What issue are you seeing?

I have Codex maintain notes files that summarize where we've gotten to within each session. This allows me to chain sessions together in such a way that I wind up using fewer tokens to solve problems. I know the 'compact' feature exists, but it's opaque, and therefore I don't fully trust it when dealing with difficult problems. It would be very useful if the LLM knew which session ID was currently running, because then I could have it refer to the session by ID when writing the notes.

What steps can reproduce the bug?

Chat to the model and ask it for the session ID - e.g.

› Hi!

• Hey there! How can I help today?

› What's the session ID for this chat?

• I don’t have access to any session ID or similar identifier for this chat.

What is the expected behavior?
