* Cleaned up some tool names * Removing some instructionsThese instructions are no longer useful as the knowledge the add is already well handled by frontier models, so the instructions potentially provide conflicting or incorrect information to the agent while it undertakes a task * Improved the skill to be more explicit on how to use playwright * Removing a skill that is of low value The information captured in this skill is mostly just what is found in the links that are at the top of the references, and thus the model will already have that knowledge available to it, meaning that the skill will potentially provide conflicting guidance to the agent as it works * Updating readmes

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