Claude Code Mastery: Open-source config system adds persistent memory and curated skills to Claude Code CLI

What Claude Code Mastery does

Claude Code Mastery is an open-source configuration system designed to address persistent issues with Claude Code CLI. It solves four main problems: sessions starting from zero with no memory of previous conversations, auto-compact destroying critical context, lack of best practice enforcement, and manual setup requirements for every project.

Core features

• Perpetual Memory: A 6-file Memory Bank per project (via MCP) that persists across sessions and survives compaction. Claude reads all files at startup and writes updates after every task, preserving project context, architectural decisions, tech stack details, and progress.
• Smart Hooks (6 lifecycle events): SessionStart restores context automatically, PreCompact saves everything before compaction, PreToolUse blocks dangerous commands (rm -rf, force push), and UserPromptSubmit reminds about skills and Memory Bank on every message.
• 26+ Curated Skills from 5 marketplaces: Superpowers (TDD, debugging, planning, code review, parallel agents), Trail of Bits (security analysis, differential review, supply chain audit), Context Engineering Kit (spec-driven dev, kaizen, reflexion), Shield (automated pentesting, SAST, secrets scanning), plus 3 custom skills (architect-review, context-guardian, production-audit).
• Zero-Config Launcher: Type claude in any project directory. Memory Bank, .gitignore, session logs, and diagnostics are set up automatically on first run.
• Cross-Platform: Supports macOS (zsh), Linux (bash), and Windows (PowerShell) with one installer.
• Customizable: Interactive installer, language selection (en/pt-BR/es), project presets (Node.js, Python, PHP, monorepo), and selective plugin installation.

Testing and installation

The system includes 103 static tests plus 138 Docker integration tests (Ubuntu/Bash, Ubuntu/Zsh, Alpine). It achieved a Shield security score of 100/100 and uses GitHub Actions CI on every push.
