Slash commands, hooks, subagents, skills and plugins

Learn the 5 ways to make Claude Code yours: custom slash commands (saved prompts like /new-endpoint), hooks (scripts that run automatically, e.g. format and lint after every edit, block edits to .env), subagents (specialists with their own instructions and tools, e.g. a test-writer or code-reviewer), skills (folders of instructions and scripts Claude loads when relevant), plugins (bundles of all of these you can install from a marketplace or share with your team).
