Overview
ECC installs a set of 68 agents, 293 skills, 94 legacy command shims, hooks, rules, memory and continuous-learning tooling into coding agents, aiming to enforce a plan, test, implement, review, verify loop. It ships as a Claude Code plugin (`ecc@ecc`) and the `ecc-universal` npm package, with guided setup for Claude Code, Codex and Kimi Code. It also bundles AgentShield, which scans prompts, hooks, MCP config, permissions and secrets.
Who it is for: Developers using Claude Code or Codex who want preset workflows
Strengths
- Guided installer with dry-run for Claude Code, Codex and Kimi Code
- Bundles AgentShield scanner for hooks, MCP config, permissions and secrets
- Large catalog: 68 agents, 293 skills, plus selectable rule packs by language
- MIT license; release 2026-10-01 and commit 2026-10-02 are recent
Weaknesses
- Full support is Claude Code only; other harnesses are capability-limited adapters
- Stacking install methods duplicates skills and hooks; reset steps are needed
- Claude plugins cannot ship rules, so those are copied manually
- ECC Pro GitHub App for private repos is paid, from $19/seat/month
What it needs
- no GPU
- Docker + Compose
- Needs Node.js 18+, Git, Claude Code 2.1+ (for plugin setup)
