Which frameworks are currently supported?

The ln-770 skill specifically supports .NET (ASP.NET Core) and Python (FastAPI) environments.

How do I integrate the generated code into my project?

The skill generates a centralized extension method (for .NET) or a middleware initializer (for Python) and provides clear instructions on how to call it from your main entry point.

Does this skill overwrite my existing configuration?

No, the skill includes a detection phase that identifies existing setups for logging, CORS, and other concerns, marking them to be skipped to ensure idempotency.

What specific logging libraries does it implement?

It typically configures Serilog for .NET projects and structlog for Python projects to provide structured, production-grade logging.

API Development

Standardizes backend infrastructure by automating the setup of logging, error handling, CORS, health checks, and API documentation for .NET and Python projects.

This skill acts as a domain coordinator for project bootstrapping, automating the implementation of essential 'boilerplate' services that are often tedious to set up manually. It intelligently detects whether a project is using ASP.NET Core or FastAPI, audits existing configurations to ensure idempotency, and orchestrates specialized workers to implement production-ready logging, global exception handling, CORS policies, health monitoring, and Swagger/OpenAPI documentation. By generating a unified service registration entry point, it ensures a clean, maintainable architecture across your entire development workflow.
