What issue are you seeing?

0.113.0 introduced a regression in multi-agent handing. Previously, if an agent's developer prompt contained instructions to spawn sub-agents, it would do so. Now what I see happening is that an "Orchestrater" agent is spawned of the correct type, when then spawns another agent of the same type, which then spawns the desired sub-agents.

What steps can reproduce the bug?

Uploaded thread: 019cdaa2-05c5-7c51-97ce-79c3528a2017

1. Spawn an agent that spawns specialized sub-agents
2. Codex then spawns an "Orchestrater" (A0) agent that then spawns the same agent (A1) again
3. Agent (A1) then finally spawns the specialized sub-agents

What is the expected behavior?

The spawned top-level agent uses the developer_prompt as written and then spawns the specialized sub-agents.
