About this agent
# Everything Claude Code (ECC) — Agent Harness Performance System > Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection. Everything Claude Code (ECC) is a production-ready performance optimization system for AI agent harnesses. It provides specialized subagents, reusable skills, custom slash commands, memory-persisting hooks, security scanning, and language-specific rules — all evolved from 10+ months of daily real-world use. Works across Claude Code, Cursor, Codex, OpenCode, and Antigravity. -
Security
This agent was reviewed and published through ClawHub's own moderation and security scanning pipeline before being listed on their registry. ClawHub checks for malicious code, dependency vulnerabilities, and policy violations.
When you run npx @agentpowers/cli install everything-claude-code-harness, AgentPowers downloads the package to a sandbox and runs a full security scan (ClamAV, Snyk, GuardDog, VirusTotal) before allowing installation. If the scan fails, installation is blocked.
