Work with the a2a-java SUT (System Under Test). Use when the user wants to regenerate the Java SUT from Gherkin scenarios, build it, run it, or test it with the TCK.
Work with the a2a-jakarta SUT (System Under Test). Use when the user wants to regenerate the Jakarta SUT from Gherkin scenarios, build it, run it, or test it with the TCK.
Work with the a2a-python SUT (System Under Test). Use when the user wants to regenerate the Python SUT from Gherkin scenarios, build it, run it, or test it with the TCK.
Diagnose a TCK requirement failure and draft a GitHub issue with the requirement context, failure details, and a curl reproducer. Use when the user wants to report a failing requirement, understand why it failed, or create a bug report for an SUT implementor.
Help an SDK implementor run the A2A TCK against their System Under Test (SUT). Use when the user wants to validate their A2A agent implementation, debug TCK failures, or understand conformance results.
Interact with remote AI agents using the A2A (Agent-to-Agent) protocol as a client. Use this skill whenever the user wants to communicate with an A2A agent, send tasks to a remote agent, discover agent capabilities, check task status, or get results from an A2A-compatible service. Trigger on mentions of A2A, agent-to-agent, remote agents, agent cards, or when the user provides a URL to an A2A agent endpoint.
Learn about a specific TCK requirement. Use when the user asks about a requirement ID (e.g. CORE-SEND-001, GRPC-ERR-001), wants to understand what it tests, or needs to find the spec section, tests, and validators related to a requirement.
Update the A2A TCK when the A2A protocol specification changes. Use when the user mentions updating the spec, syncing with upstream A2A, or when a new version of the A2A protocol is released.
