Purpose
This package is a configuration and setup utility that helps developers optimize Claude Code. It provides a collection of pre-built rules, agent templates, and 17 curated skills designed to automate development workflows and enhance AI coding capabilities.
Security Assessment
Overall Risk: Low. The automated code scan checked 8 files and found no dangerous patterns, hardcoded secrets, or requests for risky permissions. The tool relies heavily on external shell scripts for installation (via curl and PowerShell), which is standard but always requires a quick visual check before running. Since it is primarily a configuration hub, it installs a wide range of third-party dependencies (like skills from other developers). This means your overall security relies on the continued safety of that entire external ecosystem.
Quality Assessment
The project is actively maintained, with its most recent push occurring today. It uses the permissive MIT license and includes clear, detailed documentation. However, it currently has very low community visibility, with only 7 GitHub stars. This indicates that while the project is actively worked on by its creator, it has not yet been widely peer-reviewed or battle-tested by a large user base.
Verdict
Safe to use, but review the external dependencies it installs to ensure you trust the third-party authors.

Full Power-User Setup
The APM package gives you the foundation. For the complete harness — plugins, production settings, MCP gateway, lifecycle hooks, Langfuse observability, and cross-project intelligence — see SETUP.md.
| Priority | What You Get | Time |
|---|---|---|
| Essential | Skills + plugins + global config | 10 min |
| Recommended | + production settings + core hooks | 20 min |
| Power User | + MCP gateway + memory + switchboard + DSL | 45 min |
| Full Harness | Complete lifecycle automation | 90 min |
Self-Updating Knowledge Base
Say "update knowledge" or "research latest" and the skill will search official docs and community sources, appending findings to references/knowledge-base.md.
Usage
- Invoke directly:
/claude-code-mastery - Or let Claude auto-detect from context (e.g., "set up Claude Code for my project")
- Audit your setup: "audit my Claude Code configuration"
