The Marketplace

Skills you can install

The handbook tells an AI how I work. These package it so an AI can just do it. Each skill is an installable Claude Code capability, from planning and scaffolding to writing, quality checks, and session hygiene, that drops into your agent and runs the way I would.

How to install

Skills install from a git marketplace, not a download. In Claude Code, add the marketplace once and install the plugin, then run any skill by name:

/plugin marketplace add Selwynuy/selwynuy
/plugin install selwyn-handbook@selwyn-handbook
# then run: /selwyn-handbook:<name>

Every card has a one-click install command on its detail page. Agents can read the index at /llms.txt, or browse the whole handbook these are drawn from.
