A unified declarative standard for AI agents, designed to bring interoperability across frameworks such as LangGraph, AutoGen, and Oracle Agent Runtime.
From fragmented agent frameworks to interoperable agentic systems
📄 Source: arXiv 2510.04173 (October 2025)
| Objective | Description |
|---|---|
| Portability & Interoperability | Move agents seamlessly between frameworks (LangGraph, AutoGen, OCI Agent Runtime). |
| Declarative Definition | Define agents in YAML/JSON instead of hardcoded logic. |
| Modularity & Composability | Reuse flows, tools, and sub-agents. |
| Explicit Control & Data Flow | Clearly define how steps connect, branch, or loop. |
| Validation & Conformance | Built-in schema validation ensures compatibility. |
| Multi-Agent Composition | Enable collaboration and orchestration among agents. |
| Concept | Explanation |
|---|---|
| Agent | The reasoning or conversational entity. |
| Flow | Structured workflow defining execution steps (nodes, branches, loops). |
| Tool | API, function, or service the agent can call. |
| Memory / Prompt Templates | Mechanisms for contextual state and conversation history. |
| Edges | Define relationships and data flow between nodes. |
These building blocks form the agent graph, which can be executed on compatible runtimes.
- Uses YAML/JSON schemas for transparent, portable definitions.
- Supports versioning, validation, and interchange.
- Reference SDK for building, validating, and exporting agents.
- Provides schema validation, object composition, and serialization.
Bridge the specification to concrete frameworks:
- OCI Agent Runtime
- LangGraph
- AutoGen
Adapters support import/export interoperability:
- Directed edges define execution order.
- Branching and loops for dynamic logic.
- Inputs/outputs explicitly mapped between steps.
- Nested flows and sub-agents enable modular reuse.
This model ensures predictability, traceability, and easy debugging across runtimes.
| Stakeholder | Benefits |
|---|---|
| Developers | Portability, validation, and reuse of components. |
| Framework Vendors | A standardized interchange format. |
| Researchers | Reproducibility and comparability across experiments. |
| Enterprises | Governance, modularity, and reduced vendor lock-in. |
In essence: “Write once, run anywhere” for AI agents.
| Challenge | Description |
|---|---|
| Early-Stage Adoption | Specification is still experimental. |
| Runtime Mismatch | Execution semantics differ between frameworks. |
| Performance Overhead | Translation layer introduces minimal latency. |
| Safety & Observability | Delegated to runtime implementations. |
Planned enhancements include:
- Memory, Planning, and Datastore extensions.
- Agent-to-Agent (A2A) communication protocols.
- SDKs for more languages (Java, TypeScript, Go).
- Conformance tests and visual editors.
- Community-driven registry of agents.
- Framework-agnostic and modular.
- Promotes ecosystem collaboration.
- Declarative, composable design.
- Slow adoption curve.
- Runtime complexity.
- Divergent adapter implementations.
- Start small and modular.
- Contribute runtime adapters early.
- Prioritize observability and safety instrumentation.
The Open Agent Specification defines a declarative, interoperable schema for building modular AI agents across multiple runtimes and ecosystems.
