Claude — Claude Code
15 courses for using Claude Code on a real repository: context, planning, implementation, testing, Git, Skills, subagents, Hooks, MCP, security, and governance.
Claude Code is aimed primarily at developers, Software Engineers, Tech Leads and professionals working on real codebases. The pathway teaches Claude Code as a software engineering assistant rather than a simple snippet generator. By the end of the pathway, you will be able to understand a repository, prepare a change plan, implement and test modifications, work with Git and code review, use Skills, subagents, Hooks and MCP, and secure and govern Claude Code in a professional environment.
This Claude Code pathway is designed for real repository work and verifiable software changes, not just code snippet generation. Each course includes 10 interactive lessons covering repository understanding, context and planning, implementation, testing, Git and code review, Skills, subagents, Hooks, MCP, security, and governance. Version-sensitive practices are flagged so commands, options, and integrations can be rechecked against current official documentation. Indicative duration: 3 to 5 hours per course, depending on your level and how far you explore each topic.
🎓 15 courses • 📚 150 interactive lessons • ⏱️ 45 to 75 hours of conversational learning
