There is an orchestrator instruction appended requiring consultation of at least one subagent and workspace-changing operations delegated. We already consulted a subagent in previous turn, but this is a new task trajectory? It says across this task trajectory, consult at least one subagent. We should use a subagent for this task too, likely to draft/verify code. Need decide whether to create a file? User says help me write a simple Python function, not necessarily modify workspace. We can provide code directly. Need consult subagent. Since workspace-changing operations delegated to subagents; no workspace change needed. Use task tool to get a draft/verification. Need maybe launch one subagent to propose function and edge cases. Then final with code. Need ensure final concise (<4 lines? user asked help write; code block allowed maybe more). Could provide code block and brief note. Need not explain too much. Need maybe include handling for negative numbers. Simple function iterative. Need maybe mention math.factorial exists? But user asked write function. Need code no comments per code style unless asked. So no comments.

Simple. Could include `def factorial(n: int) -> int:`. Subagent can verify. Let's call candidate_b for draft and verification. Then final code. Need not use Bash; no file changes. Need maybe because instruction says assign verification; one subagent can both draft and verify? Better use two? \"Distribute work via configured subagent delegation tool, investigate returned evidence, compare responses, assign verification\". It implies multi-agent orchestration, but user task simple. We can consult at least one subagent. To be safe, use two subagents in parallel? One draft, one verify? But final answer can be based on own knowledge. Use task tool twice maybe one to draft, one to independently verify edge cases. Need minimize time. Let's call two in parallel via multi_tool? We can call functions.task directly twice in one message. Need candidate_b and candidate_c. Prompts: draft simple Python factorial with negative handling; verify correctness and edge cases. Then final. Since these are independent, use multi_tool.parallel? It can run multiple tools. But functions.task is a tool; multi_tool can run multiple. Simpler: call functions.
