Ecc.tools

What is Ecc.tools?

Ecc.tools is the open agent harness system behind a 210K+ stars OSS ecosystem, designed to automate and secure GitHub App workflows. It provides a local-first control plane for observability, orchestration, session management, and cross-harness operations, sitting above individual tools like Claude Code, Codex, Cursor, and OpenCode. The system allows teams to pick a profile (core, developer, security, or full) and install skills and agents tailored to their needs. AgentShield scans every session for protection, while the GitHub App converts repository history into reusable defaults, enabling repo-native guidance. This setup is ideal for OSS maintainers evaluating on public repos, teams needing private repo coverage with active-seat billing, and organizations requiring procurement, governance, and rollout support.

Key features include a flexible install builder, AgentShield for session protection, and the ability to audit configs locally before adding automation, policy packs, and enterprise reporting. The GitHub App serves as the fastest path from the OSS ecosystem into a repo-native workflow, starting free on public repos and scaling to Pro for private repositories and active seats, then Enterprise when coordination and governance become critical. ECC 2.0 is shipped as a local-first control plane that upgrades the same workflow without forcing a tool reset or hiding the open-source layer.

Benefits include reduced coordination burden, enhanced security through session scanning, and seamless integration with existing tools. Use cases range from individual developers automating code reviews to large enterprises managing rollout and policy compliance. Technical details highlight that the repo drives distribution, AgentShield provides protection, and ECC 2.0 operates as the operator layer above individual harnesses. Skills, commands, hooks, adapters, demos, and install profiles keep the system useful before any payment, with protection living beside distribution. Teams can start with the GitHub App for repo-native guidance and add layers like AgentShield and rollout as needs grow.
