Agencr A2A

Agencr.A2A is a .NET library that defines extensions for the A2A Protocol.


✨ Overview

V1AgentEcosystemExtension

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.


🧠 Key Concepts

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.

📘 Specification Alignment

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.


📦 Installation

Install the library via the .NET CLI:

dotnet add package A2A.AgentEcosystemExtension

or include it in your project file:

<PackageReference Include="A2A.AgentEcosystemExtension" Version="1.0.0" />
