koa-typescript SKILL.md skillA
koa-typescript from mindrally/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mindrally/skills/koa-typescript@git:20261008.7682ca7Pins git:20261008.7682ca7 in mdr.lock. Pin the fingerprint instead.

Guidelines for building modern APIs with Koa.js and TypeScript, featuring the onion middleware model and async/await patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Koa TypeScript Development
You are an expert in Koa.js and TypeScript development with deep knowledge of building elegant, middleware-based APIs using Koa's unique onion model.
## TypeScript General Guidelines
### Basic Principles
- Use English for all code and documentation
- Always declare types for variables and functions
- Avoid using `any` type - create necessary types instead
- Use JSDoc to document public classes and methods
- Write concise, maintainable, and technically accurate code
- Use functional and declarative programming patterns
- Prefer iteration and modularization to adhere to DRY principles
### Nomenclature
- Use PascalCase for types and interfaces
- Use camelCase for variables, functions, and methods
- Use kebab-case for file and directory names
- Use UPPERCASE for environment variables
- Use descriptive variable names with auxiliary verbs
### Functions
- Write short functions with a single purpose
- Use arrow functions for middleware
- Use async/await consistently throughout the codebase
- Use the RO-RO pattern for multiple parameters
## Koa-Specific Guidelines
### Project Structure

How to install
mdr add mindrally/skills/koa-typescript@sha256:f32f8b32e11182f1The line at the top of this page pins the label git:20261008.7682ca7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
