A library · GitHub repos by topic
Repos
These are GitHub repos I find useful. I file each one under the topics it belongs to, the way notes link in an Obsidian vault: a repo can sit under several topics, and a topic gathers several repos, so you can come in from either side.
Skills and plugins run code on your machine, so read a repo’s SKILL.md and its scripts before you install it.
Stars, languages, licences and dates are GitHub’s, read on Oct 30, 2026. Jump to the graph.
