templates/types/reflex/app/services/file.py (4)
28-43: Pydantic Model Fields
DocumentFileis clear and concise. However, consider providing default values for optional fields liketype,size, orurlto ensure that any omitted fields are handled gracefully when constructing an instance.
100-176: Exception Handling & File Naming
Whilesave_filerobustly handles I/O exceptions, catching a broadExceptionat lines 147–149 might make debugging harder if there are other error categories (e.g., memory errors). Consider narrowing the exception scope or re-throwing after logging to preserve the traceback.
211-229: Vector Store Index Ingestion
The ingestion pipeline approach makes sense. If concurrency or heavy parallel ingestion is expected at scale, consider further concurrency management or queue management to avoid potential data race conditions when persisting the index.
230-255: Integration with LlamaCloud
The usage ofLLamaCloudFileServiceappears straightforward. Consider clarifying in docstrings any potential latency or rate-limiting issues if a large number of files are uploaded rapidly to LlamaCloud.templates/types/reflex/app/api/routers/models.py (1)
33-62: URL Extraction Logic
The multi-branch logic for deriving theurlfrom metadata is clear. However, consider adding fallback behaviors or explicit error messages if the file name is present but no recognized scenario (private file, LlamaCloud, local data) applies. This would help diagnose unexpected states quickly.questions/questions.ts (2)
103-121: Use Case Selection Prompt
Asking about “Structured Extractor” vs. “Contract review” is well-defined. Consider clarifying any difference in system requirements for each use case or referencing docs to help users make an informed choice.
376-379: Reflex Template and LlamaParse
This comment clarifies that Reflex doesn’t support LlamaParse. If future changes remove that limitation, remember to update prompt logic to align with the new capabilities.

1-22: Imports and logging
Imports and constants are well-organized; using logger is a good practice for centralized logging.
49-99: Conditional CSV Handling & Indexing
The CSV skip branch avoids indexing CSV files, which is fine if this is intentional. Be mindful that any future logic changes for CSV handling (like partial indexing or some transformation) would require adjusting this condition.
177-210: Base64 Preprocessing & Document Loading
_preprocess_base64_file: Be mindful of edge cases (e.g., missing comma inbase64_contentor an unrecognized MIME type)._load_file_to_documents: Good fallback logic for file readers. Ensuring extension-based dispatch is correct and consistent can help avoid confusion if new file formats are added.
257-281: Name Sanitization & Parsing Logic
_sanitize_file_name: Substituting all non-alphanumeric characters with_is a sensible approach to prevent file system issues._get_llamaparse_parserand_default_file_loaders_map: Providing plugin-like extension points for different parsers is a nice design choice for future maintenance and feature growth.
templates/types/reflex/app/api/routers/models.py (2)
13-19: SourceNodes Model
The SourceNodes class is well-structured. Using Optional[float] for score is appropriate, and referencing Dict[str, Any] for metadata allows flexibility.
20-32: from_source_node Method
Extracting metadata to populate SourceNodes is concise. Verify that all relevant fields in NodeWithScore (like node’s annotation or extra metadata) are not lost during this transformation if they’re needed elsewhere.

e2e/utils.ts (2)
36-36: Add JSDoc for new property
Consider documenting the purpose of the optionaluseCaseproperty inRunCreateLlamaOptionsto clarify for other developers how it should be used.
116-117: Maintain future extensibility
The condition checking for(templateType === "multiagent" || templateType === "reflex")may expand in the future to new template types. Consider extracting the logic to handleuseCasedynamically, without repeating conditions, so new template types automatically support--use-case.questions/simple.ts (2)
171-171: Allow for future custom useCase expansions
"form_filling"is a straightforward option. If you anticipate broader categories, consider storing these useCase strings in an external config or enum for easier scaling.
179-179: Assess necessity of additional tools
Given"extractor"use case, confirm whether additional extraction libraries or parsing utilities might be beneficial to automate structured data extraction.index.ts (1)
205-208: Clarify usage instructions in CLI help
The newly introduced--use-case <useCase>option is documented well, but consider clarifying whether it applies only to certain template types (like multiagent or reflex) to guide CLI users.helpers/typescript.ts (2)
134-138: Improve error messages & future-proofing
You’re adding logic to copy additional files based onuseCase. It might be beneficial to check if the specifieduseCaseactually exists undercompPath/agents/typescript/and provide a clear error if it doesn't.
140-143: Add robust file handling
The additional copy step here is crucial for injecting useCase-specific files. Consider robust error handling (e.g., try/catch) to help debug cases where source folders may be missing.helpers/python.ts (1)
Line range hint
484-498: Conditional check for multiagent/reflex and the newuseCaseparameter.These lines handle template-specific logic for “multiagent” or “reflex.” The
useCaseparameter is checked to determine which folder is copied. If nouseCaseis provided, the process exits early with an error. This design helps ensure that at least one viable workflow is selected. However, it might be helpful to provide clearer messaging or fallback logic if an unsupporteduseCaseis passed in.questions/questions.ts (2)
230-235: Forcing “fastapi” and customizing data sources in Reflex.Line 232 forcibly sets
program.framework = "fastapi". This ensures consistency in the code path for reflex apps. However, if later expansions allow other frameworks with Reflex, this may become overly restrictive.
393-393: Blocking LlamaParse usage in Reflex.Reflex doesn’t support LlamaParse (due to its asyncio constraints). This guard line ensures that the user isn’t asked about LlamaParse. If Reflex is extended to handle asynchronous logic in future, remember to remove or revise this check.

e2e/shared/reflex_template.spec.ts (4)
6-6: Confirm import alignment with updated types.
Importing TemplateUseCase indicates a transition from agents to use cases. Please ensure all references in related files are similarly updated to maintain a consistent, error-free import environment.
15-15: Use of explicit type array is clear.
Declaring templateUseCases as TemplateUseCase[] = ["extractor", "contract_review"] is straightforward. This explicit typing aligns with the newly introduced TemplateUseCase type while avoiding confusion with the prior TemplateAgents.
23-24: Iterate over newly introduced useCase consistently.
Replacing templateAgents with templateUseCases here properly reflects the new domain logic. Ensure all associated references (test names, logs, etc.) are consistently updated to reflect “useCase” to avoid confusion.
42-42: Check triaging for new useCase parameter.
Passing useCase to runCreateLlama is now crucial. Verify that any new logic in runCreateLlama does not require additional parameters or validations.
If needed, consider centralizing useCase validations or enumerations in one place to maintain code clarity.
helpers/types.ts (2)
52-52: New type introduction complements the rename.
TemplateUseCase enumerates typical uses (financial report, blog, etc.) effectively. This type clarifies domain-specific options previously represented by TemplateAgents.
109-109: Renaming 'agents' to 'useCase' in the install args is consistent.
This helps maintain a common conceptual thread across the codebase, especially given the domain shift from multiagent logic to singular use-case logic.
e2e/shared/multiagent_template.spec.ts (4)
21-21: Const array rename aligns with the domain shift.
const templateUseCases = [...] effectively supersedes templateAgents. This rename fosters consistency across all test files referencing multiagent or multi-use-case flows.
23-24: Loop variable reflects the new domain concept “useCase”.
Switching from agents to useCase in the loop iteration helps unify usage patterns around the newly introduced domain concept.
49-49: Passing 'useCase' into runCreateLlama.
Ensuring that runCreateLlama supports the new useCase parameter prevents any regression in the previously agent-based code paths.
74-75: Skip logic references updated 'useCase'.
Modifying the skip conditions to evaluate useCase is consistent with this domain change. Double-check if existing test coverage remains adequate, especially for newly introduced or renamed cases.
create-app.ts (2)
42-42: Parameter rename 'useCase' aligns with updated domain.
createApp adopting useCase instead of agents maintains clarity in parameter naming. Confirm that all internal references and downstream calls handle this new property name properly.
87-87: Propagate 'useCase' into installTemplate arguments.
Including useCase in the args object ensures the new field is correctly passed to the installation logic. Double-check that any logic inside installTemplate or subsequent calls is prepared for useCase.
e2e/utils.ts (1)
54-54: Ensure consistent naming across entire codebase
Renaming parameters from agents to useCase is self-explanatory, but be sure that all references (including docs, comments, and variable names) are updated to avoid confusion.
questions/simple.ts (3)
136-136: Excellent alignment with broader terminology shift
Replacing "agents" with "useCase" in the type definition clarifies usage. The code here seems consistent with the new mental model.
163-163: Check for potential domain-specific logic
Hardcoding 'financial_report' ties the code to a specific scenario. If more complex finance use cases arise, you may benefit from dynamic generation or configuration of these strings.
186-186: Confirm multi-step or single-step usage
"contract_review" may involve multiple steps (e.g., summarizing, highlighting, redlining). Ensure that the single useCase—"contract_review"—covers all business needs.
helpers/typescript.ts (1)
29-29: Ensure parameter consistency
In InstallTemplateArgs, confirm that useCase is optional or required, and ensure consistent usage across Python, TypeScript, and any new frameworks so the code remains uniform.
helpers/python.ts (1)
383-407: Expanded function signature for installPythonTemplate.
Lines 383–407 introduce additional parameters (appName, postInstallAction, modelConfig, useCase, etc.) to installPythonTemplate and replace the old agents concept with useCase. This shift to a more explicit "use case" parameter improves clarity on what functionality is being built. Make sure to update all call sites to provide the appropriate arguments. Also confirm that the previously optional parameter agents has been fully removed or deprecated across the codebase to keep usage consistent.
questions/questions.ts (5)
5-5: New data source imports for Reflex support.
Importing EXAMPLE_FILE and EXAMPLE_GDPR expands data source options for reflex use cases. These constants look fine. Ensure that changes in data source usage are also reflected in associated test cases.
36-36: Added “Fullstack python template with Reflex” option.
This new option helps direct users to the Python + Reflex template. No issues noted.
103-120: Prompting for Reflex use case selection.
This block automatically sets framework = "fastapi" and requires answering a new prompt for the reflex use case, defaulting data sources to [EXAMPLE_FILE]. This flow matches the introduced changes in installPythonTemplate. Carefully verify whether the user needs an option to skip or configure additional data sources, especially if “extractor” is too specific.
192-228: Shared prompt logic for “reflex” or “multiagent.”
This conditional re-prompts for a useCase if the user didn’t specify one earlier. It’s a good fallback for coverage, but note that lines 202–203 refer to “Contract review (using Workflow),” which is repeated above. Confirm you aren’t prompting duplicates or overriding prior choices.
261-262: Ensuring example data for LlamaCloud with no sources.
The fallback logic sets default data sources if vectorDb === "llamacloud" and none are provided. This is a convenient approach to avoid empty indexes. Verify it doesn’t conflict with earlier setting of [EXAMPLE_FILE] for reflex.

93-104: Enhance LlamaCloud API key handling.Consider these improvements for better user experience:
- Validate the API key format
- Explicitly inform users when falling back to environment variable
- Handle the case when both direct input and environment variable are missing

163-163: Add type safety for use case values.The lookup object correctly maps use cases to configurations, but we can improve type safety.
Add a type definition for allowed use case values:
type UseCase = 'financial_report' | 'form_filling' | 'extractor' | 'contract_review'; // Then update the Record type to enforce valid use case values: type LookupType = Record< AppType, Pick<QuestionResults, "template" | "tools" | "frontend" | "dataSources"> & { useCase?: UseCase; modelConfig?: ModelConfig; } >;Also applies to: 171-171, 179-179, 186-186

79-91: Well-implemented LlamaCloud services prompt!
The toggle prompt provides a clean user experience with good defaults and helpful documentation link.
136-136: Verify the type change impact across the codebase.
The change from agents to useCase in the type definition reflects an architectural shift. Let's verify all related changes are consistent.
✅ Verification successful
Let me try a different search strategy to verify the type changes.
Let me try one more time with a simpler search approach.
Type change from 'agents' to 'useCase' appears consistent across the codebase
Based on the search results, the change appears to be consistent. The QuestionResults type is used across multiple files (simple.ts, utils.ts, index.ts, types.ts, ci.ts), and there are no remaining references to 'agents' in the type definition or its usage. The new 'useCase' field in the type Pick is aligned with the codebase's current state.
