Definition
What belongs in Frameworks & Standards?
This category covers reusable development abstractions and open standards in which agents, agent runtimes, or agent interactions are the central subject.
Includes implementation frameworks, SDKs, specifications, and interoperability standards that define first-class agent abstractions, runtimes, messages, interfaces, or packaging.
Scope
Inclusion and exclusion criteria
Include when
- The framework provides first-class agent abstractions, execution, tools, state, or coordination.
- The standard defines interoperable agent behavior, messages, interfaces, or packaging.
- Removing the agent concept would fundamentally change the framework or specification.
Exclude when
- It is a general AI, machine-learning, or application framework with no first-class agent model.
- It is an informal convention or thin wrapper without maintained documentation or specification.
Selection guide
How to compare these tools
- Is this an implementation framework, an SDK, or an interoperability standard?
- Which agent concepts and extension points are defined?
- What implementations, versioning, and compatibility evidence exist?
Typical use cases
- Build agents with reusable tool, state, and execution abstractions
- Connect agents and runtimes through interoperable interfaces
- Evaluate compatibility across implementations and specification versions
Category evidence
Sources for this category guidance
- Agent2Agent (A2A) Protocol specification
The A2A specification defines an open interaction model through which independent agent systems discover capabilities, exchange information, and manage collaborative tasks.
