Description

The agent harness performance optimization system with skills, instincts, memory, security and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.

Key Features

  • Cross-harness compatibility - Works with Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, GitHub Copilot, and more
  • Skills and instincts system - 63 agents, 251 skills, and 79 legacy command shims as reusable behavior modules
  • Memory persistence - Hooks automatically save and load context across sessions for continuous memory
  • Security scanning - Built-in AgentShield module with attack vector detection, sandboxing, and input sanitization
  • Continuous learning - Auto-extracts patterns from sessions into reusable skills; agent improves over time
  • Token optimization - Model selection strategies, system prompt slimming, and background process management

Use Cases

💡 Add memory persistence to Claude Code or Codex so the agent retains project context across sessions
💡 Use security scanning to automatically detect vulnerabilities and dangerous operations during coding
💡 Accumulate best practices from daily development via continuous learning for a team-specific knowledge base
💡 Share unified skill configurations across multiple AI coding tools for consistent workflows

Strengths & Limitations

✅ Strengths

  • • Actively maintained, recent updates
  • • High community interest (246.4k stars)
  • • Permissive open-source license (MIT)
  • • Responsive to issues, low backlog
