Everything Claude Code

50K+ stars | 6K+ forks | 30 contributors | 5 languages supported | Anthropic Hackathon Winner

The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner.

Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products.

Works across Claude Code, Codex, Cowork, and other AI agent harnesses.

The Guides

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

Shorthand Guide Setup, foundations, philosophy. Read this first.	Longform Guide Token optimization, memory persistence, evals, parallelization.

What's New

v1.8.0 — Harness Performance System (Mar 2026)

• Harness-first release — ECC is now explicitly framed as an agent harness performance system, not just a config pack.
• Hook reliability overhaul — SessionStart root fallback, Stop-phase session summaries, and script-based hooks replacing fragile inline one-liners.
• Hook runtime controls — ECC_HOOK_PROFILE=minimal|standard|strict and ECC_DISABLED_HOOKS=... for runtime gating without editing hook files.
• New harness commands — /harness-audit, /loop-start, /loop-status, /quality-gate, /model-route.
• NanoClaw v2 — model routing, skill hot-load, session branch/search/export/compact/metrics.
• Cross-harness parity — behavior tightened across Claude Code, Cursor, OpenCode, and Codex app/CLI.
• 997 internal tests passing — full suite green after hook/runtime refactor and compatibility updates.

v1.7.0 — Cross-Platform Expansion & Presentation Builder (Feb 2026)

• Codex app + CLI support — Direct AGENTS.md-based Codex support, installer targeting, and Codex docs
• frontend-slides skill — Zero-dependency HTML presentation builder with PPTX conversion guidance and strict viewport-fit rules
• 5 new generic business/content skills — article-writing, content-engine, market-research, investor-materials, investor-outreach
• Broader tool coverage — Cursor, Codex, and OpenCode support tightened so the same repo ships cleanly across all major harnesses
• 992 internal tests — Expanded validation and regression coverage across plugin, hooks, skills, and packaging

v1.6.0 — Codex CLI, AgentShield & Marketplace (Feb 2026)

• Codex CLI support — New /codex-setup command generates codex.md for OpenAI Codex CLI compatibility
• 7 new skills — search-first, swift-actor-persistence, swift-protocol-di-testing, regex-vs-llm-structured-text, content-hash-cache-pattern, cost-aware-llm-pipeline, skill-stocktake
• AgentShield integration — /security-scan skill runs AgentShield directly from Claude Code; 1282 tests, 102 rules
• GitHub Marketplace — ECC Tools GitHub App live at github.com/marketplace/ecc-tools with free/pro/enterprise tiers
• 30+ community PRs merged — Contributions from 30 contributors across 6 languages
• 978 internal tests — Expanded validation suite across agents, skills, commands, hooks, and rules

v1.4.1 — Bug Fix (Feb 2026)

• Fixed instinct import content loss — parse_instinct_file() was silently dropping all content after frontmatter (Action, Evidence, Examples sections) during /instinct-import. Fixed by community contributor @ericcai0814 (#148, #161)

v1.4.0 — Multi-Language Rules, Installation Wizard & PM2 (Feb 2026)

• Interactive installation wizard — New configure-ecc skill provides guided setup with merge/overwrite detection
• PM2 & multi-agent orchestration — 6 new commands (/pm2, /multi-plan, /multi-execute, /multi-backend, /multi-frontend, /multi-workflow) for managing complex multi-service workflows
• Multi-language rules architecture — Rules restructured from flat files into common/ + typescript/ + python/ + golang/ directories. Install only the languages you need
• Chinese (zh-CN) translations — Complete translation of all agents, commands, skills, and rules (80+ files)
• GitHub Sponsors support — Sponsor the project via GitHub Sponsors
• Enhanced CONTRIBUTING.md — Detailed PR templates for each contribution type

v1.3.0 — OpenCode Plugin Support (Feb 2026)

• Full OpenCode integration — 12 agents, 24 commands, 16 skills with hook support via OpenCode's plugin system (20+ event types)
• 3 native custom tools — run-tests, check-coverage, security-audit
• LLM documentation — llms.txt for comprehensive OpenCode docs

v1.2.0 — Unified Commands & Skills (Feb 2026)

• Python/Django support — Django patterns, security, TDD, and verification skills
• Java Spring Boot skills — Patterns, security, TDD, and verification for Spring Boot
• Session management — /sessions command for session history

🚀 Quick Start

Get up and running in under 2 minutes:

Step 1: Install the Plugin

# Add marketplace
/plugin marketplace add affaan-m/everything-claude-code

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

Step 2: Install Rules (Required)

⚠️ Important: Claude Code plugins cannot distribute rules automatically. Install them manually:

# Clone the repo first
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# Install dependencies (pick your package manager)
npm install        # or: pnpm install | yarn install | bun install

# macOS/Linux
./install.sh typescript    # or python or golang or swift or php
# ./install.sh typescript python golang swift php
# ./install.sh --target cursor typescript
# ./install.sh --target antigravity typescript

# Windows PowerShell
.\install.ps1 typescript   # or python or golang or swift or php
# .\install.ps1 typescript python golang swift php
# .\install.ps1 --target cursor typescript
# .\install.ps1 --target antigravity typescript

# npm-installed compatibility entrypoint also works cross-platform
npx ecc-install typescript

For manual install instructions see the README in the rules/ folder.

Step 3: Start Using

# Try a command (plugin install uses namespaced form)
/everything-claude-code:plan "Add user authentication"

# Manual install (Option 2) uses the shorter form:
# /plan "Add user authentication"

# Check available commands
/plugin list everything-claude-code@everything-claude-code

✨ That's it! You now have access to 25 agents, 108 skills, and 57 commands.

🌐 Cross-Platform Support

This plugin now fully supports Windows, macOS, and Linux, alongside tight integration across major IDEs (Cursor, OpenCode, Antigravity) and CLI harnesses. 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.

Hook Runtime Controls

Use runtime flags to tune strictness or disable specific hooks temporarily:

# Hook strictness profile (default: standard)
export ECC_HOOK_PROFILE=standard

# Comma-separated hook IDs to disable
export ECC_DISABLED_HOOKS="pre:bash:tmux-reminder,post:edit:typecheck"

🛠️ Ecosystem Tools

Skill Creator

Two ways to generate Claude Code skills from your repository:

Option A: Local Analysis (Built-in)

Use the /skill-create command for local analysis without external services:

/skill-create                    # Analyze current repo
/skill-create --instincts        # Also generate instincts for continuous-learning

This analyzes your git history locally and generates SKILL.md files.

Option B: GitHub App (Advanced)

For advanced features (10k+ commits, auto-PRs, team sharing):

Install GitHub App | ecc.tools

# Comment on any issue:
/skill-creator analyze

# Or auto-triggers on push to default branch

Both options create:

• SKILL.md files - Ready-to-use skills for Claude Code
• Instinct collections - For continuous-learning-v2
• Pattern extraction - Learns from your commit history

AgentShield — Security Auditor

Built at the Claude Code Hackathon (Cerebral Valley x Anthropic, Feb 2026). 1282 tests, 98% coverage, 102 static analysis rules.

Scan your Claude Code configuration for vulnerabilities, misconfigurations, and injection risks.

# Quick scan (no install needed)
npx ecc-agentshield scan

# Auto-fix safe issues
npx ecc-agentshield scan --fix

# Deep analysis with three Opus 4.6 agents
npx ecc-agentshield scan --opus --stream

# Generate secure config from scratch
npx ecc-agentshield init

What it scans: CLAUDE.md, settings.json, MCP configs, hooks, agent definitions, and skills across 5 categories — secrets detection (14 patterns), permission auditing, hook injection analysis, MCP server risk profiling, and agent config review.

The --opus flag runs three Claude Opus 4.6 agents in a red-team/blue-team/auditor pipeline. The attacker finds exploit chains, the defender evaluates protections, and the auditor synthesizes both into a prioritized risk assessment. Adversarial reasoning, not just pattern matching.

Output formats: Terminal (color-graded A-F), JSON (CI pipelines), Markdown, HTML. Exit code 2 on critical findings for build gates.

Use /security-scan in Claude Code to run it, or add to CI with the GitHub Action.

🔬 Plankton — Write-Time Code Quality Enforcement

Plankton (credit: @alxfazio) is a recommended companion for write-time code quality enforcement. It runs formatters and 20+ linters on every file edit via PostToolUse hooks, then spawns Claude subprocesses (routed to Haiku/Sonnet/Opus by violation complexity) to fix issues the main agent missed. Three-phase architecture: auto-format silently (40-50% of issues), collect remaining violations as structured JSON, delegate fixes to a subprocess. Includes config protection hooks that prevent agents from modifying linter configs to pass instead of fixing code. Supports Python, TypeScript, Shell, YAML, JSON, TOML, Markdown, and Dockerfile. Use alongside AgentShield for security + quality coverage. See skills/plankton-code-quality/ for full integration guide.

🧠 Continuous Learning v2

The instinct-based learning system automatically learns your patterns:

/instinct-status        # Show learned instincts with confidence
/instinct-import <file> # Import instincts from others
/instinct-export        # Export your instincts for sharing
/evolve                 # Cluster related instincts into skills

See skills/continuous-learning-v2/ for full documentation.

📋 Requirements

Claude Code CLI Version

Minimum version: v2.1.0 or later

This plugin requires Claude Code CLI v2.1.0+ due to changes in how the plugin system handles hooks.

Check your version:

claude --version

Important: Hooks Auto-Loading Behavior

⚠️ For Contributors: Do NOT add a "hooks" field to .claude-plugin/plugin.json. This is enforced by a regression test.

Claude Code v2.1+ automatically loads hooks/hooks.json from any installed plugin by convention. Explicitly declaring it in plugin.json causes a duplicate detection error:

Duplicate hooks file detected: ./hooks/hooks.json resolves to already-loaded file

History: This has caused repeated fix/revert cycles in this repo (#29, #52, #103). The behavior changed between Claude Code versions, leading to confusion. We now have a regression test to prevent this from being reintroduced.

        "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.

Note: The Claude Code plugin system does not support distributing rules via plugins (upstream limitation). You need to install rules manually:

# Clone the repo first
git clone https://github.com/affaan-m/everything-claude-code.git

# Option A: User-level rules (applies to all projects)
mkdir -p ~/.claude/rules
cp -r everything-claude-code/rules/common/* ~/.claude/rules/
cp -r everything-claude-code/rules/typescript/* ~/.claude/rules/   # pick your stack
cp -r everything-claude-code/rules/python/* ~/.claude/rules/
cp -r everything-claude-code/rules/golang/* ~/.claude/rules/
cp -r everything-claude-code/rules/php/* ~/.claude/rules/

# Option B: Project-level rules (applies to current project only)
mkdir -p .claude/rules
cp -r everything-claude-code/rules/common/* .claude/rules/
cp -r everything-claude-code/rules/typescript/* .claude/rules/     # pick your stack

🔧 Option 2: Manual Installation

If you prefer manual control over what's installed:

# Clone the repo
git clone https://github.com/affaan-m/everything-claude-code.git

# Copy agents to your Claude config
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Copy rules (common + language-specific)
cp -r everything-claude-code/rules/common/* ~/.claude/rules/
cp -r everything-claude-code/rules/typescript/* ~/.claude/rules/   # pick your stack
cp -r everything-claude-code/rules/python/* ~/.claude/rules/
cp -r everything-claude-code/rules/golang/* ~/.claude/rules/
cp -r everything-claude-code/rules/php/* ~/.claude/rules/

# Copy commands
cp everything-claude-code/commands/*.md ~/.claude/commands/

# Copy skills (core vs niche)
# Recommended (new users): core/general skills only
cp -r everything-claude-code/.agents/skills/* ~/.claude/skills/
cp -r everything-claude-code/skills/search-first ~/.claude/skills/

# Optional: add niche/framework-specific skills only when needed
# for s in django-patterns django-tdd laravel-patterns springboot-patterns; do
#   cp -r everything-claude-code/skills/$s ~/.claude/skills/
# done

Add hooks to settings.json

Copy the hooks from hooks/hooks.json to your ~/.claude/settings.json.

Configure MCPs

Copy desired MCP servers from mcp-configs/mcp-servers.json to your ~/.claude.json.

Important: Replace YOUR_*_HERE placeholders with your actual API keys.

🎯 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 matches \"\\\\.(ts|tsx|js|jsx)$\"",
  "hooks": [{
    "type": "command",
    "command": "#!/bin/bash\ngrep -n 'console\\.log' \"$file_path\" && echo '[Hook] Remove console.log' >&2"
  }]
}

Rules

Rules are always-follow guidelines, organized into common/ (language-agnostic) + language-specific directories:

rules/
  common/          # Universal principles (always install)
  typescript/      # TS/JS specific patterns and tools
  python/          # Python specific patterns and tools
  golang/          # Go specific patterns and tools
  swift/           # Swift specific patterns and tools
  php/             # PHP specific patterns and tools

See rules/README.md for installation and structure details.

Common Workflows

Starting a new feature:

/everything-claude-code:plan "Add user authentication with OAuth"
                                              → planner creates implementation blueprint
/tdd                                          → tdd-guide enforces write-tests-first
/code-review                                  → code-reviewer checks your work

Fixing a bug:

/tdd                                          → tdd-guide: write a failing test that reproduces it
                                              → implement the fix, verify test passes
/code-review                                  → code-reviewer: catch regressions

Preparing for production:

/security-scan                                → security-reviewer: OWASP Top 10 audit
/e2e                                          → e2e-runner: critical user flow tests
/test-coverage                                → verify 80%+ coverage

Cursor IDE Support

ECC provides full Cursor IDE support with hooks, rules, agents, skills, commands, and MCP configs adapted for Cursor's native format.

Quick Start (Cursor)

# macOS/Linux
./install.sh --target cursor typescript
./install.sh --target cursor python golang swift php

# Windows PowerShell
.\install.ps1 --target cursor typescript
.\install.ps1 --target cursor python golang swift php

What's Included

Hook Architecture (DRY Adapter Pattern)

Cursor has more hook events than Claude Code (20 vs 8). The .cursor/hooks/adapter.js module transforms Cursor's stdin JSON to Claude Code's format, allowing existing scripts/hooks/*.js to be reused without duplication.

Cursor stdin JSON → adapter.js → transforms → scripts/hooks/*.js
                                              (shared with Claude Code)

Key hooks:

• beforeShellExecution — Blocks dev servers outside tmux (exit 2), git push review
• afterFileEdit — Auto-format + TypeScript check + console.log warning
• beforeSubmitPrompt — Detects secrets (sk-, ghp_, AKIA patterns) in prompts
• beforeTabFileRead — Blocks Tab from reading .env, .key, .pem files (exit 2)
• beforeMCPExecution / afterMCPExecution — MCP audit logging

Rules Format

Cursor rules use YAML frontmatter with description, globs, and alwaysApply:

---
description: "TypeScript coding style extending common rules"
globs: ["**/*.ts", "**/*.tsx", "**/*.js", "**/*.jsx"]
alwaysApply: false
---

Codex macOS App + CLI Support

ECC provides first-class Codex support for both the macOS app and CLI, with a reference configuration, Codex-specific AGENTS.md supplement, and shared skills.

Quick Start (Codex App + CLI)

# Run Codex CLI in the repo — AGENTS.md and .codex/ are auto-detected
codex

# Optional: copy the global-safe defaults to your home directory
cp .codex/config.toml ~/.codex/config.toml

Codex macOS app:

• Open this repository as your workspace.
• The root AGENTS.md is auto-detected.
• .codex/config.toml and .codex/agents/*.toml work best when kept project-local.
• The reference .codex/config.toml intentionally does not pin model or model_provider, so Codex uses its own current default unless you override it.
• Optional: copy .codex/config.toml to ~/.codex/config.toml for global defaults; keep the multi-agent role files project-local unless you also copy .codex/agents/.

What's Included

Skills

Skills at .agents/skills/ are auto-loaded by Codex:

Key Limitation

Codex does not yet provide Claude-style hook execution parity. ECC enforcement there is instruction-based via AGENTS.md, optional model_instructions_file overrides, and sandbox/approval settings.

Multi-Agent Support

Current Codex builds support experimental multi-agent workflows.

• Enable features.multi_agent = true in .codex/config.toml
• Define roles under [agents.<name>]
• Point each role at a file under .codex/agents/
• Use /agent in the CLI to inspect or steer child agents

ECC ships three sample role configs:

🔌 OpenCode Support

ECC provides full OpenCode support including plugins and hooks.

Quick Start

# Install OpenCode
npm install -g opencode

# Run in the repository root
opencode

The configuration is automatically detected from .opencode/opencode.json.

Feature Parity

Hook Support via Plugins

OpenCode's plugin system is MORE sophisticated than Claude Code with 20+ event types:

Additional OpenCode events: file.edited, file.watcher.updated, message.updated, lsp.client.diagnostics, tui.toast.show, and more.

Available Commands (31+)

Plugin Installation

Option 1: Use directly

cd everything-claude-code
opencode

Option 2: Install as npm package

npm install ecc-universal

Then add to your opencode.json:

{
  "plugin": ["ecc-universal"]
}

That npm plugin entry enables ECC's published OpenCode plugin module (hooks/events and plugin tools). It does not automatically add ECC's full command/agent/instruction catalog to your project config.

For the full ECC OpenCode setup, either:

• run OpenCode inside this repository, or
• copy the bundled .opencode/ config assets into your project and wire the instructions, agent, and command entries in opencode.json

Documentation

• Migration Guide: .opencode/MIGRATION.md
• OpenCode Plugin README: .opencode/README.md
• Consolidated Rules: .opencode/instructions/INSTRUCTIONS.md
• LLM Documentation: llms.txt (complete OpenCode docs for LLMs)

Cross-Tool Feature Parity

ECC is the first plugin to maximize every major AI coding tool. Here's how each harness compares:

Key architectural decisions:

• AGENTS.md at root is the universal cross-tool file (read by all 4 tools)
• DRY adapter pattern lets Cursor reuse Claude Code's hook scripts without duplication
• Skills format (SKILL.md with YAML frontmatter) works across Claude Code, Codex, and OpenCode
• Codex's lack of hooks is compensated by AGENTS.md, optional model_instructions_file overrides, and sandbox permissions

📖 Background

I've been using Claude Code since the experimental rollout. Won the Anthropic x Forum Ventures hackathon in Sep 2025 building zenith.chat with @DRodriguezFX - entirely using Claude Code.

These configs are battle-tested across multiple production applications.

Token Optimization

Claude Code usage can be expensive if you don't manage token consumption. These settings significantly reduce costs without sacrificing quality.

Recommended Settings

Add to ~/.claude/settings.json:

{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50"
  }
}

Switch to Opus only when you need deep architectural reasoning:

/model opus

Daily Workflow Commands

Strategic Compaction

The strategic-compact skill (included in this plugin) suggests /compact at logical breakpoints instead of relying on auto-compaction at 95% context. See skills/strategic-compact/SKILL.md for the full decision guide.

When to compact:

• After research/exploration, before implementation
• After completing a milestone, before starting the next
• After debugging, before continuing feature work
• After a failed approach, before trying a new one

When NOT to compact:

• Mid-implementation (you'll lose variable names, file paths, partial state)

Context Window Management

Critical: Don't enable all MCPs at once. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k.

• Keep under 10 MCPs enabled per project
• Keep under 80 tools active
• Use disabledMcpServers in project config to disable unused ones

Agent Teams Cost Warning

Agent Teams spawns multiple context windows. Each teammate consumes tokens independently. Only use for tasks where parallelism provides clear value (multi-module work, parallel reviews). For simple sequential tasks, subagents are more token-efficient.

⚠️ Important Notes

Token Optimization

Hitting daily limits? See the Token Optimization Guide for recommended settings and workflow tips.

Quick wins:

// ~/.claude/settings.json
{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50",
    "CLAUDE_CODE_SUBAGENT_MODEL": "haiku"
  }
}

Use /clear between unrelated tasks, /compact at logical breakpoints, and /cost to monitor spending.

Customization

These configs work for my workflow. You should:

1. Start with what resonates
2. Modify for your stack
3. Remove what you don't use
4. Add your own patterns
