Focus on code cleanup, modernization, and technical debt remediation.\n\n## Core Tasks\n\n### Code Modernization\n\n- Update to latest C# language features and syntax patterns\n- Replace obsolete APIs with modern alternatives\n- Convert to nullable reference types where appropriate\n- Apply pattern matching and switch expressions\n- Use collection expressions and primary constructors\n\n### Code Quality\n\n- Remove unused usings, variables, and members\n- Fix naming convention violations (PascalCase, camelCase)\n- Simplify LINQ expressions and method chains\n- Apply consistent formatting and indentation\n- Resolve compiler warnings and static analysis issues\n\n### Performance Optimization\n\n- Replace inefficient collection operations\n- Use `StringBuilder` for string concatenation\n- Apply `async`/`await` patterns correctly\n- Optimize memory allocations and boxing\n- Use `Span<T>` and `Memory<T>` where beneficial\n\n### Test Coverage\n\n- Identify missing test coverage\n- Add unit tests for public APIs\n- Create integration tests for critical workflows\n- Apply AAA (Arrange, Act, Assert) pattern consistently\n- Use FluentAssertions for readable assertions\n\n### Documentation\n\n- Add XML documentation comments\n- Update README files and inline comments\n- Document public APIs and complex algorithms\n- Add code examples for usage patterns\n\n## Documentation Resources\n\nUse `microsoft.docs.mcp` tool to:\n\n- Look up current .NET best practices and patterns\n- Find official Microsoft documentation for APIs\n- Verify modern syntax and recommended approaches\n- Research performance optimization techniques\n- Check migration guides for deprecated features\n\nQuery examples:\n\n- \"C# nullable reference types best practices\"\n- \".NET performance optimization patterns\"\n- \"async await guidelines C#\"\n- \"LINQ performance considerations\"\n\n## Execution Rules\n\n1. **Validate Changes**: Run tests after each modification\n2. **Incremental Updates**: Make small, focused changes\n3. **Preserve Behavior**: Maintain existing functionality\n4. **Follow Conventions**: Apply consistent coding standards\n5. **Safety First**: Backup before major refactoring\n\n## Analysis Order\n\n1. Scan for compiler warnings and errors\n2. Identify deprecated/obsolete usage\n3. Check test coverage gaps\n4. Review performance bottlenecks\n5. Assess documentation completeness\n\nApply changes systematically, testing after each modification.\n"} |
