Everything Claude Code (ECC)

What it is

Everything Claude Code (ECC) is an advanced, production-grade performance optimization ecosystem and suite of extensions built specifically for terminal-native AI harnesses, primarily Claude Code. Built for early January 2027 workflows, it functions as an active, integrated runtime of specialized subagents, lifecycle hooks, and contextual rules designed to maximize reasoning fidelity across frontier models (including Claude 5.6, GPT-5.6, Gemini 4.0 Ultra, DeepSeek-V4, and Qwen 3.6 VL).

What problem it solves

It bridges the critical gap between a raw AI terminal CLI and a fully functional, autonomous software engineering environment. ECC addresses agent context-window saturation, security vulnerability exposures, memory state persistence across development sessions, and domain-specific coding standard compliance. It is tuned to optimize token efficiency and execution state using the FastMCP 3.1 Task Protocol.

Where it fits in the stack

AI Assistants & Knowledge / Developer Tooling Layer. It functions as the local runtime supervisor and rule enforcement subsystem, operating directly on top of command-line agents.

Typical use cases

  • Automated Repository Linting: Triggering automated validation checks immediately following file edits to correct syntax issues.
  • Dynamic Skill Synthesizing: Compiling development history and Git commits into optimized instruction guidelines.
  • Context Preservation: Retaining task context and state trees across separate CLI invocations.
  • Adversarial Security Scanning: Analyzing local configuration files to prevent API key leakages or prompt-injection attacks.

Strengths

  • Massive Skill Library: Contains over 182+ domain-specific skills for 10+ core programming languages.
  • AgentShield Integration: Built-in v2.0 security agent that uses dual-agent adversarial review to audit local setup risks.
  • SOTA Alignment: Native support for Claude 5.6 and GPT-5.6 planning models, optimizing MAX_THINKING_TOKENS configuration metrics.
  • Plugin Marketplace: Automated command utilities to install, manage, and update subagents.

Limitations

  • Manual Installation Requirements: Certain custom system-level lifecycle hooks require physical script placement because of sandboxing.
  • Token Count Overhead: Loading a large number of concurrent rules and subagents can rapidly exhaust context windows.
  • Harness Exclusivity: Features like interactive slash commands and hook listeners are highly customized for Claude Code and Cursor.

When to use it

  • When operating terminal-native agents like Claude Code on large, multi-tier software repositories.
  • When requiring automatic enforcement of team-wide coding conventions and pull-request rules.
  • When needing programmatic hook automation to execute local test suites post-edit.

When not to use it

  • For quick, single-file scripts where vanilla CLI reasoning is sufficient.
  • If your workflow is strictly confined to graphical web-based interfaces with no local shell access.

Getting started

To set up Everything Claude Code (ECC) in your local environment, install the integration package through the marketplace:

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

# Perform the plugin installation
/plugin install everything-claude-code@everything-claude-code

Manual Installation (Subagents setup)

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

# Copy subagents into the local Claude environment
mkdir -p ~/.claude/agents/
cp agents/*.md ~/.claude/agents/

CLI examples

The ECC plugin offers command-line operations for auditing and asset management.

1. Execute Security Scan with AgentShield

# Audit local configuration files for secrets and permissions
/plugin run ecc:agentshield --path .claude/ --level "high"

2. Synthesize Skills from Commit Logs

# Extract architectural patterns from git log into skills metadata
/plugin run ecc:skill-creator --since "5 days ago" --name "python-testing"

3. List Active Subagents

# Retrieve status of all registered persona agents
/plugin run ecc:list-agents

API examples

ECC configurations and custom post-edit hooks are structured programmatically using Python and strict Pydantic v2 validation to model ECC configuration environments.

1. Validating ECC Agent Configuration (Python)

ECC configurations are verified and mapped to local development environments using strict schemas.

from pydantic import BaseModel, Field, field_validator
from typing import Dict, List, Optional

class SecurityPolicy(BaseModel):
    block_env_secrets: bool = True
    scan_exclude: List[str] = Field(default_factory=lambda: ["*.log", "node_modules/"])

class RoutingConfig(BaseModel):
    security_audit: str = "ecc:agentshield"
    lint_fix: str = "ecc:typescript-reviewer"
    architecture_review: str = "ecc:architect"

class ECCConfig(BaseModel):
    """
    Validates ECC runtime configuration under strict Pydantic v2.
    """
    routing: RoutingConfig
    security: SecurityPolicy
    max_thinking_tokens: int = Field(default=4000, gt=0, le=16000)
    mcp_version: str = Field(default="3.1")

    @field_validator("mcp_version")
    @classmethod
    def validate_mcp_version(cls, val: str) -> str:
        if val not in ["3.1", "3.0"]:
            raise ValueError("Only FastMCP versions 3.0 and 3.1 are supported.")
        return val

# Verify active configurations
sample_config = {
    "routing": {
        "security_audit": "ecc:agentshield",
        "lint_fix": "ecc:typescript-reviewer",
        "architecture_review": "ecc:architect"
    },
    "security": {
        "block_env_secrets": True,
        "scan_exclude": ["*.log", "node_modules/", "*.key"]
    },
    "max_thinking_tokens": 8000,
    "mcp_version": "3.1"
}

validated_ecc = ECCConfig.model_validate(sample_config)
print(f"ECC Configuration validated. Active MCP Standard: {validated_ecc.mcp_version}")
print(validated_ecc.model_dump_json(indent=2))

2. Custom Post-Edit Automation Hook (Node.js)

// .claude/hooks/post-edit.js
const { execSync } = require('child_process');

module.exports = async ({ file, content }) => {
  if (file.endsWith('.py')) {
    try {
      console.log(`ECC Hook: Formatting ${file} with Ruff...`);
      execSync(`ruff format ${file}`);
    } catch (error) {
      console.error(`ECC Hook Error: ${error.message}`);
    }
  }
};
