claude-howto: How to Combine Claude Code Features: An 11-Hour Roadmap

After installing Claude Code, using individual features in isolation often means failing to leverage its full potential. This guide visually explains how to combine slash commands, hooks, subagents, and MCP servers to build automation pipelines. Unlike the feature lists provided in the official documentation, it shows how each feature works internally using Mermaid diagrams.

It goes beyond simple conceptual explanations by providing practical templates that can be applied directly to projects. You only need to copy and paste the configuration files for scenarios required in real-world work, such as code review pipelines, team onboarding, and CI/CD automation. It is designed to help users from beginner to advanced level become proficient in 11 to 13 hours by following a step-by-step learning path consisting of 10 modules.

To enhance learning effectiveness, it supports built-in self-assessment features. Running specific commands within Claude Code diagnoses your current proficiency level and presents a customized roadmap to fill in any gaps. You can check your understanding by taking quizzes after studying each module, and it is released under the MIT license, allowing free use in personal and enterprise projects.
