The Guides

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

| 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 |

Cross-Platform Support

This plugin now fully supports Windows, macOS, and Linux. All hooks and scripts have been rewritten in Node.js for maximum compatibility.

Package Manager Detection

The plugin automatically detects your preferred package manager (npm, pnpm, yarn, or bun) with the following priority:

1. Environment variable: CLAUDE_PACKAGE_MANAGER
2. Project config: .claude/package-manager.json
3. package.json: packageManager field
4. Lock file: Detection from package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
5. Global config: ~/.claude/package-manager.json
6. Fallback: First available package manager

To set your preferred package manager:

# Via environment variable
export CLAUDE_PACKAGE_MANAGER=pnpm

# Via global config
node scripts/setup-package-manager.js --global pnpm

# Via project config
node scripts/setup-package-manager.js --project bun

# Detect current setting
node scripts/setup-package-manager.js --detect

Or use the /setup-pm command in Claude Code.

Installation

Option 1: Install as Plugin (Recommended)

The easiest way to use this repo - install as a Claude Code plugin:

# Add this repo as a marketplace
/plugin marketplace add affaan-m/everything-claude-code

# Install the plugin
/plugin install everything-claude-code@everything-claude-code

Or add directly to your ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "everything-claude-code": {
      "source": {
        "source": "github",
        "repo": "affaan-m/everything-claude-code"
      }
    }
  },
  "enabledPlugins": {
    "everything-claude-code@everything-claude-code": true
  }
}

This gives you instant access to all commands, agents, skills, and hooks.

Key Concepts

Agents

Subagents handle delegated tasks with limited scope. Example:

---
name: code-reviewer
description: Reviews code for quality, security, and maintainability
tools: Read, Grep, Glob, Bash
model: opus
---

You are a senior code reviewer...

Skills

Skills are workflow definitions invoked by commands or agents:

# TDD Workflow

1. Define interfaces first
2. Write failing tests (RED)
3. Implement minimal code (GREEN)
4. Refactor (IMPROVE)
5. Verify 80%+ coverage

Hooks

Hooks fire on tool events. Example - warn about console.log:

{
  "matcher": "tool == \"Edit\" && tool_input.file_path
