…sult Add human-readable string representations to MultiAgentResult and NodeResult, consistent with the existing AgentResult.__str__ behavior. NodeResult.__str__ delegates to its inner result (AgentResult, MultiAgentResult, or Exception). MultiAgentResult.__str__ prioritizes interrupts, then outputs each node's text prefixed with its name. This makes print(result) produce clean output instead of the default dataclass repr. Closes strands-agents#1561

Assessment: Approve Clean implementation that follows the established Review Details
Suggestion for improved test coverage: Consider adding tests for:
Example tests: def test_multi_agent_result_str_multiple_nodes():
"""Test MultiAgentResult.__str__ with multiple nodes."""
ar1 = AgentResult(
message={"role": "assistant", "content": [{"text": "Response 1"}]},
stop_reason="end_turn", state={}, metrics={},
)
ar2 = AgentResult(
message={"role": "assistant", "content": [{"text": "Response 2"}]},
stop_reason="end_turn", state={}, metrics={},
)
result = MultiAgentResult(
status=Status.COMPLETED,
results={"node1": NodeResult(result=ar1), "node2": NodeResult(result=ar2)},
)
output = str(result)
assert "node1: Response 1" in output
assert "node2: Response 2" in output
assert "\n" in output
def test_node_result_str_with_nested_multiagent():
"""Test NodeResult.__str__ with nested MultiAgentResult."""
inner_ar = AgentResult(
message={"role": "assistant", "content": [{"text": "Nested response"}]},
stop_reason="end_turn", state={}, metrics={},
)
inner_mar = MultiAgentResult(
status=Status.COMPLETED,
results={"inner_node": NodeResult(result=inner_ar)},
)
outer_node = NodeResult(result=inner_mar)
assert "inner_node: Nested response" in str(outer_node) |
…esult Add two additional tests addressing review feedback: - Multiple nodes: verifies for loop and newline joining - Nested MultiAgentResult: verifies recursive delegation in NodeResult
