How These Resources Work Together

These 14 repos form a layered ecosystem. Understanding the layers helps you build your setup systematically:

Layer 1 — Discovery (Awesome Claude Code, Awesome Toolkit, Awesome MCP Servers): Find what exists. Browse these first to understand the landscape. Time investment: 1 hour.

Layer 2 — Behavior (Karpathy Skills, SuperClaude): Change how Claude operates. These modify Claude’s reasoning and workflow patterns. Time investment: 10 minutes to install, ongoing refinement.

Layer 3 — Configuration (Claude Code Templates, Awesome LLM Apps): Install pre-built components. These give you agents, commands, hooks, and application starting points. Time investment: 30 minutes for initial setup.

Layer 4 — Learning (Claude Howto, Ultimate Guide, System Prompts, Docs Mirror): Deepen your understanding. These make you more effective over time. Time investment: 2-20 hours depending on depth.

Layer 5 — Operations (ccusage, Task Master): Manage costs and tasks. These keep your Claude Code usage efficient and organized. Time investment: 10 minutes to set up, 5 minutes weekly to review.
