Overview:
The describe tool scans the PR code changes, and generates a description for the PR - title, type, summary, walkthrough and labels. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on a PR.
When commenting, to edit configurations related to the describe tool (pr_description section), use the following template:
meaning the describe tool will run automatically on every PR, will keep the original title, and will add the original user description above the generated description.
Markers are an alternative way to control the generated description, to give maximal control to the user. If you set:
the tool will replace every marker of the form pr_agent:marker_name in the PR description with the relevant content, where marker_name is one of the following:
type: the PR type.
summary: the PR summary.
walkthrough: the PR walkthrough.
Note that when markers are enabled, if the original PR description does not contain any markers, the tool will not alter the description at all.
Custom labels
The default labels of the describe tool are quite generic: [Bug fix, Tests, Enhancement, Documentation, Other].
If you specify custom labels in the repo's labels page or via configuration file, you can get tailored labels for your use cases.
Examples for custom labels:
Main topic:performance - pr_agent:The main topic of this PR is performance
New endpoint - pr_agent:A new endpoint was added in this PR
SQL query - pr_agent:A new SQL query was added in this PR
Dockerfile changes - pr_agent:The PR contains changes in the Dockerfile
...
The list above is eclectic, and aims to give an idea of different possibilities. Define custom labels that are relevant for your repo and use cases.
Note that Labels are not mutually exclusive, so you can add multiple label categories.
Make sure to provide proper title, and a detailed and well-phrased description for each label, so the tool will know when to suggest it.
Utilizing extra instructions
The describe tool can be configured with extra instructions, to guide the model to a feedback tailored to the needs of your project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Notice that the general structure of the description is fixed, and cannot be changed. Extra instructions can change the content or style of each sub-section of the PR description.
Examples for extra instructions:
[pr_description]
extra_instructions="""
- The PR title should be in the format: '<PR type>: <title>'
- The title should be short and concise (up to 10 words)
- ...
"""
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
More PR-Agent commands
To invoke the PR-Agent, add a comment using one of the following commands:
/review: Request a review of your Pull Request.
/describe: Update the PR title and description based on the contents of the PR.

PR Feedback
💡 General suggestions: The PR is well-structured and focuses on enhancing the test coverage for network policies. The addition of more detailed logging and refactoring of validation methods is a good improvement. However, it would be beneficial to add more comments in the code to explain the logic, especially for complex test scenarios.
🤖 Code feedback:

How to enable\disable automation
When you first install PR-Agent app, the default mode for the review tool is:
pr_commands = ["/review", ...]
meaning the review tool will run automatically on every PR, with the default configuration.
Edit this field to enable/disable the tool, or to change the used configurations
About the 'Code feedback' section
The review tool provides several type of feedbacks, one of them is code suggestions.
If you are interested only in the code suggestions, it is recommended to use the improve feature instead, since it dedicated only to code suggestions, and usually gives better results.
Use the review tool if you want to get a more comprehensive feedback, which includes code suggestions as well.
Auto-labels
The review tool can auto-generate two specific types of labels for a PR:
a possible security issue label, that detects possible security issues (enable_review_labels_security flag)
a Review effort [1-5]: x label, where x is the estimated effort to review the PR (enable_review_labels_effort flag)
Extra sub-tools
The review tool provides a collection of possible feedbacks about a PR.
It is recommended to review the possible options, and choose the ones relevant for your use case.
Some of the feature that are disabled by default are quite useful, and should be considered for enabling. For example: require_score_review, require_soc2_review, enable_review_labels_effort, and more.
More PR-Agent commands
To invoke the PR-Agent, add a comment using one of the following commands:
/review: Request a review of your Pull Request.
/describe: Update the PR title and description based on the contents of the PR.
Improve readability of error messages by reducing the amount of data printed.
In the method validate_expected_backend_workloads_list, there is a potential issue with <br> the <br> ``assert statement. If the lengths of workloads_list and expected_workloads_list are not equal, the error message will print the entire lists. If these lists are large, this could lead to a very long and hard-to-read error message. Consider printing only the lengths of the lists, or a subset of the lists, in the error message.
-assert len(workloads_list) == len(expected_workloads_list), f"workloads_list length is not equal to expected_workloads_list length, actual: len:{len(workloads_list)}, expected: len:{len(expected_workloads_list)}; actual results: {workloads_list}, expected results: {expected_workloads_list}"+assert len(workloads_list) == len(expected_workloads_list), f"workloads_list length is not equal to expected_workloads_list length, actual: len:{len(workloads_list)}, expected: len:{len(expected_workloads_list)}"
best practice
Improve error handling by failing fast when an exception occurs.
In the method validate_expected_backend_generated_network_policy_list, the errors list is used to collect exceptions and then checked at the end of the method. However, the method continues to execute even after an exception is caught. Consider failing fast and raising an exception immediately when an error occurs, instead of collecting errors and checking at the end. This can make debugging easier and prevent unnecessary code execution.
-errors = []
for i in range(0, len(expected_network_policy_list)):
...
except Exception as e:
- errors.append(e)- continue-...-assert len(errors) == 0, f"Errors in validate_expected_backend_generated_network_policy_list: {errors}"+ raise Exception(f"Error in validate_expected_backend_generated_network_policy_list: {e}")
Replace assert statements with exceptions for error checking in production code.
In the method get_network_policies_generate, the assert statements are used to check the response from the API call. However, using assert statements for error checking in production code is not recommended because they can be globally disabled with the -O and -OO command line switches. Consider raising exceptions instead.
Add checks to ensure function parameters are not None and contain the required keys before using them.
In the method validate_network_policy_spec, the expected_network_policy_spec and actual_network_policy_spec parameters are used directly without checking if they are None or if they have the required keys. This could lead to a KeyError or TypeError if the parameters are not as expected. Consider adding checks to ensure the parameters are not None and contain the required keys before using them.

✨ Usage guide:
Overview:
The improve tool scans the PR code changes, and automatically generates suggestions for improving the PR code. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on a PR.
When commenting, to edit configurations related to the improve tool (pr_code_suggestions section), use the following template:
meaning the improve tool will run automatically on every PR, with summarization enabled. Delete this line to disable the tool from running automatically.
Utilizing extra instructions
Extra instructions are very important for the improve tool, since they enable to guide the model to suggestions that are more relevant to the specific needs of the project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify relevant aspects that you want the model to focus on.
Examples for extra instructions:
[pr_code_suggestions] # /improve #
extra_instructions="""
Emphasize the following aspects:
- Does the code logic cover relevant edge cases?
- Is the code logic clear and easy to understand?
- Is the code logic efficient?
...
"""
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
A note on code suggestions quality
While the current AI for code is getting better and better (GPT-4), it's not flawless. Not all the suggestions will be perfect, and a user should not accept all of them automatically.
Suggestions are not meant to be simplistic. Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base.
Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project.
Best quality will be obtained by using 'improve --extended' mode.
