Everything Claude Code

The complete collection of Claude Code configs from an Anthropic hackathon winner.

Production-ready agents, skills, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products.

The Guides

This repo is the raw code only. The guides explain everything.

Start Here: The Shorthand Guide

The Shorthand Guide to Everything Claude Code

The foundation - what each config type does, how to structure your setup, context window management, and the philosophy behind these configs. Read this first.

Then: The Longform Guide

The Longform Guide to Everything Claude Code

The advanced techniques - token optimization, memory persistence across sessions, verification loops & evals, parallelization strategies, subagent orchestration, and continuous learning. Everything in this guide has working code in this repo.

Topic	What You'll Learn
Token Optimization	Model selection, system prompt slimming, background processes
Memory Persistence	Hooks that save/load context across sessions automatically
Continuous Learning	Auto-extract patterns from sessions into reusable skills
Verification Loops	Checkpoint vs continuous evals, grader types, pass@k metrics
Parallelization	Git worktrees, cascade method, when to scale instances
Subagent Orchestration	The context problem, iterative retrieval pattern
