Hey @Karanjot786 - I've reviewed your changes - here's some feedback:

Overall Comments:

Consider using datetime.datetime objects instead of strings for start_time and end_time in the WESLog model to improve type safety.
The truncate_system_logs validator in WESLog could be simplified using value[:MAX_SYSTEM_LOGS] without the conditional.

Here's what I looked at during the review

🟢 General issues: all looks good
🟢 Security: all looks good
🟡 Testing: 2 issues found
🟢 Complexity: all looks good
🟢 Documentation: all looks good

+        assert wes_data.run_log == run_log
+        assert wes_data.task_logs_url.startswith("https://")
+        assert wes_data.task_logs == [task_log]
+        assert all(url.startswith("https://") for url in wes_data.outputs.values())


suggestion (testing): Consider testing different URL schemes in outputs

The current test assumes all URLs in outputs start with "https://". It would be more robust to test with different URL schemes (e.g., "s3://", "file://") or even relative paths to ensure the model handles them correctly. This would improve test coverage for different storage scenarios.

Thanks a lot @Karanjot786 - please address the Sourcery AI comments, they are all reasonable, then ask me and @SalihuDickson for a re-review 🙏

Thanks @Karanjot786. Looks okay to me - but I would prefer for @SalihuDickson to have a look as well first, before merging.

Thanks @Karanjot786. Looks okay to me - but I would prefer for @SalihuDickson to have a look as well first, before merging.

Sure, @uniqueg. Sorry for the delayed response. I've been extremely busy, but I'll take a look at it in the next day or two.

+MAX_SYSTEM_LOGS = 2
+
+
+class WESState(str, Enum):


for the class names i think its best to just use the exact names listed in the WES docs. This would ensure that the references match exactly and make all this much simpler to read.

I’ll update the class names so they exactly match the names used in the official WES documentation. This change will improve readability and ensure consistency with the reference.

SalihuDickson · 2025-03-26T10:43:27Z

crategen/models/wes_models.py

+
+    - **UNKNOWN**: The state of the workflow is unknown.
+    - **QUEUED**: The workflow is queued.
+    - **INITIALIZING**: The workflow is initializing.


The comment I made on the class names applies here as well. In the instances where a short and clear description has already been made available in the docs, there is really no need to write something different, you should just copy the first line or first sentence, like you did with the UNKNOWN and QUEUED attributes above

I’ll modify the descriptions for the enum values to use the first sentence from the docs directly. This way, the descriptions for states like UNKNOWN, QUEUED, and INITIALIZING will be consistent with the official definitions.

crategen/models/wes_models.py

+    PREEMPTED = "PREEMPTED"
+
+
+class WESOutputs(BaseModel):


Please adjust the class name here as well, to match with the one listed in the reference docs.

Where did you get the attributes for the output? The reference you cited seems to be made up. And the output specification does not match what is in the docs.

I understand that the reference for outputs seems off. I will review the official WES docs and adjust the class name and its attributes accordingly. The updated model will correctly reflect the output specifications as per the reference.

SalihuDickson · 2025-03-26T10:49:16Z

crategen/models/wes_models.py

+
+    - **name** (`Optional[str]`): The task or workflow name.
+    - **cmd** (`Optional[list[str]]`): The command line that was executed.
+    - **start_time** (`Optional[str]`): When the command started executing, in RFC 3339 format.


Please use the description in the docs, we don't want conflicting descriptions. Do the same for all the descriptions for the attributes here that don't match.

But please note, you don't need to copy the entire description, just the first sentence should be okay. Unless the first sentence is not descriptive enough.

For all models (e.g., WESLog, WESTaskLog, etc.), I’ll replace my current descriptions with the first sentence from the official documentation. This ensures no conflicts arise between our descriptions and the official docs.

Please adjust the class name to match the reference in the docs

I will update the WESTaskLog class name to match exactly what is specified in the WES reference documentation.

crategen/models/wes_models.py

+    name: str = Field(...)
+

The class should match the name in the listed reference

I’ll verify name is required and that other fields conform exactly to the WES specification.

crategen/models/wes_models.py

+
+    **Attributes:**
+
+    - **workflow_params** (`Optional[dict[str, str]]`): The workflow run parameterizations (JSON encoded),


why does the description say optional when it is required?

I’ll correct the docstring for workflow_params to reflect that it’s a required field.

+        return values
+

adjust the class name to match the name of the model as listed in the reference.

I’ll ensure the root validators properly return values and follow best practices.

+      This attribute is deprecated.
+    - **outputs** (`dict[str, str]`): The outputs of the WES run.
+
+    **Reference:** https://ga4gh.github.io/workflow-execution-service-schemas/docs/#tag/run_model


this reference seems to be made up

I’ll rename WESData to match the docs and revise the outputs description if necessary.

SalihuDickson · 2025-03-26T14:01:37Z

crategen/models/wes_models.py

+
+    **Attributes:**
+
+    - **run_id** (`str`): The unique identifier for the WES run.


The issue with the descriptions applies here as well. Check the descriptions for all the other attributes as well.

I’ll confirm that run_id aligns with the official specs and update if needed.

SalihuDickson

Great work so far @Karanjot786, please take a look at these changes and resubmit for review.

Do not forget to ask for clarification if there is something you don't understand or that you are not sure of. Making changes you're unsure of will only create more work for reviewers.

SalihuDickson · 2025-03-26T14:17:41Z

tests/unit/test_wes_models.py

you should only be testing the validation functions. Most of these tests are testing pydantic itself, you don't want to be testing external packages, such tests are completely unnecessary and considered bad practice.

Please rewrite this module and submit for another review.

Karanjot786 · 2025-03-26T17:04:29Z

Hi @SalihuDickson and @uniqueg,

I've rewritten the module based on your feedback.

Update WES Models to Conform to GA4GH Spec

Renamed classes to match official documentation:
- WESState → State
- WESLog → Log
- WESTaskLog → TaskLog
- WESRunRequest → RunRequest
- Added new Run model to represent a workflow run.
Updated docstrings to use concise, one-sentence descriptions directly from the GA4GH WES documentation.
Removed truncation logic for system_logs since the spec does not impose any limits.
Ensured RFC 3339 datetime validation is correctly implemented in Log.
Added a root validator in RunRequest to enforce that workflow_engine is provided when workflow_engine_version is set.
Updated tests in test_wes_models.py to focus on our custom validation and model behavior.
