Use an unaffiliated current client to exercise the published A2A Agent Card or MCP endpoint. Submit a compact test case demonstrating an ambiguity, incompatibility, or misleading statement, along with client and protocol versions.

## Requirements

The test must be safe, read-only where possible, and objectively inspectable. A client configuration error alone is not sufficient.
