ECC (Everything Claude Code)
Agent harness performance optimization system providing 280+ cross-platform AI skills, instincts, session memory persistence, hooks runtime, and AgentShield security scanning across Claude Code, Codex, Antigravity, Cursor, and beyond.
Problem
AI coding assistants frequently lose session context, lack domain-specific engineering discipline (TDD, safe refactoring, strict security), and are locked into platform-specific configurations without cross-harness portability.
Solution
Provides a unified ecosystem of 280+ modular skills, continuous learning memory persistence, proactive context budget management, and AgentShield security auditing that work natively across all major agentic AI coding environments.
Challenge
Harmonizing tool definitions, context compaction algorithms, and permission models across disparate AI CLI agents (Claude Code vs OpenAI Codex vs Antigravity vs Cursor).
Key Features
- 280+ battle-tested AI skills across architecture, testing, security, and DevOps
- AgentShield: proactive scanning for prompt injection, leaked secrets, and malicious hooks
- Unified memory & continuous learning system that accumulates codebase instincts over sessions
- Context budget optimizer to prevent token degradation and context loss in long tasks
- Cross-platform adapters for Claude Code, Codex, Antigravity, Cursor, and Zed
