Agencr.A2A is a .NET library that defines extensions for the A2A Protocol.
Represents an extension used to declare the contract of an agent, defining the intents it produces and consumes as well as any requirements necessary to fulfill its role within an A2A ecosystem.
- The intents it produces and consumes.
- The requirements it depends on (such as integrations, capabilities, or external systems).
- The configuration schema that defines how the agent is parameterized.
This extension provides a formal structure for describing how an agent behaves and interacts within an A2A ecosystem.
| Concept | Description |
|---|---|
| Intents | Declarative definitions of the events, messages, or capabilities the agent produces or consumes. |
| Requirements | Describes dependencies such as integrations or resources required for the agent to operate. |
| Configuration | Schema-based parameters used to define the agent’s runtime behavior. |
The V1AgentEcosystemExtension type aligns with the A2A Protocol AgentExtension Object.
This object standardizes how extensions are versioned and identified within A2A, defining metadata and properties that describe an agent’s structure, purpose, and relationship to other components in the A2A ecosystem.
By implementing this specification, the library provides a consistent and interoperable representation for agent contracts that can be exchanged, validated, and registered within any system that supports the A2A Protocol.
Install the library via the .NET CLI:
dotnet add package A2A.AgentEcosystemExtensionor include it in your project file:
<PackageReference Include="A2A.AgentEcosystemExtension" Version="1.0.0" />For vulnerability reporting and security guidance, see the SECURITY.md file.
