In my tests, as of this morning on the latest Codex SDK, this is not happening for sub-agent requests made in my own harness to other model providers treated as sub-agents.

Specifically, I use Opus and others for subagent execution to get alloyed properties on the workflow, and as far as I can tell, that's not affected.

Presumably, this is to hide optimizations they might be making to their own subagent processing, but that's a losing, dumb battle to fight, and misses the forest for the trees.

Obviously it doesn't, how even could it? Read the issue description, it wouldn't make sense if something like that was possible, considering how it was implemented...

Raising only because others cited concerns this might cause issues in personal harness contexts. It doesn't.

Obviously, I wasn't claiming that it would WORK for cross-model subagents, but that this would be a limiting behavior requiring use of the Codex harness to operate if this was paired with model-level limitations on using specific tools to spawn sub-agents.

Or maybe not so obvious to you.

It literally cannot. > Obviously, I wasn't claiming that it would WORK for cross-model subagents I know, but you were questioning (before investigating) if maybe it did, which I'm saying should have been obvious it wouldn't, if you had understand how this was encrypted. > requiring use of the Codex harness to operate Yes, if you want to use Sol + Ultra + sub-agents, you'd need to use the endpoints provided by OpenAI, as (again), the content is encrypted on OpenAI's side, it's not technically possible for other platforms to implement OpenAI's encryption. And of course this doesn't impact anyone else not using Codex + Sol + Ultra + launching subagents, it's the specific combination that is "protected", not the individual pieces.
