DEFINITION
Context Window Stress
Context Window Stress / Context Pressure
Definition
The degradation in LLM reasoning quality and tool calling accuracy when operating near or at the limits of the model's maximum context window. Long-horizon agent simulations accumulate conversation history, world state, and reasoning traces that stress this limit.
Examples in the Wild
- Example 1:An agent's decision quality declining as world history accumulates over 48 hours of simulation
- Example 2:Tool calling becoming less reliable as context fills with prior agent interactions
- Example 3:Agents forgetting earlier commitments or rules as context window fills
- Example 4:Different models showing different degradation patterns under context pressure
