Hi HN, I built the SigmaLifting app a while ago. Seeing the recent rise in agentic tools, I decided to extract its core engine into a CLI using the same underlying protocol. Powerlifting programming is really just structured data. The CLI lets your agents manage it entirely in the terminal using plain JSON for local storage, with built-in validation. The main idea is that it separates the program (the reusable template) from the process (your actual workout logs). Since everything is just JSON, it’s easy to pipe your training history straight into a script or an LLM for analysis. Would love to hear what you guys think!
