Where should the agent card be hosted?

Following protocol standards, it is recommended to host the agent card at the `/.well-known/agent.json` or `/.well-known/agent-card.json` path on your service's domain.

How do I validate my agent card configuration?

The skill includes a `validate-agent-card.sh` script that checks your JSON structure against the official A2A schema for required fields and formatting.

Can I define custom skills in the agent card?

Absolutely. The templates include a robust 'skills' array where you can define custom identifiers, descriptions, and JSON Schemas for both inputs and outputs.

What is an A2A Agent Card?

An Agent Card is a standardized JSON manifest that defines an AI agent's identity, metadata, capabilities, authentication requirements, and service endpoints for discovery by other agents.

Does it support complex authentication like OAuth2?

Yes, the templates provide specific configurations for multiple security schemes, including OAuth2 flows, Bearer tokens, Basic Auth, and API keys.

API開発

Generates standardized Agent-to-Agent (A2A) protocol manifests using validated JSON templates for discovery, security, and capability definition.

This skill provides a comprehensive suite of JSON templates and validation tools for implementing the A2A (Agent-to-Agent) protocol. It enables developers to quickly generate compliant agent cards that define identity, security schemes (such as API keys, Bearer tokens, and OAuth2), and specific agent skills with detailed input/output schemas. By providing structured templates for various agent types—from basic implementations to multi-capability and streaming-enabled services—it ensures seamless discovery and interoperability between AI agents in a decentralized marketplace.
