ECC: Performance Optimization System for AI Agent Harnesses

Repositoryaffaan-m/ECCTool

ECC (ecc.tools) is an open-source performance optimization system for agent harnesses across Claude Code, Codex, Opencode, Cursor, and beyond.

Key points

  1. Core Capabilities: Provides skills, instincts, memory, security, and research-first development workflows for AI agents.
  2. Supported Environments: Tailored for Claude Code, Codex, Opencode, Cursor, and related developer platforms.
  3. Ecosystem & Distribution: Built mainly with JavaScript, supports MCP (Model Context Protocol), and distributes via an npm package (ecc-universal) and a GitHub App.
  4. Adoption Level: Over 247,000 GitHub stars and 37,000 forks under the permissive MIT license.

Why it matters

Autonomous coding assistants require structured memory, security policies, and toolkits to operate effectively. ECC provides a shared foundation to enhance agent reliability across different platforms.

Analysis

ECC targets software developers and teams leveraging AI agent tooling in daily workflows. Judging by its massive star count, extensive multi-language documentation, and marketplace integrations, it has reached a very high level of community adoption and maturity.
