Courses & Tutorials

Learn Claude Code — Build an AI Agent from Scratch

github.com/shareAI-lab/learn-claude-code | Interactive Platform: learn.shareai.run

A 12-lesson course that teaches Claude Code internals by building a complete AI coding agent (s_full.py) step by step. Each lesson builds on the previous one:

Section	Topics
Foundation (1-3)	Agent Loop basics, Bash Tool, Tool registration & scheduling
Intermediate (4-6)	Sub-agent task decomposition, Skills dynamic loading, context compression, task persistence, async execution
Advanced (7-9)	Multi-agent teams, custom inter-agent protocols, worktree isolation
Final	Combine all 12 lessons into `s_full.py` — a complete AI coding agent

The interactive platform at learn.shareai.run provides a visual learning experience (recommended over just reading the repo). Chinese README available at README-zh.md.

Why this matters: After completing this course, you understand what Claude Code is actually doing under the hood — Agent Loop, Tool system, Skills, Subagents — not just how to use it. This maps directly to the Claude Certified Architect exam domains.

Best Practices for Building Skills

Practice	Detail
Start with SKILL.md	Skills are not just Markdown — they’re assets, templates, file layouts, flexible structures
Phase-driven design	Break skills into checkpointed phases, not one giant prompt
Mental model first	Define the thinking pattern before the steps
Hook integration	Use hooks for automatic verification, not prompt suggestions
Measure & iterate	Most skills start as a few lines and evolve as edge cases appear

“Skills are powerful and flexible tools, but still early stage. Treat these as a collection of useful tips, not an authoritative guide. The best way to understand skills is to start, experiment, and see what works.”

How LearnAI Team Could Use This

Discover existing skills before building new ones — check marketplaces and community lists first.
Use the official skill creation docs and frameworks to build LearnAI-specific skills (wiki generation, course review, research synthesis).
Evaluate skills by the 9-type taxonomy to ensure the team has coverage across workflow needs.

Real-World Use Cases

Finding and installing research-focused skills (literature review, citation management, paper analysis).
Creating custom team skills for recurring workflows (wiki entry generation, exam auditing, slide creation).
Browsing community skill directories for inspiration before building from scratch.
