Decision brief

ECC is a performance optimization system for AI agents built to enhance skills, instincts, memory, security, and development processes.

Good fit when

  • When you are specifically working with AI agents like Claude Code and Codex that require advanced performance tuning across multiple dimensions such as skills and memory management.
  • If your project benefits from a research-first approach towards enhancing the capabilities of AI agents in terms of their operational efficiency and security measures.

Avoid when

  • For projects focusing solely on traditional software development workflows without AI components, ECC's specialized tools are not necessary.
  • In scenarios where you're working with closed-source or proprietary AI systems that do not allow for the same levels of customization as open platforms like those optimized by ECC.
Hosting:
unknown - ECC requires JavaScript environment and is open-source, licensed under MIT. Specific setup details are not provided within repository data.
Pricing:
freemium - Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project.

README

Install with Claude Code

Run these commands inside Claude Code:

/plugin marketplace add https://github.com/affaan-m/ECC
/plugin install ecc@ecc

That installs ECC's skills, agents, commands, and plugin-managed hooks. If you choose this path, stop there. Do not also run a full manual install into Claude Code.

Guided package setup is coming in ecc-universal 2.2.0. Use the native Claude plugin commands above while npm remains on 2.1.0.
