Design A2A Agent Card

Skill Verified Active

Design an A2A Agent Card (.well-known/agent.json) manifest describing agent capabilities, skills, authentication requirements, and supported content types. Use when building an agent that must be discoverable by other A2A-compliant agents, exposing capabilities for multi-agent orchestration, migrating an existing agent to the A2A protocol, defining the public contract for an agent before implementation, or integrating with agent registries that consume Agent Cards.

Purpose

To help developers create discoverable and interoperable agents by designing standardized A2A Agent Cards that clearly define their capabilities and contracts.

Features

  • Design Agent Card identity and description
  • Enumerate skills with input/output modes
  • Configure authentication schemes (none, apiKey, oauth2)
  • Declare agent capabilities (streaming, pushNotifications)
  • Validate and publish the Agent Card

Use Cases

  • Building an agent discoverable by other A2A-compliant agents
  • Exposing agent capabilities for multi-agent orchestration
  • Migrating an existing agent to the A2A protocol
  • Defining the public contract for an agent before implementation

Non-Goals

  • Implementing the actual agent server behind the Agent Card
  • Validating the security of authentication credentials
  • Automating the publishing of the Agent Card to agent registries

Workflow

  1. Define Agent Identity and Description
  2. Enumerate Skills with Input/Output Schemas
  3. Configure Authentication
  4. Specify Capabilities
  5. Validate and Publish Agent Card

Practices

  • Agent contract definition
  • Interoperability standards
  • API documentation

Test A2a Interop

100

Test A2A interoperability between agents by validating Agent Card conformance, exercising all task lifecycle states, and verifying streaming and error handling. Use when verifying a new A2A server implementation before deployment, validating interoperability between two or more A2A agents, running conformance tests in CI/CD for A2A services, debugging failures in multi-agent A2A workflows, or certifying that an agent meets A2A protocol requirements for a registry.
