Create ASP.NET Minimal API endpoints with proper OpenAPI documentation

  • Tasks that involve OpenAPI specifications
  • SKILL.md covers API Organization, Request and Response Types, Type Handling and OpenAPI Documentation
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve REST APIs

What it does

Aspnet Minimal API Openapi is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Create ASP.NET Minimal API endpoints with proper OpenAPI documentation

Its SKILL.md is about 440 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 Backend & APIs, covering OpenAPI specifications and REST APIs. It works with OpenAPI and ASP.NET Core. 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 OpenAPI specifications
  • Tasks that involve REST APIs

Example prompts

  • “/aspnet-minimal-api-openapi”

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

Aspnet Minimal API Openapi loads about 439 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~439

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.

Create ASP.NET Minimal API endpoints with proper OpenAPI documentation

ASP.NET Minimal API with OpenAPI

Your goal is to help me create well-structured ASP.NET Minimal API endpoints with correct types and comprehensive OpenAPI/Swagger documentation.

API Organization

  • Group related endpoints using MapGroup() extension
  • Use endpoint filters for cross-cutting concerns
  • Structure larger APIs with separate endpoint classes
  • Consider using a feature-based folder structure for complex APIs

Request and Response Types

  • Define explicit request and response DTOs/models
  • Create clear model classes with proper validation attributes
  • Use record types for immutable request/response objects
  • Use meaningful property names that align with API design standards
  • Apply [Required] and other validation attributes to enforce constraints
  • Use the ProblemDetailsService and StatusCodePages to get standard error responses

Type Handling

  • Use strongly-typed route parameters with explicit type binding
  • Use Results<T1, T2> to represent multiple response types
  • Return TypedResults instead of Results for strongly-typed responses
  • Leverage C# 10+ features like nullable annotations and init-only properties

OpenAPI Documentation

  • Use the built-in OpenAPI document support added in .NET 9
  • Define operation summary and description
  • Add operationIds using the WithName extension method
  • Add descriptions to properties and parameters with [Description()]
  • Set proper content types for requests and responses
  • Use document transformers to add elements like servers, tags, and security schemes
  • Use schema transformers to apply customizations to OpenAPI schemas
