    PR Review

    ⏱️ Estimated effort to review [1-5] 2, because the changes are focused on a single test file with a clear purpose: enhancing test coverage for scan timeout scenarios. The modifications are straightforward and well-defined, making the review process less time-consuming.
    🧪 Relevant tests Yes
    🔍 Possible issues Test Coverage for Edge Cases: While the added test case for scan timeout is valuable, ensure that edge cases around the exact timeout boundary are also considered. For instance, what happens if the scan completes exactly at the timeout threshold?
    Time Precision: The use of `1 * time.Millisecond` as a timeout in tests might lead to flakiness in environments with variable execution speeds. Consider if a slightly longer timeout could still effectively test the functionality without risking flaky tests.
    🔒 Security concerns No
    ✨ Review tool usage guide:
    **Overview:** The `review` tool scans the PR code changes, and generates a PR review. The tool can be triggered [automatically](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) every time a new PR is opened, or can be invoked manually by commenting on any PR. When commenting, to edit [configurations](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L19) 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](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-app), 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](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) 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](https://github.com/Codium-ai/pr-agent/blob/tr/user_description/pr_agent/settings/pr_reviewer_prompts.toml#L136) (`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](https://github.com/Codium-ai/pr-agent/blob/main/docs/REVIEW.md#enabledisable-features), 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 ```

    Enhancement
    Use a more realistic timeout value in the test case for better real-world scenario simulation. ___ **Consider using a more realistic timeout value for the scanTimeout in the test case "big
    image produces incomplete SBOM because of scanTimeout". A value of 1 * time.Millisecond is
    extremely short and might not be practical for real-world scenarios. Using a more
    realistic timeout value can help ensure that the test case better reflects actual usage
    conditions.** [adapters/v1/syft_test.go [76]](https://github.com/kubescape/kubevuln/pull/215/files#diff-58134a5183879fd2da27ae7458a485bf76579b87e7269f07d7f440086178b470R76-R76) ```diff -scanTimeout: 1 * time.Millisecond, +scanTimeout: 10 * time.Second, ```
    Maintainability
    Extract timeout and size setting logic into a separate function for better readability. ___ **To improve code readability and maintainability, consider extracting the logic for setting
    scanTimeout and maxImageSize into a separate function. This will make the test setup more
    concise and easier to understand, especially as more parameters may be added in the
    future.** [adapters/v1/syft_test.go [110-112]](https://github.com/kubescape/kubevuln/pull/215/files#diff-58134a5183879fd2da27ae7458a485bf76579b87e7269f07d7f440086178b470R110-R112) ```diff -scanTimeout := 5 * time.Minute -if tt.scanTimeout > 0 { - scanTimeout = tt.scanTimeout -} +scanTimeout := determineScanTimeout(tt.scanTimeout) ```
    Best practice
    Use context.WithTimeout for managing operation timeouts more effectively. ___ **It's recommended to use context.WithTimeout instead of manually setting timeouts on
    operations. This approach provides a more standardized way of handling timeouts in Go,
    making the code more idiomatic and easier to manage, especially for operations that might
    hang or need cancellation support.** [adapters/v1/syft_test.go [110-112]](https://github.com/kubescape/kubevuln/pull/215/files#diff-58134a5183879fd2da27ae7458a485bf76579b87e7269f07d7f440086178b470R110-R112) ```diff -scanTimeout := 5 * time.Minute -if tt.scanTimeout > 0 { - scanTimeout = tt.scanTimeout -} +ctx, cancel := context.WithTimeout(context.Background(), scanTimeout) +defer cancel() ```
    ✨ Improve tool 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](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) every time a new PR is opened, or can be invoked manually by commenting on a PR. When commenting, to edit [configurations](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L69) 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](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-app), use the following template: ``` [pr_code_suggestions] some_config1=... some_config2=... ```
    Enabling\disabling automation
    When you first install the app, the [default mode](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) for the improve tool is: ``` pr_commands = ["/improve --pr_code_suggestions.summarize=true", ...] ``` 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, or use the [custom suggestions :gem:](https://github.com/Codium-ai/pr-agent/blob/main/docs/CUSTOM_SUGGESTIONS.md) tool - With large PRs, best quality will be obtained by using 'improve --extended' mode.
