Custom skills are reusable instruction sets you build using frontmatter-based SKILL.md structures. Define your skill's logic, parameters, and output format in the metadata block, then reference it in your Claude Code workflows to automate specific tasks without writing repetitive prompts.

Skills are reusable instruction sets for complex workflows. Commands are individual actions you invoke directly. Hooks are automated triggers that execute code at specific events—like after file edits—without manual invocation, enabling seamless workflow automation.

The Model Context Protocol lets you configure MCP servers to connect Claude Code to databases, APIs, and external tools. Define server endpoints and authentication in your MCP configuration, then Claude can interact with those resources as part of your customized workflows.

Yes. Plugin structures let you package multiple skills, commands, and agents together with metadata for distribution. Use the plugin marketplace format to define dependencies, components, and entry points, making it easy for teams to share and reuse your customizations.

Basic familiarity with Claude Code fundamentals helps. Hooks require understanding event patterns and hook definition syntax, but you don't need advanced programming skills—focus on specifying when hooks run and what actions they execute.

Hooks running after file edits can automatically format code, run linters, execute tests, or trigger build processes. Define the post-edit event trigger and specify the commands or skills to run, creating consistent automation without manual intervention.
