Introduction

What is OpenSage?

OpenSage (Open Self-programming Agent Generation Engine) is an AI agent framework built on top of Google ADK (Agent Development Kit). It represents a paradigm shift from "Agent Development 1.0" to "Agent Development 2.0" — transitioning from agents that execute predefined structures to agents that can dynamically build and manage their own systems at runtime.

Core Value Proposition

From "Agent Using System" to "Agent Building System"

Agent Development 1.0 (Traditional Frameworks):

  • System structure pre-defined by humans (agent topology, workflows, tool sets)
  • Agents can only choose actions within given structures
  • Extending to new tasks requires significant manual refactoring
  • Essentially human-centered agent building

Agent Development 2.0 (OpenSage):

  • Agents upgrade from "executing predefined structures" to "autonomously building and managing structures"
  • Humans provide minimal, stable system-level scaffolding
  • Everything else is generated, composed, and scheduled by AI at runtime
  • Agents can "invent new capabilities" rather than just calling existing ones

Key Features

  • AI-written tools as first-class system entities
  • Runtime sub-agent creation and dynamic agent topology
  • Memory as manageable resource (graph-structured, Neo4j-backed)
  • Session-based resource management with complete isolation
  • Multi-sandbox support (Docker, Kubernetes under development)
  • Dynamic tool loading and runtime tool generation
  • Agent ensemble for parallel exploration
  • Integration with security tools (Joern, CodeQL, GDB, Neo4j)
  • Evaluation framework for security benchmarks

Why OpenSage?

OpenSage was designed to make self-programming agent development feel more like software development. It provides:

  • Isolation: Each agent session has its own resources, preventing interference
  • Flexibility: Easy to add new tools, sandboxes, and agents
  • Evolution: Tools and agents can be created and modified at runtime
  • Integration: Seamless integration with existing security analysis tools
  • Composability: Build complex agents from simple components
  • Scalability: Kubernetes support (under development)
