Customize
Skills & Store
Install extensions from the Quack Store, and invoke Claude Code skills with /.
Quack Store
A small catalog of external tools Quack can install for you — Pinky (knowledge search, see Second Brain) and Skill Trainer, so far. Quack handles the install command itself; you just click install.
Claude Code skills
Skills — folders with a SKILL.md — are discoverable from the composer's
/ menu. Quack looks in your project's .claude/skills/, your global
~/.claude/skills/, and a few built-in ones Quack ships with. Type / and
start typing to fuzzy-search across all of them.
Managing skills
Skills can be browsed, edited, or created from the Agent Customizations panel's Skills tab, with the same fuzzy search as the composer menu.
