An example result is the completed payload, not a JSON-RPC response or a pending workflow. Remove envelope fields such as jsonrpc and id and do not include task or input-required state. Multi-step interactions belong in the explicit interaction example structure.

## Requirement

An example result is a completed result payload: it contains no JSON-RPC envelope field and no non-completed workflow field.

## Notes

Envelope fields are jsonrpc, id, and error. Non-completed workflow fields are task, inputRequests, and requestState. They are excluded from the field classification of mcp.result.additional-properties.preserve.
