Skill library

The ready-made skills in Customize > Skills > Browse the library are adapted from openly licensed repositories published by Anthropic. We changed them for AIOAIA: our own names, titles and descriptions; steps that only work with another app's tools, commands or files removed; an opening paragraph for chat use and, on legal and finance skills, a line that answers are not professional advice. They are not made or endorsed by Anthropic, and AIOAIA is not affiliated with Anthropic.
