Module: RubyCoded::Chat::State::ContextWindow

Included in:
RubyCoded::Chat::State
Defined in:
lib/ruby_coded/chat/state/context_window.rb

Overview

Resolves current model context window and computes live context usage based on the last turn's server-reported usage block. This reflects the size of the prompt actually sent to the model on the most recent request, not the total tokens spent in the session.
