The harness-native operator system for agentic work. Built from real-world multi-harness engineering workflows.

Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, skills, hooks, rules, MCP configurations, and legacy command shims evolved over 10+ months of intensive daily use building real products.

Works across Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, GitHub Copilot, and other AI agent harnesses.

ECC v2.0.0 adds the public Hermes operator story on top of that reusable layer: start with the Hermes setup guide, then review the 2.0.0 release notes and cross-harness architecture.
