PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Sensitive data logging Description: The handler reads and logs the full raw HTTP response body (`rawResponse`) in `#if DEBUG`, which may expose sensitive data (e.g., user/graph content or secrets returned by the API) into application logs if debug builds are deployed or logs are collected in shared environments. MembaseAuthHandler.cs [20-28] Referred Code protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage requestMessage, CancellationToken cancellationToken) { requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); var response = await base.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false); #if DEBUG var rawResponse = await response.Content.ReadAsStringAsync(); _logger.LogDebug(rawResponse); #endif
Ticket Compliance
⚪	🎫 No ticket provided Create ticket/issue
Codebase Duplication Compliance
⚪	Codebase context is not defined Follow the guide to enable codebase context checks.
Custom Compliance
🟢	Generic: Secure Error Handling Objective: To prevent the leakage of sensitive system information through error messages while providing sufficient detail for internal debugging. Status: Passed Learn more about managing compliance generic rules or creating your own custom rules
🔴	Generic: Meaningful Naming and Self-Documenting Code Objective: Ensure all identifiers clearly express their purpose and intent, making code self-documenting Status: Ambiguous tuple return: `GetCodeExecutionConfig` returns an unnamed `(bool, bool, int)` tuple which is not self-documenting and can easily lead to misuse at call sites. Referred Code public static (bool, bool, int) GetCodeExecutionConfig(CodingSettings settings, int defaultTimeoutSeconds = 3) { var codeExecution = settings.CodeExecution; var useLock = codeExecution?.UseLock ?? false; var useProcess = codeExecution?.UseProcess ?? false; var timeoutSeconds = codeExecution?.TimeoutSeconds > 0 ? codeExecution.TimeoutSeconds : defaultTimeoutSeconds; return (useLock, useProcess, timeoutSeconds); Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Secure Logging Practices Objective: To ensure logs are useful for debugging and auditing without exposing sensitive information like PII, PHI, or cardholder data. Status: Logs raw HTTP body: The handler logs `rawResponse` directly (`_logger.LogDebug(rawResponse)`), which is unstructured and may expose sensitive data returned by the Membase API. Referred Code var rawResponse = await response.Content.ReadAsStringAsync(); _logger.LogDebug(rawResponse); #endif Learn more about managing compliance generic rules or creating your own custom rules
⚪	Generic: Comprehensive Audit Trails Objective: To create a detailed and reliable record of critical system actions for security analysis and compliance. Status: Missing audit logging: New Membase graph capabilities (node/edge CRUD and graph info retrieval) are introduced without any visible audit logging that records actor/context/outcome for these critical actions. Referred Code [Get("/graph/{graphId}")] Task<GraphInfo> GetGraphInfoAsync(string graphId); [Post("/cypher/execute")] Task<CypherQueryResponse> CypherQueryAsync([Query] string graphId, CypherQueryRequest request); #region Node [Get("/graph/{graphId}/node/{nodeId}")] Task<Node> GetNodeAsync(string graphId, string nodeId); [Post("/graph/{graphId}/node")] Task<Node> CreateNodeAsync(string graphId, [Body] NodeCreationModel node); [Put("/graph/{graphId}/node/{nodeId}")] Task<Node> UpdateNodeAsync(string graphId, string nodeId, [Body] NodeUpdateModel node); [Put("/graph/{graphId}/node/{nodeId}/merge")] Task<Node> MergeNodeAsync(string graphId, string nodeId, [Body] NodeUpdateModel node); [Delete("/graph/{graphId}/node/{nodeId}")] Task<NodeDeleteResponse?> DeleteNodeAsync(string graphId, string nodeId); ... (clipped 15 lines) Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Robust Error Handling and Edge Case Management Objective: Ensure comprehensive error handling that provides meaningful context and graceful degradation Status: No non-success handling: The new HTTP auth handler forwards responses without checking or enriching handling for non-success HTTP statuses, so failures may propagate without actionable context unless handled elsewhere. Referred Code protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage requestMessage, CancellationToken cancellationToken) { requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); var response = await base.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false); #if DEBUG var rawResponse = await response.Content.ReadAsStringAsync(); _logger.LogDebug(rawResponse); #endif return response; } Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Security-First Input Validation and Data Handling Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent vulnerabilities Status: No request validation: New request DTOs (e.g., `EdgeCreationModel`, `NodeCreationModel` with `EmbeddingInfo`) introduce externally supplied fields without any visible validation/sanitization constraints, so correctness and security depend on validation elsewhere. Referred Code public class EdgeCreationModel { public string? Id { get; set; } public string SourceNodeId { get; set; } = null!; public string TargetNodeId { get; set; } = null!; public string Type { get; set; } = null!; public bool Directed { get; set; } = true; public float?

PR Code Suggestions ✨

Latest suggestions up to dfdec70

Category	Suggestion	Impact
Incremental ^[*]	Return proper not-found response Modify the `GetConversation` method to return an `ActionResult` instead of `ConversationViewModel?`. When a conversation is not found, return an HTTP 404 `NotFound()` result instead of an empty object to provide clearer API responses. src/Infrastructure/BotSharp.OpenAPI/Controllers/Conversation/ConversationController.cs [145-188] -public async Task<ConversationViewModel?> GetConversation([FromRoute] string conversationId, [FromQuery] bool isLoadStates = false) +public async Task<ActionResult<ConversationViewModel>> GetConversation([FromRoute] string conversationId, [FromQuery] bool isLoadStates = false) { var convService = _services.GetRequiredService<IConversationService>(); var userService = _services.GetRequiredService<IUserService>(); var settings = _services.GetRequiredService<PluginSettings>(); var (isAdmin, user) = await userService.IsAdminUser(_user.Id); var filter = new ConversationFilter { Id = conversationId, UserId = !isAdmin ? user?.Id : null, IsLoadLatestStates = isLoadStates }; var conversations = await convService.GetConversations(filter); var conversation = conversations.Items?.FirstOrDefault(); if (conversation == null) { - return new(); + return NotFound(); } user = !string.IsNullOrEmpty(conversation.UserId) ? await userService.GetUser(conversation.UserId) : null; if (user == null) { user = new User { Id = _user.Id, UserName = _user.UserName, FirstName = _user.FirstName, LastName = _user.LastName, Email = _user.Email, Source = "Unknown" }; } var conversationView = ConversationViewModel.FromSession(conversation); conversationView.User = UserViewModel.FromUser(user); conversationView.IsRealtimeEnabled = settings?.Assemblies?.Contains("BotSharp.Core.Realtime") ?? false; return conversationView; } Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly points out that returning an empty object on failure is poor API design. Returning a proper HTTP status code like 404 is a significant improvement for client-side error handling and API semantics, and also has security benefits.	Medium
	Avoid logging raw file data In the `ToString()` method, instead of returning a substring of `FileData`, return a summary string like `""`. This prevents accidentally logging potentially large or sensitive file content. src/Infrastructure/BotSharp.Abstraction/Files/Models/InstructFileModel.cs [32-35] else if (!string.IsNullOrEmpty(FileData)) { - return FileData.SubstringMax(50); + return $"<inline-file-data len={FileData.Length}>"; } Apply / Chat Suggestion importance[1-10]: 7 __ Why: This suggestion correctly identifies a potential security and logging issue where raw file data could be leaked into logs via `ToString()`. Replacing the raw data with a summary is a good practice for security and log management, especially since the PR increased the amount of data being exposed.	Medium
	Prevent null list crashes Revert the `Files` property from a nullable list back to a non-nullable list initialized as empty. This change prevents potential `NullReferenceException` and adheres to best practices for handling collections. src/Infrastructure/BotSharp.OpenAPI/ViewModels/Instructs/Request/InstructMessageModel.cs [13] -public List<InstructFileModel>? Files { get; set; } +public List<InstructFileModel> Files { get; set; } = []; Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies that changing the `Files` property to be nullable is a regression in code quality, as it can lead to `NullReferenceException`. Reverting to a non-nullable, initialized list is a standard best practice that improves robustness.	Low
Possible issue	Make deletes resilient to empty bodies Wrap the return types of `DeleteNodeAsync` and `DeleteEdgeAsync` with `ApiResponse` to prevent potential Refit deserialization failures when the API returns an empty response body (e.g., with a `204 No Content` status). src/Plugins/BotSharp.Plugin.Membase/Services/IMembaseApi.cs [30-45] [Delete("/graph/{graphId}/node/{nodeId}")] -Task<NodeDeleteResponse?> DeleteNodeAsync(string graphId, string nodeId); +Task<ApiResponse<NodeDeleteResponse>> DeleteNodeAsync(string graphId, string nodeId); ... [Delete("/graph/{graphId}/edge/{edgeId}")] -Task<EdgeDeleteResponse> DeleteEdgeAsync(string graphId, string edgeId); +Task<ApiResponse<EdgeDeleteResponse>> DeleteEdgeAsync(string graphId, string edgeId); `[To ensure code accuracy, apply this suggestion manually]` Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a potential runtime deserialization error if the `DELETE` endpoints return a `204 No Content` status, which is a common REST practice. Using `ApiResponse<T>` makes the client more robust by allowing it to handle non-success status codes and empty response bodies gracefully.	Medium
Possible issue	Validate configuration before creating URI Add validation to ensure `settings.Host` is a valid absolute URI before configuring the `HttpClient`'s `BaseAddress`. This prevents application startup crashes from invalid configuration and provides a clear error message. src/Plugins/BotSharp.Plugin.Membase/MembasePlugin.cs [18-24] services.AddTransient<MembaseAuthHandler>(); services.AddRefitClient<IMembaseApi>(new RefitSettings { CollectionFormat = CollectionFormat.Multi }) .AddHttpMessageHandler<MembaseAuthHandler>() - .ConfigureHttpClient(c => c.BaseAddress = new Uri(settings.Host)); + .ConfigureHttpClient(c => + { + if (string.IsNullOrWhiteSpace(settings.Host) \|\| + !Uri.TryCreate(settings.Host, UriKind.Absolute, out var baseUri)) + { + throw new InvalidOperationException("Membase Host must be a valid absolute URI."); + } + c.BaseAddress = baseUri; + }); + Apply / Chat Suggestion importance[1-10]: 7 __ Why: The suggestion correctly points out that an invalid `settings.Host` value can cause the application to crash on startup. Adding validation for the URI makes the application more robust and provides clearer error messages for misconfigurations, improving diagnosability.	Medium

✅ Suggestions up to commit 6bf71f2

Category	Suggestion	Impact
Possible issue	✅ ~~Annotate request body parameter~~ Suggestion Impact: The CypherQueryAsync method signature was updated to annotate the request parameter with [Body], ensuring it is serialized into the POST request body. code diff: [Post("/cypher/execute")] - Task<CypherQueryResponse> CypherQueryAsync([Query] string graphId, CypherQueryRequest request); + Task<CypherQueryResponse> CypherQueryAsync([Query] string graphId, [Body] CypherQueryRequest request); Add the `[Body]` attribute to the `request` parameter in the `CypherQueryAsync` method to ensure it's sent in the HTTP request body. src/Plugins/BotSharp.Plugin.Membase/Services/IMembaseApi.cs [15] -Task<CypherQueryResponse> CypherQueryAsync([Query] string graphId, CypherQueryRequest request); +Task<CypherQueryResponse> CypherQueryAsync([Query] string graphId, [Body] CypherQueryRequest request); `[Suggestion processed]` Suggestion importance[1-10]: 9 __ Why: The suggestion correctly points out the missing `[Body]` attribute, which is critical for the `POST` request to function correctly by sending the request object in the body.	High
	Avoid consuming the response stream Avoid consuming the response stream when logging. After reading the response content for logging, replace it with a new `StringContent` so it can be read again by the caller. src/Plugins/BotSharp.Plugin.Membase/Services/MembaseAuthHandler.cs [20-31] protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage requestMessage, CancellationToken cancellationToken) { requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); var response = await base.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false); #if DEBUG - var rawResponse = await response.Content.ReadAsStringAsync(); - _logger.LogDebug(rawResponse); + if (response.Content != null) + { + var rawResponse = await response.Content.ReadAsStringAsync(cancellationToken); + _logger.LogDebug(rawResponse); + + // Re-wrap the content to make it readable again by the caller. + response.Content = new StringContent(rawResponse, System.Text.Encoding.UTF8, response.Content.Headers.ContentType?.MediaType ?? "application/json"); + } #endif return response; } Suggestion importance[1-10]: 8 __ Why: This suggestion correctly identifies a critical bug where logging the response body consumes the content stream, which would cause deserialization to fail for the actual caller.	Medium
	Ensure handler uses updated settings To ensure `MembaseAuthHandler` uses the latest settings if they become reloadable, register it using a factory in `AddHttpMessageHandler` to resolve it per request. src/Plugins/BotSharp.Plugin.Membase/MembasePlugin.cs [18-24] +services.AddTransient<MembaseAuthHandler>(); +services.AddRefitClient<IMembaseApi>(new RefitSettings + { + CollectionFormat = CollectionFormat.Multi + }) + .AddHttpMessageHandler<MembaseAuthHandler>() + .ConfigureHttpClient(c => c.BaseAddress = new Uri(settings.Host)); - Suggestion importance[1-10]: 5 __ Why: The suggestion correctly identifies a potential DI lifecycle issue with `DelegatingHandler`, but the problem it describes (stale settings) won't occur with the current singleton registration of `MembaseSettings`.	Low
General	Initialize embedding properties Initialize the `Model` and `Vector` properties in the `EmbeddingInfo` class to default values to prevent potential null reference issues. src/Plugins/BotSharp.Plugin.Membase/Models/Requests/NodeCreationModel.cs [24-28] public class EmbeddingInfo { - public string Model { get; set; } - public float[] Vector { get; set; } + public string Model { get; set; } = string.Empty; + public float[] Vector { get; set; } = Array.Empty<float>(); } Suggestion importance[1-10]: 6 __ Why: The suggestion improves robustness by initializing properties to non-null defaults, preventing potential `NullReferenceException` issues during object creation or deserialization.	Low
General	Name tuple return elements Improve readability by naming the return tuple elements in the `GetCodeExecutionConfig` method signature (e.g., `(bool useLock, bool useProcess,` `int timeoutSeconds)`). src/Infrastructure/BotSharp.Abstraction/Coding/Utils/CodingUtil.cs [11] -public static (bool, bool, int) GetCodeExecutionConfig(CodingSettings settings, int defaultTimeoutSeconds = 3) +public static (bool useLock, bool useProcess, int timeoutSeconds) GetCodeExecutionConfig(CodingSettings settings, int defaultTimeoutSeconds = 3) Suggestion importance[1-10]: 4 __ Why: This is a good suggestion for improving code readability and maintainability by naming the elements of the returned tuple, making the method's signature more self-documenting.	Low
Learned best practice	Validate auth header and cancellation Validate the API key before adding the Authorization header and pass the provided cancellation token when reading the response content. src/Plugins/BotSharp.Plugin.Membase/Services/MembaseAuthHandler.cs [20-31] protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage requestMessage, CancellationToken cancellationToken) { - requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); + if (!string.IsNullOrWhiteSpace(_settings.ApiKey)) + { + requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); + } + var response = await base.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false); #if DEBUG - var rawResponse = await response.Content.ReadAsStringAsync(); + var rawResponse = await response.Content.ReadAsStringAsync(cancellationToken); _logger.LogDebug(rawResponse); #endif return response; } Suggestion importance[1-10]: 5 __ Why: Relevant best practice - Improve defensive coding with precise null and state checks to prevent incorrect behavior.

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Sensitive data exposure Description: The new SSE endpoint serializes and streams the full `InstructResult` including `result.States` (populated from externally supplied `input.` and `input.Files`) which can unintentionally expose sensitive data (e.g., file content snippets or secrets placed into states) to the client and any intermediaries that can observe the response.

Explore these optional code suggestions:

Category	Suggestion	Impact
High-level	Re-evaluate the Server-Sent Events implementation The SSE endpoint should be refactored to stream partial results as they are generated, rather than computing the entire response and sending it as a single event. This requires modifying the underlying service to support streaming. Examples: src/Infrastructure/BotSharp.OpenAPI/Controllers/Instruct/InstructModeController.cs [50-72] public async Task InstructCompletionSse([FromRoute] string agentId, [FromBody] InstructMessageModel input) { var state = _services.GetRequiredService<IConversationStateService>(); SetStates(state, input); Response.StatusCode = 200; Response.Headers.Append(Microsoft.Net.Http.Headers.HeaderNames.ContentType, "text/event-stream"); Response.Headers.Append(Microsoft.Net.Http.Headers.HeaderNames.CacheControl, "no-cache"); Response.Headers.Append(Microsoft.Net.Http.Headers.HeaderNames.Connection, "keep-alive"); ... (clipped 13 lines) Solution Walkthrough: Before: public async Task InstructCompletionSse(...) { // ... set up response headers for SSE // Await the full result from the service var result = await instructor.Execute(...); // Send the complete result as a single SSE event await OnChunkReceived(Response, result); } private async Task OnChunkReceived(HttpResponse response, InstructResult result) { var json = JsonSerializer.Serialize(result, ...); var buffer = Encoding.UTF8.GetBytes($"data:{json}\n\n"); await response.Body.WriteAsync(buffer); await response.Body.FlushAsync(); } After: public async Task InstructCompletionSse(...) { // ... set up response headers for SSE // The service now returns a stream of partial results // (e.g., using IAsyncEnumerable or a callback) await foreach (var partialResult in instructor.ExecuteStream(...)) { // Send each partial result as a separate SSE event await SendSseChunk(Response, partialResult); } } private async Task SendSseChunk(HttpResponse response, PartialResult partialResult) { var json = JsonSerializer.Serialize(partialResult, ...); var buffer = Encoding.UTF8.GetBytes($"data:{json}\n\n"); await response.Body.WriteAsync(buffer); await response.Body.FlushAsync(); } Suggestion importance[1-10]: 9 __ Why: The suggestion correctly identifies a fundamental design flaw in the new SSE endpoint, where the entire result is computed before being sent as a single event, defeating the purpose of streaming.	High
Possible issue	Prevent null in embedding info Initialize the `Model` and `Vector` properties in the `EmbeddingInfo` class to non-null default values to avoid potential null reference errors. src/Plugins/BotSharp.Plugin.Membase/Models/Requests/NodeCreationModel.cs [24-28] public class EmbeddingInfo { - public string Model { get; set; } - public float[] Vector { get; set; } + public string Model { get; set; } = string.Empty; + public float[] Vector { get; set; } = Array.Empty<float>(); } Apply / Chat Suggestion importance[1-10]: 6 __ Why: Initializing properties to non-null default values is a good practice that prevents potential `NullReferenceException`s and makes the class more robust.

Learned best practice	Add null-safe state setting Guard against `input`/`input.States` being null (and optionally null keys) before iterating to avoid `NullReferenceException` when clients omit fields. src/Infrastructure/BotSharp.OpenAPI/Controllers/Instruct/InstructModeController.cs [148-163] private void SetStates(IConversationStateService state, InstructMessageModel input) { - input.States.ForEach(x => state.SetState(x.Key, x.Value, activeRounds: x.ActiveRounds, source: StateSource.External)); + if (input?.States != null) + { + foreach (var x in input.States.Where(s => !string.IsNullOrWhiteSpace(s.Key))) + { + state.SetState(x.Key, x.Value, activeRounds: x.ActiveRounds, source: StateSource.External); + } + } - state.SetState("provider", input.Provider, source: StateSource.External) - .SetState("model", input.Model, source: StateSource.External) - .SetState("model_id", input.ModelId, source: StateSource.External) - .SetState("instruction", input.Instruction, source: StateSource.External) - .SetState("input_text", input.Text, source: StateSource.External) - .SetState("template_name", input.Template, source: StateSource.External) - .SetState("channel", input.Channel, source: StateSource.External) - .SetState("code_options", input.CodeOptions, source: StateSource.External) - .SetState("file_options", input.FileOptions, source: StateSource.External) - .SetState("file_count", input.Files?.Count, source: StateSource.External) - .SetState("file_urls", input.Files?.Select(p => p.ToString()), source: StateSource.External); + state.SetState("provider", input?.Provider, source: StateSource.External) + .SetState("model", input?.Model, source: StateSource.External) + .SetState("model_id", input?.ModelId, source: StateSource.External) + .SetState("instruction", input?.Instruction, source: StateSource.External) + .SetState("input_text", input?.Text, source: StateSource.External) + .SetState("template_name", input?.Template, source: StateSource.External) + .SetState("channel", input?.Channel, source: StateSource.External) + .SetState("code_options", input?.CodeOptions, source: StateSource.External) + .SetState("file_options", input?.FileOptions, source: StateSource.External) + .SetState("file_count", input?.Files?.Count, source: StateSource.External) + .SetState("file_urls", input?.Files?.Select(p => p.ToString()), source: StateSource.External); } Apply / Chat Suggestion importance[1-10]: 6 __ Why: Relevant best practice - Add defensive null checks for request collections/properties before iterating or dereferencing to prevent runtime exceptions.	Low
Learned best practice	Don’t consume response content Buffer the content before reading/logging (or skip body logging) so you don’t consume the response stream and break Refit’s deserialization. src/Plugins/BotSharp.Plugin.Membase/Services/MembaseAuthHandler.cs [20-31] protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage requestMessage, CancellationToken cancellationToken) { requestMessage.Headers.TryAddWithoutValidation("Authorization", $"Bearer {_settings.ApiKey}"); var response = await base.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false); #if DEBUG - var rawResponse = await response.Content.ReadAsStringAsync(); - _logger.LogDebug(rawResponse); + if (response.Content != null) + { + await response.Content.LoadIntoBufferAsync(cancellationToken).ConfigureAwait(false); + var rawResponse = await response.Content.ReadAsStringAsync(cancellationToken).ConfigureAwait(false); + _logger.LogDebug(rawResponse); + } #endif return response; } Apply / Chat Suggestion importance[1-10]: 5 __ Why: Relevant best practice - Avoid consuming response streams in handlers; preserve error/details without breaking downstream processing.	Low
General	Fix method name typo Fix the typo in the method name from `GetConversationStateSearhKeys` to `GetConversationStateSearchKeys` and update all its usages. src/Infrastructure/BotSharp.Abstraction/Conversations/IConversationService.cs [64] -Task<List<string>> GetConversationStateSearhKeys(ConversationStateKeysFilter filter); +Task<List<string>> GetConversationStateSearchKeys(ConversationStateKeysFilter filter); `[To ensure code accuracy, apply this suggestion manually]` Suggestion importance[1-10]: 5 __ Why: The suggestion correctly identifies a typo in a method name. Fixing it improves code clarity and maintainability, and the suggestion also correctly notes that all references must be updated.	Low
General	Name tuple return values Add names to the tuple elements in the return type of `GetCodeExecutionConfig` to improve readability. src/Infrastructure/BotSharp.Abstraction/Coding/Utils/CodingUtil.cs [11-20] -public static (bool, bool, int) GetCodeExecutionConfig(CodingSettings settings, int defaultTimeoutSeconds = 3) +public static (bool useLock, bool useProcess, int timeoutSeconds) GetCodeExecutionConfig(CodingSettings settings, int defaultTimeoutSeconds = 3) { var codeExecution = settings.CodeExecution; var useLock = codeExecution?.UseLock ?? false; var useProcess = codeExecution?.UseProcess ?? false; var timeoutSeconds = codeExecution?.TimeoutSeconds > 0 ? codeExecution.TimeoutSeconds : defaultTimeoutSeconds; return (useLock, useProcess, timeoutSeconds); } Apply / Chat Suggestion importance[1-10]: 4 __ Why: The suggestion correctly points out that naming tuple return values improves code readability and maintainability for consumers of the method.
