ECC is the harness-native agent operating system for AI-assisted development. It installs directly into your AI coding assistant — Claude Code, Codex, Cursor, Gemini CLI, OpenCode, or Zed — and unlocks a complete workflow stack: reusable skills, event-driven hooks, slash commands, specialized agents, and multi-agent orchestration. Start with a minimal two-command install and grow into production-grade operator workflows.

Quickstart

Install ECC in two commands and run your first skill in under five minutes.

Installation

Full install options: profiles, targets, selective modules, and Windows/macOS/Linux instructions.

Skills

260+ reusable workflow bundles covering every major language and framework.

Hooks

Event-driven automations that fire on tool calls, session lifecycle, and quality gates.

​
What ECC Gives You

ECC turns any supported AI harness into a disciplined engineering environment with five core primitives:

Skills

Scoped workflow bundles with reusable prompts, codemaps, and supporting files for every tech stack.

Hooks

Lifecycle automations for PreToolUse, PostToolUse, Stop, SessionStart, and PreCompact events.

Commands

93 slash-command shims for code review, orchestration, session management, and more.

Agents

66 specialized sub-agents — reviewers, build resolvers, security auditors, and planners.

Memory

SQLite-backed state store with session persistence, skill run history, and decision tracking.

Orchestration

Worktree lifecycle management, tmux integration, and PM2 multi-agent coordination.

Get Started in Minutes

1

Install ECC

Run the installer with your chosen profile and target harness:
npx ecc install --profile minimal --target claude
2

Consult the advisor

Not sure which components you need? Ask ECC to recommend them:
npx ecc consult "security reviews and TypeScript projects" --target claude
3

Browse your skills

List what’s installed and verify your setup:
npx ecc list-installed
npx ecc status
4

Start building

Open your AI harness and invoke a skill or slash command — for example /tdd-workflow in Claude Code — and let ECC guide the session.

​
