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.

PR Code Suggestions

	Suggestions
enhancement	Improve error handling strategy for better resilience and debugging.          Consider using a more specific error handling strategy instead of returning immediately when encountering an error. This could involve logging the error, retrying the operation, or implementing a fallback mechanism, depending on the criticality of the operation and its potential impact on application functionality. pkg/applicationprofilemanager/v1/applicationprofile_manager.go [72-77] if err != nil { + // Log the error + logger.L().Error("Encountered an error", helpers.Error(err)) + // Consider retrying the operation or implementing a fallback mechanism return } Add more context to log messages for improved debugging and reliability.      To ensure the accuracy and reliability of logging, consider adding more context to the log messages throughout the application. This could involve including additional details such as the specific operation being performed, the values of key variables, and the state of the application at the time of logging. pkg/applicationprofilemanager/v1/applicationprofile_manager.go [73-76] -logger.L().Ctx(ctx).Error("ApplicationProfileManager - failed to get workload", helpers.Error(err), +// Example of adding more context to the log message +logger.L().Ctx(ctx).Error("ApplicationProfileManager - failed to get workload for container", + helpers.Error(err), helpers.Int("container index", watchedContainer.ContainerIndex), helpers.String("container ID", watchedContainer.ContainerID), - helpers.String("k8s workload", watchedContainer.K8sContainerID)) + helpers.String("k8s workload", watchedContainer.K8sContainerID), + helpers.String("operation", "GetWorkload"), + helpers.String("namespace", container.K8s.Namespace), + helpers.String("pod name", container.K8s.PodName)) Replace time.Sleep with a more precise wait mechanism in tests.  Consider using a more precise wait mechanism instead of time.Sleep for synchronization in tests to reduce the overall test execution time and improve test reliability. You can use channels or wait groups to synchronize goroutines or consider using a mocking framework to control the timing more precisely. pkg/applicationprofilemanager/v1/applicationprofile_manager_test.go [61] -time.Sleep(15 * time.Second) // need to sleep longer because of AddRandomDuration in startApplicationProfiling +// Example using a wait group +var wg sync.WaitGroup +wg.Add(1) +go func() { + defer wg.Done() + // Your asynchronous operation here +}() +wg.Wait() // This will block until the operation completes Use descriptive assertions for complex structure comparisons in tests.        To enhance test reliability and readability, consider using a more descriptive assertion framework or helper functions for comparing complex structures like ApplicationProfile. <br> This <br> can <br> provide <br> clearer <br> error <br> messages <br> on <br> test <br> failure <br> and <br> reduce <br> boilerplate <br> comparison <br> code. pkg/storage/v1/storage_test.go [343] -assert.Equal(t, tt.want, got) +assertApplicationProfileEquals(t, tt.want, got) // This is a custom function that needs to be implemented
possible issue	Ensure thread safety when modifying shared data structures.                   To avoid potential race conditions and ensure thread safety, consider using concurrent data structures or synchronization mechanisms (like mutexes) when accessing and modifying shared data structures such as trackedContainers, savedCapabilities, savedExecs, <br> ``savedOpens, <br> and <br> ``savedSyscalls. pkg/applicationprofilemanager/v1/applicationprofile_manager.go [137-144] +// Example using mutex for thread-safe operation +am.mutex.Lock() +defer am.mutex.Unlock() am.trackedContainers.Remove(watchedContainer.K8sContainerID) am.savedCapabilities.Delete(watchedContainer.K8sContainerID) am.savedExecs.Delete(watchedContainer.K8sContainerID) am.savedOpens.Delete(watchedContainer.K8sContainerID) am.savedSyscalls.Delete(watchedContainer.K8sContainerID)
maintainability	Refactor large function into smaller, focused functions for better maintainability. To improve code maintainability and readability, consider refactoring the large saveProfile function by breaking it down into smaller, more focused functions. This could involve separating the logic for handling syscalls, capabilities, execs, and opens into distinct functions. pkg/applicationprofilemanager/v1/applicationprofile_manager.go [170-464] +// Refactored version with smaller functions func (am *ApplicationProfileManager) saveProfile(ctx context.Context, watchedContainer *utils.WatchedContainerData, namespace string) { - ... + am.handleSyscalls(ctx, watchedContainer, namespace) + am.handleCapabilities(ctx, watchedContainer, namespace) + am.handleExecs(ctx, watchedContainer, namespace) + am.handleOpens(ctx, watchedContainer, namespace) } Refactor conditional logic for clarity in GetApplicationProfile. To improve the readability and maintainability of the GetApplicationProfile method, consider refactoring the conditional logic to return early if sc.ApplicationProfiles is not empty. This reduces the nesting level and makes the code easier to follow. pkg/storage/storage_mock.go [44-54] -if len(sc.ApplicationProfiles) == 0 { - return &spdxv1beta1.ApplicationProfile{ - Spec: spdxv1beta1.ApplicationProfileSpec{ - Containers: []spdxv1beta1.ApplicationProfileContainer{ - {Capabilities: []string{"SYS_ADMIN"}}, - {Capabilities: []string{"NET_BROADCAST"}}, - }, +if len(sc.ApplicationProfiles) > 0 { + return sc.ApplicationProfiles[len(sc.ApplicationProfiles)-1], nil +} +return &spdxv1beta1.ApplicationProfile{ + Spec: spdxv1beta1.ApplicationProfileSpec{ + Containers: []spdxv1beta1.ApplicationProfileContainer{ + {Capabilities: []string{"SYS_ADMIN"}}, + {Capabilities: []string{"NET_BROADCAST"}}, }, - }, nil -} -return sc.ApplicationProfiles[len(sc.ApplicationProfiles)-1], nil + }, +}, nil
performance	Optimize data processing and storage operations in saveProfile for better performance. To enhance the performance and efficiency of the saveProfile function, consider optimizing the data processing and storage operations. This could involve batching database writes, caching frequently accessed data, and minimizing the use of blocking operations. pkg/applicationprofilemanager/v1/applicationprofile_manager.go [170-464] -func (am *ApplicationProfileManager) saveProfile(ctx context.Context, watchedContainer *utils.WatchedContainerData, namespace string) { +// Example of optimizing data processing and storage operations +func (am *ApplicationProfileManager) saveProfileOptimized(ctx context.Context, watchedContainer *utils.WatchedContainerData, namespace string) { + // Implement batching for database writes + // Cache frequently accessed data + // Minimize blocking operations ... } Review efficiency of sorting slices converted from sets.                      When using sort.Strings on slices that are converted from a set, ensure that the conversion process does not introduce any unexpected behavior or performance issues, especially with large sets. Consider if maintaining order during insertion or using a different data structure might be more efficient for your use case. pkg/utils/utils.go [227-228] -args := exec.ToSlice() -sort.Strings(args) +// If order is important and the set is large, consider alternatives to sorting after conversion.
best practice	Ensure ResourceVersion is only unset when necessary.             Ensure that the ResourceVersion field is only unset when necessary. Unsetting this field indiscriminately can lead to unintended consequences, such as bypassing optimistic concurrency control. Consider adding a check to determine if unsetting this field is necessary based on the operation being performed or the state of the ApplicationProfile. pkg/storage/v1/storage_nocache.go [107] -profile.ResourceVersion = "" +if needToResetResourceVersion(profile) { + profile.ResourceVersion = "" +}

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.
