## Description

This project is a shared technical specification and standard interface for dependency injection containers in PHP. It defines a common set of interfaces for retrieving services and dependencies, ensuring that different container implementations remain interoperable across the PHP ecosystem.

By establishing a standardized API for dependency retrieval, the project allows developers to create libraries that function with any compliant container. This prevents vendor lock-in and enables different container implementations to be swapped without requiring changes to the application code.

The specification covers the standardization of container interfaces and the definition of a uniform method for service resolution. This provides a consistent foundation for building custom service containers and developing interoperable packages.
