Install
Skills CLI
npx skills add Fmarzochi/EGC
Asks which skills and agents to install. Just one: npx skills add Fmarzochi/EGC --skill agent-introspection-debugging — add -g for every project.
Claude Code
git clone https://github.com/Fmarzochi/EGCcp -r "EGC/.agents/skills/agent-introspection-debugging" ~/.claude/skills/
Copies the agent-introspection-debugging skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add Fmarzochi/EGC
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does

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.
