling found to ensure it's properly handling the empty tools case.
Let me check how this tools array is used in the agent creation to ensure proper handling.
Let me check the implementation of FunctionCallingAgent in the single-agent file since it's imported.
Based on the gathered evidence, I can now provide the final response:
Empty tools array is properly handled in the system
The codebase has appropriate handling for empty tools array:
- The helpers (typescript.ts and python.ts) explicitly check for empty tools and switch to a chat engine when needed
- The researcher agent's tools array is filtered for undefined values and passed directly to FunctionCallingAgent
- Other agents like the publisher can work with empty tools array (as seen in
tools: tool ? [tool] : [])

13-15: Verify the impact of adding 'or' condition
The addition of condition: "or" makes the return structure consistent across both cases. However, we should verify that this change doesn't affect existing query behavior.
✅ Verification successful
Let me gather more information about the filter implementation across different files to understand the impact better.
Let me try a different approach to check the filter implementations.
Adding 'or' condition is correct and maintains consistency
The addition of condition: "or" in the no-documentIds case for LlamaCloud's implementation is correct and safe. Here's why:
- In Weaviate's implementation, the no-documentIds case only returns
{ filters: [publicDocumentsFilter] }which is less consistent - In both implementations, when documentIds are provided, they use
condition: "or"to combine public and private document filters - The LlamaCloud change makes the filter structure consistent regardless of whether documentIds are provided
- This change won't affect the query behavior since there's only one filter in the array, making the "or" condition redundant but harmless

48-48: LGTM: Property type declaration is correct
The property type declaration for queryEngineTool correctly reflects the transition to a single tool instance.
56-56: LGTM: Constructor parameter and initialization are consistent
The constructor parameter type and property initialization correctly implement the single tool approach.
Also applies to: 73-73
219-219: Consider refactoring callTools to accept a single tool
Since we're transitioning to a single tool approach, consider modifying the callTools function to accept a single tool instead of an array. This would make the API more explicit and avoid unnecessary array creation.
Let's verify the usage of callTools across the codebase:

✅ Verification successful
Based on the search results, I can now generate the final response:
Migration to single tool approach is complete
The codebase has been fully migrated to use single tool instances. Specifically in the financial report workflow:
- All tool declarations are single instances (
queryEngineTool,codeInterpreterTool,documentGeneratorTool) - Tool usage in
handleLLMInput,handleResearch,handleAnalyze, andhandleReportGenerationmethods consistently uses single tool instances - No array-based tool declarations or operations found in the codebase

4-4: LGTM: Import change aligns with auto_routed mode transition
The change from importing getQueryEngineTools to getQueryEngineTool correctly reflects the transition to using a single auto-routed query engine tool.
21-23: Verify FormFillingWorkflow class compatibility
The changes to use a single queryEngineTool look good, but we should verify that the FormFillingWorkflow class has been updated to handle these parameter changes.
✅ Verification successful
Let me gather more information about the constructor and usage of the FormFillingWorkflow class.
FormFillingWorkflow class is compatible with the changes
The FormFillingWorkflow class constructor is already set up to handle the optional queryEngineTool parameter, as evidenced by the type definition queryEngineTool?: BaseToolWithCall in both the class properties and constructor parameters. The changes in the factory align perfectly with the existing workflow implementation.
