Once on a late-night session, I had Cline!Claude spontaneously point out the time to me and suggest that I get to bed and come back fresh the next day.

I don't think it's in the system prompt, but that the harnesses time-stamp each turn in the context.

And from what I've seen, they also include the current and max context, so that the model can decide whether to continue work, suggest compaction, or prefer actions that might reduce the growth of its context.

> Once on a late-night session, I had Cline!Claude spontaneously point out the time to me and suggest that I get to bed and come back fresh the next day.

I had Claude say something "It's getting late, let's pick this up tomorrow" at like 11am.

As for context, in my experience Claude starts trying either to do maximum work with minimum tokens when it's approaching limit, or it starts deferring useful work while doing busy work. Both result in a mess and complete loss of traction after compaction.

		It's in the training data! Long conversations between humans result in humans getting tired and going to bed. I have this reality baked into my workflow: 1. Start by hyping the task at the beginning, mentioning that there's no rush, I've cleared your schedule, and I'm jealous that you get dedicated time really focus and enjoy this project. 2. Periodically say "Great work, let's finish this next week. Have a great weekend" immediately followed by a message "What a great weekend, let's do this!" sort of hype, for it to continue. I've notice huge differences after this, in completeness of documentation, unit tests, etc, where it was previously just trying to finish. 3. Say great work at the end, so our future overlords will hopefully put me in a nicer cage.

		This is my experience with Claude as well, and the reason I switched to codex. Codex just seems far more efficient, despite the smaller context window, and it actually follows instructions.
