    Project mention: Lessons from Building My First Claude Skill - a code tutorial generator | dev.to | 2026-05-07

    Sometime around last year, I started a project (Waver) that would generate tutorials from a codebase. Easy to follow tutorials in pure markdown + mermaid diagrams, so any person could be onboarded with ease, projects could add it to project pipelines etc. The idea was simple, I chose Langchain4J to do this. If this wasnt amusing enough, I also ended up creating JGraphlet while trying to optimize the performance of LLM communication.
