2. Context Management — token budgeting, compaction, context-mode plugin
3. MCP Server Stack — gateway architecture, tiered recommendations
4. Settings/Permissions/Hooks — production-ready templates, lifecycle hooks
5. Agents & Subagents — orchestration, wave execution, agent teams
6. Skills & Plugins — ecosystem, 17 curated skills, plugin stack
7. CI/CD & Automation — headless mode, GitHub Actions, worktrees

| Agent | Purpose | |-------|---------| | code-reviewer | Post-change quality review (bugs, security, coverage) | | security-auditor | Auto-spawned for auth/payment/identity code | | doc-writer | Technical documentation with project style matching |

Hooks (reference patterns in hooks.json)

| Hook | Event | What It Does | |------|-------|-------------| | git-push-guard | PreToolUse | Forces commit review before push | | auto-format-* | PostToolUse | Formats TS/Python/C# files on write | | context-renewal | PostCompact | Re-orients after compaction | | type/build-check | Stop | Catches errors when Claude stops |

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](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"
