So this is really weird, I was using OpenClaw with GPT 5.4 via Codex on I think Friday of last week, and I noticed what looked like thinking tokens spilling to the main chat, and it sounded a lot like this trick! Couple of examples of what I was seeing in the output:

"Need resume task. No skill applies clearly. Need maybe memory? prior work yes need memory_search.” "Need maybe script content from history. Search specific.”

Possible that OpenAI has come up with something very similar here?

Edit: looks like not only me, https://github.com/openclaw/openclaw/issues/25592#issuecomme...
