I really liked the approach and idea that you enforce discipline for your agent through a skill-based workflow. Even though coding agents (copilot included) have become a lot better at natively handling complex tasks, they still wander off and lose track of things. I really liked how superpowers fixed this and how it enabled long-running sessions without the agent losing its "focus". So I decided to build a Copilot tailored skill suite around the core idea of superpowers. I didn't just want to port superpowers to Copilot, I took inspiration from it and improved on it. JDS enforces a strict think -> plan -> execute pipeline where nothing gets skipped. It leverages Copilot's built-in sql todo dependencies and provides a live task graph visualizer which helps visualize the agentic workflow and its parallelism. Curious whether others have tried similar approaches, and what's worked or not.

This library solves the problem of ensuring that sensitive endpoints do not trigger side-effects multiple times - this is especially useful for any endpoints that handle financial operations. Currently, the library supports Spring MVC (Servlet-based) applications and MySQL and PostgreSQL with jdbc regarding storage backends. It is very simple to integrate, all that you have to do is add @Idempotent to any endpoints that need idempotency.

Full explanation of the functionalities and configuration is available in the readme of the repository. Repository : https://github.com/josipmusa/idempotency4j

I would love any feedback or review regarding the implementation - also, any recommendation is welcome.
