This skill provides the foundational A2A protocol knowledge Claude needs whenever a user wants to communicate with an A2A-compliant agent, call a remote agent by URL or alias, understand how agent cards work, integrate an agent-to-agent connection, construct an a2a CLI command, list or poll task status, cancel a running task, or subscribe to task updates. Relevant when the user mentions "A2A protocol", "agent card", "remote agent", "agent endpoint", "agent-to-agent", "a2a CLI", "use an agent", "call an agent", "ping an agent", or needs to understand task lifecycle states.
