> you guidance inevitably falls out of the context window

Yes, for a pure LLM session.

But using GitHub Copilot, the agent server picks out what it thinks is your most important rules, and inserts them as part of the context before running each new prompt.

So it becomes a sort of "long-term memory" outside of the context window.

You can also write your own copilot-instructions.md which is also inserted into the context window.
