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.

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

What's New

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

🚀 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

# Recommended: use the installer (handles common + language rules safely)
./install.sh typescript    # or python or golang
# You can pass multiple languages:
# ./install.sh typescript python golang
# or target cursor:
# ./install.sh --target cursor typescript

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

Step 3: Start Using

# Try a command
/plan "Add user authentication"

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

✨ That's it! You now have access to 13 agents, 37 skills, and 31 commands.

🌐 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.

🛠️ 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). 876 tests, 98% coverage, 96 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.

GitHub | npm

🧠 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.

📥 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.

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)
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/

# 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/

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

# Copy skills
cp -r everything-claude-code/skills/* ~/.claude/skills/

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

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

🗺️ Which Agent Should I Use?

Not sure where to start? Use this quick reference:

I want to...	Use this command	Agent used
Plan a new feature	/plan "Add auth"	planner
Design system architecture	/plan + architect agent	architect
Write code with tests first	/tdd	tdd-guide
Review code I just wrote	/code-review	code-reviewer
Fix a failing build	/build-fix	build-error-resolver
Run end-to-end tests	/e2e	e2e-runner
Find security vulnerabilities	/security-scan	security-reviewer
Remove dead code	/refactor-clean	refactor-cleaner
Update documentation	/update-docs	doc-updater
Review Go code	/go-review	go-reviewer
Review Python code	/python-review	python-reviewer
Audit database queries	(auto-delegated)	database-reviewer

Common Workflows

Starting a new feature:

/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

❓ FAQ

How do I check which agents/commands are installed?

/plugin list everything-claude-code@everything-claude-code

This shows all available agents, commands, and skills from the plugin.

My hooks aren't working / I see "Duplicate hooks file" errors

This is the most common issue. Do NOT add a "hooks" field to .claude-plugin/plugin.json. Claude Code v2.1+ automatically loads hooks/hooks.json from installed plugins. Explicitly declaring it causes duplicate detection errors. See #29, #52, #103.

My context window is shrinking / Claude is running out of context

Too many MCP servers eat your context. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k.

Fix: Disable unused MCPs per project:

// In your project's .claude/settings.json
{
  "disabledMcpServers": ["supabase", "railway", "vercel"]
}

Keep under 10 MCPs enabled and under 80 tools active.

Can I use only some components (e.g., just agents)?

Yes. Use Option 2 (manual installation) and copy only what you need:

# Just agents
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Just rules
cp -r everything-claude-code/rules/common/* ~/.claude/rules/

Each component is fully independent.

Does this work with Cursor / OpenCode?

Yes. ECC is cross-platform:

• Cursor: Pre-translated configs in .cursor/. See Cursor IDE Support.
• OpenCode: Full plugin support in .opencode/. See OpenCode Support.
• Claude Code: Native — this is the primary target.

How do I contribute a new skill or agent?

See CONTRIBUTING.md. The short version:

1. Fork the repo
2. Create your skill in skills/your-skill-name/SKILL.md (with YAML frontmatter)
3. Or create an agent in agents/your-agent.md
4. Submit a PR with a clear description of what it does and when to use it

📖 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"
  }
}

Setting	Default	Recommended	Impact
model	opus	sonnet	~60% cost reduction; handles 80%+ of coding tasks
MAX_THINKING_TOKENS	31,999	10,000	~70% reduction in hidden thinking cost per request
CLAUDE_AUTOCOMPACT_PCT_OVERRIDE	95	50	Compacts earlier — better quality in long sessions

Switch to Opus only when you need deep architectural reasoning:

/model opus

Daily Workflow Commands

Command	When to Use
/model sonnet	Default for most tasks
/model opus	Complex architecture, debugging, deep reasoning
/clear	Between unrelated tasks (free, instant reset)
/compact	At logical task breakpoints (research done, milestone complete)
/cost	Monitor token spending during session

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
