I have been building Kasetto カセット a declarative skills manager for AI agents, written in Rust 🦀 Define your skills once in config, sync anywhere, keep team or your environment consistent.
Inspired by uv - what uv did for Python packages, Kasetto aims to do for AI skills and configs. There are good tools in this space already - Vercel Skills installs skills from a curated catalog, and Claude Plugins offer runtime integrations. Both work well for one-off installs, but neither gives you a declarative, version-controlled config.
Open source and community-driven. Would appreciate support and new contributions!
