A plugin package that equips coding agents with a complete engineering workflow: planning, testing, implementation, review, verification, memory, and improvement, accompanied by numerous sub-agents, skills, hooks, and configuration security scans.

Rationale
- The author states it includes 71 agents, 311 skills, and 97 legacy command entry points, plus hooks, rules, memory, continuous learning, and AgentShield security scanning
- The 2.2 version offers guided installation for Claude Code, Codex, and Kimi Code, with pre-checks before writing, a final confirmation step, and a --dry-run option to preview without writing
- Limited-capability adaptations are provided for Cursor, OpenCode, Gemini, Zed, Copilot, Qwen, and others; the author advises checking the support matrix first and not assuming feature parity across platforms
Usage
- npx [email protected] setup (requires Node.js 18+, Git, and Claude Code 2.1+); for personal use, select Global user and Standard hooks
- To configure multiple agents together: npx [email protected] install --guided; after installation, verify that ecc@ecc is enabled in Claude Code using /plugin list
Risks
- The author warns to obtain the software only from the official repository, the npm packages ecc-universal / ecc-agentshield, and ecc.tools, as third-party redistributions may contain malicious code
- Do not stack multiple installation methods within the same agent, as this will duplicate skills and hooks; hooks run automatically during sessions
- The open-source portion is MIT licensed, while the GitHub App (ECC Pro) for private repositories is paid
