Write the context budget
max_context_tokens is the whole window, reserved_output_tokens is what the answer needs, and truncation_strategy says what gives way first.
echo 'max_context_tokens: 128000\nreserved_output_tokens: 2000\ntruncation_strategy: drop_oldest_history_first' > ~/prompts/context-budget.yaml - 2 locked · each failed submit reveals one
