Overview

Everything Claude Code (ECC) is a complete, production-hardened Claude Code plugin delivering 13 specialized sub-agents, 48+ skills, 31+ slash commands, a trigger-based hooks pipeline, multi-language rules, and MCP server configurations assembled over 10+ months of daily use. Originating as an Anthropic hackathon winner (Cerebral Valley x Anthropic, Feb 2026), it has reached 52K+ GitHub stars and 6.4K+ forks, making it the largest community-maintained Claude Code configuration library by engagement. As of v1.6.0 it supports four AI coding tools in a single installation: Claude Code, Cursor, OpenCode, and OpenAI Codex CLI.

Key Statistics

Key Features

Agents (13 Specialized Sub-Agents)

Each agent is a Markdown file with YAML frontmatter declaring name, description, tools, and model. Claude Code delegates to these agents via the Task tool.

• planner.md — Feature implementation planning; decomposes tasks into ordered steps
• architect.md — System design decisions; evaluates trade-offs across architecture options
• tdd-guide.md — Test-driven development enforcement; RED → GREEN → REFACTOR protocol
• code-reviewer.md — Quality and security review with specific checklist categories
• security-reviewer.md — Vulnerability analysis; OWASP categories, secret scanning, injection risks
• build-error-resolver.md — Root cause analysis and fix generation for build failures
• e2e-runner.md — Playwright E2E test generation and execution coordination
• refactor-cleaner.md — Dead code removal and structural cleanup
• doc-updater.md — Documentation synchronization with code changes
• go-reviewer.md / go-build-resolver.md — Go-specific code review and build error resolution
• python-reviewer.md — Python-specific code review (added v1.4.0+)
• database-reviewer.md — Database/Supabase pattern review (added v1.4.0+)

Skills (48+ Workflow Definitions)

Skills provide domain knowledge and workflow definitions. Coverage spans:

• Language standards: coding-standards, cpp-coding-standards, java-coding-standards, golang-patterns, python-patterns
• Framework patterns: frontend-patterns (React, Next.js), backend-patterns, django-patterns, springboot-patterns
• Testing: tdd-workflow, cpp-testing, django-tdd, golang-testing, python-testing, springboot-tdd, e2e-testing
• Security: security-review, django-security, springboot-security, security-scan (AgentShield integration)
• Databases: clickhouse-io, postgres-patterns, database-migrations, jpa-patterns
• Infrastructure: deployment-patterns, docker-patterns, api-design
• LLM/AI cost: cost-aware-llm-pipeline, regex-vs-llm-structured-text
• Mobile/Apple: swift-actor-persistence, swift-protocol-di-testing, liquid-glass-design, foundation-models-on-device, swift-concurrency-6-2
• Session learning: continuous-learning, continuous-learning-v2, iterative-retrieval, strategic-compact, eval-harness, verification-loop
• Meta/tooling: skill-stocktake, search-first, configure-ecc, project-guidelines-example

Commands (31+ Slash Commands)

Hooks Pipeline

Multi-Language Rules Architecture

Rules are split into four directories, allowing selective installation:

Install via ./install.sh typescript python golang (the installer script handles merge/overwrite detection).

Continuous Learning v2 (Instinct System)

The instinct system automatically extracts patterns from sessions:

• Instincts stored with confidence scores, evidence, and example sessions
• /instinct-status surfaces high-confidence patterns for review
• /evolve clusters related instincts into generalized skills via LLM analysis
• Import/export enables team-wide pattern sharing
• continuous-learning-v2/ skill documents the full lifecycle

AgentShield Security Auditor

Built at the Claude Code Hackathon (Cerebral Valley x Anthropic, Feb 2026). Scans Claude Code configuration for vulnerabilities.

npx ecc-agentshield scan         # Quick scan
npx ecc-agentshield scan --fix   # Auto-fix safe issues
npx ecc-agentshield scan --opus  # Deep analysis with three Opus 4.6 agents

Scans: CLAUDE.md, settings.json, MCP configs, hooks, agents, skills across 5 categories — secrets detection (14 patterns), permission auditing, hook injection analysis, MCP server risk profiling, and agent config review. Output formats: terminal (A-F grade), JSON, Markdown, HTML. Exit code 2 on critical findings for CI build gates.

Cross-Platform Support

All hooks and scripts rewritten in Node.js. Supports Windows, macOS, Linux. Package manager detection priority: CLAUDE_PACKAGE_MANAGER env → .claude/package-manager.json → package.json packageManager field → lock file detection → global config → fallback to first available.

Multi-Tool Support (v1.6.0)

Single config source for four AI coding tools:

• Claude Code — native via plugin marketplace
• Cursor — /.cursor/ directory with rules and agents
• OpenCode — /.opencode/ with plugin system, 20+ hook event types, 3 native custom tools
• OpenAI Codex CLI — /.codex/ via /codex-setup command generating codex.md

GitHub Marketplace App

Available at github.com/marketplace/ecc-tools. Free/Pro/Enterprise tiers. Provides /skill-creator analyze via issue comments and auto-triggers on push to default branch. Generates SKILL.md files, instinct collections, and pattern extraction from commit history.

Technical Architecture

Installation mechanism: Claude Code v2.1+ auto-loads hooks/hooks.json from any installed plugin by convention. Explicitly declaring it in plugin.json causes a duplicate detection error — the repo enforces this via a regression test.

Plugin installation:

/plugin marketplace add affaan-m/everything-claude-code
/plugin install everything-claude-code@everything-claude-code

Or manually add to ~/.claude/settings.json under extraKnownMarketplaces and enabledPlugins.

Rules require manual copy (upstream Claude Code plugin limitation — rules cannot be distributed via plugins):

git clone https://github.com/affaan-m/everything-claude-code.git
./install.sh typescript    # or python or golang

Installation and Usage

# Option 1: Install as Claude Code plugin (recommended)
/plugin marketplace add affaan-m/everything-claude-code
/plugin install everything-claude-code@everything-claude-code

# Option 2: Manual rules installation after plugin install
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code
./install.sh typescript          # single language
./install.sh typescript python golang  # multiple languages
./install.sh --target cursor typescript  # for Cursor

# Option 3: Direct settings.json (headless/CI environments)
# Add to ~/.claude/settings.json:
# "extraKnownMarketplaces": { "everything-claude-code": { "source": { "source": "github", "repo": "affaan-m/everything-claude-code" } } }
# "enabledPlugins": { "everything-claude-code@everything-claude-code": true }

# Run tests
node tests/run-all.js

# AgentShield security scan
npx ecc-agentshield scan
npx ecc-agentshield scan --fix
npx ecc-agentshield scan --opus --stream

# Configure OpenAI Codex CLI compatibility
/codex-setup

# Continuous learning workflow
/learn                   # Extract patterns from current session
/instinct-status         # View learned instincts with confidence scores
/evolve                  # Cluster instincts into skills

# Multi-agent orchestration
/multi-plan "Build user auth with OAuth and JWT"
/multi-execute

Relevance to Claude Code Development

Direct Applicability

This repository is the closest peer project to claude_skills in the Claude Code ecosystem. Both organize configuration as plugins with agents, skills, commands, hooks, and rules. Reviewing ECC's structure surfaces patterns directly applicable to claude_skills development:

• Continuous learning v2 (instinct system): Automatic session pattern extraction with confidence scoring and cluster-to-skill promotion — a novel architecture not present in claude_skills that could address the gap between ephemeral session knowledge and persistent skills.
• Language-selective rules: The common/ + per-language directory split reduces context waste for single-language projects. claude_skills uses a flat rules structure.
• Skill creator command (/skill-create): Generates SKILL.md files from git history via local analysis — a workflow that could complement claude_skills' /plugin-creator:skill-creator.
• contexts/ directory: Dynamic system prompt injection modes (dev/review/research) provide lightweight context switching without separate skills or commands.
• Real-world CLAUDE.md examples: examples/saas-nextjs-CLAUDE.md, examples/go-microservice-CLAUDE.md etc. are concrete references for users setting up their own projects.

Patterns Worth Adopting

• Blocking Stop hooks: Prevent premature session end when a multi-phase workflow is in progress — applicable to claude_skills long-running agent workflows.
• Pre/post-compact hooks: pre-compact.js + session-start restore enables seamless continuation across context resets for any skill managing multi-phase state.
• Regression test for plugin.json hooks field: Auto-detecting a common misconfiguration (duplicate hooks declaration) via a test prevents repeated fix/revert cycles.
• AgentShield scan in CI: Running npx ecc-agentshield scan as a build gate (exit code 2 on critical findings) is a concrete security enforcement pattern for Claude Code plugin repositories.

Competitive Analysis

Integration Opportunities

• The mcp-configs/mcp-servers.json pre-configured MCP definitions (GitHub, Supabase, Vercel, Railway) are directly reusable as references when documenting MCP server configurations in claude_skills.
• ECC's examples/ CLAUDE.md files for real-world stacks (SaaS Next.js, Go microservice, Django API, Rust API) are valuable research references for claude_skills documentation.
• The /security-scan skill wrapping AgentShield could be evaluated as a security audit step in claude_skills CI/pre-commit pipeline.
