Skills
Handler
Use when building, testing, or operating agentic systems that use the A2A protocol. Reach for Handler when you need to send messages to A2A agents from scripts or CI, manage conversations and tasks from the terminal, configure production authentication (bearer, API key, mTLS, OAuth2), inspect agent capabilities, or expose A2A operations through MCP for other agents.
