PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Return merged node result In the MergeNode method, return the newNode variable, which holds the result of the _membase.MergeNodeAsync call, instead of the original node parameter. src/Plugins/BotSharp.Plugin.Membase/Services/MembaseService.cs [43] -return node; +return newNode; [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 8 __ Why: This suggestion correctly identifies a critical bug where the method returns its input argument instead of the result of the database operation, effectively discarding the update.	Medium
Learned best practice	Guard against null collections Guard against node.Labels being null (e.g., when deserialized or externally constructed) before using the spread operator. src/Plugins/BotSharp.Plugin.Membase/Services/MembaseService.cs [38] -Labels = [.. node.Labels], +Labels = node.Labels is { Count: > 0 } ? [.. node.Labels] : [], [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 5 __ Why: Relevant best practice - Add explicit null/empty guards before enumerating or spreading collections to prevent null dereferences.	Low
