52-82: Fix event loop blocking: async endpoint calling sync I/O.The endpoint is
async def(required forawait validate_csv_file), but line 72 calls the synchronousupload_datasetservice, which performs blocking I/O operations (database queries, Langfuse API calls, object store uploads). This blocks FastAPI's event loop and degrades concurrency.🔎 Recommended fixes (choose one):
Option 1 (simplest): Run the sync service in a thread pool
+from fastapi.concurrency import run_in_threadpool + async def upload_dataset_endpoint( ... ) -> APIResponse[DatasetUploadResponse]: """Upload an evaluation dataset.""" # Validate and read CSV file csv_content = await validate_csv_file(file) # Upload dataset using service - dataset = upload_dataset( + dataset = await run_in_threadpool( + upload_dataset, session=_session, csv_content=csv_content, dataset_name=dataset_name, description=description, duplication_factor=duplication_factor, organization_id=auth_context.organization.id, project_id=auth_context.project.id, ) return APIResponse.success_response(data=_dataset_to_response(dataset))Option 2: Make the service async (requires refactoring service layer)
This would require making
upload_datasetand its dependencies async, which is a larger refactor but provides better async integration.Note: The other endpoints (
evaluate,get_evaluation_run_status) are correctly defined as sync (def), so FastAPI automatically runs them in a thread pool.
🧹 Nitpick comments (5)
backend/app/services/evaluation/dataset.py (1)
131-138: Consider sanitizing exception details in client-facing error message.Exposing raw exception messages (
{e}) could leak internal implementation details (stack traces, connection strings, etc.) to API clients.🔎 Apply this diff to provide a generic error message:
except Exception as e: logger.error( f"[upload_dataset] Failed to upload dataset to Langfuse | {e}", exc_info=True, ) raise HTTPException( - status_code=500, detail=f"Failed to upload dataset to Langfuse: {e}" + status_code=500, detail="Failed to upload dataset to Langfuse. Please check your Langfuse credentials and try again." )backend/app/services/evaluation/evaluation.py (3)
23-28: Consider more specific type hints forconfigparameter.Using
dictwithout type parameters reduces type safety. As per coding guidelines requiring type hints, consider usingdict[str, Any]for clarity.🔎 Apply this diff:
+from typing import Any + def build_evaluation_config( session: Session, - config: dict, + config: dict[str, Any], assistant_id: str | None, project_id: int, -) -> dict: +) -> dict[str, Any]:
101-109: Consider more specific type hints forconfigparameter here as well.Same suggestion as
build_evaluation_configfor consistency.
313-319: Consider sanitizing exception details in error message.Similar to the dataset service, exposing raw exception messages could leak internal details.
🔎 Apply this diff:
except Exception as e: logger.error( f"[get_evaluation_with_scores] Failed to fetch trace info | " f"evaluation_id={evaluation_id} | error={e}", exc_info=True, ) - return eval_run, f"Failed to fetch trace info from Langfuse: {str(e)}" + return eval_run, "Failed to fetch trace info from Langfuse. Please try again later."backend/app/api/routes/evaluation.py (1)
67-67: Consider enriching docstrings with parameter and behavior details.The added docstrings are present but minimal, mostly restating the function names. For route handlers that delegate to services, consider documenting:
- Key parameter constraints or validation rules
- Important response scenarios (e.g., 404 vs 422)
- Side effects or async behavior notes
Example for
upload_dataset_endpoint:""" Upload an evaluation dataset from a CSV file. Validates CSV format and content, uploads to Langfuse and optional object store, and persists metadata. Runs synchronously in a thread pool to avoid blocking. """This is optional since the Swagger descriptions are loaded from external markdown files.

56-64: LGTM! Mock paths correctly updated to reflect service layer refactoring.The patch targets are properly updated from
app.api.routes.evaluation.*toapp.services.evaluation.dataset.*, aligning with the new service-oriented architecture.
142-150: Mock paths consistently updated for empty rows test.
188-196: Mock paths consistently updated for default duplication test.
229-237: Mock paths consistently updated for custom duplication test.
270-278: Mock paths consistently updated for description test.
362-370: Mock paths consistently updated for boundary minimum test.
407-410: Mock paths consistently updated for Langfuse configuration failure test.backend/app/crud/evaluations/__init__.py (3)
4-9: LGTM! Properly exportssave_scorefrom core module.The new export aligns with the service layer's need to persist evaluation scores.
26-31: LGTM! Properly exportsfetch_trace_scores_from_langfusefrom langfuse module.This enables the evaluation service to retrieve trace scores via the CRUD layer's public API.
39-70: LGTM!__all__correctly updated with new exports.Both
save_scoreandfetch_trace_scores_from_langfuseare properly listed in the appropriate sections.backend/app/services/evaluation/validators.py (4)
13-20: LGTM! Well-defined security constants.Clear file upload limits with appropriate MIME type allowances including
text/plainfor compatibility.
23-68: LGTM! Well-documented sanitization with comprehensive rules.The function handles edge cases properly, includes clear examples in the docstring, and follows coding guidelines with type hints.
100-115: LGTM! Thorough file size validation.Properly seeks to end for size check and resets position before reading.
118-174: LGTM! Robust CSV parsing with case-insensitive headers.Good approach to normalize headers while preserving original column names for row access. Properly filters empty rows and re-raises
HTTPExceptionwithout wrapping.backend/app/services/evaluation/dataset.py (4)
24-32: LGTM! Well-typed function signature.All parameters have proper type hints including the union type for optional
description. As per coding guidelines, type hints are correctly applied.
58-74: LGTM! Proper sanitization with informative logging.Logging follows the
[function_name]prefix convention as per coding guidelines.
86-108: LGTM! Graceful degradation for object store failures.Non-fatal handling allows the workflow to continue when object storage is unavailable, which is appropriate for optional storage backends.
140-163: LGTM! Clean metadata construction and database persistence.The metadata structure is well-organized and the final logging confirms successful creation.
backend/app/services/evaluation/__init__.py (1)
1-32: LGTM! Clean public API surface definition.Well-organized exports with clear categorization. The
__all__list provides a clear contract for the evaluation services package.backend/app/services/evaluation/evaluation.py (8)
47-86: LGTM! Robust assistant config merging logic.Properly handles the merge precedence where provided config values override assistant values, and conditionally adds tools when vector stores are available.
88-98: LGTM! Proper validation for direct config usage.Clear error message when model is missing and no assistant_id is provided.
142-170: LGTM! Thorough dataset validation with clear error messages.Properly validates both dataset existence and Langfuse ID presence before proceeding.
179-200: LGTM! Clean client initialization and evaluation run creation.Follows the documented workflow steps clearly.
229-236: LGTM! Well-typed return signature.The
tuple[EvaluationRun | None, str | None]return type clearly communicates the possible outcomes.
276-286: LGTM! Proper caching logic for trace scores.Correctly checks both completion status and existing cached scores before fetching from Langfuse.
321-329: LGTM! Clean score persistence flow.Uses the separate-session
save_scorefunction correctly to persist scores after the primary fetch operation.
219-226: The error handling behavior is correct and intentional.start_evaluation_batchproperly setsstatus = "failed"with anerror_messagebefore re-raising the exception. The exception is then caught instart_evaluation, andsession.refresh(eval_run)retrieves the updated failure state from the database. The approach is sound—error details are persisted before exception propagation, ensuring the evaluation run maintains failure context when returned to the caller.backend/app/api/routes/evaluation.py (2)
1-23: LGTM: Clean service-oriented refactoring.The refactoring to delegate business logic to service modules improves separation of concerns and maintainability. The route handlers are now thin wrappers focused on HTTP concerns.
294-295: Graceful degradation pattern is intentional and well-designed.Lines 294-295 correctly use
APIResponse.failure_response(), which is explicitly designed to support returning data alongside errors. Thefailure_response()method signature includes an optionaldata: Optional[T] = Noneparameter, and the response is constructed with bothsuccess=False,error=error_message, anddata=data. This pattern is appropriate for cases where the evaluation run exists but additional enrichment (like trace info) fails, allowing clients to receive partial data along with error context.

Handle potential None filename.
file.filename can be None for certain upload scenarios. Path(None) will raise TypeError.
🔎 Apply this diff to handle None filename:
# Security validation: Check file extension

+ detail="File must have a filename",
+ )
file_ext = Path(file.filename).suffix.lower()🤖 Prompt for AI Agents
In backend/app/services/evaluation/validators.py around lines 84 to 90,
file.filename can be None which makes Path(file.filename) raise TypeError; guard
against a missing filename first and return the same 422 HTTPException with a
clear message if it's None (e.g., "Missing filename or invalid upload"),
otherwise safely compute the suffix (lowercased) from the filename and continue
the existing allowed-extension check and error path.

51-81: Add logging to endpoint and address blocking I/O pattern.Two issues found:
Missing logging: This endpoint lacks logging despite other endpoints in the file logging operations with
[function_name]prefix. Per coding guidelines, add a log statement prefixed with[upload_dataset_endpoint].Blocking I/O in async context:
upload_datasetis a synchronous function that performs blocking I/O operations (database writes, object store uploads, Langfuse API calls). Calling it directly in an async endpoint blocks the event loop. Consider wrapping it withasyncio.to_thread()or refactoring the service function to be async.Suggested fix for logging:
async def upload_dataset_endpoint( ... ) -> APIResponse[DatasetUploadResponse]: """Upload an evaluation dataset.""" + logger.info( + f"[upload_dataset_endpoint] Uploading dataset | " + f"name={dataset_name} | org_id={auth_context.organization.id} | " + f"project_id={auth_context.project.id}" + ) # Validate and read CSV file csv_content = await validate_csv_file(file) # Upload dataset using service dataset = upload_dataset(

1-37: Add an explicit__all__list to declare the public API.Per PEP 8, modules should explicitly declare the names in their public API using the
__all__attribute. This module currently imports 21+ functions from six submodules without defining__all__, which means all imported names become part of the public API by default. Using__all__allows you to explicitly specify the public interface of your packages and modules and prevents accidental usage of objects that shouldn't be used from outside the module. Define an__all__list after the module docstring containing the functions intended as part of the public API.

201-225: LGTM: Simplified evaluation orchestration.The endpoint correctly delegates evaluation orchestration to
start_evaluation, simplifying the route handler and moving business logic to the service layer as intended by this refactor.
264-312: LGTM: Proper error handling for evaluation scores.The endpoint correctly handles the tuple return from
get_evaluation_with_scoresand appropriately usesfailure_responsewhen an error is present. This maintains a consistent API response structure while delegating the complex Langfuse interaction to the service layer.
