Everything Claude Code — The Plugin That Supercharges Your AI Agent
If you use Claude Code on a daily basis, you need to know about Everything Claude Code (ECC) — a plugin that has already accumulated over 104,000 stars on GitHub and won the Anthropic Hackathon.
What is Everything Claude Code?
Everything Claude Code is a complete performance optimization system for AI agents like Claude Code, Cursor, OpenCode, and Codex. It works as a configuration framework that adds skills, instincts, memory, security, and research-first development to your workflow.
Key Features
Specialized Agents
ECC comes with 28 specialized agents, each focused on a specific area:
- Code planning and architecture — helps structure your project before writing code
- Test-Driven Development — guides test-oriented development
- Vulnerability analysis — identifies security issues in code
- Language-specific reviewers — dedicated reviewers for Python, Go, C++, Rust, Kotlin, Java, and TypeScript
- Build error resolution — diagnoses and fixes compilation failures
- E2E test coordination — orchestrates end-to-end tests with Playwright
- Documentation updates — keeps documentation in sync with code
Comprehensive Skills
Over 125 skills covering:
- Backend and frontend patterns
- Language-specific best practices
- Security and testing workflows
- Database migrations
- API design
- Deployment strategies
- Content creation (articles, slides, market research)
Persistent Memory
One of the most useful features: ECC maintains memory across sessions. This means your work context is not lost when you restart Claude Code. It uses automated hooks that save and load context automatically.
Token Optimization
The plugin implements smart optimization mechanisms:
- Model selection tailored to each task
- System prompt slimming to reduce consumption
- Background process management
- Parallelization with git worktrees
Supported Languages and Technologies
ECC supports a broad ecosystem:
- Languages: TypeScript, Python, Go, Java, Kotlin, C++, Rust, Perl, PHP, Swift
- Frameworks: Django, Laravel, Spring Boot, React, Next.js, Axum
- Databases: PostgreSQL, Supabase, ClickHouse
- Testing: Playwright E2E, pytest, GoogleTest
- Tools: Docker, PM2, Git, CI/CD systems
How to Install
Prerequisite: Claude Code
First, you need to have Claude Code installed:
npm install -g @anthropic-ai/claude-code
Via Plugin Marketplace (recommended)
# Add from marketplace
/plugin marketplace add affaan-m/everything-claude-code
# Install
/plugin install everything-claude-code@everything-claude-code
Manual Installation
# Clone the repository
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code
npm install
# View available options
./install.sh --help
The --help flag shows all available languages and installation options:
# Available languages: cpp, csharp, go, java, javascript, kotlin, perl, php, python, rust, swift, typescript
# Install for one or more languages
./install.sh typescript
./install.sh python golang rust
# The default target is claude (~/.claude/rules/), but it can be changed
./install.sh --target cursor typescript # Installs to ./.cursor/
./install.sh --target antigravity python # Installs to ./.agent/
# Simulate the installation without copying files
./install.sh --dry-run typescript
It also supports installation via npx ecc-install for convenience on any platform.
ECC vs Individual Plugins
Claude Code has a native plugin system where each plugin is focused and specific — an LSP for TypeScript, another for Python, a Sentry integration, etc. Each one adds a specific capability and is lightweight by nature.
ECC takes a completely different approach. It is a complete framework that delivers the entire development ecosystem at once:
| Individual Plugins | ECC | |
|---|---|---|
| Scope | A specific feature | Complete framework |
| Size | Lightweight, modular | Large, comprehensive |
| Approach | Does one thing well | Covers the entire development cycle |
| Opinionated | Neutral | Opinionated (defines workflows like TDD, code review, security scan) |
| Installation | /plugin install name | install.sh with language selection |
In practice, the two complement each other. You can use ECC as a foundation and add individual plugins for specific tools it doesn't cover.
Why Use It?
If you already work with Claude Code, ECC is almost a must-have. It transforms an already powerful tool into something even more productive:
- Less repetition — specialized agents already know the best practices for your language
- More consistency — standardized skills ensure uniform quality
- Real memory — no need to re-explain context every session
- Built-in security — vulnerability analysis as part of the workflow
- Multi-language — a single framework for all your projects
Conclusion
Everything Claude Code is one of those open-source projects that deserves attention. With over 100K stars, an active community, and features that truly make a difference in daily work, it's worth trying.
The project is MIT licensed and available on GitHub.
