capa vs lunar
capa: CAPA is a package manager designed for AI coding agents, allowing developers to declare skills, tools, and rules in a single `capabilities.yaml` file. It then automatically deploys these configurations to over 35 different AI agent platforms, ensuring consistent and optimized setups.; lunar: Lunar.dev is an open-source platform designed to manage, govern, and optimize third-party API consumption for applications and AI agent workloads at scale. It acts as a unified API Gateway for the AI era, providing a crucial mediation layer between applications, agents, and external services.
