Member inspection exposes a class's fields, methods, constructors, nested types, and bases. The repository tests query Account with list_members; an external agent sends:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "list_members",
"arguments": {
"type": "Account"
}
}
}
The fixture's class has a public balance() method and a private cents field. Access is reported from the generated body's location: the generated deposit method can modify private state, while the external printing function should use the public interface.
The agent can then check a proposed operation with try_compile. Members describe available structure, not the class's complete behavioral contract. A writable field may participate in invariants that the request and tests must make explicit.
