Clarify that subagents inherit the parent model unless explicitly configured

[tryonelove]

Hello,

I'd like to propose a clarification regarding spawning a cheaper model. If you want an agent to run with a cheaper model, you need to explicitly provide that model. Otherwise, the agent inherits the parent conversation's setup.

I've been testing the skill for a couple of days and noticed that neither Codex nor Claude Code spawns a cheaper model unless the model is explicitly provided.

Docs:

• Codex - Although the subagent docs say Codex can choose the model by itself, I’ve never encountered a case where I start with 5.5-xhigh and it spawns an agent with a different reasoning effort to reduce cost.
• Claude Code - Seems like Claude Code cannot spawn cheaper models until an explicit model is provided.

So, right now, if you start a session with an expensive model, it spawns an agent with the same config, which is not required at all and contradicts this statement.
