About ECC
ECC
The agent harness performance optimization system
ECC is an open-source toolkit for coding agents: a collection of skills, agents, hooks, memory and planning tools that gives agents a shared way to work across the tools you use. It installs natively as a plugin in Claude Code and Codex, through managed adapters in Cursor and OpenCode, and with project setup in Kimi Code, using a guided installer (npx ecc-universal install --guided). Alongside the MIT-licensed toolkit, the ECC GitHub App reads your repository history to prepare reviewable guidance and pull requests for your team, and AgentShield scans agent configuration for risks such as prompt injection, unsafe permissions and exposed secrets. The toolkit stays free; the GitHub App has Free, Pro and Enterprise plans.
