How to Set Up and Use Claude Code Mastery
Claude Code Mastery is a comprehensive reference and template repository that teaches developers how to get the most out of Claude Code through structured CLAUDE.md files, deterministic hook enforcement, custom slash commands, reusable skills, and MCP server integrations. It covers the full spectrum from global security gatekeeping via CLAUDE.md to hook-enforced rules that cannot be overridden by LLM context. Developers use it to eliminate configuration drift across projects and enforce quality gates that suggestions alone cannot guarantee.
Prerequisites
- Claude Code installed (https://code.claude.com)
- Python 3.8 or later (required for Python-based hooks like block-secrets.py)
- jq installed (for JSON parsing in shell hooks)
- Git to clone the repository and copy templates
- A Unix-like shell environment (macOS or Linux; Windows users should use WSL)
Clone the repository
Clone the claude-code-mastery repository to get all templates, hooks, skills, and commands locally.
git clone https://github.com/TheDecipherist/claude-code-mastery.git
cd claude-code-masteryInstall hooks into your Claude config
Copy the provided hook scripts to your ~/.claude/hooks directory and make shell scripts executable. Hooks enforce rules deterministically — unlike CLAUDE.md which the LLM may override, hooks always run.
mkdir -p ~/.claude/hooks
cp hooks/block-secrets.py ~/.claude/hooks/
cp hooks/block-dangerous-commands.sh ~/.claude/hooks/
cp hooks/end-of-turn.sh ~/.claude/hooks/
chmod +x ~/.claude/hooks/*.shConfigure settings.json with hook definitions
Copy the provided settings template to ~/.claude/settings.json. If you already have a settings.json, manually merge the hooks section. This wires up which hooks fire on which Claude Code events (PreToolUse, PostToolUse, Stop).
cp templates/settings.json ~/.claude/settings.jsonSet up your global CLAUDE.md
Copy the global CLAUDE.md template to ~/.claude/CLAUDE.md and customize it with your name, preferences, and project conventions. This file is inherited by all Claude Code sessions.
cp templates/global-claude.md ~/.claude/CLAUDE.md
$EDITOR ~/.claude/CLAUDE.mdInstall skills
Copy the reusable skills (commit-messages, security-audit) to your ~/.claude/skills directory so they are available as slash commands in every Claude Code session.
mkdir -p ~/.claude/skills
cp -r skills/* ~/.claude/skills/Verify the installation
Start Claude Code and check that hooks and skills are recognized. Use /hooks to list loaded hooks and /skills to list available skills.

Client configuration
The repository configures Claude Code via settings.json hooks rather than a traditional MCP JSON block. Here is the structure of the settings.json hook configuration.
{
"hooks": {
"PreToolUse": [
{
"matcher": "Write|Edit",
"hooks": [
{"type": "command", "command": "python3 ~/.claude/hooks/block-secrets.py"}
]
}
],
"Stop": [
{
"hooks": [
{"type": "command", "command": "~/.claude/hooks/end-of-turn.sh"}
]
}
]
}
}Prompts to try
Use the installed slash commands and skills in your Claude Code sessions to enforce quality gates and automate workflows.
- "/new-project" to scaffold a new project following your CLAUDE.md conventions
- "/security-check" to run a security audit on the current codebase
- "/pre-commit" to run quality gates before committing
- "/commit-messages" to generate conventional commit messages for staged changesTroubleshooting Claude Code Mastery
Hooks do not appear to be running even though they are in ~/.claude/hooks
Hooks must be registered in settings.json under the correct event key (PreToolUse, PostToolUse, Stop). Simply placing scripts in the hooks folder is not enough — check that settings.json has the full hooks section and that Claude Code has been restarted.
block-dangerous-commands.sh or end-of-turn.sh fails with a permission error
Run 'chmod +x ~/.claude/hooks/*.sh' to ensure all shell hooks are executable. Python hooks (.py) do not need the executable bit but require python3 to be in PATH.
Skills are not showing up with /skills command
Each skill must be a directory containing a SKILL.md file inside ~/.claude/skills/. Verify the directory structure with 'ls -la ~/.claude/skills/' and make sure you copied the skill subdirectories, not just the SKILL.md files.
