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:

/describe --pr_description.some_config1=... --pr_description.some_config2=...

With a configuration file, use the following template:

[pr_description]
some_config1=...
some_config2=...

Enabling\disabling automation When you first install the app, the default mode for the describe tool is: pr_commands = ["/describe --pr_description.add_original_user_description=true" "--pr_description.keep_original_user_title=true", ...] 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: pr_commands = ["/describe --pr_description.use_description_markers=true", ...] 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.

Inline File Walkthrough 💎 For enhanced user experience, the describe tool can add file summaries directly to the "Files changed" tab in the PR page. This will enable you to quickly understand the changes in each file, while reviewing the code changes (diffs). To enable inline file summary, set pr_description.inline_file_summary in the configuration file, possible values are: 'table': File changes walkthrough table will be displayed on the top of the "Files changed" tab, in addition to the "Conversation" tab. true: A collapsable file comment with changes title and a changes summary for each file in the PR. false (default): File changes walkthrough will be added only to the "Conversation" tab.

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. /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.

PR Code Suggestions

	Suggestions
enhancement	Wrap errors with additional context before logging or sending them.           Consider wrapping the error with additional context before logging it or sending it back. This can help in understanding the error better during debugging and provides more detailed logs. mainhandler/handlerequests.go [203] -logger.L().Ctx(ctx).Error("failed to complete action", helpers.String("command", string(sessionObj.Command.CommandName)), helpers.String("wlid", sessionObj.Command.GetID()), helpers.Error(err)) +wrappedErr := fmt.Errorf("handling single request for command %s with wlid %s: %w", sessionObj.Command.CommandName, sessionObj.Command.GetID(), err) +logger.L().Ctx(ctx).Error("failed to complete action", helpers.String("command", string(sessionObj.Command.CommandName)), helpers.String("wlid", sessionObj.Command.GetID()), helpers.Error(wrappedErr))
performance	Check if debug logging is enabled before constructing log messages.           It's a good practice to check if the logger is enabled for the specific log level before constructing log messages, especially debug logs that might not always be enabled. This can improve performance by avoiding unnecessary string operations. mainhandler/handlerequests.go [464] -logger.L().Debug("scan request", helpers.String("url", scanUrl.String()), helpers.String("wlid", command.GetWlid()), helpers.String("instanceID", instanceID), helpers.String("imageTag", command.GetImageTag()), helpers.String("imageHash", command.GetImageHash()), helpers.Interface("credentials", hasCreds)) +if logger.L().IsDebugEnabled() { + logger.L().Debug("scan request", helpers.String("url", scanUrl.String()), helpers.String("wlid", command.GetWlid()), helpers.String("instanceID", instanceID), helpers.String("imageTag", command.GetImageTag()), helpers.String("imageHash", command.GetImageHash()), helpers.Interface("credentials", hasCreds)) +}
best practice	Pass dependencies as interfaces to improve testability.                       To ensure that the HandleSingleRequest method can be easily tested, consider passing dependencies such as NewActionHandler as interfaces to the method or struct. This allows for better unit testing by enabling mocking of these dependencies. mainhandler/handlerequests.go [217] -actionHandler := NewActionHandler(mainHandler.config, mainHandler.k8sAPI, sessionObj, mainHandler.commandResponseChannel) +// Assume ActionHandlerInterface is an interface that NewActionHandler implements. +func (mainHandler *MainHandler) HandleSingleRequest(ctx context.Context, sessionObj *utils.SessionObj, actionHandler ActionHandlerInterface) error {
maintainability	Use constants for API version and kind to improve maintainability.            Instead of hardcoding the API version and kind in the HandleImageScanningScopedRequest method, consider using constants or retrieving these values from a configuration. This makes the code more maintainable and flexible to changes. mainhandler/handlerequests.go [394-395] -pod.APIVersion = "v1" -pod.Kind = "Pod" +pod.APIVersion = DefaultAPIVersion // Assume DefaultAPIVersion is a constant defined elsewhere. +pod.Kind = DefaultPodKind // Assume DefaultPodKind is a constant defined elsewhere. Create a helper function for generating expected commands in tests.           To avoid duplication and improve maintainability, consider creating a helper function for generating expected commands in tests. This function can take parameters for the varying parts of the command and return a constructed command object. watcher/podwatcher_test.go [327-341] expectedCommands: []apis.Command{ - { - CommandName: apis.TypeScanImages, - Wlid: "wlid://...", - Args: map[string]interface{}{ - ... - }, - }, + generateExpectedCommand(apis.TypeScanImages, "wlid://...", /* other varying parameters */), } +// generateExpectedCommand would be a helper function defined elsewhere in the test file.

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:

[pr_code_suggestions]
some_config1=...
some_config2=...

Enabling\disabling automation When you first install the app, the default mode 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 💎 tool With large PRs, best quality will be obtained by using 'improve --extended' mode.
