Reserve answer capacity
Subtract the intended response allowance from the usable model context before adding input material.

How it works
Add each context group
The tool totals instructions, code, logs, documentation, and examples against the remaining budget.
Reduce the largest low-value group
Keep exact task signals and summarise repeated, generated, older, or unrelated material first.

Frequently asked questions
How do I know the exact token count?
Use the tokenizer for the specific model when available. Character and word conversions are approximations and vary by language and content.
Should I always fill the entire context window?
No. Relevance and clarity matter more than fullness, and the model needs room to reason and return the requested output.
What context should remain verbatim?
Keep exact instructions, relevant interfaces, failing errors, important constraints, and small representative examples when wording affects the task.
