Ten modules replace tab-hopping with a course
Claude How To puts 10 modules in a deliberate order: commands and memory first, followed by checkpoints, CLI use, skills, hooks, MCP, subagents, advanced features, and plugins. Anthropic's documentation works as a reference when you already know the feature name. This repository is better at answering a beginner's earlier question: what should I learn next? Its roadmap has a self-assessment, entry points for three experience levels, exercises, and checks for understanding.
The complete path is estimated by the project at 11 to 13 hours. That figure is curriculum guidance, not a result from our lab. A shorter start copies one command into .claude/commands and a sample CLAUDE.md into a project. This is the guide's best move. You encounter a working file early, then read the explanation with something concrete in front of you.
The 669 files are examples to audit, not a finished configuration
Our measured checkout contained 669 files, about 13,428 lines of source, and occupied 15.7 MB. It includes sample commands, memory files, skill folders, subagent prompts, MCP JSON, hook scripts, and plugin bundles. There are also Mermaid diagrams and an EPUB builder. That range gives a team plenty of material for a workshop, especially when official feature pages feel disconnected from one another.
Copying the entire tree would be reckless. Hooks can run shell commands, MCP configurations can connect Claude Code to external systems, and several examples expect credentials in environment variables. The README tells readers to avoid hardcoded secrets and test configurations locally. Keep that boundary. A sample shows a file shape and an intended workflow; it knows nothing about your repository permissions, release gates, or secret store.
What happened when we ran it
Our sandbox installed commit 4f57038 in 24 seconds, adding 35 packages and consuming 37 MB on disk. The build completed in 8 seconds. We used a fresh unprivileged Debian container with 3 CPUs, 8 GB of RAM, Python 3.12, and no secrets. Pip-audit reported 0 known vulnerabilities in the installed environment. These results cover the repository tooling, not the correctness of every lesson or copied configuration.
Tests were skipped because our runner found no test script or target. The same scan found 4 CI workflow files, no Dockerfile, and no tests directory. The README has a testing section with pytest commands aimed at scripts/tests/, but our run did not execute them and cannot claim a passing suite. That mismatch is worth checking before changing the builders: use the commands the repository currently exposes, and confirm that their referenced paths exist at the commit you pin.
Issue 176 catches two configuration errors that change behavior
Open issue 176 reports 2 errors in the skills lesson. First, it says the guide reverses personal and project skill precedence. Second, it says skillOverrides is shown as a string that changes which duplicate skill wins, while the real setting is an object controlling visibility. The report points to the affected files and official skills documentation. These are consequential mistakes because either one can make Claude Code load or display a skill differently from what the reader expects.
The report also shows useful peer review. It traces the precedence error to an earlier accuracy pass, names translated copies needing the same correction, and explains why a related quiz change would have spread the mistake. Still, readers carry the verification burden while the issue remains open. Check official docs before adopting a permission mode, hook event, settings key, or precedence rule. The course explains how the parts connect; it should not be your only source for volatile behavior.
A September 30 push matters more than the June release tag
GitHub showed 41,728 stars and 31 open issues and pull requests when fetched. The repository was pushed on September 30, 2026, and a merged pull request that day synced the material to Claude Code v2.1.285. Other September changes updated the guide for v2.1.283, v2.1.278, and v2.1.257. Taken together, the dates show active maintenance and the burden created by tracking a fast-moving product.
The latest GitHub Release was v2.1.160 from June 2, 2026. That older tag does not establish abandonment because commits and issue work continued through September. It does make the Releases page a poor place to choose teaching material. Pin a commit, record which Claude Code version your team uses, and inspect upstream changes before refreshing an internal copy.
The course is strongest when each copied file stays small
The 10-module sequence is the reason to choose Claude How To over a directory of unrelated tips. Beginners get an order, and experienced users get examples they can discuss with a team. The repository also covers enough surface area to show how memory, commands, skills, agents, hooks, plugins, and MCP affect one another. That systems view is hard to get from isolated reference pages.
Breadth creates the central risk. Our 24-second install and 8-second build make the repository cheap to inspect, but the skipped test step supplies no assurance about prose claims or settings copied into your machine. Adopt one behavior at a time. Keep permissions narrow, inspect every command, and place the official documentation beside any lesson that can expose credentials or change which instructions Claude Code follows.
