Context Engineering

I would love to have better control over the contents of the context for a thread. In priority order:

A currently used / remaining indicator (10,531 tokens of 128,000 used) with warning indication when it’s too full (eg. green → yellow → orange → pink → red).

Summarize thread. Let me replace the thread with a summary of the thread so far.

Let me manually add key points that I want in the thread.

Let me manually delete elements of the context.

Let me re-order the context window.
