PR Feedback

💡 General suggestions: The PR is well-structured and the changes are logically grouped. The use of Poetry as a dependency manager is a good choice as it simplifies dependency management. However, it would be beneficial to add a brief explanation in the PR description about why Poetry was chosen over other options. This would provide more context to reviewers and future contributors.

🤖 Code feedback:

---

relevant file	docker/Dockerfile
suggestion	Consider using multi-stage builds to reduce the final image size. This can be done by installing the dependencies in a builder image, and then copying them over to a slimmer production image. [important]
relevant line	FROM python:$PYTHON_VERSION as builder

---

relevant file	docker/Dockerfile
suggestion	It's a good practice to pin the versions of the base images to ensure the Docker builds are repeatable. [medium]

Hi @lukefx we didn't forget about it, it will take a bit longer as we need to carefully test several configuration and Dockerfiles, but all of your changes make sense and we'll merge them (ETA: 1 month).

PR Review

⏱️ Estimated effort to review [1-5]	3, because the PR involves significant changes in dependency management and Docker configurations, which requires a thorough review of configurations and understanding of the Poetry tool. The changes also span across multiple files and include updates to documentation, which adds to the complexity.
🧪 Relevant tests	No
🔍 Possible issues	Possible Bug: The Dockerfile for AWS Lambda uses poetry install without specifying --without dev or --no-dev, potentially including development dependencies in the production build.
	Performance Concern: In docker/Dockerfile, exporting requirements to requirements-dev.txt using poetry export inside the builder stage and then installing these dev dependencies in the test stage might lead to unnecessary duplication and increase build time.
🔒 Security concerns	No
🔀 Multiple PR themes	Sub-PR theme: Update Docker Configurations for Poetry Relevant files: docker/Dockerfile docker/Dockerfile.lambda
	Sub PR theme: Introduce Poetry for Dependency Management Relevant files: pyproject.toml requirements-dev.txt requirements.txt

Code feedback:

---

relevant file	docker/Dockerfile.lambda
suggestion	Consider using poetry install --no-dev to ensure that development dependencies are not included in the AWS Lambda deployment package. This can help reduce the size of the deployment package and potentially improve cold start times for the Lambda function. [important]
relevant line	RUN poetry install && rm pyproject.toml

---

relevant file	docker/Dockerfile
suggestion	Instead of exporting dev dependencies to requirements-dev.txt and installing them in the test stage, consider installing dev dependencies directly using poetry install in the test stage. This can simplify the Dockerfile and potentially reduce build times by avoiding unnecessary steps. [medium]
relevant line	RUN poetry export -f requirements.txt -o requirements-dev.txt --only=dev

---

relevant file	docker/Dockerfile
suggestion	To enhance security, consider explicitly setting a non-root user in the builder stage as well. While the final stages use a non-root user, doing so in the builder stage can help mitigate risks during the build process. [medium]
relevant line	FROM python:$PYTHON_VERSION as builder

---

relevant file	docker/Dockerfile.lambda
suggestion	After running yum update -y, it's a good practice to remove cache and temporary files created during the update to reduce the Docker image size. Consider adding && yum clean all after the yum update -y command. [medium]
relevant line	RUN yum update -y && \

✨ Review tool usage guide:

---

Overview:
The review tool scans the PR code changes, and generates a PR review. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on any PR.
When commenting, to edit configurations related to the review tool (pr_reviewer section), use the following template:

/review --pr_reviewer.some_config1=... --pr_reviewer.some_config2=...

With a configuration file, use the following template:

[pr_reviewer]
some_config1=...
some_config2=...

Utilizing extra instructions The review tool can be configured with extra instructions, which can be used 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. Specify the relevant sub-tool, and the relevant aspects of the PR that you want to emphasize. Examples for extra instructions: [pr_reviewer] # /review # extra_instructions=""" In the 'possible issues' section, emphasize the following: - 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.

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

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_ticket, require_can_be_split_review, and more.

Auto-approve PRs By invoking: /review auto_approve The tool will automatically approve the PR, and add a comment with the approval. To ensure safety, the auto-approval feature is disabled by default. To enable auto-approval, you need to actively set in a pre-defined configuration file the following: [pr_reviewer] enable_auto_approval = true (this specific flag cannot be set with a command line argument, only in the configuration file, committed to the repository) You can also enable auto-approval only if the PR meets certain requirements, such as that the estimated_review_effort is equal or below a certain threshold, by adjusting the flag: [pr_reviewer] maximal_review_effort = 5

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 [--extended]: Suggest code improvements. Extended mode provides a higher quality feedback. /ask <QUESTION>: Ask a question about the PR. /update_changelog: Update the changelog based on the PR's contents. /add_docs 💎: Generate docstring for new components introduced in the PR. /generate_labels 💎: Generate labels for the PR based on the PR's contents. /analyze 💎: Automatically analyzes the PR, and presents changes walkthrough for each component. See the tools guide for more details. To list the possible configuration parameters, add a /config comment.
