ECC ships 71 agents and 311 skills as an 'operating system' for coding agents
ECC, the agent-harness system from developer affaan-m, bundles 71 specialized agents and 311 skills into a single package for coding agents. The pitch is that instead of rebuilding a disciplined workflow in every prompt, you install it once: agents plan before they build, enforce test-driven development, review their own work, remember what worked, and scan prompts and hooks with an included AgentShield security tool. It runs best with Claude Code but has adapters for Codex, Cursor, OpenCode, Gemini and others. Installation is one command, npx ecc-universal setup, with a guided wizard. The repository has crossed 280,000 GitHub stars, making it one of the most-starred agent projects around, though it is largely the work of a single maintainer shipping weekly. The open-source repo is MIT-licensed and stays free; a paid GitHub App called ECC Pro covers private repositories.
