Slash Cards turns the Claude Code slash command catalog into a focused, beautiful study app. Quiz yourself two ways: see a command and pick the right description, or read a description and pick the right /command. Built for developers who live in Claude Code and want to actually remember what /compact, /resume, /security-review, /hooks, and the rest of the catalog do.
