⚡ Recommended focus areas for review Null Safety The CreateDevToolsDomain method can return null but is used without null check in line 128. While the code will likely work due to the logic flow, explicit null checking would improve robustness. private static DevToolsDomains? CreateDevToolsDomain(int protocolVersion, DevToolsSession session) => protocolVersion switch { 130 => new V130.V130Domains(session), 132 => new V132.V132Domains(session), 131 => new V131.V131Domains(session), 85 => new V85.V85Domains(session), _ => null }; Version Ordering The SupportedProtocolVersions array defines versions in a seemingly random order (130,132,131,85). Consider ordering them consistently to improve maintainability. private static int[] SupportedProtocolVersions => [ 130, 132, 131, 85 ];

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add parameter validation Add null check for the 'session' parameter in InitializeDomains methods to prevent potential NullReferenceException when creating domain instances. dotnet/src/webdriver/DevTools/DevToolsDomains.cs [89-92] public static DevToolsDomains InitializeDomains(int protocolVersion, DevToolsSession session) { + ArgumentNullException.ThrowIfNull(session); return InitializeDomains(protocolVersion, session, DefaultVersionRange); } Apply this suggestion Suggestion importance[1-10]: 8 Why: Adding null validation for the session parameter is crucial for preventing NullReferenceException and providing clear error messages. This is particularly important as the session parameter is used throughout the domain initialization process.	8
	Validate protocol version parameter Add validation for negative protocol version to prevent potential issues with version matching logic. dotnet/src/webdriver/DevTools/DevToolsDomains.cs [103-108] public static DevToolsDomains InitializeDomains(int protocolVersion, DevToolsSession session, int versionRange) { + if (protocolVersion < 0) + { + throw new ArgumentOutOfRangeException(nameof(protocolVersion), "Protocol version must not be negative"); + } if (versionRange < 0) { throw new ArgumentOutOfRangeException(nameof(versionRange), "Version range must not be negative"); } Apply this suggestion Suggestion importance[1-10]: 7 Why: Adding validation for negative protocol versions is important for preventing invalid inputs early, especially since the version matching logic assumes positive version numbers. This complements the existing versionRange validation.	7
