Everything Claude Code (ECC) is an open-source operator system that extends Claude Code with 60 specialized agents, 232 composable skills, 75 slash commands, and a 1,282-test security scanner called AgentShield. It transforms ad-hoc AI prompting into a structured, auditable engineering platform with lifecycle hooks, policy rules, and multi-harness support for Codex CLI, Cursor, and OpenCode. Teams install it via npm, commit the .ecc/ directory to Git for shared standards, and integrate AgentShield scan results into CI/CD pipelines as quality gates. Custom agents, skills, and rules can be defined in YAML to address domain-specific needs like PCI-DSS or HIPAA compliance.
