# Member inspection (llmcpp)

**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:

```json
{
  "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.
