Context window suitcase
Weigh the tradeoffs
More evidence can help and can crowd out instructions. Summaries save space and can drop obligations. Long windows raise cost and attention dilution risk.

The live tension
More evidence can help and can crowd out instructions. Summaries save space and can drop obligations. Long windows raise cost and attention dilution risk.
Translate into user impact on the contract-review assistant when tuning context window. Which error class costs more—missed catches, slower answers, higher spend, or privacy exposure? That ranking picks the default more honestly than a blog’s recommended settings for context window.

Numbers that force honesty
A 32k window with 8k system+tools, 12k retrieved exhibits, 6k history leaves ~6k for the draft—and less if tokenization is heavier than word count suggests. Scoped specifically to context window / contract-review assistant / tradeoffs.
If the aggressive context window setting wins the headline metric while breaking a protected slice or blowing the latency budget on the contract-review assistant, it is not a win. Record intended gain and tolerated regression together for context window.

Make it operational
Revisit the context window tradeoff when traffic shape changes on the contract-review assistant. A setting that was right at low volume can fail when a new language segment or document length appears. Tradeoffs expire; re-measure on a calendar, not only on incidents.
Also pin one numeric memory from this context window chapter: A 32k window with 8k system+tools, 12k retrieved exhibits, 6k history leaves ~6k for the draft—and less if tokenization is heavier than word count suggests. That number is not decoration; it is a template for how claims about context window on the contract-review assistant should look in design docs. Scoped specifically to context window / contract-review assistant / tradeoffs.

Common mix-ups
People confuse context window with neighboring buzzwords when debugging the contract-review assistant. Before changing prompts, ask whether the broken stage was evidence gathering, the context window judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried context window and it failed”) that blocks the next team on the contract-review assistant. Scoped specifically to context window / contract-review assistant / tradeoffs.

Rehearsal (context-window/tradeoffs)
Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to context window rather than generic AI advice.

Why this matters
For the contract-review assistant, name one regression you will tolerate when pursuing the main benefit of context window, and one regression that is stop-ship.
