Everything Claude Code (ECC)

What it is

Everything Claude Code (ECC) is a comprehensive performance optimization system designed for AI agent harnesses, primarily Claude Code. It is not just a configuration pack but a complete ecosystem of specialized agents, skills, hooks, and rules evolved from intensive daily production use.

What problem it solves

It bridges the gap between a raw AI CLI and a production-ready autonomous engineering environment. ECC addresses context window management, security risks, memory persistence across sessions, and language-specific coding standards through automated enforcement and optimized prompt engineering.

Where it fits in the stack

Category: AI Assistants & Knowledge / Developer Tooling

Typical use cases

  • Autonomous Engineering: Leveraging specialized subagents (Architect, Planner, TDD Guide) for complex feature implementation.
  • Security Auditing: Using the integrated AgentShield to scan configurations for secrets and injection risks.
  • Continuous Learning: Automatically extracting patterns from development sessions into reusable "instincts" and skills.
  • Multi-Agent Orchestration: Managing complex workflows across multiple services using PM2 and collaborative planning commands.

Key Components

  • Subagents (48+): Specialized personas like typescript-reviewer, sql-auditor, and build-error-resolver for delegation.
  • Skills (182+): Domain-specific workflow definitions ranging from frontend-slides to market-research.
  • Hooks Runtime: Trigger-based automations that fire on tool events (e.g., auto-formatting after an edit or secret detection before prompt submission).
  • Rules (34+): Standardized, language-specific guidelines (TypeScript, Python, Go, Swift, PHP) that ensure consistency across the codebase.

Ecosystem Tools

AgentShield — Security Auditor

A dedicated auditor that scans Claude Code configurations (.claude/ directory) for vulnerabilities. It uses adversarial reasoning (Red Team/Blue Team agents) to evaluate protection layers and synthesize risk assessments.

Skill Creator

Analyzes local Git history to automatically generate SKILL.md files and instinct collections, allowing the agent to "learn" from the existing codebase patterns.

Getting started

# Add the marketplace
/plugin marketplace add https://github.com/affaan-m/everything-claude-code

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

Option 2: Manual Installation

git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# Copy agents to your configuration
cp agents/*.md ~/.claude/agents/

Technical details

  • Cross-Platform Support: Rewritten in Node.js for compatibility across Windows, macOS, and Linux.
  • Adapter Pattern: Uses a DRY (Don't Repeat Yourself) adapter to share hook scripts between Claude Code and Cursor.
  • Token Optimization: Includes recommended settings to reduce costs (e.g., setting MAX_THINKING_TOKENS) without sacrificing reasoning quality.
  • Memory Persistence: Implements SQLite-backed state stores to track session history and skill evolution.
