Open Standard for Software Agents
Treating Agents as First-Class Citizens
Standardized metadata for production agent systems (security, governance, portability)
What is Open Standard Agents?
OSSA is an open, vendor-neutral specification for AI agents that enables interoperability across frameworks, runtimes, and organizations.
OSSA defines the contract for agent definition, deployment, and management. It does not define orchestration algorithms or runtime behavior. Just as OpenAPI describes API contracts without implementing them, OSSA provides standardized metadata for production agent systems (security, governance, portability).
Specification Standard
OSSA is NOT a framework - it's a specification that defines the contract for agent definition, deployment, and management.
Just like OpenAPI doesn't implement APIs, OSSA doesn't implement agents. It provides the standard that implementations follow.
Framework-Agnostic
Works seamlessly with any LLM framework or SDK - LangChain, Anthropic, OpenAI, CrewAI, Langflow, AutoGen, and more.
Deploy to Kubernetes, Docker, serverless, or on-premise. OSSA is infrastructure-agnostic.
Vendor-Neutral
No vendor lock-in. Write once, deploy anywhere. Move agents between teams, organizations, and infrastructures without rewriting code.
Maintained by the open source community, ensuring long-term viability and innovation.
What's New in v0.3.3
The latest OSSA release brings enterprise-grade specifications for production multi-agent systems.
Enterprise Security
- Formal security model with authentication & authorization
- Secrets management & sandboxing requirements
- FedRAMP, SOC2, HIPAA compliance profiles
Multi-Agent Orchestration
- A2A Protocol for agent-to-agent communication
- Capability URI scheme with registry format
- Instance, session, and interaction IDs
Observability
- OpenTelemetry semantic conventions
- Reasoning trace export (ReAct, CoT, ToT)
- Versioned prompt template management
Developer Experience
- Conformance testing (Basic, Standard, Enterprise)
- agents.md & llms.txt integration
- Enhanced CLI validation tools
Why Does This Matter?
Leading with portability, regulatory compliance, and vendor independence
Portability: Avoid Vendor Lock-in
Switch between AI providers (OpenAI, Anthropic, Azure) without rewriting code. Define your agent once in OSSA format, deploy anywhere. No more complete rewrites when changing frameworks.
Regulatory Compliance: Built-in Frameworks
Meet SOC2, FedRAMP, HIPAA, and GDPR requirements with standardized security models, audit trails, and data boundary controls. Compliance-ready from day one.
Vendor Independence: True Interoperability
Community-driven standard, not controlled by any single company. Works with LangChain, CrewAI, AutoGen, and any framework. Your agents, your choice.
OSSA solves this for AI agents.
One standard. Any framework. True portability. Define your agent once in OSSA format, then deploy it with LangChain, CrewAI, Anthropic, OpenAI, or any other framework. Just like OpenAPI unified REST APIs, OSSA unifies AI agents.

OSSA
LangChain / AutoGen / Semantic Kernel
Framework-specific implementations. Open source but vendor-controlled.
MCP (Model Context Protocol)
Formal standard with multi-runtime support. Focused on context, not full agent lifecycle.
