It's designed for scientists, researchers, and developers worldwide who want to build or enhance AI agents for scientific work, compatible with major AI platforms and the open Agent Skills standard.

Archify is an agent skill that transforms plain English descriptions of systems into beautiful, interactive HTML diagrams. It solves the problem of creating and maintaining accurate, up-to-date architecture, workflow, and sequence diagrams by generating them directly from conversation. It's for developers, architects, and teams who need to quickly visualize, share, and verify system designs with motion, exploration, and crisp export built-in.

Ponytail is a ruleset for AI coding agents that enforces a 'lazy senior dev' mindset, drastically reducing over-engineering. It makes your agent stop at the first, simplest working solution—reusing existing code, leveraging standard libraries, and avoiding speculative features. It's for developers who want their AI assistants to produce minimal, maintainable, and robust code without unnecessary complexity.

claude-obsidian is a free Claude Code plugin that automates your personal knowledge management in Obsidian. It solves the maintenance problem of traditional second brains by reading your sources and automatically writing, linking, and filing notes into a connected knowledge graph. It's for knowledge workers, researchers, and anyone tired of manually maintaining their note vaults, offering a self-sustaining system of plain Markdown files you own.

Awesome Agent Skills is a curated, production-ready repository of over 1000+ skills for AI agents and coding assistants.
