Maintained by K-Dense-AI

A large library of agent skills for science. Each skill has a SKILL.md with its workflow and covers a scientific package or one of 80+ scientific and financial databases. It works with Claude Code, Codex, Cursor and other agents.

Pros & cons

Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.

Cons
