✨ 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, 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.

Add guidance on setting allowPrivilegeEscalation to false in the remediation section. Clarify the remediation section to include guidance on setting allowPrivilegeEscalation to false, as it is another important security practice to prevent privilege escalation. controls/C-0013-nonrootcontainers.json [10] -"remediation": "If your application does not need root privileges, make sure to define runAsNonRoot as true or explicitly set the runAsUser using ID 1000 or higher under the PodSecurityContext or container securityContext. In addition, set an explicit value for runAsGroup using ID 1000 or higher." +"remediation": "If your application does not need root privileges, make sure to define runAsNonRoot as true or explicitly set the runAsUser using ID 1000 or higher under the PodSecurityContext or container securityContext. In addition, set an explicit value for runAsGroup using ID 1000 or higher. Also, ensure `allowPrivilegeEscalation` is set to false to prevent any privilege escalation." Add a verification step for allowPrivilegeEscalation in the test section. In the test section, suggest adding a verification step for allowPrivilegeEscalation to ensure it is explicitly set to false, complementing the security measures outlined. controls/C-0013-nonrootcontainers.json [15] -"test": "Verify that runAsUser is set to a user id greater than 0 or that runAsNonRoot is set to true, and that runAsGroup is set to an id greater than 0.

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:

/improve --pr_code_suggestions.some_config1=... --pr_code_suggestions.some_config2=...

With a configuration file, use the following template:

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, or use the custom suggestions 💎 tool With large PRs, best quality will be obtained by using 'improve --extended' mode.

enhancement	Enhance the clarity and rationale in the remediation guidance.                To enhance clarity and precision, consider rephrasing the remediation guidance to explicitly mention the avoidance of using root privileges unless necessary, and to provide a brief rationale for using IDs 1000 or higher. This can help users understand not just the 'how' but also the 'why' behind the instructions. controls/C-0013-nonrootcontainers.json [10] -"remediation": "If your application does not need root privileges, make sure to define runAsNonRoot as true or explicitly set the runAsUser using ID 1000 or higher under the PodSecurityContext or container securityContext. In addition, set an explicit value for runAsGroup using ID 1000 or higher." +"remediation": "Avoid using root privileges unless absolutely necessary. When root privileges are not required, set `runAsNonRoot` to true or explicitly define `runAsUser` and `runAsGroup` with IDs 1000 or higher under the PodSecurityContext or container securityContext. Using IDs 1000 or higher helps in minimizing the risk of unauthorized system access."
clarity	Specify exact locations for compliance checks in the test description.        To improve the test description's clarity and actionability, consider specifying the exact locations where runAsUser, runAsNonRoot, and runAsGroup should be checked within the Kubernetes resource definitions. This can help users more effectively verify compliance with the control. controls/C-0013-nonrootcontainers.json [15] -"test": "Verify that runAsUser is set to a user id greater than 0 or that runAsNonRoot is set to true, and that runAsGroup is set to an id greater than 0. Check all the combinations with PodSecurityContext and SecurityContext (for containers)." +"test": "Ensure `runAsUser` is set to a user ID greater than 0, `runAsNonRoot` is true, and `runAsGroup` is set to an ID greater than 0 within both PodSecurityContext and container-level SecurityContext. Verify these settings in Deployment, StatefulSet, and DaemonSet resource definitions to ensure compliance."
