ECC is a marketplace that installs a harness-native operator plugin of agents, skills, hooks, rules, and workflows for coding agents across multiple harnesses.
About
ECC is a marketplace that installs a single harness-native operator plugin bundling agents, skills, hooks, rules, and reusable workflows for coding agents. Its docs describe a complete system covering skills, memory optimization, security scanning, and research-first development that works across Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, and GitHub Copilot. A developer registers it to bootstrap a full cross-harness agentic setup instead of assembling TDD, code-review, and security workflows by hand.
- Single plugin bundling agents, skills, hooks, rules, and workflows
- Cross-harness: Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, GitHub Copilot
- Covers TDD, code review, security, and best-practice workflows
- MIT-licensed, selective install profiles
