    PR Review

    โฑ๏ธ Estimated effort to review [1-5] 2, because the changes are localized to a specific functionality (Bluetooth radio detection) and the logic is straightforward. The PR modifies the initialization logic to iterate through all radios instead of directly retrieving the Bluetooth adapter, and adds a console output if no Bluetooth radio is available. The changes are not extensive but require a good understanding of the async programming model and Bluetooth API.
    ๐Ÿงช Relevant tests No
    ๐Ÿ” Possible issues Possible Bug: The loop breaks as soon as a Bluetooth radio is found and assigns it to `bluetoothRadio`. If there are multiple Bluetooth radios available, this logic will only consider the first one found. This might not be an issue depending on the application's requirements, but it's worth noting if handling multiple Bluetooth radios is a desired feature.
    Debugging Information: Adding a console output when Bluetooth is not available is helpful for debugging, but consider if this is the best approach for all use cases. In some scenarios, logging to a file or using another logging mechanism might be more appropriate, especially for release builds or applications with a GUI.
    ๐Ÿ”’ Security concerns No

    โœจ 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://pr-agent-docs.codium.ai/usage-guide/automations_and_usage/#github-app-automatic-tools-when-a-new-pr-is-opened) 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://pr-agent-docs.codium.ai/usage-guide/configuration_options/), 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://pr-agent-docs.codium.ai/usage-guide/automations_and_usage/#github-app-automatic-tools-when-a-new-pr-is-opened) 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://pr-agent-docs.codium.ai/tools/review/#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 ```

    Best practice
    Use a consistent logging mechanism instead of std::cout. ___ **Instead of using std::cout for logging that Bluetooth is not available, consider using a
    logging framework or mechanism that is consistent with the rest of your application. This
    approach allows for better control over logging levels and destinations (e.g., file,
    console, network) and can help with debugging and monitoring the application in production
    environments.** [windows/src/universal_ble_plugin.cpp [515]](https://github.com/Navideck/universal_ble/pull/20/files#diff-c744a38517e9dcb9177126ffd1392b9decc2b53e55772d4270f4387a4f4c9357R515-R515) ```diff -std::cout << "Bluetooth is not available" << std::endl; +LogError("Bluetooth is not available"); ```
    Maintainability
    Abstract Bluetooth radio availability check into a separate method. ___ **To improve code readability and maintainability, consider abstracting the logic for
    checking the availability of the Bluetooth radio into a separate method. This approach
    makes the InitializeAsync method cleaner and emphasizes the high-level logic without the
    clutter of implementation details.** [windows/src/universal_ble_plugin.cpp [503-516]](https://github.com/Navideck/universal_ble/pull/20/files#diff-c744a38517e9dcb9177126ffd1392b9decc2b53e55772d4270f4387a4f4c9357R503-R516) ```diff -auto radios = co_await Radio::GetRadiosAsync(); -for (auto &&radio : radios) -{ - if (radio.Kind() == RadioKind::Bluetooth) - { - bluetoothRadio = radio; - radioStateChangedRevoker = bluetoothRadio.StateChanged(winrt::auto_revoke, {this, &UniversalBlePlugin::Radio_StateChanged}); - break; - } -} +bluetoothRadio = await FindBluetoothRadioAsync(); if (!bluetoothRadio) { - std::cout << "Bluetooth is not available" << std::endl; + LogError("Bluetooth is not available"); } ```
    Enhancement
    Handle the absence of Bluetooth radio more gracefully. ___ **Ensure that the application gracefully handles the scenario where no Bluetooth radio is
    available. Instead of just logging the issue, consider providing a fallback mechanism or
    notifying the user/application through a callback or an event. This proactive handling can
    improve the user experience and application robustness.** [windows/src/universal_ble_plugin.cpp [513-516]](https://github.com/Navideck/universal_ble/pull/20/files#diff-c744a38517e9dcb9177126ffd1392b9decc2b53e55772d4270f4387a4f4c9357R513-R516) ```diff if (!bluetoothRadio) { - std::cout << "Bluetooth is not available" << std::endl; + LogError("Bluetooth is not available"); + NotifyRadioUnavailable(); } ```
    Possible issue
    Check the result of GetRadiosAsync for null or failure before use. ___ **Consider checking the result of Radio::GetRadiosAsync() for null or failure before
    iterating over the radios. This additional check can prevent potential runtime errors if
    the GetRadiosAsync call fails or returns null, ensuring the application's stability.** [windows/src/universal_ble_plugin.cpp [503-504]](https://github.com/Navideck/universal_ble/pull/20/files#diff-c744a38517e9dcb9177126ffd1392b9decc2b53e55772d4270f4387a4f4c9357R503-R504) ```diff auto radios = co_await Radio::GetRadiosAsync(); +if (radios == nullptr) return; for (auto &&radio : radios) ```
    Performance
    Use an efficient logging level for indicating unavailable Bluetooth. ___ **For better performance and resource management, consider using a more efficient logging
    level or mechanism when indicating that Bluetooth is not available. For instance, logging
    this as an error or warning (depending on the application's context) might be more
    appropriate than a standard output, which could be overlooked.** [windows/src/universal_ble_plugin.cpp [515]](https://github.com/Navideck/universal_ble/pull/20/files#diff-c744a38517e9dcb9177126ffd1392b9decc2b53e55772d4270f4387a4f4c9357R515-R515) ```diff -std::cout << "Bluetooth is not available" << std::endl; +LogWarning("Bluetooth is not available"); ```

    โœจ 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://pr-agent-docs.codium.ai/usage-guide/automations_and_usage/#github-app-automatic-tools-when-a-new-pr-is-opened) 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://pr-agent-docs.codium.ai/usage-guide/configuration_options/), use the following template: ``` [pr_code_suggestions] some_config1=... some_config2=... ```
    Enabling\disabling automation
    When you first install the app, the [default mode](https://pr-agent-docs.codium.ai/usage-guide/automations_and_usage/#github-app-automatic-tools-when-a-new-pr-is-opened) 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://pr-agent-docs.codium.ai/tools/custom_suggestions/) tool - With large PRs, best quality will be obtained by using 'improve --extended' mode.
