At a glance

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Dotnet Design Pattern Review is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Review the C/.NET code for design pattern implementation and suggest improvements.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Design patterns. It works with .NET and C#. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Tasks that involve Design patterns

Example prompts

  • “/dotnet-design-pattern-review”

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dotnet Design Pattern Review loads about 821 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 316 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~821

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.NET/C# Design Pattern Review

Review the C#/.NET code in ${selection} for design pattern implementation and suggest improvements for the solution/project. Do not make any changes to the code, just provide a review.

Required Design Patterns

  • Command Pattern: Generic base classes (CommandHandler<TOptions>), ICommandHandler<TOptions> interface, CommandHandlerOptions inheritance, static SetupCommand(IHost host) methods
  • Factory Pattern: Complex object creation service provider integration
  • Dependency Injection: Primary constructor syntax, ArgumentNullException null checks, interface abstractions, proper service lifetimes
  • Repository Pattern: Async data access interfaces provider abstractions for connections
  • Provider Pattern: External service abstractions (database, AI), clear contracts, configuration handling
  • Resource Pattern: ResourceManager for localized messages, separate .resx files (LogMessages, ErrorMessages)

Review Checklist

  • Design Patterns: Identify patterns used. Are Command Handler, Factory, Provider, and Repository patterns correctly implemented? Missing beneficial patterns?
  • Architecture: Follow namespace conventions ({Core|Console|App|Service}.{Feature})? Proper separation between Core/Console projects? Modular and readable?
  • .NET Best Practices: Primary constructors, async/await with Task returns, ResourceManager usage, structured logging, strongly-typed configuration?
  • GoF Patterns: Command, Factory, Template Method, Strategy patterns correctly implemented?
  • SOLID Principles: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion violations?
  • Performance: Proper async/await, resource disposal, ConfigureAwait(false), parallel processing opportunities?
  • Maintainability: Clear separation of concerns, consistent error handling, proper configuration usage?
  • Testability: Dependencies abstracted via interfaces, mockable components, async testability, AAA pattern compatibility?
  • Security: Input validation, secure credential handling, parameterized queries, safe exception handling?
  • Documentation: XML docs for public APIs, parameter/return descriptions, resource file organization?
  • Code Clarity: Meaningful names reflecting domain concepts, clear intent through patterns, self-explanatory structure?
  • Clean Code: Consistent style, appropriate method/class size, minimal complexity, eliminated duplication?

Improvement Focus Areas

  • Command Handlers: Validation in base class, consistent error handling, proper resource management
  • Factories: Dependency configuration, service provider integration, disposal patterns
  • Providers: Connection management, async patterns, exception handling and logging
  • Configuration: Data annotations, validation attributes, secure sensitive value handling
  • AI/ML Integration: Semantic Kernel patterns, structured output handling, model configuration

Provide specific, actionable recommendations for improvements aligned with the project's architecture and .NET best practices.
