125-125: Consider explicit type declaration for better readability.While using
auto constis valid here, an explicitstd::string constmight make the intended type more obvious to readers, especially since this is storing a project name which is a core concept.- auto const name(out.empty() ? project().root()[STR_NAME].Scalar() : out); + std::string const name(out.empty() ? project().root()[STR_NAME].Scalar() : out);

193-194: Consider making the thread pool timeout configurable.The hardcoded timeout of 10 seconds (
10000000microseconds) might not be suitable for all environments or test suites. Consider:
- Making this value configurable through application settings
- Using a constant or configuration value instead of a magic number
- ctp.finish(10000000); // 10 milliseconds + static constexpr auto DEFAULT_TIMEOUT_US = 10000000; // 10 seconds + ctp.finish(AppVars::INSTANCE().getThreadPoolTimeout(DEFAULT_TIMEOUT_US));

271-272: Enhance error message with more context.The error message when encountering an unsupported file type could be more helpful by including:
- The list of supported file types
- The current configuration context
- KEXCEPTION("Unable to handle artifact: \"" + lang + "\" - type is not in file list"); + std::string supported_types; + for (const auto& type : fs) { + if (!supported_types.empty()) supported_types += ", "; + supported_types += type.first; + } + KEXCEPTION("Unable to handle artifact: \"" + lang + "\" - supported types are: [" + supported_types + "]");src/maiken.cpp (2)
Line range hint
201-206: Enhance error message in catch blockThe current error message only shows the exception message and a generic "Possible super cycle detected" message. Consider including more context about what operation failed.
} catch (std::exception const& e) { - KLOG(ERR) << e.what(); - KEXIT(1, "Possible super cycle detected: " + project().dir().real()); + KLOG(ERR) << "Failed to resolve super project: " << e.what(); + KEXIT(1, "Failed to process super reference (possible cycle detected) in: " + project().dir().real()); }

109-109: 🛠️ Refactor suggestion
Consider keeping the reference type for better performance.
The change from reference to value type might introduce unnecessary string copies. Since Scalar() returns a std::string, and the value is only used for reading within the scope, using a const reference would be more efficient.
- auto const name(a.project().root()[STR_NAME].Scalar());
+ std::string const& name(a.project().root()[STR_NAME].Scalar());Likely invalid or redundant comment.
src/maiken/validation.cpp (1)
68-68: LGTM: Simple string comparison use case.
The change to value type is acceptable here as the string is only used for simple comparisons.
src/maiken.cpp (2)
196-196: LGTM: Good choice using auto const instead of auto const&
Using auto const is more efficient here as the YAML scalar value is small and copying avoids maintaining a reference to YAML's internal data structures.
Line range hint 196-232: LGTM: Robust error handling for super references
The code thoroughly validates super references by:
- Checking for self-references
- Validating file/directory existence
- Detecting cycles in the super chain
- Properly handling both file and directory cases
This makes the system more robust and provides clear error messages.

🛠️ Refactor suggestion
Maintain reference type for frequently used value.
The profile name is used multiple times in string comparisons and error messages. Using a value type here could lead to unnecessary copies.
- auto const p(profile[STR_NAME].Scalar());
+ std::string const& p(profile[STR_NAME].Scalar());📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
