What it does

In the author's own words, from each skill's SKILL.md — showing the first 30 of 105 files.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
